Data Storage on CompactFlash (CF) Cards
using BASCOM AVR
In this article we show you how BASCOM AVR enables the Compact Flash Interface for our 89S8252 Flash Micro Board to be employed for DOS-compatible data storage in systems based on AVR microcontrollers.The author’s aim was to be able to use the Compact Flash Interface on an Atmel development board (RIBU ATMEGA103 Test Board) as well as in combination with BASCOM-AVR software, taking into account that the Atmel Test Board does have a lot of port lines, but no CPU-ish pins like RD, WR and ALE which are normally needed to connect external RAM.
