Flex lcd driver issues with Pic16f1939
PostPosted: Thu Mar 22, 2012 4:27 pm     Reply with quote
Hello,

I have used the flex lcd driver provided here:
http://www.ccsinfo.com/forum/viewtopic.php?t=24661

I am using Pic16f1939 and HDM16216L-S-L30S LCD. It's got the HD44780 controller.

The flex driver works fine with the PIC16f727 and the older version of ccs Now I am using the Pic16f1939 and CCS Version 4.128 and the screen goes blank, the controller won't send out any signal to the LCD.

Code:

#define LCD_DB4 PIN_A0
#define LCD_DB5 PIN_A1
#define LCD_DB6 PIN_C0
#define LCD_DB7 PIN_C1

#define LCD_E      PIN_E0
#define LCD_RS    PIN_E1
#define LCD_RW   PIN_E2

However if I do

Are there any know issues with the Pic16f1939 and version 4.128?


Thanks in advance

Post a short test program similar to the one at the start of this thread:

It must have the #include, #fuses, and #use delay().

Also, finish this sentence, if it was important:

Thank you for the reply, "however I do" was a typo.

The problem was I was using #include <flex_lcd.c> instead of
#include "flex_lcd.c"
The carrot worked fine with the 4.106. After I replaced it with quotation the problem was solved.
