Hello Everyone,I am working on stm32h723zg, and I want to obtaind the serial of the micro controller for the unique id:uint32_t unique_id[3];void read_serial_number(void) {// Unique ID registersunique_id[0] = HAL_GetUIDw0(); // Unique ID Register 1un...
Hello, thank you for reading this post, sincerely hope to help answer questions.The OSPI interface of STM32H735IGK6 is used to connect ISSI66WVO32M8DBLL to ISSI's PSRAM, which can read and write registers but cannot read and write memory. When config...
Hi,I am trying to communicate with the MPU-6500 from InvenSense and the STM32F405 micro controller in SPI.I managed to read the WHO AM I. And seems to respond well with its value of 0x70.The problem I have is when I want to read the accelerometer and...
@KDJEM.1 I have rebuild the above code in Keil and tried to load then i got below error. Could you please help me to start with the board.Thank you.
Hi, I am having issues using the STM32L431RBI6 to read a rotary encoder.The encoder has a 0-5V output on its 2 channels, and is working with my other STM32 setup (on a STM32L451CCU6).On the STM32L431RBI6, I am using TIM2 configured in Encoder mode, w...
I'm writing software on dual core CPU, On M4 core, I need to know is it support bit banding? I searched all documents from ST, but I didn't find clear answer, I found on M4 CPU, like STM32F series bit banding has supported, and on M7 single core CPU ...
Hi everyone, I'm developing a bootloader that works like this. I was inspired by the example: https://github.com/pramodk51/bootloader_for_stm32f4. I developed this initially on Nucleo F439ZI for the test phase and I managed to implement it with the ...
Bonjour, (in english below)J'ai travaillé sur un Nucleo-L053R8 de 2015 à 2019 (j'ai encore le Nucleo)Je reprends un travail analogue (réseau d'IoT basse énergie(LE) en milieu agricole, capteurs (certains nécessitant ADC), commandes, petits moteurs .....
