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...
Hi,I'm porting a C++ application to a STM32, using CubeIDE. The application uses cin/cout, for which I implemented the __io_getchar() and __io_putchar() functions used by _read()/_write() from syscalls.c, redirecting the input/output to UART. This wo...
In my code, I write many casting from char* to uint64_t*. Someone success, and someone get failure. I thought I used the unallocated memory, but I rewrote by casting to uint32_t, and then no error happened. Is this normal?My code:--------------------...
