- Simultaneous joystick 3-axis protocol

> cross-posted from: https://lemmy.world/post/10852531 > > > Working on a joystick. Seems like any protocol I use to read from peripherals is going to be bottlenecked by having just one input. My microcontroller might have multiple ADCs, but there's just one processor stepping through them. Same for spi, or i2c, or uart.

To sample each axis we're down to only 4.5k samples per second.

- Need help making a timer
Hello!
For a project I need to make a four-digit timer that counts up. I think I can figure out the counting part myself, it is just the display part I need help with.
We are using four separate seven segment displays and an Arduino Mega 2560. The code currently looks like this: (I had it written over multiple lines, but the Lemmy preview just makes one big block of text from it so sorry for that)
void Display1() // Display a 1 { digitalWrite(1, LOW); digitalWrite(2, LOW); digitalWrite(4, HIGH); digitalWrite(6, HIGH); digitalWrite(7, LOW); digitalWrite(9, LOW); digitalWrite(10, LOW); }This function is for writing a one, but I have written one for all ten numbers already. The problem is that this only works for the first display. Does anyone know how I can edit this code to make four seven segment displays work together, and make it display full numbers like 8732 for example?
Thank you!

Tbh much of the content is already on the official documentation, but it’s more precise and directed in the book.
While the content itself is spot on, some of the code examples does not work/compile on the current Arduino ide.
