Using Rpi + Arduino with latest image, no success
Im using Rp 3 B+ with Arduino and using circuit or pins as defined in Fabscan pi Shield(from ur github). But it checking the firmware of arduino but not flashing. In log it says, Current Firmware: None, No Arduino or Compatible device found.
I can ping to pi and server also starts but can't reach to the Interface through IP.
Another question i want to ask, can i use simple white LED instead of WS2812 ? i will attach a switch to turn it on and off
Sorry but it is not that easy. Because the LED's are also controlled by the FabScanPi HAT. The scanner needs to be able to turn it on an off for different scan processes. During the plain object scan (geometry) there is no light. But while the texture scan is performed the lights are turned on. When the lights are turned on during the object scan the scan process wouldn't work.
If you really want to use a normal led you also need to connect the LED to one of the HATS's free Pin's (there are a lot e.g. an unused Motor port) and finally you need to add this option to the firmware to make it controllable. At the end the FabScanPi-Server code will need a small adjustment for controlling this pin ( in the led driver ).
