I'm just getting started with the STM32, only got the NUCLEO-G474RE board yesterday.I need to communicate from a PC to the STM32 over USB. Am I correct in assuming that the CN1 USB connector is only available for ST-LINK, and I need to attach a seco...
Hello,I have created a bootloader application that jumps to main application at 0x08010000.It works fine, except when I run in debug mode. In this case, the first execution runs correctly. If I push stop and restart button the application goes to STK...
Hi I'm new in working with CAN-bus. My project involves two stm32 boards (both are nucleo-l433rc-p) and I want to get CAN-bus communication between them. The code is supposed to make a build in LED blink each time the blue button on the main nucleo b...
Hello, I'm testing the STM3240G-eval with the USB host MTP. The goal is to retrieve the photo from a canon EOS 100.The camera uses PTP protocol.As the demonstration code read .wav file, I wrote a wav file to the root of the SD card. The digital came...
The current system is configured as shown in the figure above, and the serial communication is using RS485.In the system configuration, UART3 and UART2 are used, and the message from the PC through UART3 is delivered to the device through UART2 from ...

Hello -> We are using a custom board with STM32H745 controller and 8GB eMMC communicated with sdmmc. -> getting SDMMC_FLAG_TXUNDERR bit after writing 64 bytes to eMMC. But i am giving 1k buffer array to write. -> eMMC initialization, reading logic bl...
So I have a abstracted function to read the INA226 component. The function reads the data completely fine over I2C. The problem occurs when I try to display the read data on my dev terminal (Terra Term) over the COM port for STM32. The output on the ...
What exactly is meant by "If Boot from FLASH"?
I'm learning STM32 with the board above and trying to program the ADC conversion.However, when i start debug with keilC and observe the Adc value, nothing happen.I check the ADC register and realized the SWSTART can not be set to start conversion ...
