pwm pins ? servo and pwm conflict ? max pin count in plugin ?

[tfoutfou]

Hi

Just some questions to clear a few things.

1)Is there a changelog for the betas ?

2)Why is the maximum PWM count is 25 ? i tried every simple pin and only the true PWM pins are working , this mean 2 to 9 , 11 to 13 , 44 to 46 , on my Mega , I was thinking i can use any pin as PWM but not ?

3) if i add a single servo pin , PWM dont work anymore on the board
is it normal ?
(didnt do a lot of test to really confirm this , but prety sure)

4) Why can we chose up to pin 70 in the plugin ? because the bigest board i can found is the mega2560 with only 54 I/O

Thank you very much

All changes should be listed in the user manual. If you want a smaller brake down I would have to make on up for you as there are lots of bug fixes.

Yes you can only use PWM outputs as per all Arduinos as this is a hardware feature.

3) if i add a single servo pin , PWM dont work anymore on the board

No this should work ok but it has been a long time since I tested servos so if it is not working I will have to test and fix it.

4) Why can we chose up to pin 70 in the plugin ? because the bigest board i can found is the mega2560 with only 54 I/O

I cant remember but a long time ago when this was all new I think someone wanted to use the arduino chip pin numbers and it has not been changed. I cant see how this can cause problems.

for servo output , i did a few new test , and its definitely not working
(only one random PWM pin + one random servo pin on the board and nothing else)

correct me if i am wrong , but servo control is PWM ?
(and we can do it on any pin right ?)

maybe some kind of conflict with servo manual PWM timing , and hardware PWM implemantation ?


from arduino.cc

One major disadvantage is that any interrupts will affect the timing, which can cause considerable jitter unless you disable interrupts. A second disadvantage is you can't leave the output running while the processor does something else.

concerning the 70 pins thats not a problem at all , i was just wondering if i could find bigger arduino's




anyway arduino boards are cheap , so i can have one different board for servo and PWM , so at the end of the day its not a true problem


Thank you very much for support

What pins are you using?

Note:The plugin has a limit of 8 Servo pins per board.Note:On boards other than the Mega, use of the library disables analogWrite() (PWM) functionality on pins 9 and 10, whether or not there is a Servo on those pins

Again I would need to check back as it was added a long time ago and I do not have access to this info at the moment.

Hello,

I want to try something with pwm but i cannot create a device for that with the V1.0.0.99
Also the servo device not created
Everything is working good my boards are working for a year now.
Is this something in my setup ! or is this a know problem.

Thanks Ed

This is strange it is working here. What is not working? Can you describe what is wrong. Can you send me a debug log? Are you sure it is not just filtered out of the device manager page.

Hello Greig,

Thanks for your quick response.

I feel so stupid that whas it .
I forgot to clik on device type.

Thanks for your support
