Dear ST Community,I'm hoping to get some help identifying the manufacturer, year, and month of manufacturing for an STM32f103c8t6 microcontroller I have. The part number on the chip is 991KA 93 MYS A03.I've searched the code online and in the datashe...
Hello All, I am trying to implement baremetal implementation for Continous Conversion Mode. I have wrote the below code. I am expecting that the ADC will read A0-B0-A1-B0 in this sequence. However the code is only reading A0 and not any other pins....
Hey guys.I'm trying to build a custom Pcb that doesn't include the onboard st-link and be able to program it though the STDC14 connector.I found some schematics about the nucleo H7A3ZI-Q board, but i was confused about a couple of things.1) The STDC1...
Hi,I'm using the internal EEPROM bank 0 for the STM32L073 chip located at 0x08080000 (as per the user manual). After writing my data (less than 1K; and bank 0 has 3K capacity) and trying to enter into debug mode, system refuses to do so:(BTW: such l...
Hi,Master:platform: STM32G070CBkeil ide: arm Compiler:version 5 (c99 mode)Question: #pragma pack(8) typedef struct{ uint32_t a; uint8_t b; uint32_t c; uint32_t d; uint32_t e; } x_t; #pragma pack() x_t a[10] = {0}; int sz = siz...
Hi, STM Experts,Recently, we are investigating if STM-H5 MCU with I3C SDR support could meet our system requirement. We now have a following question, and hope get support from you.In our system, there will be not only I3C devices but also I2C legacy...
Hello everyone!Ran into some issues writing float data to the UART. I know with Nordic, there was some weird workaround that had to be used to convert it that looked something like this: NRF_LOG_INFO("MLX90393 X = " NRF_LOG_FLOAT_MARKER "\r", NRF_LO...
Hi,I am using STM32H755ZI for a project and i want to provide a firmware update feature. I will only have one USB port in the end product, so i can't use ST LINK. When i try to upload using DFU, i need to pull my BOOT0 pin high such that the bootload...
using the STM32H753VIT6, I like to monitor the on-chip temperature sensor. The environmental temperature can become about 50 degrees Celsius, and the board is housed is a small plastic (DIN-rail) enclosure. This enclosure is fitted in a metal cabinet...
Hi Peter,Greetings.@Peter BENSCH Could you kindly confirm whether the Analog Mux/Demux IC M74HC4052RM13TR can be interfaced with 3.3V STM32G4 MCU?Also, is there any suitable FFF equivalent part that could replace existing Mux/Demux IC M74HC4052RM13TR...
