Resolved! UCPD sink on STM32G4
Is it possible to implement UCPD sink on a stm32G4 without RTOS. What all does that entail? What are the pros and cons?

constant square wave on USART2_TX (PA2) after a power cycle (brown-out)
We get a constant square wave on USART2_TX (PA2) on some of our STM32L451CEU6TR products. This seems to happen sometimes after a power cycle (brown-out). The square wave is a around 32kHz. As mentioned, this only happens on a few of our units, and af...
Resolved! STM32H73x: HSE / LSE oscillator levels with passive crystals
Heyho,there's lots of info in the datasheets and the AN2867 about the specs of the HSE / LSE oscillators with passive crystals...But I'd like to have some "measurable" *** specs, so that I can compare a real life custom board, which means:voltage lev...
Resolved! Power consumption does not fit with datasheet information
Hi,I'm running STM32C011F4U6TR using the LSI (32KHz) in a infinite loop.Here's the current consumption I see from the STM32CubeMonitor-Power softwareI expect to see around 80uA flat as datasheet shows at page 39What could be the reason for the 170uA ...
Resolved! USB Issue when porting from STM32F072 to STM32L072
Hi all,I'm porting a project from a F072 (Nulceo-F072) to a custom PCB with a STM32L072.The board is going well, except when I try to use the USB (CDC mode).When I plug it into my PC, the OS can see it - Bus 006 Device 072: ID 0483:5740 STMic...
STM32H7 ADC faster than expected
Hello,Using a STM32H743ZI - rev. V.I'm using ADC3 to convert 4 channels in regular conversion mode, with a 2.5Tcy sampling time, 10 bits, sync clock /2.The measured conversion time is quicker than expected so I'm suspecting something wrong...CPU cloc...
Clock Configuration, Timer and LED
I am still new to STM and I am trying to perform a task on timer, I have written my code to configure the clock the my desired frequency and also I have written the code to set up my timer but when I downloaded the code to my board (stm32g070rb), my ...
Efficient Method to Generate a Sine Wave Using DMA and TIM1
Hi What is the most efficient method in program logic to generate a sine wave using an H-bridge with an advanced timer?I am using TIM1 on an STM32 microcontroller, which has two channels (Channel 1 and Channel 2) and complementary outputs. For genera...
Resolved! STM32H7 code execution time question
Hello All,I needed a very fast vector addition routine for the H7 so I wrote it in assembly. However, I discovered that very small changes in the code caused huge differences in execution time. Both of the following functions add a 16-bit vector to a...
