Introduction to I²C and SPI protocols
https://www.electronics-lab.com/introduction-i%c2%b2c-spi-protocols/
byteparadigm.com has a nice introductory article on I2C and SPI protocols: Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for communications between integrated circuits, for slow communication with on-board peripherals. At the roots of these two popular […]
Benefits of Using A Buck-Boost Converter As A Pre-regulator For LDOs
https://www.electronics-lab.com/benefits-using-buck-boost-converter-pre-regulator-ldos/
Intersil published a new white paper titled “Preventing Subsystem Brownouts in Mobile Devices“. This white paper demonstrates the benefit of using a buck-boost converter as a pre-regulator, which leads to better overall system efficiency and enhanced battery life. Systems powered from a battery may have voltage brownout when they are subjected to a burst current […]

Intersil announces the adoption of its latest family of buck-boost switching regulators in one of Huawei’s newest smartphone. The ISL91110 buck-boost switching regulator powers the Huawei P9 smartphone’s key system peripherals providing excellent efficiency and performance. [via] Intersil’s ISL91110 buck-boost switching regulator supplies power to key system peripherals in the P9 dual-camera smartphone, using a proprietary, fully […]
Adding ADC to Microcontrollers without ADC
https://www.electronics-lab.com/adding-adc-to-microcontrollers-without-adc/
Scott @ swharden.com show us how to interface an analog signal to a microcontroller that doesn’t have an ADC. I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two […]
Analog front-end IC linearizes sensors
https://www.electronics-lab.com/analog-front-end-ic-linearizes-sensors/
Susan Nordyk @ edn.com discuss about LTC2986 which is able to digitize and linearize a combination of temperature sensors in Celsius or Fahrenheit degrees. A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples, RTDs, thermistors, and external diodes with 0.1°C accuracy and 0.001°C resolution. The analog front-end device combines […]
MPPT Solar Charger Design based on PIC18F26J50
https://www.electronics-lab.com/mppt-solar-charger-design-based-pic18f26j50/
Lukas Fässler shares his Maximum Point Tracker Solar Charger Design based on PIC18F26J50: At the core of the design is a PIC18F26J50 in a 28 pin SOIC package. It’s capable of running at down to 2.15 volts and consumes extremely little power when running at lower clock speeds. And apart from that it features USB […]
CO2, temperature and humidity monitor
https://www.electronics-lab.com/co2-temperature-humidity-monitor/
An open source CO2 monitoring project from Roving Dynamics: The project described below uses a MH-Z16 or MH-Z19 CO2 sensor and a DHT-22 (or DHT-11 if less accuracy is required) to measure the Temperature and Humidity. It has a 4 line by 20 character LCD Display to show the current readings and status, a warning alarm […]
Ultrasonic Anemometer Project Progress
https://www.electronics-lab.com/ultrasonic-anemometer-project-progress/
Lukas Fässler discuss about his anemometer project progress and what tests he has performed so far. In the mean time I managed to do some rudimentary testing and now feel confident to take orders. These tests concern the hardware only. What I said last time about the state of the software still applies. But let […]
