I’ve got a Qwiic Twist DEV-15083 hooked up to a RedBoard Artemis via the Qwiic connector. It appears to have gone Tango Uniform after exhibiting some weird behavior. I want to make sure I’ve diagnosed this correctly, and not missed something I could do to recover it?
I also have an LCD-14074 connected to the same bus via a Qwiic breadboard cable (so the LCD is at the end of the chain, after the Twist).
At the moment, if I detach the LCD completely, and run any of the Twist examples, the Twist powers on with the LEDs in the last color state the Twist had before it seems to have failed (which is 0,255,0 - so, solid green), and nothing else happens. The encoder doesn’t update when twisted, nor do I get a click or press state out of it. If I run an I2C scanner with just the Twist connected, the scanner finds a device at every address.
To double check the scanner, I also ran it with no devices on the bus (scanner correctly reports 0 devices), and with the LCD on the bus (correctly reports a device at 0x72).
I tried a new Qwiic cable to the Twist with no luck. I also shorted the RST pin to ground for 10 seconds or so (causes the RGB LED to turn off), with no luck, either. I tried the reset pin a couple different ways (shorted upon power on, shorted while power was already applied, shorted with power supplied then remove power before removing the short) - I don’t know if there’s a specific order of operations there to properly reset the ATtiny84 chip?
Thanks!
Dave
