Detecting SPI signal collisions

[jimrh]

Greetings!

Everyone who has been paying attention knows that I have been trying to get various display modules working with the GoPiGo-3 with indifferent success, primarily due to the fact that I’ve been sending in boys to do men’s jobs.

I’ve decided it’s time to get REAL tools to do the job.

1. A decent temperature controlled, calibratable, ESD-safe soldering station.

(I’m getting tired of lifting traces every time I try to do something! )

2. A reasonably professional-grade logic analyzer.

The logic analyzer supports fun stuff like serial UART, CAN buss, i²c, SPI, etc. along with just plain-'ole signal analysis.

I am also planning on getting a more professional grade desoldering station for surface mount components.

Things have been crazy and I haven’t had the time to spend on Charlie and Charlene, but I’m getting there.

All the right tools if your GoPiGo3 suddenly stops detecting/communicating with I2C sensors, like Humble Dave’s Pi5 4GB board. He had to be reincarnated as Kilted-Dave on a “lowly” Pi4 and throw away his ROS 2 vision mapping and navigating aspirations. (“Dave” code requires I2C to access his current sensor.)
