I recently had need to rebuild one of my Raspberry Pis. It’s a Raspberry Pi 3 Model B running Raspian Buster. I reinstalled my pi-topPULSE, followed the installation instructions but when I try and run the demo code I get the following error:
sudo python3 led-demo.py
[19:24:58.502860 I] Error: pi-topPULSE is not initialised. Call ptpulse.configuration.initialise() ptpulse.configuration.enable_device()
Any help/ideas as to what the root cause may be, and next steps, would be appreciated.
