USB GPS interfacing

GPS/GNSS Development Boards
1

I have an apparently unique project I hope you might help me with. I have a USB Gps device that I want to connect to a microcontroller. I’m wondering if I supply 5 volts & gnd, can I pull data from the devices data lines? If not, I’m looking at BOB-08551 and wondering if I can use it in reverse of it’s design. In other words, connect the gps data lines to the converter (usb side), supply 5 volts & gnd and get data out from the serial side.

I want to take the data from the gps, extract the data that I want and display it on an lcd.

I hope you might shed some light on this little project. Thanks in advance.

It would be easier to get a standard GPS module and interface it via a serial port. If you really need a USB interface you need an MCU with USB OTG, and are into a lot of work.

Thanks Leon for the reply. I realize that it would be so much simpler to get a GPS with a RS-232 output. I’m trying to use the device I already have. By the way, what is ‘USB OTG’? I already have an MCU that I’m using with this application. Do you know if I can pull raw data from the USB GPS data pins?

Thanks for your help.

USB “On the Go” - it’s a simplified host mode that is available on some MCUs. The alternative is a Vinculum chip.

Sounds Like you and I are working on a project that is real close to each other in the required comms.

I too need to take USB GPS data and pump it through a serial device.

Mr Heller, could you elaborate?
