Signal generation and measurement EN_CLOCK_GEN This module is based on the 3 channels version of the Si5351 clock generator chip. The compact board integrates an SI5351 clock generator, a micro controller Atmega328p, a digital selector and a liquid crystal display. This is a very lightweight solution to produce 3 independent clocks for your prototyping projects. Main […]
A relatively simple implementation of a one button menu on an Arduino board using readily available libraries. There are many methods and code examples available to implement a menu on an Arduino board. For my current project I chose to use a one button menu to reduce the footprint of this functionality. I don’t […]
Saving power has become a main concern when designing electronic circuits and it is now mandatory to incorporate a power saving system to get the CE certification. Hence microcontrollers like the Atmega328 incorporate a full set of energy economy functions. Section 10 of the Atmega8 to 328 datasheet explains the “Power Management and Sleep Modes”. […]
Today I came across some very interesting videos about professional frequency measurement error ( Agilent 53131A Frequency Counter Oven Upgrade) and it gave me the idea to better the precision of the frequency counter I am working on. I was quite happy until now with the accuracy of about 100 ppm measured on the Arduino […]
Dear web-surfer, after quite a long time designing the Freq_LF_HF board and preparing content, Pandauino? webiste is now launched! What do you think about our logo?
