Static Constant Variable Allocated as RAM when used by HAL I2C functions STM32CubeIDE

Hi, I am working on a project where I have a 4096 byte data array that I will be passing to another component via I2C. This array is a constant, so I declared it as follows in order to have it live in flash memory rather than RAM:static const uint8_t...

STM32 with RJ45

Using STM32CubeIDE in order to program SPI1 on STM32U585AII6Q with SW NSS. The relevant pins are not initialized and PinOut seems weird.

Trying to configure SPI1 with SW NSS on STM32U585AII6Q with STM32CubeIDE.While generating the code, the relevant 4 pins are not initialized.The PinOut looks like that. This grey shade seems suspicious to me.Below, MX_SPI1_Init() and MX_GPIO_Init()sta...

Resolved! Nucleo-STM32f030 ADC setup Issues This code only works when I'm debugging step by step. Otherwise, it always sends ADEN low again, which should not happen!!

This code only works when I'm debugging step by step. Otherwise, it always sends ADEN low again, which should not happen!! (Correct sequence: ADEN goes high then ADRDY goes high and both stay high...) (Note both ADEN and ADRDY are low before line 54 ...
