thanks, they are "variable" constants in a separate file which are calibration constants to each micro but change for each device (separate file for each product)! As the compiler knows wher ... |

Hi,
Is there an easy way to bit_test a constant? the in-built bit_test function doesn't allow it. |

It needs to be the really tiny footprint part; I am just tasked with firmware! Apparently (I haven't checked!) it's the smallest F part with EEPROM you can get! |

Here is my code:
#byte FSR = 0x4
#bit BANK = FSR.5
#byte EECON = 0x1
#bit FREE = EECON.4
#bit WREN = EECON.2
#bit WR = EECON.1
#bit RD = EECON.0
#byte EEDATA = 0x5
#byte EEADR = 0x6

Hi, from what I can see from the datasheet the 12F519 has real(ish) EEPROM which you need to erase a whole 8byte row before you can write a single byte. I think you are referring to the non-flash part ... |

Figured it out; ccs compiler bug, will post a workaround this evening so no-one else drops in the hole! |

Thanks, but I get:

The #use i2c doesn't seem to like those pins? |

Hi,
Wondering why I can't do this:
#byte CCP6CON = 0xF71
#bit CCP6IF = PIR4.1
#bit CCP6M0 = CCP6CON.0
and in my code:
if (CCP6MO++) {
rise3 = CCP_6;
} else ... |

Thinking out loud! Can you redirect the pins of a UART on PICs such as the PIC18F27J13 in software? I.E. Can you change the function of the pins on the fly in code, it would be nice to redirect the TX ... |

Thanks. That looks a great foundation. Yes slow rate, slow transmission process! I wish I could tell you more!
Keep well,

Wondering if anyone has any code for a software uart running at a baud rate of 2 to 5. It seems the CCS in-built functions only work at 6 and above! I only need transmit. Or is there a work aroun ... |

Thanks, looks a very neat solution to me. I was using up precious code to do this with variables. |
