I’ve put my Pi3B+ in the cupboard under the stairs.
Scroll Phat HD is remote from the Pi, on about a metre or so of wiring.
Scroll Phat HD runs, for a while, until I turn the cupboard light on or off, when Scroll Phat crashes.
Error on terminal shows:
Traceback (most recent call last): File "scrolling1.py", line 46, in <module> scrollphathd.show() File "/usr/lib/python2.7/dist-packages/scrollphathd/is31fl3731.py", line 594, in show self.i2c.write_i2c_block_data(self.address, _COLOR_OFFSET + offset, chunk) IOError: [Errno 121] Remote I/O error ------------------ (program exited with code: 1) Press return to continue
Runs OK again when .py file is retried.
Pi is on a a standard domestic ring-main circuit, flu-tube is on standard domestic lighting circuit.
Any ideas on why a flourescent light would cause Scroll Phat HD to stop?
Any what can I do to prevent it happening?
