Also updated the example pin names to not use RX and TX. 2017-12-13T18:12:49+00:00 Dan Halbert halbert@halwitz.org 2017-12-13T18:12:49+00:00 urn:sha1:43650b689674a18b95d520921d10a91b67f64c84 Changes: * New faster filter loop, by @ladyada. New filter coefficients as well. * Turn on microphone clock when PDMIn object is created, and run it all the time, so the user code doesn't have to wait for microphone startup, which can be 10ms or even 100ms. * Wait for microphone startup when PDMIn is first created, based on new optional parameter microphone_startup in seconds (takes a float). * record() returns number of samples actually recorded, so you can see if it's not keeping up. * Fix buffer overflow errors when buffer size was not a multiple of 16 or something like that. * Tweak a few peripheral settings. * Minimum sampling frequency is now 16kHZ or so, because 8kHz runs microphone at only 0.5MHz, which is too slow for many mics. Note: I tried 128x oversampling instead of 64x, but the code cannot keep up at 24kHz or above sampling. 128x would reduce the high-frequency noise by 6db. 2017-12-06T00:04:47+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-12-06T00:04:47+00:00 urn:sha1:a91e1cb68271ae2acc3d65ece1d781d6077e4138 2017-12-05T22:50:58+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-12-05T22:50:58+00:00 urn:sha1:b4d36990479888a0be503383367fbd1bd9b6976b This allows one to configure how a subsequent reset will behave and also trigger a reset.

It provides support for fast rendering of tile grids and sprites on SPI-based RGB displays.
