| 16f88 lcd on port a |

I am trying to setup the lcd using the flex lcd driver. I have gotten it up and working on port b and I was trying to set it up on port a. I keep getting an error when I add the lines to turn off the adc.
I am using a 16F88 with the compiler version 4.021
when I uncomment the acd setup lines I get the error "Command returned error code:1Halting build on first failure as requested." with the lines commented the program compiles correctly but the lcd does not work. I will not even initalize.
| Code: |
#include <16F88.h>
#fuses INTRC_IO // internal RC, I/O on pins A6,A7
#fuses NOWDT // no watch dog timer
#fuses NOPROTECT // no code protection
#fuses NOLVP // no low voltage programming
#fuses NOPUT // no power up timer
#fuses NOMCLR // I/O on mclr pin
#fuses NOBROWNOUT // no brown out reset
#fuses NOCPD // no EE memory protection
#fuses NOWRT // no flash program write protection
#fuses NODEBUG // no in-circuit debugger
#fuses NOFCMEN // no fail-safe clock monitor
#fuses NOIESO // internal external crossover mode disabled
#use delay(clock=8000000)
// #use rs232(baud=9600, xmit=PIN_B5, rcv=PIN_B2)
// #include <stdlib.h>
#define LCD_DB4 PIN_A4
#define LCD_DB5 PIN_A5
#define LCD_DB6 PIN_A6
#define LCD_DB7 PIN_A7
#define LCD_RS PIN_A0
#define LCD_RW PIN_A1
#define LCD_E PIN_A2
#include <Flex_LCD416.c>
//===================================
void main(){
//setup_port_a(ALL_DIGITAL);
//setup_adc_ports(NO_ANALOGS);
//setup_adc(ADC_OFF);
int8 i;
int8 b1, b2, b3, b4;
// The lcd_init() function should always be called once,
// near the start of your program.
lcd_init();

1. setup_port_a() and setup_adc_ports() are the same function.
It says this in the 16F88.H file:
| Quote: |
SETUP_ADC_PORTS() (aka SETUP_PORT_A)
|
You don't need to call it twice.
2. There is no "ALL_DIGITAL" constant in the 16F88.H file.
The constants are as follows (from the .H file):
| Code: | // Constants used in SETUP_ADC_PORTS() are:
#define sAN0 1 //| A0
#define sAN1 2 //| A1
#define sAN2 4 //| A2
#define sAN3 8 //| A3
#define sAN4 16 //| A4
#define sAN5 32 //| B6
#define sAN6 64 //| B7
#define NO_ANALOGS 0 // None
#define ALL_ANALOG 127 // A0 A1 A2 A3 A4 B6 B7 |

1. Post the manufacturer and part number of your LCD.
Also post a link to the data sheet.
2. Post a link to the driver in the Code Library that you're using.
3. Did you modify the driver in any way ?
(Other than the pin numbers). |
