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...
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...
I have a routine that self-calibrates a system and returns two uint16_t values that I need to write into non-volatile memory and read at bootup. The values will only be written once during production so write time isn't important. And it needs to be...
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:--------------------...
Hello all,I recently purchased the STM32F469i Discovery Board, and have loaded the compiled demo binary from the ST website onto the board. It loads properly, but now I want to see how the software works. Is there any source code for the demo firmwar...
