I have a device that sends a string of serial data at 300baud to an ECU. This output is standard async 8N1, inverted so that a 1 is 0v and a 0 is +12v. I wish to emulate this device with a PIC, but this outputs TTL voltages. How can I convert the 5v to 12v?
Note that I'm not trying to convert TTL to RS232 levels, ie MAX232 is not suitable.
Cheers,
Chrisall.
