ILI9341_T4 freezes at _waitUpdateAsyncComplete with tsandmann/freertos-teensy

Open birdboat00 opened this issue 1 year ago • 2 comments

Hello,

i was using this library with the freertos port by tsandmann (tsandmann/freertos-teensy).

The problem is, it freezes at https://github.com/vindar/ILI9341_T4/blob/d9bea487d0fa38fc52ffb2bf9e8efc7b827a1cbc/src/ILI9341Driver.h#L1433 for some time and then continues, even the SPI clock freezes (atleast the LED stops blinking).

I suspect the problem is the yield(); function. It works without FreeRTOS.

Is this a problem with the freertos port or with this display driver?

Best regards

Hi,

I never used freertos myself so I do not know what is going on but the ILI9341_T4 library make heavy use of interrupts so I am not really surprised that it does not work... Do you have a simple (complete) example/sketch that I could try to replicate the issue ?

Best,

Hey,

sorry for not answering for auch a long time. For my project I switch from FreeRTOS to ChibiOS and it works there, as it seems, properly.

I will prepare an example when I have time.

Sorry.

Best Regards Sebastian
