Hello,I'm working with STM32H745ZITX on a dual-core setup. I configured USART3 on the CM7 core. The communication flow is:TX: Using HAL_UART_Transmit (polling)RX: Using HAL_UART_Receive_ITThe first message reception works correctly. The HAL_UART_RxCp...
Hello everyone,in my current project, I'm working with a Nucleo H743ZI2 (with an STMH743ZIT6). My goal is to read audio data from MEMS microphones using DMA and DFSDM filters. The ultimate aim is to build an 8-microphone array, but for the first ste...

Hi everyone,I’m trying to chain two timers on an STM32U585 so that:TIM1 generates a PWM on PA8 at 125 Hz (2 ms high / 6 ms low).TIM8 acts as a 20 µs sampler: it should reset and start counting at the falling edge of the TIM1 PWM, then fire its Update...
I am using STM32G030 for my project when using version Z (REV_ID 0x1001) the functions in the firmware run as required. But when using the same firmware, the above hardware loads version Y (REV_ID 0x1003) the functions run incorrectly, especially the...
Hello everyone, I am using a custom board with STM32H750 and I am trying to develop a file system with FILEX. The file system' s media is a uSD card with 10 MB/s baudrate which is communicating with the micro thanks to the SDMMC peripheral. The SDMMC...
I am currently using the STM32N657 to drive an 800x480 pixel display with 24-bit color. The problem that I am running into is the buffer that I need uses 1.1MB (800*480*3 = 1.152MB). Using just FSBL, I am limited to 511KB of SRAM. I know that this ch...
I am currently using the v1.6.1 of STM32CubeIDE and a STM32G473 MCU.I have implemented an I2C bus and have noticed a major bug with the I2C_WaitOnFlagUntilTimeout functions. There is this condition:if (((HAL_GetTick() - Tickstart) > Timeout) || (Time...
I have been testing the USBPD firmware examples SNK1M1_Sink and DRP1M1_DRP (the board is the NUCLEO-G474RE). When a PD source is connected to the board running either example and then the board is reset, it will then renegotiate the contract with the...
Hello everyone, I encountered a problem while using the STM32H750 MCU. The hardware environment is STM32H750 + USB3300, which is used as a USB HOST HS to collect camera data. An LTDC interface is used to connect a TFT-LCD for display. An external SDR...
