Detecting SPI signal collisions

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! :face_with_symbols_over_mouth:)

  1. 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.)

I just reincarnated that “no I2C Pi5” board with a Raspberry Pi5 M.2 HAT+ and an official Raspberry Pi NVMe 256GB SSD as “RPi5Desk”. Needed a 16GB RPi 5 and an SSD for playing with OpenMind’s OM1 “robot mind”, but I’m not willing to invest in another RPi that will end up sitting on my desk unused.
