Hello everyone, I am implementing a DMX interface on a STM32G071K8. You will find information about DMX here: https://www.thedmxwiki.com/dmx_basics/dmx_timingAn UART interface is used to get DMX data. • I am used to use the Frame Error detection ...
Hello, I am working on a project with an STM32f446 and I need to disable all interrupts while executing a specific critical function. I put in my code the following lines : __disable_irq(); Critical_function(); __enable_irq();But I still...
Thanks for this answer, I have bypassed the issue using another IO and a timer to detect the breack signal. I will have a look at the code on your link. I had checked my previous code in step by step, using direct register access, but I could not fin...
Does the DMA still work if interrupt are disable with __disable_irq ? My critical function must not be interrupted but I have an assynchrone input on UART which is manage with DMA. But it seems that I do not get the full uart frame if the reception o...
Thanks for your quick answer, I am using Keil RTX os. And I am not sure about privileged mode, I need to check that, I did not change this paramters on purpose at least. Is there a quick way to know (register reading in debug or...) if I am or not in...
