Interrupt driven ADC conversion (LL) (STM32F103)

I want to gather 4 ADC values from peripheral potentiometers using an STM32F103C8T6 (blue pill). I've setup ADC1 using MX Cube. Enabled ADC1_2 NVIC global interrupt.​Now I'm a bit clueless how to proceed.My idea is to start the ADC to do conversions....

I have written a simple application that takes characters from one UART and relays them to another. main is empty. Only two callbacks of HAL Rx and Tx are used.

Why, when transmitting at 115200 baud, after transmitting the Tx stop bit, the callback occurs after 8.5us? Does HAL add more delay? When using GPIO I measure the time on the scope from stop bit to stop bit I get 100us instead of 87us. Configuration ...

STM32H750 Type V - reading the Internal temperature sensor (ADC3)

Hello,I am trying to read the internal temperature sensor - but the value I get does not change at all (when I change the ambient temperature).I have the same raw value from ADC - 0xe41 -- >, which convert to -142.19 C (?!)I assume that something is ...

Using USART3 (VCOM on the NUCLEO-H723ZG board) an IDLE IRQ is generated after 512 bytes even if the host is transmitting more than 512 bytes. The IRQ is generated since bit[4] of register ISR is 1 and bit[4] of register CR1 is 1. From where "512" comes?

Problem occurs when octoSPI runs at 120Mhz (APS6408L-30B -BA RAM)

Hello everybody. I have a question. I am using the STM32L4p5g development board. First, I ran the APS6408L-30B RAM, which is connected to the oscoSPI peripheral, at 40Mhz, but I can't run this ram at 120Mhz, what could be the reason (I'm using the co...

FW Memory limitations.

Let's say that i am programming a FW that should read data from peripherals.How could I know what are my stack and heap and in general, my memory limitations?I am working with STM32U585 and searched in the reference manual, but could not find the ans...

The way to disable ADC completely?

I am using STM32G070 with CubeMX HAL code.  The system runs into STOP mode from time to time. I need turn off the ADC before it entering the STOP.  Here is my testing:If running the MCU without ADC by commenting out MX_ADC1_Init(), the system shows 3...
