What is the best way to debug both ends of a communications link?

Windows 10, CubeMXIDE 1.12.0Mixed C/C++, STM32L562 processor on custom board. using STLINK V2 and V3 debugging.Common software installed as links, configuration file and main.c are really the only unique files that I provide. Configuration file is ...

trigger ADC every "X" IRQs from TIM

Hi, I'm building an LLC converter using STM32F301C8. The converter consists of MOSFET half-bridge. The output voltage is controlled by changing the switching frequency with a constant duty cycle of 50%. I use TIM2 for PWM and adjust the frequency usi...

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...
