GNU wannabee and Happy Hacking
For the first experimental version of FST-01, I use STM32F103CB, 48-pin TQFP chip.
For FST-01 size (26mm x 13mm, approximately), I needed to have smaller pad pattern of 48-pin TQFP than recommended footprint.
This is not good. For hand soldering, pad pattern …
I am building DIY SWD debugger for my project. As it seems it works somehow, I am writing this document.
It is not fully tested yet, because software is not ready. Just I tested with current version of Tomek Cedro's modification of OpenOCD. It got IDCODE=EE2805D8 successfully.
Here is the idea of very small computer of mine. Its intended usages are Gnuk, and/or NeuG.
First, the name of company is important, even if it is not (yet) legal entity.
It is named "Flying Stone Technology" after my place in Maebashi.
And the ASCII …
This article is a historical document. Development continues and now we have NeuG, the random number generator.
The entropy source using ADC is same. The major difference is, NeuG uses CRC16 buffer to whiten the entropy source, and uses TinyMT parallel to CRC16 buffer output.
