I'm using an STM32F429. I have setup a timer to capture rising edges on CH1 and a DMA to store the captured values into a circular buffer.How can I temporarily stop the DMA from placing new values into the buffer while I'm reading values from the buf...

Hi, I used to write bytes at 0 in flash bytes that are erased (0xFF) but this is no more possible in the flash of the STM32U585 because of ECC that protects 16 bytes chunks I suppose.However now I have an 8K sector programmed with some data except f...

Hello,I think that I found an issue in the HAL code generated by CubeMx 6.6.1 with STM32L4.I2C HAL in file stm32l4xx_hal_i2c.c line 6855 there is an infinite loop : while (__HAL_I2C_GET_FLAG(hi2c, I2C_FLAG_STOPF) == RESET) { /* Check for...
Hi, on my board i`m running bootloader in internal flash of stm32h750 together with 2 QSPI NOR chips that store main program.Bootloader starts and jumps to main program in QSPI, howeverit get`s tricky when this function is called:SystemClock_Config()...
I am using the UART of STM32H747,with DMA transfering data. There is a Note in the reference manual about DMA_SxCR register:And in the Errata sheet of STM32H743, it says:What does a concurrent transfer mean? Will the DMA channel transfering UART data...
I have a 32f769i-disco board that has limited pins exposed on an arduino connector. I need what is termed a "capture compare timer" and I'm not sure I understand it. the capture compare time was used on the arduino version of this code.1) I've setu...
I realise that with ADC timer triggered DMA of 32 samples, you can set the timer precisely, but not the ADC per sample clock, so the samples get bunched up or stretched in the frame. The number of clocks per sample is limited, adjusting the APB2 clo...
The data sheet for this family of parts mentions a Quad-SPI, butaccording to the datasheet the QFPN32 package does not appear to have QUADSPI_BK1_IO0 exposed to a pin (see picture). The Quad-SPI configuration in 1x/2x/4x IO mode all appear to requir...
