True. I started counting from 1, not 0 :-).

Thanks
thank you
its helped me a lot

You are right that unfortunately, the manual does not say much about this.

Suite of things:

First, though the buffering is automatic, you do need to have
'enable_interrupts(GLOBAL);' at the start of your main, or the buffering will
not be enabled.

There are also a few posts on this board about using the RECEIVE_BUFFER option in #use rs232

example:
#USE RS232(BAUD=115200, UART3, BITS=8, PARITY=N, STOP=1, STREAM=PC, ERRORS, RECEIVE_BUFFER=128 ...

#INT_RDA
void RDA_isr(void)

NAVID, you were told back in August 2017 not to do this.
You were told to only get one byte per interrupt, and not
to use a for() loop ...

Fortunately, if he is using one of the standard shields designed for the Arduino, these have got FET level shifters built in, If he is not using a circuit like this, then there will be problems.

hi ...

I have to ask a basic hardware question.
Is the 'sim800c' designed to operate at 5 volts? The 877 is a 5 volt PIC so if the sim800c is a 3 volt device, it cannot interface or work properly.
You shou ...

Your approach is fundamentally flawed.
:D

INT_RDA, means _one_ character is available to be read. Just one.
Not 32.
so what i must to do??!! its my receiver interrupt...

Then you are looki ...

Hello everyone I have a problem with communicates sim800c. I use pic16f877a and i can send commands to sim800 and it works correctly but i can't display its answer...
This is my code. I hope somebody ...

hi...i solved it!!!
the adc was work correctly when i increased the delay...but its not showed on lcd!!
so i wrote a function named "display" and call it every where in program to

I'd try something like this....

please post your current program...
maybe we can see the error.

sure...tnx for help

What is the problem when you run real hardware ?
You have never told us.

You told us the problem with Proteus is the error message:
"ADC conversion started before 'wait' time has expired fo ...

OK. I'd say that the error is just a fault with Proteus.
I've seen exactly the same on another chip, where the acquisition time is hardware programmable, and was set to MicroChip's recommendations, d ...
