Connecting 80 inputs to a microcontroller – I want to check inputs from optocouplers. How can I multiplex the inputs to a microcontroller? I prefer to use the8051, PIC16f877a, or ATMega. Read more. MCP3428 interfacing – I am using the MCP3428 diferential ADC with a single shot conversion and interface through I2C to my microcontroller. It’s […]
Nucleus RTOS aims to wear IoT well
As an established real time operating system shipped in over three billion devices powered by hundreds of different types of MPUs and MCUs, it is unsurprising that Mentor Graphics’ Nucleus embedded RTOS is ready to fall lockstep into the Internet of Things. New SoC architectures designed for IoT require operating systems such as Nucleus optimized for size and performance. What’s […]
Digital signal controllers address power supply challenges
The 14-member dsPIC33EP “GS” family of Digital Signal Controllers (DSCs) from Microchip Technologies delivers the performance needed to implement more sophisticated non-linear, predictive and adaptive control algorithms at higher switching frequencies. These advanced algorithms enable power supply designs that are more energy efficient and have better power supply specifications. Higher switching frequencies enable the development […]

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 […]
