Send data over SPI instead of serial wire debug
I am developing some trackers for personal use in VR and have found an excellent solution that meets my needs using the STM32CubeIDE environment and some boards. I create and test the files, but I realize that debugging over serial communication is n...
Resolved! STM32L496 Resetting CAN TEC/REC Counters
I have a system in which the power source to the CAN transceiver interfaced to the on-chip CAN peripheral is common between multiple MCU's vis-a-vis a connector. I have experienced issues wherein if the connection is broken and then re-connected betw...
Resolved! STM32G474RE HRTIM ADC Injected Conversions not triggered
Hi there,I am configuring HRTIM TIMD to generate PWM which works as expected, roughly following the Synchronous Buck Converter example for the DPOW1 eval board (my target is the nucleo64).I use LL API calls instead of HAL calls for my project. I ha...
send AT commands via stm32l011
hello everyone, I have a problem, I have a custom PCB with an STM32L011, I have a sim800l module connected, I send the AT commands via LPUART1 and I want the response on UART2, but as an answer I got AAAAAAAAAAA and after a while Call Ready,Call Read...
Problems clearing USB interrupt bits from STM32F411 GINTSTS register
Trying to work with the STM32F411 USB OTG peripheral and compiling with Segger Embedded Studio, I'm having trouble clearing out the USB interrupts.The USB peripheral has IRQ bits that are write-1 to clear. As can be seen in the image below, the brea...

Resolved! Difficulty configuring TIM16 for simple PWM output on STM32G483
I am working on an STM32G483VET6 in my own hardware. I am trying to use TIM16 CH1 (pin PE0) to generate a PWM signal which drives a sounder. I believe that in early tests I verified that it was working but I was probably messing around manually with ...
