Hi,
Can I interface directly max232 to STM32F205RBT6.
I have given 5V to VCC of max232 & 3.3V to vcc of STM32.
1. In datasheet of max232, it is given that Vih = 2V. So my 3.3V signal from STM32 will serve the purpose of txd
2. In case of rxd, 5V signal will come from max232 to STM32. Are STM32 pins are 5V tolerant in case I configured them for uart?
3. I have place 150ohm resistor each in between txd & rxd connections of both IC.
