pimoroni / automation-hat Goto Github PK

I've tried both manually compiled python and linuxbrewed python and neither one seems to work (meaing the import doesn't work) after I install with pip3 install automationhat. I think the problem comes from the back that smbus isn't installed and I can't find a way to install that.

ADC reads wrong values every now and then. The problem is fixed by disabling the auto LED updating, so I’d guess both the LED update thread and the user thread start an ADC read around the same time, which results in the wrong ADC channel result being returned to one of them.

With a fresh install of raspbianI tried to use this example file. I had no hat attached and had never attached a hat. I still see that it detected one and promptly failed.

Seems like thats an error with detecting that the hat is connected.

relay.three works with the write command but it will not work with the toggle command. I've reinstalled everything and relay three will still not respond to the toggle command.

I've tried pip install and just downloading the git and running setup, but still a no go.

Found the answer: curl -sS get.pimoroni.com/automationhat | bash

Odd, I had tried that first as a guess from other Pimoroni products and the path was not found. Maybe just network problems at the moment.

I can .toggle() relays, but toggle does nothing for comms, warn, outputs. on() and off() work fine. No error message. Just nothing happens. Does it not know current "state" to toggle from/to?

Is there any way to set the default for output to high or invert?

HAT Mini was not working after install instructions.

These steps were needed to get the IO and the relay running. I still can't get the display to work

1. pip3 install gpiodevice
2. enable i2c & spi
3. fix some changes in display initialization
   https://forums.pimoroni.com/t/issue-with-enviro-with-rpi-zero-display-and-particles-not-working/23365/15

this is how far i got. I removed the display stuff for now so i can at least operate the relay. these are the error messages:

I have a Hat with the new ADS1115 chip. Out of the box, the analog inputs were all screwed up using the mfg supplied library.

Tested analog inputs utilizing onboard 5V and examples/hat/inputs.py.
When no inputs are not connected, 'one' reads 4.42V and led 1 is on.
When 5V connected to input 1: 'two' reads 5.16 and led 1 & 2 are on.
When 5V connected to input 2: 'three' reads 5.17 and led 1 & 3 are on.
When 5V connected to input 3: 'four' reads 0.66 and led 1 is on.

Found solution with two edits to ads1015.py described here:
https://forums.pimoroni.com/t/automation-hat-analogue-in-spurious-reading/10749/7

More of a question before I look to make changes and submit a PR.

The Automation HAT features a 12-bit ADC, thus there are 4096 values:

• 24V ADC, max voltage 25.85 a single bit is 0.0063 per bit
• 3.3V ADC, max voltage 3.3 a single bit is 0.000806 per bit

In order to show the resolution represented by each bit shouldn't the output be to:

• 24V ADC: minimum of 3 Decimal places
• 3.3V ADC: minimum of 4 Decimal places

Surely part of the purpose of ADC4 is to provide a higher resolution for lower voltage measurements?

Anyone wanting to handler a lower resolution can round the result themselves. Right?

I was seeking to implement ADC4 support in my Node-Red module for the Automation HAT and have the groundwork in place. However, it appears that the library is not providing sensible readings for the 3.3V ADC4.

• Connecting ADC4 to GND, gives readings of: 0.58 - 0.59
• Connecting ADC4 to 3v3, gives readings of: 0.63 - 0.65

I only have a single Automation HAT to test against, so can't rule out hardware, though I think it's unlikely as I'd never used those headers until today and I seem to recall they always gave low/odd readings which was why I excluded it from my initial implementation.

Environment:

• Raspberry Pi 3 Model B
• Raspbian Buster (Linux pi3-red 4.19.75-v7+ #1270 SMP)

From there I can attach the hat and run an example.

I am looking into this hat due to its capabilities but one of the things I am unsure about is it's way of connecting to the GPIO pins. I cannot seem to find a photo that shows how it connects to the I2C pins, voltage pins, and GPIO pins does it sit on top of the pins like some other relay boards? Can someone show me their setup? it is very important to me because this will be used in an industrial setting. Any photos or clarification on how it connects to the raspberry pi will be much appreciated and helpful.

are relays accessible by integer value or by name/word only.

for example:

is:
automationhat.relay[i + 1].on() supported in a for loop?

or must you spell out the name such as

automationhat.relay.one.toggle()

See: https://forums.pimoroni.com/t/automation-hat-node-red-nodes/6640/2

Line 29 is:
image = Image.open("images/outputs-blank.jpg")

This is a relative link, which crashes the example when it moves from the target location where installed by the Pimoroni installer.

This replacement line allows this example to be portable when installed that way:

   "/home/pi/Pimoroni/automationhat/examples/hat-mini/images/outputs-blank.jpg")

Hi,

I have an automationHAT sitting on an RPi3 that's doing a bunch of stuff with relays. I need to hook a doorbell into the system and sense the button presses. I wired the positive lead to 5V and plugged the other side into the buffered input with the pull-down resistor turned on via:

GPIO.setup(21, GPIO.IN, pull_up_down=GPIO.PUD_DOWN).

Right now I have a loop running in a thread to check the input state every .05 seconds. It works but I'd like to move to:

GPIO.add_event_detect(21, GPIO.RISING, callback=myCallback)

but the code never gets the rising event. Is the use of the rising event supported when using a PIN connected to the buffered input? If not, do you have another way that would be better than polling? The CPU is also doing a bunch of transcoding work for other automations so I'm eager to not tax the CPU with the loop.

Thanks!

Analog.py fails to run with a syntax error on Python3 < 3.6 because the following f-string requires python3 >= 3.6:

Fix:
change:
line above to:

draw.text((text_x, text_y + offset), '{:.2f}'.format(reading), font=font, fill=colour)

or to force users to py3 >=3.6 by changing this line to "3.6":

PS. would be good to mention somewhere the user needs to enable SPI and IC2 with raspi-config ...

Hi there,

I am not able to get the display to work. Neither the examples here nor the ones over at the st7735 library work. Using the proposed install script (after disabling the externally managed env) still delivers the old examples where 9 instead of "GPIO9" is used as dc parameter.

According to the pinout (found at https://pinout.xyz/pinout/automation_hat_mini), the config below should let me control the display:

# Create ST7735 LCD display class. disp = st7735.ST7735( port=0, cs=st7735.BG_SPI_CS_FRONT, dc="GPIO9", backlight="GPIO25", rotation=90, spi_speed_hz=4000000 )

However it always results in the following output:

Woah there, suitable gpiochip not found!
❌ GPIO9: not found - /dev/gpiochip1 (raspberrypi-exp-gpio)!
❌ GPIO9: not found - /dev/gpiochip0 (pinctrl-bcm2711)!

HELP! SPI is enabled via raspi-config. I am running the latest release of headless rpi os 64bit (debian bookworm) as of today on a RPi4 with 4GiB of RAM.

The output of gpioinfo looks like this (I am not an expert but the display isn't there I guess):

For no particular reason... nude nudge wink wink...

I'm in the process of implementing node-red support for the Automation-Hat. Looking at the input side, this python library only supports reading the inputs. Is there a reason that the automation-hat library doesn't support the analog changed event, and the digital input changed, high and low events.?
Interestingly the input handler also include debouncing the digital inputs

Any chance this could be added, or is there a reason for this difference? Thanks

Was analog output support for A1-A3 never added on the automation hat mini because of an electrical issue or because of lack of software support? Having analog output on this board would help me a lot, I'd be willing to create a PR to add support if I can get schematics and any other relevant info to it

Hello! I bought recently an AutomationHat to use the ADC channels. However, I see wrong data 0.03v or 4.7V spikes when measuring constant data.
i thought this was fixed in the past but I still see this with latest library release.

What can I do?

I want to mill out some boards and realized that you do not publish the brd files of your boards ...

I am doing a project for the company I work for to monitor when our shop doors are locked as well as collect temperature data. There is a prox sensor in each of the doors that monitors when the dead bolts are locked. They are 24V prox sensors that run 24V to their respective inputs on that hat when the door is locked. I have four doors, three of which are connected to the digital input and the fourth is connected to the first input of the ADC. The temperature reading is connected to the second ADC input. I created a threshold for the temperature to cure its random spikes and dips from the misreading of the hat, but ultimately cannot do the same for the door that is connected to the first ADC input. I have read different threads about how the LED is what is causing the issue, but I don't even power an LED in my code and it still doesn't work properly. I have attached an image of the graph of 48-hours of a door that has been locked the entire time that is never used. I have also attached an image of my python code.

You provide a python interface, but no C library etc. I'm trying to interface from C# via wiringPi by reverse engineering the python code, but cannot get images to appear. Could you provide a document listing all the control commands and GPIO pins (eg CS) that are relevant, and show the waveforms required to make it work?

The documentation file doesn't seem to mention the buffered input ports

The installer currently misses a lot of the dependencies needed to run the Automation HAT Mini examples (particularly on Lite) - it would be great if it could automatically check for:

spidev
pil
st7735
numpy
font-roboto

I also had to turn on I2C and SPI manually for the AHM examples to work.

Latest scripts include using the LCD on the Mini Hat. The scripts included in get.pimoroni.com/automationhat don't have these features.

Using PiZeroW (I know, old but what I had..)
Used following guide to install nodejs on PiZeroW:
https://hassancorrigan.com/blog/install-nodejs-on-a-raspberry-pi-zero/
Installed Pimoroni software as documented on their site.
Enabled I2C via sudo raspi-config

Tried to run output.py and generated error: No module named 'gpiod'

same error: No module named 'gpiod'
googled more and installed: sudo apt install libgpiod-dev python3-libgpiod
different error: No module named 'gpiodevice'
googled more and installed: sudo pip3 install ST7735

Any suggestions? I've searched throughly.

Hi,
after a fresh install of Raspbian Stretch (kernel 4.14) I'm unable to make the AutomationHat work. It seems that the RPi can't pickup the board.

Hi, after falling the instructions from the tutorial on pimoroni.com I get the error below when trying to run the example.

I'm not great with Python but it seems pretty straight forward that a package called "st7735" might be missing, so I punched it into Google and found the ST7735 module. I get a small error below mentioning that python-imaging isn't available, I have opened an issue on their code base too to be complete but I'm mentioning it here since it is part of the install process I needed to follow to get everything working. (However, in the end I did get the example working even without python-imaging or manually installing python-pil as it suggests may be needed.)

is only available from another source
However the following packages replace it:
  python-pil

E: Package 'python-imaging' has no installation candidate

The final error I encountered was this:

pi@pizero:~/Pimoroni/automationhat/examples/hat-mini $ python3 output.py
output.py

This Automation HAT Mini example toggles and displays the
status of the three 24V-tolerant digital outputs.

Press CTRL+C to exit.

Traceback (most recent call last):
  File "output.py", line 52, in <module>

    self._spi = spidev.SpiDev(port, cs)
FileNotFoundError: [Errno 2] No such file or directory

I wasn't sure what this was so I just enabled the SPI through raspi-config's interface options and now the example works just fine.

I zsee the hat in i2cdetect, the screen gets some sort of "snow" pattern on the oled display, and then i get a remote i/o error

any help appreciated, brand new install, fresh pull from the github

Hi there! I've just received my automationHAT and everything works as expected expect that none of the lights are responding.
Neither any input/output/relay lights are coming up, nor can i control the power/comms/warn lights.
I'm using v0.4.1.
Any ideas?
