Has anyone done anything cool on ATMEL AT89S52?

 

I've got a while ago a pile of old electronic devices where I sourced maybe a dozen of ATMEL AT89S52 controllers.

 

Briefly looked up the net to see if there are any useful, simple and fun to make projects.

 

Found "magic wand" with 16 LED - which "writes" words in the air when you wave it. (Not interested)

 

Those controllers are also mentioned to be used in the advertisement billboards (e.g. moving word line).

 

If you are in Auckland and have cool project to build - you may have one chip from me (free).

Tend to avoidthe ATMEL chisets myself.

 

 

 

I have a collection of them for select tasks, but my preferred chip is still the ESP8266/ESP32 range.

 

Often make use of ATTinys as expanders if required however.

Thanks for the offer. I found that having chips is only part of the requirements to get started. You need an IDE, development board and some way to program the chip/roms or what have you.

 

This will be good for someone who has all that for this chip/family.

 

Personally, I play with the '51 derivatives from Silabs - when time permits, which doesn't seem very often :-(

Programmer for that one can be done in a few minutes.  I have programmed chips before, not those ones.

Always ironic to see sometimes before you can use a new chip you need to make a programmer ...... with one of those chips !

Making a programmer or any other dedicated tool could be fun in itself. e.g. My old oscilloscope died and for another R&D I need to capture some waveform. Perhaps will make simple oscilloscope myself. For another project with batteries I've built programmable interface. Was fun.

I've been using the ESP8266 to develop an IoT to act as a heat pump remote gateway device. Too many times I left the heat pump running all day needlessly and wanting to turn it 'off' remotely. Also the ability to turn 'on' the heat pump when I'm tucked up in bed in the morning.

 

 

 

Only yesterday I got my first ESP32 Geekcreit development board . Played about using the Arduino examples for the ESP32 and I noticed it's fast to upload sketches and the example WebServer is a lot snapper.

 

The ESP32 is still bleeding edge technology and I'm just waiting for the community update some of the most common/popular libraries to be supported.

I'm loving the ESP32's the dual core has so much usability when it comes to heavy workload.

 

 

 

Certainly dont as cheap as the ESP8266's though!
