Hey there!
I ordered the Espruino Pico via Kickstarter a while ago, without much thinking of what I could do with it. I make video games as a hobby, and now I want to use my pico to make a custom controller. Since this is my very first hardware project (except for some soldering back in school...), I have a few questions:
The Pico has 22 GPIO pins (9 Analogs inputs, 21 PWM, 2 Serial, 3 SPI, 3 I2C), does that mean I can use a total of 22 Buttons? Or are some of those not suitable for generic Buttons?
What if I wanted to add more Buttons? I thought about supporting up to four players, with one D-Pad (4 pins) and 4 Buttons per player, but then I would need at least 32 pins.
I plan to use some of these buttons and these Joysticks, which apparently behave just like a 4-button-entity.
Thanks in advance :)
