MCUs
Microcontrollers, IOT, and Smart Devices

Back in 1979, years ago, I joined Texas Instruments Semiconductor division as the Telecoms Field Applications Engineer. Hot topics at the time were the TMS1000 4-bit microcomputer, push button dial telephones and how to make them cheaper to build, fully electronic telephones (up to then there wasn't a single transistor in most telephones) (the "trim phone" was a slight exception), and multiplexed digital transmission.

My job was to get TI's solutions designed into the major telecom companies' products, and one of my major projects was the TMS1000 telephone that I worked on with my brilliant friend Peter Roe.

Now, with a bit more time on my hands I am back developing designs with Atmel, and ESP devices.

I am planning to write up some of my projects shortly including:

• Wake on LAN, WOL, device using ESP8266
• IR, Infra-Red controller for any device with an IR remote
• WiFi remote control for models
• Bridge motor controller
• 433 MHz radio controller
• Analysis of 433 MHz radio data with PicoScope and MS Excel
• WiFi Relay switch control
• TMS1000
• Sounds from microcomputers
