samDEV_09 – Mini devboard for Atmel’s SAMD09 ARM Cortex M0+ Microcontroller
https://www.electronics-lab.com/samdev_09-mini-devboard-atmels-samd09-arm-cortex-m0-microcontroller/
A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and therefore has […]
Simple nanosecond-width pulse generator provides high performance
https://www.electronics-lab.com/simple-nanosecond-width-pulse-generator-provides-high-performance/
by Jim Williams @ edn.com If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of Figure 1, built around a quad high-speed comparator and a high-speed gate, has settable 0- to 10 ns output […]
