Hi,
i have some doubts here want to ask,
May i know there is a need to use rs232 or max232 circuit for communication between 2 microcontroller?
As i know, RS232 logic is just use in PC. So, if both microcontrollers also using TTL logic, why we still need to use max232 for rs232 conversion?
i am little bit confusing about this.
Thanks.
