In the #defines for the flex_lcd pinout you showed us, you don't have E defined and instead have RW defined with the pin that the schematic shows as going to E.

Here is what you provided:

Code:

In flex_lcd.c the configuration is this (6-pins):

#define LCD_DB4 PIN_D4
#define LCD_DB5 PIN_D5
#define LCD_DB6 PIN_D6
#define LCD_DB7 PIN_D7

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

//#define USE_LCD_RW 1

Notice LCD_E is commented out and LCD_RW is set to PIN_E2, which is what the schematic says should be tied to LCD_E.

You are TOO MUCH !

Thanks a lot to all PCM programmer jeremiah Ttelmah temtronic !! it works!

This is how the lcd of this schematic should be settled.

Code:

#define LCD_DB4 PIN_D4
#define LCD_DB5 PIN_D5
#define LCD_DB6 PIN_D6
#define LCD_DB7 PIN_D7

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

//#define USE_LCD_RW 1
