Hi @roy_r_rankin, I tried the simulator and everything seems to be working fine. I'm still learning to use gpsim but I'm now able to move forward with the PIC16F1937. Thank you for the quick resolution!

Here are the functions that I'm using: 40-pin versions of PIC16F1937 and PIC16F1939 Features: Internal clock oscillator (8MHz) PORTS A,B,C,D,E EUSART EEPROM I2C ADC WDT (Watch Dog Timer) TIMER0, TIMER1, TIMER2 PWM INTERRUPTS * EUSART * TIMER0 * PORTB (Interrupt on change) Thanks
