how use the second UART of the PIC16F1947 - jccortes - 2015-09-12

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

Hi , I attached the project in ZIP format , I tried to modify the file you mentioned but does not work me , thanks for your time

Here comes a new devices_PIC16F.inc with support for uart2 with PIC16F1947.

thank you very much, sorry for the delay in answering, I will try and notify you if it works properly

regards

Hi Mikael, i tried to use the second uart with the new file of devices PIC16F.inc, but not work, I test every baud rate possible, but not work.
Any suggestion??.
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

RE: how use the second UART of the PIC16F1947 - Mikael Gustavsson - 2016-02-04

Zip and post the project.

RE: how use the second UART of the PIC16F1947 - jccortes - 2016-02-14

This is the project, thanks

Hi Mikael, any news about this post??? thanks

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

RE: how use the second UART of the PIC16F1947 - jccortes - 2016-03-12

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

RE: how use the second UART of the PIC16F1947 - jccortes - 2016-03-12

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.

RE: how use the second UART of the PIC16F1947 - jccortes - 2016-03-12

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

Great! Feel free to post the code. It may be useful for other people.

RE: how use the second UART of the PIC16F1947 - jccortes - 2016-03-23

yes of course, here i put the code.

RE: how use the second UART of the PIC16F1947 - mrjaco - 2019-12-24

Here comes a new devices_PIC16F.inc with support for uart2 with PIC16F1947.
