Hello, I'm using stm32f103c8t6 board and trying to get simple voltage divider readings. I'm also using multimeter to measure voltage and well I'm getting 0.2 sometimes 0.4 V error. Is this normal? I really need precision, 0.2 or 0,4 volts are reall...
Hello everyone, I am using STM32F767ZI which in the reference manual has ITCM, DTCM, SRAM1 and SRAM2 but in the linker script it is just RAM so I am trying to change it from: MEMORY{ RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 512K FLASH (rx) : ORI...
Good morning to all,I was wanting to save data in the non volatile memory of my STM32H745i-Disk with the STM32H745XL micro.It is only to save the following structure to read it every time the microcontroller is turned on and modify it from time to ti...
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 all,I am pretty new to ST so bear with me.The controller is reading in voltage values into the ADC and sending to PC over serial withCDC_Transmit_FS((uint8_t*), buffer, buffer_length)I'm getting the data stream, but the values as read in python fo...
Hi,Can all selected channel's sampling in each SAR ADC(0, 1, 2) be trigged by the same timer with the same settings so that their sample can be synchronized ?Thanks
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...
