Arduino Robot #41

ghost commented 6 years ago

I am wondering, is it possible to use AltSoftSerial in any way on the official Arduino Robot? The OUTPUT_COMPARE_A_PIN is set to 5 on the AVR_ATmega32U4, and on the Arduino Robot it is connected to the buzzer, so can't access it in any normal way.

What could be solution to the problem?

Maybe edit AltSoftSerial_Boards.h to use the other timer?

Wasn't sure if I can switch the pin numbers directly, not to do any damage.

Hello, what's the number of the pin that you changed to?

JaroslavMalik commented 4 years ago

In AltSoftSerial_Boards.h :

// Arduino Leonardo & Yun (from Cristian Maglie) //

elif defined(ARDUINO_AVR_YUN) || defined(ARDUINO_AVR_LEONARDO) || defined(__AVR_ATmega32U4__)

define ALTSS_USE_TIMER1

define INPUT_CAPTURE_PIN 4 // receive

define OUTPUT_COMPARE_A_PIN 9 // transmit

define OUTPUT_COMPARE_B_PIN 10 // unusable PWM

define OUTPUT_COMPARE_C_PIN 11 // unusable PWM

define ALTSS_USE_TIMER3

define INPUT_CAPTURE_PIN 13 // receive

define OUTPUT_COMPARE_A_PIN 5 // transmit
