Hi!I have two PWM signals coming into two MCU pins, that are two TIM4 channels. Channel 1 and Channel 2. I initialized both Channel 1 and Channel 2 to input capture mode on Both Edges and enabled the Capture/Compare Interrupt (Not in slave master mod...
Hello,I have a code snippet where I initialize PSP (stack pointer) to its very first location, and then manually fill the stack with some values as follows: pTask = (uint32_t *)TASK1_STACK_START; //Stack Start location for Task1*pTask = (uint32_t) S...
Connected to STM32F411CE I know this post is not fully related to STM32 but I am posting here as this forum is somewhat active so I can get some help. SIMCOM forums are pretty much dead. I am interfacing sim7080 with stm32, but for this test I am bas...
Hello,I am working on a project to design an IO and motion controller board using STM32H755 mcu. Could you please review the attached basic schematic design for the mcu to avoid any design related issues that may arise later. +3.3V power is coming fr...
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...
