I'm going to use the details section to contain the code usedThere are three main modules, and these are all placed in the standard user directory that the ESP 8266 SDK uses for building code.tm1638.h#include "c_types.h" #include "user_interface.h" #include...
When microcomputers first appeared there was, of course, precious little software available for them. If you wanted to use a microcomputer for some particular purpose you were probably going to have to write the software yourself. That was...
Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...
My first micro-computer was an Explorer 85 kit from Netronics Research, which used standard audio cassette tapes for storage. Other storage methods were available at the time, but were far more expensive than tape. Even floppy drives were beyond my budget...
The SBC-85 1Mbit bubble memory board requires buffering, address decoding, a very accurate 4MHz clock, and some power fail circuitry. These components are located along the bottom portion of the PCB. With the decoding and support provided, the...
After the Teensy 3.0 took me to the world of ARMs I quickly wanted to try different chips. While the Teensy boards and tools are great, they are limited to a very specific set of Freescale chips.ST sells ARM chips as well, so I got a nucleo board which...
Emillotron - part 1 The title is a mix (a crasis) between Emilio (my name) and Mellotron. The Mellotron was used in the 1960s, in the time of the Beatles. In those years, long before “digital music”, someone invented a mechanical system...
Our STM32L4 line of development boards has been available on Tindie for a couple of years and we have been making good use of the reference designs and Arduino cores for these in custom projects. Some projects, however, require more GPIOs and/or more...
Introduction of 16x2 LCD 16x2 LCD screen 16x2 LCD specifications LCD 16x2 is used to display status or parameters. 16x2 LCD has 16 pins including 8 data pins (D0 - D7) and 3 control pins (RS, RW, EN).The remaining 5 pins are used for powering and...
Fortunately I came across this great Hackaday page by Patrick! https://hackaday.io/project/9461-lifepo4weredpi He was nice enough to answer questions and help me with my design. My previous 2 layouts were failures, shutting down after only 4A! ...
Due to the requirement of footprint compatibility with the PDIP version of ATTINY85 the board cannot be smaller than 0.4" by 0.4". Unfortunately I was not quite able to get there in this spin of the board. It is still 72 mils too long.For all the large...
