16f627 Rs232

Recommended Posts

I'm going to be a complete pain in the butt here everyone - sorry!

 

Firstly, I am absolutely loving using SourceBoost BoostC.

 

The IDE is fantastic and the language is very clean and easy to understand.

 

OK, to my situation!

 

My project is to build a GPS NMEA signal to LCD using a microcontroller.

 

I would (at minimum) like to take one of the standard $GPRMC or $GPGGA strings that is being

output by a GPS device (a Garmin eTrex), extract the information (lat, long, date, time, number of satellites) and

output them onto the LCD screen.

 

As from my previous post (getting an output onto LCD from a 16F627) you can probably tell that

I'm a "n00b" when it comes to PIC programming. I'm a web programmer by nature!

 

I shalln't be transmitting any data TO the GPS device, simply receiving only.

 

Reading a couple of the posts by other sourceboost forum users I am still very confused -

well, my rugby sesh nickname is "Useless"!!

 

I was wondering if anyone could help me with incorporating the 16F627 on-board USART so that

I can get a HyperTerminal string that I type in (using Windows Xp Pro) and is then output onto the LCD.

(To simulate the NMEA signal).

 

I have already implemented the LCD using PORTB of the 16F672 and this works great. I shall assume I

can use the PIC's PORTA to be my GPS input port using PORTA's pins as the USART TX and RX (although I'll

only need RX)?

 

I have a MAX232 IC - Will I need to use this if I'm simply using my PC serial port and then, ultimately, will be

using a low powered GPS device in place of the PC RS232?

 

I'm trying to not be too demanding - I've read soo many posts where people sound like they are "demanding"

assistance. I don't roll like that, you're the specialists and you're doing us a favour.

 

The only code I have is my basic "Hello World" that is printed to the LCD from the 16F627 so I have nothing

to show you. Pointers in the right direction, basic code examples for the 16F627 would be an excellent help.

 

Many Thanks

You should be up and running in no time with the code and schematic I have send you.

RSABear, I'm also interested. Would you mind sharing your code and schematic with me, too?

I would like this information as well, haven't played with the UART yet, but its my next goal. I don't need the hardware as much as the software.
