hi guys. do i need to change these line of code if i want to use FreeRTOS in ATMega16. by default these code is used in FreeRTOS ATMega128 and ATMega64. i got the code from FreeRTOS ATMega128 CodevisionAVR example (), and the code is located in FreeRTOSV5.2.0\Source\portable\CodeVisionAVR\AVR\port.c
Code:
/* Hardware constants for Timer1. */
#if (defined _CHIP_ATMEGA128_) | (defined _CHIP_ATMEGA64_)
/* ATmega64, ATmega128 chips, Timer 1 runs in Mode 4 */
#define portCLEAR_COUNTER_ON_MATCH ( ( unsigned portCHAR ) 0x08 ) // WGM13=0 WGM12=1
#define portPRESCALE_64 ( ( unsigned portCHAR ) 0x03 )
#define portCLOCK_PRESCALER ( ( unsigned portLONG ) 64 )
#define portCOMPARE_MATCH_A_INTERRUPT_ENABLE ( ( unsigned portCHAR ) 0x10 )
#else
#error please modify Timer1 hardware constants to suit your chip
#endif
