To be used to access an array, rx_char, needs to be a char*, not a char (it automatically is this type, if the declaration is of an array). What is the actual declaration line, for 'rx_char'...

Using CCS 4.053.

*** Error 66 Line 251(51,52): Previous identifier must be a pointer

I have the below code to read from an EEPROM and output several lines at once (rather than having to read the EEPROM for each line which slows it down), yet I don't get any output apart from:

&quo ...

Wouldn't it be easier to use the internal EEPROM? CCS provide commands and examples (EXT_INTEE.C) for this.

e.g. (not checked and it only works if your ID is 8bytes maximum.)

char ID;
char rea ...

Oops sorry, you're quite right, only noticed the NAND gate (74HC00).

Although it may be worth looking at something like a SPDT analog switch (part number escapes me at the moment) in which case you ...

Another way, and the way I use, is to use a analog switch for the RX line. This has the advantage of simply requiring power connections, one wire to PIC, and two wires to the USB/serial connectors.

I'm having a very strange problem with my ICSP and program.

My program uses hardware and software RS232; when it powers on, it initialises variables etc and outputs "Running..." to the so ...

Thanks for your feedback, it is *very* helpful.

Just looked at CAN bus and it seems that only messages of 8bytes can be transmitted?

Thanks very much for your replies, you've both helped clear it up for me.

So, RS-485 is basically RS-232 but with the ability for more than one device? I can use fprintf etc with it?

Thats bril ...

Hiya,

(Using 18F452s, but this can be changed if need be, with CCS 3.249 all at 40Mhz)

I'm looking at interfacing 4/5 PICs together, one master and the rest are slaves, but I need the slaves to ...

Line 1160(15,20): Floating point numbers not supported for this operation

I don�t know what are you trying to do using float, but I guess that you misunderstand the use of float and int32.

...

Cheers, I tried implementing that, but I got

Line 1160(15,20): Floating point numbers not supported for this operation

If I do (int32) typecasting, will it round it up to the nearest integer?
...

I have an int32 which contains a sample frequency in Hz.

I want to convert this to the corresponding delay time.

This works fine, by doing:

//sample_num, delay and sample_speed are all define ...

Does delay_ms support using floats?

e.g. I have a variable, delay, which has the value 3.999999E+01 (from fprintf,"%f,delay).

I then use delay_ms(delay);.

Should this work? I seem to be ...

I am using very similar components (easy radio and PIC18F452).

Something like below should do the job much more simply?
