STM32 TIM CC IRQ and USART RXNE IRQ

Hi everyone,I’m working on an STM32C0 setup where TIM1 CH1 (Pin A) and UART RX (Pin B) are physically shorted together, and I’ve encountered some unexpected interrupt behavior. Specifically, the UART RXNE interrupt always triggers before the TIM1 Cap...

Resolved! FATFS Failure with FreeRTOS

I am using the STM32H7B3I-DK for my project. I am trying to integrate uSD card usage with a touchgfx program. I have gotten a simple write to a file working on a non rtos project; however, when I use it in my project with RTOS I keep getting a hard f...

Resolved! SDMMC FATFS mount Hardfault

I have followed How to create a file system on a SD card using STM32CubeIDE the best I can using the STM32H7B3I-DK. With this board I do not see the DMA tab under SDMMC1, so I have skipped that. I am failing the f_mount(). I am using a touchGFX proje...

STM32H743 SPI DMA delay

Hello.I have a TIM3 configured to generate a PWM signal with frequency 1 MHz and duration 200 ns using CC1 channel. TIM3 also generates a DMA request on CC1.DMA1 is configured to transfer value 0xFFFF from AXI SRAM to SPI2_TXDR register, triggering t...

LPUART consumes extra 3mA while STOP2 mode

I'm using STM32WB55. The reference example is BLE_p2pServer with custom modifications. The power consumption of STOP2 mode ( by enabling CFG_LPM_SUPPORTED ) is around 6mA (board level), and it will be around 9mA after LPUART is enabled with RCC_LPUAR...
