Hi,recently I switched from Arduino to Nucleo and now I wanted to play around with the H745ZI-Q and was following the step by step guide by st. Whenever I try to load a program to the mcu, only the demo blinky program is running. I have not found any...
HiI've configured two ADC 1 and ADC5 in independend mode with DMA and triggered by master compare from HRTIMER.I have two problemsFirst. When I have started two ADCs by HAL_ADC_Start_DMA one by onemy code freeze on debug after this, but when I set th...
Hi all, I'm having a trouble programming my F303K8 board on my Windows 10 laptop. It will power on (LD2), but it will not connect to the computer (LD1 blinking slow red). The laptop does not detect any device being plugged or unplugged, there is noth...
I try to use the SAI on the STM32F469 Discovery Board in DMA Double Buffer TX Mode. The Interrupt is working and the buffers too - but there are no data arriving at the SAI ADR Register. My init function is:HAL_DMAEx_MultiBufferStart(&hdma_sai1_a, ...
I can send CAN BUS TX Messages to a reader and I can see my data very well.But I can not get (receive) data from another CAN BUS Unit. (Doesn't read data)I do not know what is wrong with my code?Could you please help me about it?Thank you./* USER COD...
Hi,Can someone please help ?Has someone got USART Peripheral with DMA transfers working on the STM32H743ZI2 ?I have been trying to get DMA transfers to work on the H743. The DMA stalls after the very first DMA transfer and stays there itself.Searchin...
i have a program with a BIG lookup table. The program compiles fine except for if i reference the lookup table, then it quits with one error and doesn't tell me what the error is. How can i tell how big the compiled program - would be - with the look...
my interrupt code needs to make a decision based on a flag, which I stored in a global variable. However, the code wont compile as it doesn't recognise the variable inside the interrupt, but does everywhere else. Is this normal? If it is normal, is t...
Hi,I have used the STM32F1 and F4 series.I would like to know which line is advisable to medical device development ie. insulin pump, Blood glucose monitor.on the website i found that f1,f2 series can be used.Regards
Hello,I am working on a project and it would be very helpful if I could find a MCU with integrated 5V ADC. I know you can add a voltage divider for the 3.3V ADC but it won't work in my case for this project. Can anyone recommend me something? Thank y...
