Schrodinger's Memory: In debug my STM32F407VG Discovery code is seeing zeros in an array loaded using DMA (which is working), but if I break and single step, the code suddenly see's the values. Super weird! I´m using STM32CubeIDE which was fully upda...
Hello,I am using STM32L011G4U7 and wants to get the adc value where it showed once and not it is giving 0 for the adc raw values. Also please let me know that in order to read the vcc that is 3.3 volts do I need to select VREFINT channel as well alon...
Edit: I've pretty much solved my problem. The issue of course was that I was setting the Complete flag in the first cycle. By changing: if(DAC_Complete){ swap_buffer(); DAC_Complete=0; }to:DAC_Complete=0; while(DAC_Complete){ swap_buffer(); }Things a...
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...
