USB Port on Board Card

Guyome

Hello, I want to know if it is possible to connect a USB port to connect any device (key bluetooth, wifi, webcam .....) on a map of education boe-bot.
As well as retrieve information from the peripheral device and treat.

Thank you in advance,
Guillaume.

I assume you have the USB version of the Board of Education on your Boe-Bot. That provides a USB client which can only connect to a USB host (usually a PC). If you want to connect another USB device to the Board of Education, you will need some kind of USB host device on the Board of Education. The Parallax Memory Stick Datalogger can function as a USB host and can be attached to the Board of Education, but it's very limited in the kinds of USB devices it can work with. It can use USB memory devices, keyboards, mice, and very simple printers, but nothing else, nothing like a Bluetooth or WiFi key or webcam. The USB host device has to know how to control the USB client devices. With a PC, the operating system, like Windows, has a huge library of USB device drivers and can download more or have them installed from an installer program that comes with the device, but something like the Datalogger has only a few simple device drivers and no realistic way to add more.

Thank you for answer, I suppose the reason is not possible to connect a peripheral device is the software part ?

The reasons are both software and hardware. The USB client chip on the Board of Education has only one use. It can provide a virtual serial port and it requires no special software on the Stamp. The Memory Stick Datalogger uses a different chip designed primarily to allow access to USB memory devices. It happens (because it's pretty simple) to also allow access to HID (Human Interface Devices) like keyboards and mice and simple serial printers were close enough that they included those as well. The limitations on device types is mostly software (in the interface chip).
