+ | After I found that the ISP programming pins are wrong, I successfully programmed the first digital controller. The clock simulation is now up and running. Next RAM and ROM simulation. That will be a software task. It is fun to work digital again! | ||

+ | I designed a testing board with a SN754410 H-Bridge driver for testing. I can test 4 outputs and 4 inputs per testing board easily with an Arduino now. The SN754410 is still in delivery and will get assembled later. [[https:// | ||

- | ==== Logo ==== | + | === 2020-08-01 |
- | This board is made of **120** LEDs just for this board. It is the projectlogo with through-pcb illumination. | + | My automated long term test is up and running. 1000 test-iterations per bit. Tuned the loading speed of the C (adding 100 Ohms), added diodes (1N4007) and tuned the holding voltage of the relais better by adding 100 Ohms. |

+ | Fixed the "4-Bit Register rev2" board. The board is fully functional but has some drawbacks. You need to scratch away 8 traces on the board and solder 8 short wires on it. | ||

+ | | ||
+ | * Numbering of the LEDs would be helpful. Fixed in rev3. | ||

+ | === 2020-06-18 === | ||
+ | The PCBs for the 4Bit Register and the Logo did arrive. I assembled them successfully. I'm now waiting for the new Relays HK19F for the final test of the registers. In the Logo-PCB there was a little mistake but I succeed fixing it by scraping away two traces. | ||
