USBasp - USB ISP/TPI programmer stick for Atmel AVR microcontrollers with 5V and 3.3V target voltage based on the design by Thomas Fischl. More information can be found at https://www.fischl.de/usbasp/. Windows users may need to install a driver. Of course this is not necessary for linux and mac users.
|TGTVCC|Close to power target device via ISP header|
!!! ERROR in the current revision: DO NOT USE D4 18V ZENER OR INPUT VOLTAGE MORE THAN 19V !!!

This project uses the AtMega328P-PU as processor. Input is the DCC signal used in model railroading projects.
There are 16 MosFet driven outputs, separated from the AtMega by optocouplers (if you want separation).
A 5V power unit is integrated; it can get it's power from DCC or from a separate power supply.
There are a lot of LEDs in the circuit diagram, but you can leave a lot of them (and the ac...
> I got a lot of messages about the project, or the code, but the situation was I put the project on hold for a while, when waiting for parts to arrive, then modified multiple times without documenting etc... the project got finished working well, heat up quickly, but when I have time I will make a fully documented mark 2 version.
V.2 - added checking of the correct functioning of the controllers (ATmega and SPC-2). If one of them fails, the data in the output blocks is reset within 0.35s.
Makes the ancient PLC700 as Profibus DP slave for the modern controllers. Is inserted instead of the PLC700 Central units. Cabinet, external connections, I / O process control system remain unchanged. The data I/O refresh cycle...
This is an attempt to create your own version of the calculator on the ATMEGA8 chip.
The purpose of the conclusions of the microcontroller is seen in the circuit.
The handling of 20 keys is described on my blog - http://un7fgo.gengen.ru/?p=2127 (I apologize, only in Russian).
