That's what pausing inside reconstruct fixes. So that the "right timer" can be chosen, `timer_allocate` now gets the `self` pointer. It's guaranteed at this point that the pin information is accurate, so you can e.g., find a PWM unit related to the pins themselves. This required touching each port to add the parameter even though it's unused everywhere but raspberrypi. 2021-01-26T15:19:44+00:00 Jeff Epler jepler@gmail.com 2021-01-26T15:19:44+00:00 urn:sha1:51f054440516d21bd2e8d07a3e6f1f8e3acfbd55 2021-01-25T17:40:14+00:00 Kamil Tomaszewski kamil.tomaszewski@sony.com 2021-01-25T17:05:48+00:00 urn:sha1:30a1c52e757622969dedf03c988c59a35b4a1302 2021-01-21T19:33:13+00:00 Scott Shawcroft scott@tannewt.org 2021-01-21T19:33:13+00:00 urn:sha1:b73b30ff9f890ffd4e38d4c7ce7bcef7c92c1afb 2021-01-21T03:16:56+00:00 Scott Shawcroft scott@tannewt.org 2021-01-21T00:47:18+00:00 urn:sha1:733094aead6e84b42da54655b2b0a5d0dbd1a503 The RP2040 is new microcontroller from Raspberry Pi that features two Cortex M0s and eight PIO state machines that are good for crunching lots of data. It has 264k RAM and a built in UF2 bootloader too.

The main benefit of the update is to fix problems encountered on Windows, as the old ref of uzlib had filenames with embedded colons; this has been fixed upstream. uzlib seems to have been reabsed since the version that we took; this doesn't really matter to us.
