The Case For Using Parallel Programmer

This is what I ran into for the first time: I was flashing the chip the other day and after many successful runs I encountered the following infamous avrdude error: Continue reading ‘The Case For Using Parallel Programmer’ »

Invoking DS89C430/450 ROM Loader Using Arduino

DS89C430 and DS89C450 are two ultra-high-speed 8051-compatible microcontrollers from Maxim Integrated Products. One unique feature of DS89C430/450 microcontroller is that it has a ROM loader mode which can be used to program the microcontroller itself.

My ultimate goal was to eventually create a full fledged control platform based on this RTC module (more on this later). But first and foremost, I would like to explore its capabilities as an accurate time keeper. Continue reading ‘A Clock/Stop Watch Based on BQ3287’ »
