Hello All,Greetings,This post is regarding USB in STM32H7 series. In my project STM32H743 is used as custom HID. My board is used in 5 different configurations(5 PID/Device). I am using firmware package of STM32Cube_FW_H7_V1.10.0 as a reference driv...
Hi ST Community,Does anyone know how the HSICAL48 value gets loaded into RCC_CRRCR? The RM says "These bits are initialized at startup with the factory-programmed HSI48 calibration trim value", so I assume the trim value is stored somewhere in system...
I am trying to enable USB host work. I added HAL_PWREx_EnableUSBVoltageDetector(); into void MX_USB_HOST_Init(void). and followed git examples for H7. But could not make it work(( now green VBUS led is highBut my device is not connected. When I turn...
Is it possible to implement UCPD sink on a stm32G4 without RTOS. What all does that entail? What are the pros and cons?
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...
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...
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 ...
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...
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...
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 ...
