| #use i2c hardware pin error |

I get the following error even though the pins selected are specified as the default hardware pins in the 16F1764 datasheet. (CCS Version 5.055)
C:\__b\CC\Pic16F1764\RANDpwmGen\RandPWM.X\Rand.c:6:5: Error#99 Option invalid Wrong pins for H/W
| Code: |
#include <16f1764.h>
#include <stdlib.h>
#fuses INTRC_IO,NOWDT, PUT, MCLR, NOPROTECT,NOBROWNOUT, NODEBUG, NOLVP
#use delay(INTERNAL = 32000000)
#use i2c(SLAVE, sda=PIN_C1,scl=PIN_C0, address=0xA0)
void main(void)
{

If I do it like this, with all the pin selects, then it compiles. I looked at
the .LST file and it is setting up SSP1CON1 for an i2c slave. I tested this
with compiler vs. 5.056.
| Code: | #include <16f1764.h>
#include <stdlib.h>
#fuses INTRC_IO,NOWDT, PUT, MCLR, NOPROTECT,NOBROWNOUT, NODEBUG, NOLVP
#use delay(INTERNAL = 32000000)
#pin_select SCL1OUT = PIN_C0
#pin_select SCL1IN = PIN_C0
#pin_select SDA1OUT = PIN_C1
#pin_select SDA1IN = PIN_C1
#use i2c(SLAVE, I2C1, address=0xA0)
void main(void)

Yes, that works. I guess the compiler doesn't acknowledge the "default" selections.
Thank you very much. |
