We are using STM32G030's internal RTC with LSE. The bypass capacitors we have used as shown in the schematic is 22pf (assuming 1.5pf stray capacitance). The crystal we used has Load Capacitance is 12.5pf. This resulted in the RTC being slow, 1 min pe...
I want to use the second USB of my nucleo-h753zi board, in a program that checks and graphs the movements and clicks of the mouse that enters through the USB port, but I only see the stlink, there is the init = MX_USB_DEVICE_Init (void); I used the ...
Currently I am Trying to make a custom board for a project now I have done all the decoupling things for the VDD pins however I have to give power supply to the VDDA pin and now I am having some trouble since I am not that expert in hardware. I need ...
I want to know the address in the memory map, is it a virtual address or a physical address?
Hey all,I'm trying to enable FreeRTOS for Nucleo-h745zi-q MCU, but I cannot assign timer to sys clock for cortex-m7 core. It shows timer not assigned to m7 code.
Goodmornig,I'm designing a board with an stm32wb microcontroller and I would like to use a type c connector for power supply (some hundreds of mA maximum) @ 5V the board and possibly to transfer data with the microcontroller. No advance type-c featur...
Hello, How to use printf in stm32f429i-disc2 board and my MCU is stm32f103cbt6
I’m interfacing a JXBS-3001-RS Soil Sensor with an STM32L0 board using an RS485 transceiver with automatic direction control. While I can successfully send the request command to the sensor, I’m facing an issue receiving the sensor’s data. Setup: Mic...
I am designing a custom board based on the STM32F407G and need to provide backup power to the VBAT pin using an external battery. my board board must comply with EMI/EMC standards, what are the key requirements and design considerations when connecti...
Hi,I am trying to set-up the ADC3 for STM32H7 but the HAL_ADC_Init() fails ? After debugging, I see that the function LL_ADC_IsInternalRegulatorEnabled() fails in HAL_ADC_Init(). I also see that DEEPPWD is 0 on reset but the datasheet say that it sho...
