Hey together, I have a question regarding changing the clock while running in XiP mode. Upfront everything works so far very well. On our STM32H750 we have a very simple bootloader. This bootloader configures the QSPI and the STM32H7 to run the appli...
Hi everyone, I’m working with a custom made STM32F446ZET6 board that otherwise functions perfectly (all peripherals, flash programming, etc. work fine). The only thing that doesn’t is the ROM bootloader. I can’t get USB DFU or UART boot to respond no...
Hi,I'm exploring using UART idle interrupt on RX to signal to my application that data has arrived.I currently push data into a tx queue then start transmission. I rely on uart tx ISRs to check if there is any more data to send, then load up a DMA tr...
I am trying to use one STM32M4 as TX, and another STM32M4 as RX,but RX can't receive the correct i2s data that TX transmits.TX transmits 16bits data by HAL_I2S_Transmit_IT(&hi2s2, i2s_dummy_buffer, 16);RX receives 16bits data by HAL_I2S_Receive_DMA(&...
Hello,In AN5967, it says:When VBAT is connected (VBAT = 3.0V)? will the oscillator (RTC) stop running if VDDA18AON is not present?There are several conflicts between the various documents... Can someone at STM update the docs?AN5967, RM6486, UM3300...
I am unable to control GPIO output pins with the H5 GPDMA. I am able to control GPIO with the F103 using this project...https://github.com/mnemocron/STM32_PatternDriver...where the DMA is much simpler. Section 3.7 of AN5593 (How to use the GPDMA fo...
So new problem while trying to bypass non functioning SWD...Using a working NUCLEO_H723 I can use the STM32CubeProgrammer to access it via STLINK (internal and external) as well as via USB DFU after reset with BOOT0 high.From my reading of AN2606, on...
Here is the code: void DMA_Init_SPI2(void *rxBuffer, void *txBuffer, uint16_t rxSIZE, uint16_t txSIZE) { RCC->AHB1ENR |= RCC_AHB1ENR_DMA1EN | RCC_AHB1ENR_DMAMUX1EN; // DMA1 Channel 1 для SPI2_RX (Peripheral-to-Memory) DMA1_Channel...
I have an STM32G431 doing FOC on a little gimbal motor, but am getting strange noise on the current sense ADC when it's being triggered by TIM3. It shows up as random spikes, which values always end up being dividable by 8. Weird thing is, if I have ...
Hi all, I have an STM32L071VBT6 and want to test the UART functionality. I configured UART4 RX and TX and physically connected them to do a loopback test. I define 2 arrays to start with /* USER CODE BEGIN PV */ uint8_t Send_buffer[] = "Gateway tes...
