Serial EEPROM – A Great Form of Non-Volatile Storage
by Jon Wilder Most PIC microcontrollers have some form of non-volatile EEPROM on chip. However, the largest I’ve seen is 1KB available on the 18F series. There are many applications in which we may need a great deal more than this. The Storage You Don’t Have For instance, what if we have a MIDI device […]

Intel’s MCS-51 Microcontroller Family – It’s Here to Stay
By Jon Wilder As I browse through many embedded electronics forums, I continue to see people making statements referencing Intel’s 8051 line of microcontrollers and how they are “obsolete”. However, nothing could be further from the truth. While Intel ceased production of the MCS-51 family in 2007, there are an abundance of manufacturers still making 8051-compliant microcontrollers […]

IoT from the ground up: MCUs and connectivity building blocks
In the emerging world of the Internet of Things (IoT), the tiny MCU is becoming the mighty MCU. But why and how does a device that has been around for decades figure into the ultra-low-power, connected, and still-unrealized world of the Internet of Things? And why is IoT connectivity any different from the connectivity we […]
Designing a Microprocessor from Scratch
By Val Gretchev, Electro-Tech-Online member Many students in Electrical Engineering learn how to use and program a microprocessor but very few know what goes on inside. This article will give the reader insight into the inner workings of a very simple microprocessor that can be extended to more powerful designs. I will use a visual […]

How To Monitor I2C Communications Through RS232
by Electro-Tech-Online member languer In the past when requiring to monitor I2C communications between two devices I would use a logic analyzer. Such monitoring was useful to determine if the I2C communications between devices was properly configured. Even though this is quite useful and efficient, it does require a logic analyzer, with an I2C protocol […]
