RS-422 and RS-485 Electronic Design & Firmware

Ethernet Web Page Control Systems

Ethernet Web Page Control Systems Embedded Microcontroller Way back in the early 1990s, I was commissioned by one of the largest Swimming Pool manufacturers in the UK to design an intelligent Swimming Pool & Spa Bath electronic control system. Back then micro controllers were fairly limited and I opted for an 8bit micro with barely […]

Embedded Electronics

Embedded Electronic Design & Development Professional 16 / 32 Bit Development From John Heritage I have been designing with embedded electronics and embedded micro systems, since the early 1990s, and the industry has progressed on a long way. It fair to say the early micros were fairly limited in power, performance and feature set, compared with […]

Microwire BUS

Microwire BUS Electronic Design & Firmware by John Heritage   Microwire BUS Microwire is a three-wire synchronous interface developed by National Semiconductor and present on their COP8 processor family. Similar to SPI, Microwire is a master/slave bus, with serial data out of the master (SO), and serial data in to the master (SI), and signal […]

RS-232

RS-232 Electronic Design & Firmware by Embedded Design Engineer John Heritage RS-232 RS-232 is one of the very first serial protocols I leaned fully and worked with back in the 1980’s. My BBC B Computer back in the day had a serial port and was technically an “RS-432” port, electrically different to, but compatible with, RS-232 […]

RS-422 RS-485

RS-422 and RS-485 Electronic Design & Firmware by Embedded Design Engineer John Heritage I have worked with the RS-485 protocol when designing DMX lighting control hardware, by using differential line drivers high speed serial data can be achieved in a multi node control system. TIA/EIA-422-B (typically referred to as RS-422) and TIA/EIA-485-A (typically referred to as […]
