Auto-polling mode with octal memories is not functional.

Hello everyone,I made a custom board for our design, a STM32L4R9VI and an ospi memory MX25UM51245G are integrated on this board. There is a MX25LM51245G on STM32L4R9I-disco board, but it is not in stock, so I chose this 1.8V version MX25UM51245G. The...

Would you tell me the condition(Hi/Low/Hiz/PullHigh/PullLow) of all ports of STM32G474 MCU chip when it gets boot mode with boo0 pin of high?

I'm building a new custom PCB with the MCU(STM32G4) chip and needs to get it updated with a new Firmware through UART by main computer. then I HAVE TO CARE all MCU pins so as NOT to make bad effects on other LSI during boot mode. I need to know all t...

Resolved! Trying to find best and most reliable way when using the STM32 timers to change the timebase 'on the fly'.

Hi, I've recently retired from being an electronics design engineer for over 40 years. I wanted to have some fun playing around with micros to do some basic control. I have both the Nucleo-F030R8 and STM32F4 Discovery evaluation boards and have bee...
