Hi bkamen,

My friend / supervisor has been in touch with Microchip and the first thing they told him was to make sure the chip is certified for 40 mHz operation at the voltage used to run the chip ...

Hi Everybody,

It took me a few days to isolate exactly why my programs locks. This code demonstrates the problem:
#include <18f2321.h>

#define UpArrowKey PIN_A6 //Up arrow

Hi Everybody,

I'm using a 18f2321 with V4.109 compiler. I'm using a 10 mHz crystal.

When I configure the oscillator using this code the system works fine:

#use delay (clock = 10M, oscilla ...

I've the same problem here. I'm using CCS IDE version 4.107 and PCB, PCM, PCH, PCD version 4.107 with ICD-U64. Please help.

The best work around is to define each ENUM value as a constant.

Foe e ...

Hi everybody,

Reloading the compiler and CCS' IDE (now V. 4.103) did not solve the problem, but I found an interesting clue.

I simplified the code as much as possible

#include <18F2321.h ...

Hi PCM programmer,

I just compiled your code and it still gives me wrong ID's. I'll reload CCS's IDE and post if that does not solve the problem.

Thanks for your help.

Hi everybody,

I'm using 4.104 compiler version with a 18F2321.

I have the following declaration:

enum Modes{InternalMode, ExternalMode, EncoderMode, StandByMode};

When I mouse over th ...

You can't 'or' these together.

D'oh!

Thanks for your help,

Hi Everybody,

I’m learning the CCP system on the 18F2321, and using version 4.105 compiler software.

On one pass through the ISR the hardware resets Timer3. I turn the output on and set how l ...

Finally, add a pull up resistor on the line from the RO pin to the PIC's RX pin. 10KR or similar.

This turned out to be the problem. !2 hours down the drain because the engineer ...

You are sending async serial over RS485. No RS232 involved anywhere, so why say 'RS232 link'....
Just because CCS are stupid and refer to the TTL async port on the PIC as 'RS232', you don't have ...

I need to clarify something in my post.

Ttelmah already gave me the program I asked for (Thanks!) The real problem must be in my modificat ...

Your thread is entitled 'RS232', yet you are using RS485....
Not a good start.

Not really. From the Wikipedia article on RS485 (Formally called EIA-485)

"EIA-485 only specifies electrica ...

Hi everybody,

I need advice on setting up a bi-directional rs232 link.

I'm using a 18f2321 with v 4.104 compiler software. I'm using the UART hardware so the MULTI-MASTER mode is not available. ...

understand the difference between '\r', and '\0'.

Thanks Ttelmah!

I'll also put a scope on the data lines tomorrow - the design is proven but an IC might have been damaged by static or handl ...
