2 ADC channels assigned to 1 MCU pin

I have designed a buck converter that uses the MCU to regulate its output voltage.I am using one pin for the voltage feedback that will be used to regulate the output.  However, because it has to read this pin very quickly, the sample period has been...

STM32H5 external loader

Hi, I need the project used to generate the external loader: MX25LM51245G_STM32H573I-DK.stldr. My custom board uses a STM32H563VIT6 and the same octo-spi flash from Macronix used in the STM32H573I-DK board. But with different gpios connections. So th...
