DSPIC33EP512GP502 -- PCD v5.115 UART2 Enabling
PostPosted: Fri May 03, 2024 3:01 am     Reply with quote
Hi, in order to use and enable uart2 on dspic33 is it sufficient:

Code:

#define UART_2_TX           PIN_B11                                              // DsPIC UART2 TX
#define UART_2_RX           PIN_B12                                              // DsPIC UART2 RX
#PIN_SELECT U2TX=UART_2_TX
#PIN_SELECT U2RX=UART_2_RX
#use rs232(uart2,baud=115200,PARITY=N, BITS=8, ERRORS, RECEIVE_BUFFER=100, stream=SPECTRUM)


Or I also need to set to 1 UARTEN bit 15 in register U2MODE address 0x0230 ?

Regards,

Marco

Totally sufficient, _BUT_, you must have an 'enable_interrupts(GLOBAL)',
in your code, since you are relying on an interrupt to handle the receive
buffer.
