Yeah, you get strange errors if your parentheses are not closed, too. Every c compiler I've worked with has some freaky things, and you get used to them. I...
I finally got my GPS unit in but I'm having a heck of a time getting it to connect. It is a Garmin GPS15 and has 0-3.3v CMOS serial output (two wire). I'm...
Hi Jon, I really appreciate your reply and if you do find the time to research what might have been suggested by Rabbit that fixed the issue for you I would be...
Garmin GPS15 L which is the low power version which wants a power voltage of 3.3v to 5.0v. There is also a GPS15 H version which requires a much higher...
There´s no need for complicated things on this school project. He simply want to GET data from an internet server every 5 minutes. Just use the RTC to count...
Larry: Thanks for the ideas. Actually there are three versions of the GPS 15. The GPS15H/L are RS232 versions and then there is a straight GPS15 which is the...
Greetings: I am trying to implement RS-485, NRZI HDLC communications between my Rabbit RCM3720 development board and legacy ZILOG SCC based devices. To my...
Hi For testing please connect your GPS to PC serial port and open Hyper Terminal, configure it to 4800, 1 STOP, 1 START, NO PARITY. Check are u able to see any...
Thanks Fakhre but if you'll read my previous posts, I have tried all of this. The GPS sample application just sits idle after it displays the demonstration...
How big is your receive buffer on port c and are you delaying or being stalled off. I will be happy to reconfigure my 3200 system and give you the code which...
Kelly: I believe your rabbit programming cable is nothing more that a level converter to RS-232. You might consider using this to test your GPS with a...
I remember dorking around with this a couple of years ago. I couldn't get access to those bytes. Ended up appending a couple of extra bytes into the stream...
Hi I checked the data sheet of GPS15, its output is 0 to 3.3 v, its can be directly connected to PORTC RXC pin of rabbit. Please open the gps.c file and add...
Larry: I set the receive and the transmit buffers to put 127... at least I think I did! Are you referring to the #define CINPUTSIZE and COUTPUTSIZE commands...
Well heres a little update on the ol' GPS conundrum. Tonight I took the time and built a CMOS to RS-232 converter and hooked the GPS up to my laptop. It...
Well I've discovered the mystery to why reading a GPS was such a hassle... and possibly why my PWM's quit functioning. Something on the prototyping board has...
My freind, I have used the 3200 board in many projects including ones with PWM on multiple channels and it always worked. Good that you have isolated the...
Rightyo, it looks like WiFi modules don't allow you to choose between using DHCP and static IP at runtime, only during compile time. That's an important one :)...
As the original designer of the SCC and all Rabbit microprocessors, I can guarantee you that they all use exactly the same (standard) CRC algorithm. In fact...
Take a look in the samples\tcpip\ftp directory. There are samples of being either a FTP client or an FTP server. Joel Baumert Director, Engineering Rabbit...
Hi to all, I need to echo chars received from port A (DIAG connector on programming cable) to port F and viceversa. First, I try this: void main() { char c1; ...
Hi all, Long introduction (apologies in advance).... I am trying to write a program to convert data to and from a 375kBaud HDLC source and a TCP/IP socket. I...
Thanks for that. Most of our clients here is Australia would be able to set asside an IP range for static addressing or set up a DHCP server for dynamic...
* Becuase 1 application is easier to maintain than 2 * Because as an option is it easier to change from one to the other, press a button on a screen rather...
Marco, I am not sure what is going wrong with your program. There is not anything obviously wrong. Try looping it between a serial port other than A... Feel ...
Jack, It does not seem like 20Kbits/second should cause you problems... What speed do you start seeing problems? Is the other side writing in blocks? Do you...
