It’s also possible a chip like the CH375 could be used, taking the microcontroller out of the equation entirely.įrom classic breadboard builds to some impressively practical portable machines, we’ve seen our fair share of 6502 computers over the years. The use of shift registers could reduce the number of wires between the Arduino and VIA, which would be a start.

While the code could likely be tightened up, there’s obviously some improvements to be made in terms of the electrical interface. But as you can see in the video after the break, it’s at least functional. Then eleven more digital pins were connected to the computer, each one representing a state for the mouse and buttons, such as MOUSE_CLICK_RIGHT and MOUSE_LEFT_DOWN.Īdmittedly, says the mouse action is far from perfect. In the end, connected one of the digital pins from the Arduino to an interrupt pin on the computer’s W65C22 versatile interface adapter (VIA). There was plenty of code and examples that showed how you could read the mouse position and clicks from the Arduino, but still had to figure out a way to get that information into the 6502. The idea early on was to leverage existing Arduino libraries to connect with a standard USB mouse, specifically, the hardware would take the form of an Arduino Mega 2560 with a USB Host Shield. Code for mapping mouse movement to digital output. For example, take the lengths to which was willing to go in order to support standard USB mice on their 6502 machine. If you didn’t want to really get your hands dirty with the nuts and bolts of the thing, you wouldn’t have built it in the first place. When building your own homebrew computer, everything is a challenge.
