Re: Query about GM 862-gps - How a python script can burn on
Hi,
Look at:
**broken link removed**
There you have a HW, SW user guides, etc.
You should look also for RSTerm which is also on that site

Re: Help: Problems on interfacing PIC18F252 with GSM Modem.
Hi,
You may also build some RS232 sniffer to check the commands, e.g.
https://embeddedfreak.wordpress.com/2008/08/17/rs232-serial-sniffermonitoring-circuit/
Just write "RS232 sniffer" on google and get the best fitting to your needs
Re: very important
Hi,
What do you mean writing:
Do you want to make some? Or do you want to show as some of yours? Or maybe do you want us to send you some type of it? Or maybe help in making it?
I don't think it can give you a negative values. You've got some SW bug, e.g. some unsigned/signed conversions? Or sth like that. Let us see more of your code maybe? Write what value are you measuring and what your device is showing.
Do you have a MAX232 or sth like that between PIC uC and a PC serial port?
Do you have an oscilloscope to check signals on uC pins, before PC serial port?
Re: how to convert row elements two dimensional array to str
So when it has characters it's even better :)
Here's an example which I've checked a moment ago
#include <stdio.h>
int main(void)
{
char A[2][2] = {{'h', 'i'}
, {':',')'}};
char string[20];
int i = 0...
Hi,
But this is a very simple code, so why do you want simpler one? :)
You have to check where is the problem. Check if rec1 and rec2 react on changes in P3.6 and P3.7, check where you get stuck, etc.
Don't give up so quickly. When you will make it running I'm sure you'll be proud of yourself...
Hi,
First thing - are baudrate of you UART the same as baudrate of module?
And second one - do you have an oscilloscope to check if sth is getting out of the buffer?
Re: how to convert row elements two dimensional array to str
Hi,
For example you could take every element of your array in a loop and "paste" it to the string by using strcpy and strcat library functions.
When you want to have a circuit which will protect from switching Vcc with GND on the power supply the simplest way in my opinion (tell me if I'm wrong) is the diode bridge
https://en.wikipedia.org/wiki/Diode_bridge
which will always give good polarity of voltage.

ds1820 temperature sensor
Exactly DS18S20 is a digital sensor which communicates with a 1-wire protocol.
Read about it, implement it (see the www.maxim-ic.com for more info - exactly: **broken link removed**) and it'll work excellent.
Re: Hi everyone! need help guide in communication pc and mic
Hi,
Just google e.g.: uart (or serial port) c example + ucontroller (e.g. avr, msp430) and you will have many of them.
Few seconds of searching:
