nabontra / servotimer2 Goto Github PK

Hi there

Thank you for the library which is useful in cases of a Timer1 conflict. I have created an Arduino simulation page. Here is the link.
This will give an instant preview to the users of your library.

https://wokwi.com/arduino/projects/300615873789428234

I appreciate it if you could add this to your ReadMe file. Please let me know If I can create a PR for that. also, if you have time, it will be awesome, if you can share the feedback on the overall Arduino simulator as well.
Please let me know if you have any questions :)

Thanks!
Matititam

When I try to use the library with my arduino Mega 2560 it says it won't compile, but when I try it with a nano it does. I also might have downloaded the library incorrectly. I am also trying to use Servo.h with this library, I'm not sure if that is causing issues.

Hi, I tried to run the ServoTimer2 library on an Sparkfun Pro Micro board, (also on a Adafruit feather 32u4) with a 32u4 cpu 8 MHz, but doesn't work. The errors are:
Arduino:1.8.12 (Windows 10), Scheda:"SparkFun Pro Micro, ATmega32U4 (3.3V, 8 MHz)"

Hey nabonta,

Glad I found this library. I needed to use Timer1 on my uno for other things but also drive one servo. Wanted to keep my design simple and drive the servo with one pin and software. While using Timer1 and ServoTimer2, after I do my write(xxxx) I delay a bit to let the servo move, then issue detach() to let the servo "relax". If I want the servo to HOLD the position, then I do not detach(). This is how the <Servo.h> library works, but yours is acting just the opposite. I looked at your code compared to the other library but can't see why it's behaving this way. Have you run into this?

Replace this

TIMSK2 = 0; // disable interrupts TCCR2A = 0; // normal counting mode TCCR2B = _BV(CS21); // set prescaler of 8 TCNT2 = 0; // clear the timer2 count TIFR2 = _BV(TOV2); // clear pending interrupts; TIMSK2 = _BV(TOIE2) ; // enable the overflow interrupt

With this
`#if defined (AVR_ATmega8) || defined (AVR_ATmega8A)

TIMSK = 0;  // disable interrupts 
bitClear(TCCR2,WGM20);
bitClear(TCCR2,WGM21);
TCCR2 = _BV(CS21);
TCNT2 = 0;      // clear the timer2 count 
TIFR = _BV(TOV2);
TIMSK =  _BV(TOIE2) ; // enable the overflow interrupt	  

#else
TIMSK2 = 0; // disable interrupts
TCCR2A = 0; // normal counting mode
TCCR2B = _BV(CS21); // set prescaler of 8
TCNT2 = 0; // clear the timer2 count
TIFR2 = _BV(TOV2); // clear pending interrupts;
TIMSK2 = _BV(TOIE2) ; // enable the overflow interrupt
#endif
`
This is a noob code :) It will need a proper coding

Using a SG90 servo with this library and tinyGPS++, I still get jitter and erratic motor movement. As so as I add the gps begin, the motion of the motor no longer works correctly, mainly it moves back and forth and is not smooth. I take out the begin and the motor works fine. This is on a Elegoo UNO R3.

Any suggestions? I can add movie if necessary of motor action.

This library won't compile but:
'In fact after commenting out //typedef uint8_t boolean; from servoTimer2.h I do not have the problem'
