how use the second UART of the PIC16F1947
#1
Hi, i tried use the second UART of the PIC16F1947 for the ds30loader, but i cant do it, because a error on the compilation appears, where tell me, that PIC no have second UART, i am sure of that PIC have second UART because I use it (the second UART) with no problems.

the error is:  UART.INC 71 : ERROR: (UART2 specified for a device that only has uart1)

I configure the parameters of the communication, baud rate, device, FOSC, configuration bits, etc etc, and I used it with no problems in another chips, PIC16F1933,PIC16F1936,PIC16F1938

I missing something??

is problem with the version free??


Thanks.

Hi,
Please zip and post the entire boot loader project. Or modify the devices inc file yourself.
Thanks

the process of compiling finish all good, so, i dont have any error in that part. the process of burn the PIC it's ok, the UART 2 it's ok, i test a simple program and work the uart 2

Hi,
You have not set the configuration bits. You need to do that.

Hi, configuration bits placed them from the environment MPLAB , I have always done and had not given me problems until now.

could you give me an example of how they should go, please, thanks

hello, I recompiled the project from the template, mark an error in the Ansela in UART2 that there PIC ADC, I think maybe that's the problem.

worked, was the ANSEL, in AD pins UART2 two channels, configured as digital inputs and outputs were and run
