 Most of the time I design and debug my AVR projects on solderless breadboards nowadays. And for that I have been using some different types of programmers by now: starting with the good old STK500, to different versions of USBasp clones from Chinese sellers on eBay. In order to connect the programmers to the […] Continue reading An USBasp in a new design II  Just a small teaser: today I received my circuit boards from PCBgogo – a layout which I just had sent to the Chinese manufacturer last Sunday. The finished circuit board from China. It is a USBasp, which can be placed on a breadboard and at the same time supplies the power rails […] Continue reading An USBasp in a new design  A couple of years ago I mounted an Atmel STK500, a couple of breadboards and a power supply in a briefcase. This allowed me to bring test circuits to my lectures and demonstrate them in the class room. The briefcase with the STK500 still mounted. Since I now have abandoned the STK500 […] Continue reading A portable electronics bench  After the first two parts of this series ATmega328P – measuring its own supply voltage ATmega328P – measuring its own supply voltage II where I investigated the possibility of the Atmel ATmega series microcontrollers to select the internal bandgap voltage VBG as input for the analog-to-digital converter. Using the analog supply voltage AVcc as […] Continue reading ATmega328P – measuring its own supply voltage III  Here is a brief follow up from yesterday’s post on the internal reference voltage VBG of the ATmega328P. I wrote a small test program where I wait for a variable delay time after switching the input multiplexer of the analog-to-digital converter to the internal bandgap reference voltage VBG. Using the AVcc of as the […] Continue reading ATmega328P – measuring its own supply voltage II  The trick is not new, it is utilized in the AVR transistor tester which you can buy for quite cheap money from China, and it has been discussed in internet forums for almost 10 years (see below for some links). The Atmel AVR microcontrollers feature an analog to digital converter (ADC) equipped with […] Continue reading ATmega328P – measuring its own supply voltage  My very own AVR ISP adapter on a breadboard. Breadboards are great! I mean the solderless breadboard type which you can get everywhere now for almost no money. I use them all the time to prototype electronics circuits and have been forcing my students to do the same. Most of my current […] Continue reading AVR ISP breadboard adapter  https://www.sciencetronics.com/greenphotons/wp-content/uploads/2013/12/5x7_led_weihnachten.mp4 https://www.sciencetronics.com/greenphotons/wp-content/uploads/2013/12/5x7_led_xmas.mp4 https://www.sciencetronics.com/greenphotons/wp-content/uploads/2013/12/14seg_xmas_500bps1.mp4 https://www.sciencetronics.com/greenphotons/wp-content/uploads/2013/12/14seg_weihnachten_500bps.mp4  (see also my recent appendix to this topic: Hacking an AVR programmer II – especially if you have an ATmega88-based programmer!) On eBay I recently purchased a set of cute small USB AVR programmers which I intend to use in the course 1TE663 Microcontroller Programming at Uppsala University. MK-USBISP-V3.00 programmer in an […] Continue reading Hacking an AVR programmer |
