Character LCDs / RS232 PIC CCS COMPILER COMANDS FOR NHD-0420D3Z-NSW-BBW-V3 ISSUE
« on: May 29, 2017, 02:04:15 PM »
Just acquired NHD-0420D3Z-NSW-BBW-V3 Serial display, I´m currently using PIC 18f4550 on ccs compiler, with recommended standard 232, with the following header #use rs232(baud=9600,parity=N,xmit=Pin_C6,rcv=Pin_c7,bits=8), The LCD 4x20 has the following conections On J1 PIN 1=RX (To TX on PIC) PIN 2=VSS PIN 3=VDD, On J2 just PIN 5=VSS PIN 6=VDD.
I have a simple question, how can I send the commands to the LCD, for example If I want to clear the screen datasheet says 0xFE as prefix and 0x51 as command, but I have no clue how should I send this command, I used printf, putc, puts, and so on.
