Hi, the arduino SPI API has changed and these lines in all 3 examples no longer work

 SPI.begin();
  SPI.setBitOrder(MSBFIRST);
  //CPOL = 0, CPHA = 1
  SPI.setDataMode(SPI_MODE1);
  // Selecting 1Mhz clock for SPI
  SPI.setClockDivider(SPI_CLOCK_DIV16);

They should be replaced with

  SPI.beginTransaction(SPISettings(1000000,MSBFIRST,SPI_MODE1));

In ecgRespirationAlgo.h the sample rate is set as 125 Hz

and the drdy pin pulses on my oscilloscope every 8mS as would be expected, however if I change this value to 2000 making it 2kHz which the AD1292R is capable of doing, the pulses are still 8 mS apart, is there another variable I need to change in order to change the sample rate of the device?

I've had a look through the files and can't see something that stands out as needing to be modified other than that value mentioned before, any help would be appreciated.

I'm using the breakout board not the shield.

Hi, I'm using an arduino nano 33 ble and the online Arduino ide which Arduino IDE version 1.8.13.
I've imported the libraries and can't get a single example to run, they compile (once the SPI initialisation is changed as per my previous issue). But they don't upload to my board successfully, it appears to mess up my COM port used by the arduino until I'm able to load another sketch onto the board.
I've tried with both the shield and the breakout board.
Do you have any ideas for things I could try?

With the ADS1292RIPBSR chip and the test example program, I'm experiencing an issue where the status remains unchanged when ECG leads are either plugged in or unplugged, even though I'm using the following code:
if (ecgRespirationValues.leadoffDetected == false)
The lead-off status remains unchanged.

This circuit perfectly works in all example code using Arduino nano every with this below connection:
////////////////////////////////////////////////////////
// | VDD | +5V
// | PWDN/RESET | D4
// | START | D5
// | DRDY | D6
// | CS | D7
// | MOSI | D11
// | MISO | D12
// | SCK | D13
// | GND | Gnd

AND USING THIS BELOW CONFIG:

const int ADS1292_DRDY_PIN = 6;
const int ADS1292_CS_PIN = 7;
const int ADS1292_START_PIN = 5;
const int ADS1292_PWDN_PIN = 4;
///////////////////////////////////////////////////////

But in example 2 computation only, pin gets change ( I use 6,7,5,4 instead for nano every)
const int ADS1292_DRDY_PIN = 26;
const int ADS1292_CS_PIN = 13;
const int ADS1292_START_PIN = 14;
const int ADS1292_PWDN_PIN = 27;

For which microcontroller, pin configurations are declared?

And I changed SPI for MEGA: MISO, MOSI, SCK with 50,51,52 but still doesn't work, only shows noise and leads error.
Tried all pin configuration but no results.
Kindly let me know the exact pin configuration for Arduino MEGA.

Hi,

According to the protocemtralAds1292r.cpp, the gain is 6, right?

However, it doesn't make sense to me why the gain are both 6 in the CH1SET and CH2SET because they are different.

Thanks
