hello guys. I am Timothy. i have been working on Rs232 and serial communication for a while now. the major issue in the circuit is the max232 I.C . i have observed all rules in its connections, still not working. please help out.
Plug the USB in to the computer.is there any way of testing if a serial to USB converter cable is working properly ?
Almost certainly not, and doing so could well damage it - unless of course the module already includes a MAX232 in order to directly feed a PC serial port.Hello guys. I have a question.
I am trying to interface my microcontroller to a GSM modem.
The GSM module am using is SIMCOM908.
do I still need the max232 in between the microcontroller and the GSM module ?
