After all, he wants to build a robot, but without some basic knowledge about programming, he won’t get very far …. The processreadfromsd takes care of the output.This is the first part of a series of articles I’ve written to get beginners started with Arduino Programming in the programming language C, which I’ve written with the intend to teach my 13 year old nephew Bram Knuit (and his 10 year old brother Max Knuit) to get started with the Arduino. I adjusted the VGA pinout to free the 2 SPI pins for the SD, that the original setup was using and this is my pinout displa圜ontroller.begin(GPIO_NUM_21, GPIO_NUM_22, GPIO_NUM_4, GPIO_NUM_17, GPIO_NUM_15) The PS2 mouse and keyboard are left on their original pinout. The SD CONFIG #define SD_CONFIG SdSpiConfig(SS, SHARED_SPI, SD_SCK_MHZ(16)) Without this I could not get the code running, but with other SD or breakout this might have to adjust this. When it comes to the code, I took the original AZIP and added the fabgl on top of it, I do want to point out a few thigs You can use this schematics to set it up And last and not least is the sound, which here I used a cut cable for. You can use the schematics on the site, to help you with the PS2 connector pin out. I use a logic level convertor, since the PS2 is 5V and the esp32 is 3.3V. I used PS2 with Arduino in the past, so I had a pair of female connectors with pin breakout ready. I used this schematics to figure out the pin out I used the 8 color setup, with one pin for each color, connected via a 270Ohm resistor. I took a VGA cable cut off one end and wired it up to a breadboard friendly connector. I was thrilled when I first got to play it on the new setup. Now since I have made several attempts in the past, some of the code adjustments were ready for me, just had to copy them from old projects I kept (lucky me). If you want to try it out The next step, which forced me to make more adjustments, was to make it work on the ESP32. I forked the original project and spend 2 days in finding the right combination of libraries and settings to get the code to compile and work. Now all that retro, brought Zork back to my mind and then It clicked – I can finally get that project I was dreaming of to work. Getting the space invaders example working on the VGA screen with sound was surprisingly simple and defiantly it was fun playing. Allowing you to basically turn the ESP32 into a small computer, with SD, PS2 mouse and keyboard, sound engine and the cherry on top – VGA output! Fast forward to few weeks back, I came across another amazing work, which is the fabGL library for ESP32. Adding a PS2 keyboard was easy, but finding a proper output, and get it all to work together was too complicated, and I just stopped trying at some point. So I made several attempts to make a standalone unit. The thing was, that you had to connect it to a computer and play over the serial monitor. This project actually started 9 years ago, when I came across this post on the Arduino forum The user Louis Davis did an amazing work of taking an existing Z- interpreter and make it work on an Arduino mega with SD card. It used Z-machine instructions as the game data, there for allowing any machine with Z-interpreter to play. There is no graphics, and you type in your commands.
