Completed interfacing an LCD panel with the USB PIC, thanks to Anish. We are still not able to get interrupt URB’s working properly - except that, everything is OK.

Coming next: A comprehensive tutorial on developing USB gadgets with GNU/Linux and PIC! We hope to get it published as an LDP HOWTO.

Microchip/Circuit cellar have announced a 16 bit embedded control design contest - the idea is to promote the use of the dsPIC family of controllers.
Microchip is giving out a generous sample of components to the contest participants - here is what I got:

I find the ENC28J60 device very interesting - it’s an ethernet controller […]

Even though USB has become wildly popular, there are not too many resources on the web which gives you a tutorial introduction on how to go about developing USB peripherals and controlling them with GNU/Linux. Anish and myself have started work on creating a simple USB gadget - we intend to document the process […]

Here is a photo of two `tiny’ microcontrollers I had purchased recently; the bigger one is the ATTiny15 in an 8 pin DIP package and the smaller one is the PIC10F206 in an SOT package. The PIC costs only Rs.25 […]

Got two interesting things to experiment with yesterday - the Motorola Linux smartphone A780 and the PIC18F2455,a flash PIC with USB 2.0 support.

There is a project underway to provide a 100% free software stack for the A780, the OpenEZX project. Will try to get a few students interested in this…stay tuned for more info […]
