I am very impressed with the CCS forum. Its an excellent resource, especially if you're not a full-time PIC programmer but have to keep going back to it. I wasn't aware of the "ROM" change, ...

Thanks for the clarification. Your syntax works perfectly. I was confused by reading The compiler does not permit pointers to functions so that the compiler can know at compile time the complete call ...

Hey guys,

Simple question. I want to use a fn as an argument in another fn. So of course I'm using a function pointer. I looked up the C syntax just to make sure I wasn't crazy, and it matches what ...

and to do a read in the slave isr for address 0x80
No address of 0x80 is sent. The 0x80 (and other values) comes
from the CCS function i2c_isr_state(). It is described in the CCS manual:
http:// ...

Thanks for the info. The NXP spec is helpful. I also just learned from skimming it that I2C reserves certain addresses.

But CCS really should have made it clear that only the master can NAK in thei ...

PIC- 18F4520
Compiler- PCH 4.085

I was playing around with an example I2C master and slave provided by PCM Programmer using two PICs on different PCBs. The examples work great but I discovered a p ...

Here is a simple i2c slave demo. The slave PIC reads the ADC value
every 500 ms and saves it in a global variable. This emulates a sensor.
The master PIC reads the ADC value from the slave. The ...

Hey Andrew,

I actually did see the sentence "A Bulk Erase is the only way to reprogram
code-protect bits from an ON state to an
OFF state."

But since the bulk erase operation is co ...

What you want to do is theoretically possible, but not with your current hardware (programmer) and software.

Microchip have a relevant programming specification document:

It's very easy to program a PIC chip without touching the EEPROM if you use a pickit 2 or 3 with their software. So that's a possibility if you have no other way to do it. Pickit2 is pretty cheap.
