Hi, I am using a 16F877 to talk to a GPS module. It just receives the data once a second and stores it. I am bit banging that one. The USART is set up in interrupt mode and recieves data from another source. When it gets data, I combine that with the GPS data and send it out the USART to a PC via an RS-232 port. It works quite well. Good luck, Fred >From: Olin Lathrop >Reply-To: pic microcontroller discussion list >To: PICLIST@MITVMA.MIT.EDU >Subject: Re: [PIC]: GPS >Date: Wed, 11 Dec 2002 08:15:20 -0500 > > > I would like to connect a GPS card (Rockwell Jupiter) to my 16F877. > > Initially I would like to have the output displayed on the PC via a > > terminal program and eventually on an LCD. > > - I understand how to communicate with the PC via the USART and a > > MAX232. > > - I understand how to communicate with the LCD display. > > - I should be able to write the code necessary to convert the NMEA > > strings into the information I want. > > > > ** What I do not know how to do is to set up a second serial port.
