There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, vacuum tubes, and transistors being some well-known examples. In a smaller ...

Renesas has recently introduced the RA4L1 ultra-low-power Arm Cortex-M33 MCU family along with two evaluation/development boards. This new lineup consists of 14 ultra-low-power devices based on an 80 ...

Displays are crucial to modern life; they are literally everywhere. But modern flat-panel LCDs and cheap 7-segment LED displays are, well, a bit boring. When we hackers want to display the progress of ...

* ... my source is 1.6V P/P with 50 ohm terminatino - then A/C coupled to EXTAL pin with 330pF cap. * WARNING - Using a clock frequency higher than 50MHz is HIGHLY ...

Renesas Electronics RA2A2 Arm Cortex-M23 microcontroller (MCU) group offers a 7-channel high-resolution 24-bit Sigma-Delta ADC, as well as dual-bank flash and bank swap function for an easier ...

On this page I present to you a small instrument capable not only of checking the good condition of a crystal (sometimes unknown when its marking is erased or illegible...) but also of displaying its ...

This project aims to display the information entered in a mobile phone on an LED dot-matrix type scrolling display. It is done by interfacing a Bluetooth HC-05 module to an LED dot-matrix display ...
