datalogging from pic16f877a to usb-stick

[arie]

I've got a tricky project involving a gps receiver sensors and a pic16f877a.
I would like to receive gpscoordinates and store it on a usb stick with data from different sensors attached to a motorcycle. Its a datarecording system. The tricky part is the datastorage cause pic hasn't enough memory.

Does anyone kno how to connect a usb stick to a pic16f877a and how to send data to a memorystick?

Not to a memory stick. But how about to an SD card?
Take your PIC, get the datalogging working, hook it up to a "DOS-On-Chip" chip (www.sparkfun.com, search for Dos-On-Chip), add an SD card slot, start datalogging. Take the card out of the slot, put card into card reader at your PC.

Probably a hundred ways to do this...You can have it 2 of 3 ways...
Cheap and simple, but it won't be good...

Hi arie,

Welcome to the forum.

Some of the beginner’s answers can be found using the site’s search function.

For instance this previously posted answer. It refers to a “Bluetooth device” but applies to PICs hosting USB in general.

As far as I know PICs can only be used as a USB Device not a USB Host as you would require to connect the USB Bluetooth device. To do this you would need to get a USB Host controller and connect it to the PIC. Unfortunatly I havn't seen anyone do this yet but if I do I will post more info.

skimask is correct not a simple task.

Thank you very much for the help.
Can you write data from pic to dos on chip module just using hserin or is it much more complicated?

thanks a lot

The datasheet is right there at www.sparkfun.com

I read the datasheet for the dosonchip, but how do you read and write data from the sd chip\?

Do you need to tell which memory adress you want to write or read or is this done automatically with hserin hserout?

i use pic basic pro
