PIC32MZ2048EFM144 UART problem (incorrect remap pins) (SOLVED)

Post by Lagoda »

Hello,

I would like to ask for help.
If I set the UART to "Channel 6" in the attached program, it can not receive the characters. If I set channel of UART to "Software", it works perfectly. The external clock of the MCU is 14.7456 MHz.
I also attached the clock settings.

( I tested the UART transmitting direction also with these settings, it worked in both cases.)

Best Regards,

Lagoda

:D I found the cause of the mistake!

The Rx input of the UART6 I set in the Flowcode to the RD5 pin, but in fact the RB6 was activating.
When I checked the content of the U6RXR register I found 0x05 instead of 0x06.
I corrected the value to 0x06 in source C and then it worked.
Unfortunately I do not know where and how storing datas of Mapping Table in Flowcode, so that I can correct it.
If you think I'm happy to help you check the related values, if you tell me the way, because I want to use the revised version as soon as possible.

I started a project with this MCU and would like to use Flowcode for development.
In the project I need to use 6 UART, 6 SPI, 2 PWM and 3 A / D channels.
I think I will have more questions. :wink:

Best Regards,

Lagoda

Hi Lagonda

I have more or less the same CPU. PIC32MZ2048EFG100.

Herre are my measurements .....
viewtopic.php?f=7&t=19541

A little tip to the IRQ. Take a look at the compieler option of Micromips and MIPS32

Hi Stefan,

Thank you very much for the informations.
The knowledge that you share will be useful to me as well.
I'm glad you work with this MCU family and there I'm not alone on the forum with the problems. :)

I'm begining of the work , now testing the peripherals.

Best Regards,
Lagoda

Hi Lagoda,

Right I have found a fixed the incorrect remap pins. It effected a lot of devices so it's a nice find.

Simply extract the contents of the attached archive into your "Flowcode 7/FCD/PIC32" folder and restart Flowcode to load the changes.

Hi Ben,

Super! :D

I tried just a few pins, but they worked.

Thank you very much.
