hello,

I am using stm32-h103 board.
I need to get some sensor values through spi and send it to PC.
Can anyone help, how it could be implemented.
i need to store the values inside the controller and do the essential calculation and send it back to PC through USB.
so how to communicate the board with PC thro USB.

Hi manjunath,
The STM32F103 family is given for 4V maximum voltage between VDD and VSS, and some pins are 5V tolerant. You can directly give power supply to the pin you said. But check the real value of your power supply, and if there is no short circuit between some µC pins.
