dbuezas / arduino-web-timers Goto Github PK

Let me start by saying ...Wow, wow and wow about the elegance of this tool. I think this will help a lot of people, also as a learning tool to grasp what timers actually do.
You asked for some feedback, and the only thing I found for now is that I can use Chrome or Opera as a browser to have the slider working. My Firefox browser won't let me use the slider for setting the OCRxA/B value(s).
This on a Windows10 PC.

I used this configuration.

  TCCR2B = 
    1 << CS22;
  TIMSK2 = 
    1 << OCIE2B |
    1 << OCIE2A |
    1 << TOIE2;
  OCR2A = 50;
  OCR2B = 150;
  interrupts();
}

Somehow on my controller, TCCR2A was set to 1 but it should be 0.
I added TCCR2A = 0; to the code and it works fine now.

Maybe add TCCR2A = 0; in normal mode?

After you (@dbuezas) mentioned your Arduino Web Timers App, I tested it with Firefox. The result is here:

Timer 1:

I'm not tested, but in my opinion the correct program code would be:

  PMX0 = 
    1 << WCE;
  PMX0 = 
    1 << C1BF4;

Like setting of the clock prescaler register WCE meaning: update enable then update.
PMX0/1update: Must write logic one to WCE. In the following 6 system clocks PMX0/1 update will be finished by writing the register.

Timer 2:

In my opinion the correct program code would be:

  PMX0 = 
    1 << WCE;
  PMX1 = 
    1 << C2BF7;

Timer 0, no port switching code:

Timer 3 looks good code:

This warning is seen in the console:

useHash.ts:11 Throttling navigation to prevent the browser from hanging. See https://crbug.com/1038223. Command line switch --disable-ipc-flooding-protection can be used to bypass the protection

Clock/prescaler/top

always with lgt8f328p with 1.0.6 and arduino ide 1.8.15
I have try the timer 0 on normal mode with toggle ..no toggle but never have an output ??? i have block the normal loop to avoid arduino core to use timer0 because i was thinking this block the direct use of timer0 but same things.
This work with timer3..

It is a bit hacky and not performant.

Idea:

• Use debounce {leading: false, trailing: true} to set the full hash
• Don't react to hash changes unless they are truly different than the current state
• Never set the hash directly (e.g to set defaults or to change timer index or mcu). Instead add the defaults internally when reading the hash. This makes the defaults implicit.
• Get rid of userConfigState_internal

Hi again . with timer 0 any output and build failed on all mode
if i set the dead time with lgt328

Hi,

many thanks for your very helpful work!
It's also a very good tool to train somebody.

Within arduiono-web-timers scripts, the definition of the Clock Control Status Register is 'TCKSCR'.
Within your lgt8fx arduino board package it is 'TCKCSR'.

I agree, the definition in the data sheet is confusing ;)

These two are generating the same code:

https://dbuezas.github.io/arduino-web-timers/#mcu=LGT8F328P&timer=3&topValue=0xFFFF&interruptA=on
https://dbuezas.github.io/arduino-web-timers/#mcu=LGT8F328P&timer=3&topValue=OCR3A&interruptA=on

This seems to be because the first viable option for timer mode is not propagated to the code unless explicitly selected.

D1, B2, etc are not defined in standard atmel arduino core.
Pins B are mapped to D8-13 in lgt

e.g: https://dbuezas.github.io/arduino-web-timers#mcu=LGT8F328P&timer=3&OCR3A=51858&topValue=OCR3A

Hello! Thanks for your software...
In Normal Mode (ATmEga328P), when select TOGGLE on OCA/B the code are

TCCR2A =
1 << COM2A1 |
1 << COM2B1;
TCCR2B =
1 << CS22 |
1 << CS21 |
1 << CS20;
But must be 1 << COM2A0 |
1 << COM2B0;
Best regards...

See here dbuezas/lgt8fx#245 (comment)

This will very good to add an input for set the frequency source of timer that the graph use to displays the event and to have the timing on the graphic scale numbers to be able to see the timming event like
the "real world" case of the board... 16Mhz board..8mhz... or for some special case with some quartz with special frequencies very very less usual but sometime very interesting to have the microcontrollers to "BPM" exactly to this special frequencies...
So if done many time will be win with web timer to have the goods settings to have the timer good real life timing found...

When I played with arduino-web-timers, I noticed the Timer 0 dead time can only be adjusted to maximum 15. I looked out why.
So I noticed the generated code has a bug.

  TCCR0A = 
    1 << COM0A1 |
    1 << COM0B1 |
    1 << WGM00;
  TCCR0B = 
    1 << DTEN0 |
    1 << CS00;
  DDRD = 
    1 << DDD5 |
    1 << DDD6;
  OCR0A = 59;
  OCR0B = 110;
  DTR0L = 11;   <-- There are no independent DTR0L and DRT0H registers
  DTR0H = 9;

DTR0 = (9 << 4 | 11) is (9 * 16 + 11) is (155)

I think the correct setting of the Timer 0 DTR0 register for the example above is:
DTR0 = 155;

https://dbuezas.github.io/arduino-web-timers/#mcu=LGT8F328P&timer=0&DeadTime=on&DTR0H=9&DTR0L=11&OCR0B=110&OCR0A=59

Hello many thanks for this wonderfull timer configurator.
I do some try.
The pinout is quiet difficult to find the real pin .. perhaps add arduino pin number or physical of lgt qfp48 and 32 ???

I have want to put Dead time on timer 3 with pcpwm mode but at build time
this report not valid in this scope...

I have try same setting for timer 3 with FPWM mode this build ok.

My device is wavgat avga328p clone minipro.
Have a nice day.
