STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
Hello,I'm just a beginner that tryes to migrate from the arduino world to ST and before I start the dev jorney I'd like to hand on to a debbuging method that requiers as little hardware and sofware setup as possible while still having the logging and...
I'm trying to operate the USART in DMA tx mode on the STM32G0. I've configured the DMA mux to route the USART1TX dma request to channel 2. I have configured channel 2 to enable TC and TE interrupts, enabled MINC, and set PSIZE & MSIZE as byte. The nu...
HAL_StatusTypeDef HAL_RTC_DeInit(RTC_HandleTypeDef *hrtc) function returns HAL_ERROR because RTC_EnterInitMode(hrtc) returns HAL_TIMEOUT. When checked in community, I can see solutions as to call HAL_PWR_EnableBkUpAccess(); before setting RTC functio...
