An excerpt from Christopher Paul’s “Parsing PWM (DAC) performance: Part 1 – Mitigating errors”: “I was surprised to discover that when an output of a popular µP...

Pulse width modulation is a terrific basis for digital to analog conversion. Credit goes to features like simplicity and perfect differential and integral linearity. Unfortunately, PWM’s need for ripple filtering tends to make it slow...

The 0- to 20-mA current loop is a reliable means of data communication in industrial applications. These circuits use a precision shunt in the receiver to convert the current signal into a voltage signal...

The basis for this Design Idea is a circuit that uses three resistors and a microcontroller-I/O pin to work as input high impedance or output to independently drive two LEDs...

While the long-lived Z80 continues on in Z180 and eZ80 forms, the standalone DIP-packaged variants' days are numbered...

I2C is a popular bidirectional serial communications bus having a clock and a data line. Both line’s drivers consist of an open drain ground-referenced N-channel MOSFET with a pullup resistor connected to a supply...

The circuit is a single-supply version of a programmable Schmitt trigger, or a comparator with hysteresis...

Seeed Studio has launched a new entry in the XIAO family of small form factor microcontroller development boards, built around the Espressif ESP32-C6: the RISC-V XIAO ESP32C6, boasting Wi-Fi 6, Bluetooth 5.3 Low Energy (BLE), and Matter-ready IEEE 802.15.4 connectivity...

New STM32H7R/S microcontrollers raise embedded-application performance to new levels for next-generation smart devices in factories, buildings, infrastructure, eHealth...

Part 3 will explain the hardware conversion of a CNN and specifically the benefits of using an artificial intelligence microcontroller with a hardware-based CNN accelerator...
