Thanks, I always forget about input-only pins.

When I try to toggle defined pins TRI1, TRI2 as C4 and C5 then nothing happens.
But if i define those pins for example as A1 and A2 then it works.

I can't understand, why C4 and C5 does not work? ...

Thanks!
And reading from eeprom must be looks like:

void read_errors(char * thing, int8 size, int16 address)
{
int16 ctr;
for (ctr=0;ctr<size;ctr++)
*&# ...

Is this possible with PICKIT3?

I have the following type of array:

typedef struct{
int16 hr;
int8 err;
} err_field;

err_field my_errors[10];

How to store it in PIC's EEPROM?

Is it possible to output a value to the upper 7 bits of the port B while B0 works as INT0 input?

How to get T2_DIV_BY_1 or T2_DIV_BY_4 or something else in program at runtime? I mean, the program needs to get timer settings, calculate max duty value and use it on it's own purposes.

Is it possible to calculate at runtime the maximum value for set_pwmX_duty function using Fosc and timer settings?

I can't increase the baud rate due to physical layer limitations. The goal was to minimize time spended for formatting data to send (and time to send too). Because PIC works almost in realtime.

So ...

It is understood about CRC, CRC can be added as 4th variable or can be in vairable "C". I think about the common principle.

I need to minimize conversion time before sending data by serial port.
I have 3 int16 variables A, B, C
So, which code will be faster?:

putc(make8(A,1));
putc(ma ...

Is it possible to generate 457 kHz (+/-100Hz) carrier using PIC?
It is better to toggle some pin or to use CCP? But I can't choose right CCP and crystal settings for PIC10 or 12 series.

Gabriel, do I understand right, that main cycle of program is

/**************************************************************************
// WAIT FOR SMS AND READ
//**************************** ...

Is this driver suitable for SIM800L ?
And how to pass my own string to SEND_SMS() function?

Eduardo,
