I am using TIM1 for medium-frequency PWM and TIM8 for high speed ADC sampling with a STM32F765VIT6. TIM8 triggers ADC1, ADC2, and ADC3 where DMA streams collect the data. The frequency of TIM8 is a multiple of TIM1 so once it is started it will remai...

I'm trying to define a region of RAM for storing debug information that can persist following a reset (DEBUG_RAM). I'd like to put variables in a section (.debug_ram) that are stored in the DEBUG_RAM memory such its usage properly displays in the Bui...

I'm modifying some code to start using double buffered DMA. Everything in the code currently uses the HAL so I'd like to continue this but it seems ill suited for using double buffering with the ADCs.This code gets me close: HAL_ADC_Start_DM...

I have a project that is using DMA channels to transfer ADC values to DTCM. The values seem to be getting to the memory correctly but I was confused by Figure 1 of the datasheet which shows the ADC/DMA/SRAM on the AHB but the DTCM on a bus that appea...

I started a new job where everyone is using VSCode so I'm attempting to be a good citizen and use it to. Before this I used STM32CubeIDE. Unfortunately nobody is here to help me today and I'm hoping to work over the holidays. I can build in VSCode fo...

Using CH5 or CH6 of TIM1 to trigger TIM8 is what I'm looking at, but I only want to do it once and after that I want TIM8 to run freely.If I use TIM1 to trigger TIM8 once, it seems I'd need to then turn off TIM8 to unconfigure the trigger?

NOLOAD seems to have worked!With my debug variable in the DEBUG_RAM region I'm now getting a 6kB bin file!Thank you so much for this!

Thanks for writing me! I actually recognize your name from when I used to write here at my last job and I remember you being a really knowledgeable and helpful guy.In my main.c I am not initializing the debug_ram_test variable so I wouldn't have expe...

The MCU only has 2MB of Flash so a 393MB bin file doesn't make sense. If I try to load the file in STM32CubeProgrammer it says that it's too big.If I simply remove __attribute__((section(".debug_ram"))) from debug_ram_test in main.c, the bin file red...

Honestly my HAL_ADC_MspInit() called by HAL_ADC_Init() looks very different from yours, but it's also from a common library in my company that is supposed to be generalized. The one in your picture assumes you're always using DMA1_Stream1 for any ADC...
