Phil Howard	7375a208c6	make GAMMA common ... Moves the 256 entry GAMMA table into pimoroni_common. Should probably be added into a library so MicroPython is built with only one instance of the table.	2021-09-13 17:40:51 +01:00

Phil Howard	b5c7add90d	APA102: Extra clocks to flush pixels ... This covers an edge case where pixels are updated intermittently - such as the once that happens when clearing before a Python soft reset. Under normal circumstances users should `start` the LED strip and allow it to continuously update.	2021-08-26 18:14:39 +01:00
Phil Howard	e283d460d4	Make ws2812 and apa102 responsibly only for their own buffers ... This fixes a bug where delete[] would be called on a bytearray buffer allocated by MicroPython on gc_heap.	2021-08-25 22:00:16 +01:00
Phil Howard	53429e0c6f	Do not pio_sm_unclaim for MicroPython ... Adds an ifdef guard around `pio_sm_unclaim` that prevents it being called when MicroPython cleans up/finalizes classes. For some reason this appeared to be causing a hardfault.	2021-08-25 16:06:51 +01:00
ZodiusInfuser	823729dc24	Move apa and ws PIO into drivers so they can be easily used with more boards	2021-08-19 13:40:46 +01:00
