8 bit computer, solution for the microcode As I mentioned in this post, I was looking for a solution to program a couple of EEPROMs that are going to hold the microcode for my 8 bit computer. Using an Arduino
Robotics on the work floor I came across a nice video about the influence of robots on the work floor of warehouses.
8 bit computer, program counter and reset I’m busy transitioning my 8 bit computer from the breadboards I built it on to experimental PCB’s. They will be on a bus print. Here’s the first video:
EEPROM Programmer For the more complex decoding on my 8 bit computer like for example the Control Unit I will use an EEPROM, not some elaborate complex circuitry. For this I must be able to program an EEPROM. On his Youtube channel
New power supplies Welcome to my two new DC LAB Power Supplies: the Velleman LABS3005. They can each supply 0-30 Volts (adjustable) and 0-5 Amp’s (also adjustable) power, with a ripple voltage of 2mV and a ripple current of 3mA.
Raspberry Pi controlled elevator movie Finally, here it is, the movie explaining my Raspberry Pi controlled elevator. Have a look:
I2C Relay driver card and Arduino Today, I coupled my Relay card to the Arduino UNO through the I2C interface. There’s an ADAFRUIT Arduino library available for the MCP23017 IO expander chip. I used a little test-program in the Youtube movie.
Working with both Arduino’s Okay, to work now. I’ve connected the pre-built VMA100 to my MacBook Pro to be able to program it. The separate ATmega328 chip from the barebone kit has been programmed as well. Power for both chips comes
Programming ATmega328 using the UNO Using these instructions, I managed to burn a boot loader on my ATmega328 chip from the barebone kit. Second step, I took out the UNO chip and slapped my barebone kit together on my breadboard
Aduino UNO Barebone Kit Today I ordered an Arduino UNO barebone kit at my “house supplier”, Okaphone in Groningen, the Netherlands. The specs from the webshop, translated: Voltage 5 V Build your own Arduino compatible computer on a PCB or breadboard. kit contains AtMega328 (Uno
