MCUXpresso config tool no working fine

PedroBecerra — Sun, 30 Apr 2023 13:08:18 GMT

I'm tryibg to use MCUXPRESSO config tool to configure some peripherals on LCP55S16.

I'm so sad getting problems.

1. I need a uart with TX inverted. The config tool do not allow to do that. I should do that writing directly to the proper register.

2. I want this uart to use DMA. I'm not able to get working.

3. I need an SPI interface to read an SD card. I get a Hardware fault inside SPI_MasterTransferBlocking() function.

4. I need a PWM to output different values writed from DMA. I'm not able to get it working. There is no possibilty of use DMA with PWM in the config tool.

Any one has a solution for any problem I have?

I recommend to you to take a time to read the following links and adapt them to your MCU

Thanks a lot for your answers. I'll Have a look to all the links you provide.

But as I said, all your answers point to aplication notes. There is none telling how to do it with the configuration tool. This is my compliant. Configuration tool does not work fine.

Anyway I am very grateful for your help.
