STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello everyone. I am trying to write a bootloader with STM32H750IBT6 and mt25ql512. I am trying to adapt the ExtMem_Boot example of STM32H750-DK to STM32H750IBT6 by modifying it, but I can't succeed. It doesn't make sense why STM32H750IBT6 does not w...
Hi,I am working on a project that store the Configuration data of one device, It needs to be stored in specific sectionstatic unsigned char myBuffer[4] __attribute__((section (".m_data_20000000"))) { 11, 22, 33, 44};with this command I'm able to stor...
Hello,I am using an STM32F746VGT6 with a LAN8742A PHY to implement a basic TCP server using freeRTOS + LwIP for text communications. I've attached the code below: #include "bti_tcpecho.h" #define TCP_SERVER_TASK_PRIORITY 10 BaseType_t bti_tcp_serv...
Have a problem with write Scatter-Loading Description File for STM32H743 (arm keil).I need to map SDRAM memory.Regular I do it like:RW_RAM1 0xD0000000 0x00800000 { ; fmc bank 2 *(SDRAM) }On all other MCU's it's work perfect, but not for stm32H7. It'...
Hello, I am looking for a way to set up DMA to transfer from peripheral to circular buffer triggered from Timer I hoped I could set it up just like it is described here, just change the source:It samples data as expected but only once, it does not re...
Dear All,I've been using MCU/DSP-related products for over 10+ years, but I've always had some confusion about clock multipliers and dividers. I'd like to ask for everyone's opinion on this topic.As shown as below figure (it's the clock configuration...
I'm working on a STM32G473RCT6 CPU with 256K Flash in dualbank mode.looking for information on addressing the 2 banks of flash in CPUs with less than 512K I came across this post which clarifies the issue:https://community.st.com/t5/stm32-mcus-produc...
Hi I am using below controller in one of our designSTM32G474CET3 i would like to know minimum external clock frequency on which my microcontroller works. Also my requirement includes 1 SPI, 1 I2C and 4 ADC input sensing. I would need very minimum ext...
Usually, fresh (no firmware) STM32 MCUs will be in bootloader mode by default without needing to toggle the boot and reset pins. In such cases, we proceed directly with the firmware update procedure using the default slave address (0x5d).However, we...
Dear Community,I am currently facing this issue where my STM32 Black Pill F411CE suddenly went into hard fault during runtime. The MCU was permanently gone and was not able to be re-programmed, and four others that I connected to the same hardware we...
