I'm the hardware guy on a 32F413 project where we have a lot of impulse noise nearby on the PCB. Because of this I've been on a campaign to make certain that all microcontroller I/O pins are equipped with pull-up or pull-down resistors.The project h...
I am facing an issue with my custom-made STM32F4x minimum system board. I am experiencing unstable connections with the STLink. I am using an AMS1117 for power supply, and I have found that when the STLink supplies power at 5V to the AMS1117, it cann...
I recently got a STM32F410RB. The block diagram shows "DAC1 as AF". I have been looking up the datasheet to find the alternate function pin for the DAC module in the "Alternate function mapping" table, but I'm unable to. Also, I see DAC1_OUT under th...
Hello forumI'm trying to implement a project that takes the sensor data and saving it into a USB flash Drive,for that, I'm trying to use the MX system to activate:USBPD - Type C only, TIM2, enabled USB support USBX - Host CoreStack FS, Host Controlle...
Hi,I want to use External 32.768KHz Oscillator as clock source for RTC. This is a reference schematic how I intend to connect Oscillator with RCC_OSC32_IN pin on my STM32H743 microcontroller. My Query is since oscillator requires Vcc 3.3V to operate...
Hello. I have problems with communication with TMC2209 through UART. It doesn't respond at all. I think that I've fried a receiver in UART1. Is that even possible? My board is Nucleo-F303k8. Please help me. Here's the code:/* USER CODE BEGIN Header *...
I am using STM32H743IIT6 MCU to drive HDMI display using LTDC peripheral and Texas Instrument TFP410 for RGB to HDMI conversion. Issue I am facing is I use external crystal as clock source then I see disturbance on my HDMI monitor and its display bli...
Can failed to reinit after deinit. 1. Two cans was used for my projects which was generated by stm32cubemx 2. after run for a short while , I turn off both cans by HAL_CAN_DeInit 3. then I reinit both cans by MX_canx_init and found it failed in HAL_C...
May I know where is the PH3/BOOT0 pin on the STM32L432KC board? I don't see any GPIO pin for that. It is connected to the F103 chip onboard but how do I use that?
If the LSE 32.768KHz crystal is disturbed after the system starts with MSIS auto calibration, and the MSIS clock is used by the PLL for the SYSCLK, the frequency of SYSCLK loses its 0.25% accuracy and starts to drift.Is there any register or interrup...
