Hello,I am implementing my own I2C drivers based on the LL drivers provided by stm32g031xxxx (STM is the only master) Transmission and Reception all work very well but I am trying to get away with some optimization by starting a I2C read from a slave...
Hello,I am programming STM32G491, while I need to use nRST as GPIO (MCO). I am using a code that you can see below. The problem is that when I am debugging a program, the debugger is disconected after HAL_FLASH_OB_Launch(); (this should reset MCU, am...
I have the following function to write data to the FM24CL64 memory: void FM24CLXX_WriteData(uint16_t memAddr, uint8_t *data, uint16_t size) { uint8_t memAddrData[2] = { (uint8_t)(memAddr >> 8), (uint8_t)(memAddr & 0xFF) }; HAL_StatusTypeDef s...
Hi,at the moment on the STM32U5G9 we have the SWD pins (SWDIO and SWCLK) set to DEBUG, but we would like to also use them as GPIO after programming. How do we switch them to GPIO at runtime? Thank you
Hi ,I am not sure but my development board STM32H750B-DK may have some issues and I need some help to find what it may be . As per the readme.txt (there is very less literature that I could find on this board) , I could dump the ext_mem boot bin int...
Hello.I tried to use an imu that was previously working using the spi2 port of the stm32f4 series with the spi4 port of the stm32h7 series, but I cannot communicate with it. (imu is using icm42688p.)Is it possible that I have made a mistake in my set...
Hi, I am configuring the ADC in single-channel continuous conversion mode using DMA. However, once I call HAL_ADC_Start_DMA(&hadc, &AD_RES, 1), the main loop stops executing, and the HAL_ADC_ConvCpltCallback() function is not triggered.I noticed that...
I have setup my NUCLEO-446RE as my transmitter and it works fine, But i am not able to read any data at the Receiver i.e. the blue pill. Main things i noted are: -> The MISO pin in any stm32F4 MCU has a function of "Alternate Function push pull" with...
While the Coarse calibration in RTCv2 is obsolete, in 'L1 and 'F2 it's the only method (and I know 'L1 is NRND, but it's still around and will be for years to come, if ST sticks to its commitment), and as long as it's mentioned in 'F4 it should be pr...
Hello everyone, I'm trying to sample some signals inside a timer ISR. I use all three ADC units of the mC (multiple channels in the first unit and 1 channel in each of the other two units) and I use software triggering and DMA transfer.This operation...
