Possibly a GPS for the DS

How to make one.








natrium42 shows on his wiki how to connect a GPS module to the DSerial motherboard, said setup would turn the DS into no less than a GPS receiver.

This project shows how to connect a serial GPS module to DSerial.


First, determine whether your GPS module uses RS-232 level or TTL/CMOS level serial port. See this article for explanation of the difference. If it's TTL/CMOS level, then MAX3221 converter should be disabled by setting "UartEn = 1" in the firmware and the GPS module should be connected to IO2 Rx/Tx lines.
If it's RS-232 level, then MAX3221 converter should be enabled by setting "UartEn = 0" in the firmware (default setting) and the GPS module should be connected to the RS232 connector.


The following shows how a Lassen iQ GPS module is connected. It uses a CMOS level serial port and draws only 26mA, so it can be powered directly from DS. GPS NMEA strings are continuously sent to DS at 4800bps (by default) and can be viewed in the console.

He originally made a post on his blog about this in Aug 2005.

Considering nothing has been done with it since, I find it hard to imagine anything will happen now.

Somehow I don't think I would feel safe carrying a makeshift GPS.
