How is the flash memory of my STM32L4S5VIT organized?
according to the reference manual. This can be organized in 1 bank of 2mb or in several banks. I have created a default project with the stm32cubeide and I would like to know in which mode the flash memory is configured by default. I can't figure out...
Overrun error in LPUART when using Hardware Flow Control
We are encountering this while using Low Power UART on STM32L412KB microcontroller. We are working on a battery-powered product that has two on board SoCs. One of them is STM32 and the other is Nordic. The two socs communicate with each other over a ...
Resolved! G473 - PA10 I2C. Docs issue?
I have been troubleshooting a I2C device for longer than I'd like to admit. Today I attempted to configure with CUBE, and I think I've found the pin I'm using may not be compatible.PA10. Can it be used for SDA2? I thought it could based on the AF tab...
