Hi
I wrote a program to transmit & receive data from & to a PC and its working fine. It even displays the character I type on my keyboard on my LCD. Now I need to change the program to receive data from a serial instrument & display it on the LCD. Most of the data are displaying correctly but some show up as garbage. Can it be because the instrument uses a 7 bit ASCII protocol & how can I change my program to work with 7 bit data?
Hardware or software?
From the manual under SERIN2
[quote]
A DEFINE allows the use of data bits other than 8 (or 7 with parity).
SER2_BITS data bits may range from 4 bits to 8 (the default if no
DEFINE is specified). Enabling parity uses one of the number of bits...

To what manual are you refering?
The only manual I'm using are the PICmicro Mid-Range MCU Family Reference Manual & the PIC16F877 Data Sheet.
I'm using USART on port RC6 & RC7 to transmit & Recieve.
The Pic Basic Pro or Pic Basic manual.
You are not using either one are you? Well that is the language we use here. What language are you using? Might be able to point you in the right direction.

But I have to give a plug for basic :)

They have a demo

Yes it cost some, but soooo much easier. At least we think so here.
Have a good one!
