In the process of jumping onto the ARM bandwagon, I found a neat tutorial by [J]im Lynch, who has written a highly comprehensive tutorial on how to combine various opensource tools to create an ARM toolchain. He also details what goes on behind each tool right from the hardware level to the software layer. This is a highly recommended read for those interested in using the open source tools for their project including Eclipse, OpenOCD and Yagarto tools. He also gives detailed examples with screen shots on how to setup the following JTAGs – Wiggler, ARM-USB-OCD, JTAGKey, SAM-ICE.

I finally took apart the Spy Video which I got for a very good deal. I wanted to see if it would serve as a good platform for a robot and if the drive system could be upgraded. The most difficult part was taking apart the wheel hubs. The interesting part in the hubs design [...]

This note illustrates how to decode or parse incoming serial data with an example. Transmitting one byte serially to a microcontroller is simple.The easiest way to do this is to interrupt the controller when a byte arrives on the receive pin. There is no need to parse or separate data as whatever comes in, is [...]

I finally get my hands on Analog Devices’ accelerometer- the ADXL202E. It’s small,very small. See what I mean! However there’s this problem, I usually work on PDIP packages and SMDs do give me a scare,not because I’ve never soldered them,but because I do not have the necessary equipment for it. So I decide to do [...]

The device that enables this is a tiny teeny IMEM [aMicro Electro-Mechanical System] which can measure anything between ±1g to ±20g [some of the high g [...]
