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:--------------------...
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...
I'm using STM32F767 and external flash is interfaced on QUADSPI, I've referred STM32746G-Discovery code for QSPI without DMA and its working fine. I want to implement QSPI using DMA, STM32F767 supports QSPI over DMA on channel 3 and stream 7 so did c...
Hello everyone,I'm having problems with a STM32L010K8 in stop mode.I'm trying to use the low power timer clocked by the LSI and having it to wake up the device from stop mode once the timer reaches ARR value.I configured the EXTI event line 29 and de...
Can anyone share USB Host CDC VCP Example code for STM32F429 or STM32F469?
