MicroVGA KIT91SAM7S
The KIT91SAM7S-MicroVGA is a low-cost ARM7 development kit for use with
the MicroVGA-TEXT. It is recommended for everyone who is starting
with the MicroVGA. The board comes pre-loaded with firmware and can
be programmed using free tools (GNU CC for ARM7 and Atmel SAM-BA), no
additional programmers/interfaces are required. Demo
source code is available for free, which means that you can start
evaluating the MicroVGA immediately, without having to hassle with
microcontroller setup or communication issues. Furthermore, the board
contains powerful ARM7 MCU
(AT91SAM7S256) providing
60MIPS computing power and a lot of useful peripherals.
The board can be used in standalone mode, without the MicroVGA. However, the real fun is with the MicroVGA connected!
