RS232 Driven True vs Driven Inverted
Posted: Wed Aug 15, 2012 8:26 pm
I'm using a PIC16F688 with PICBASIC PRO Compiler to run a LCD2041 rev 1.5.
The RS232 TX output from the PIC is wired directly to the power connector pin 3. The 3 TTL connections are soldered closed. J3 is jumpered for 9600 baud, and the RS232 jumpers above the DB9 are installed.
This works fine as long as I set the RS232 output to "Driven True" (T9600 in PICBASIC)
Is there a method to run the LCD using RS232 "Driven Inverted" (N9600)?
