Hello, I'm trying communication between stm32G0 as I2C slave and a rapsberry pi 5 as master.on pi side, the call is: self.cpt = (self.cpt + 1) % 255 b = self.bus.read_i2c_block_data(42, self.cpt, 5); I've seen in several places on the web tha...
OverviewAt my job, I was recently tasked with handling ECC errors in both RAM and flash memory. Additionally, I needed to test the error handling by injecting ECC errors. Figuring out how to do this was a nightmare. I looked over AN5342 countless tim...
Hi,I am currently working on a Battery Management System (BMS) and an instrument cluster. I need your assistance with some issues I’m encountering while communicating between the BMS and a custom cluster board using CAN.We have two custom cluster boa...
I am trying to make a custom external loader for a qspi nor flash. the erase sector and write operation is success but after I tried the read operation the operation is fail the device is disconnected and showing this message I have tried to run a pr...
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...
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...
