The only other changes in protomatter were one formatting change in the core, plus several Arduino sketches. So this should make no practical difference for CPy. 2020-09-01T15:55:45+00:00 Jeff Epler jepler@gmail.com 2020-08-28T16:17:07+00:00 urn:sha1:2f120c70eee692b8e036f8f0778af2b723e1f0e7 e.g., allocating a 192x32x6bpp matrix would be enough to trigger this reliably on a Metro M4 Express using the "memory hogging" layout. Allocating 64x32x6bpp could trigger it, but somewhat unreliably. There are several things going on here: * we make the failing call with interrupts off * we were throwing an exception with interrupts off * protomatter failed badly in _PM_free when it was partially-initialized Incorporate the fix from protomatter, switch to a non-throwing malloc variant, and ensure that interrupts get turned back on. This decreases the quality of the MemoryError (it cannot report the size of the failed allocation) but allows CircuitPython to survive, rather than faulting. 2020-07-16T16:08:40+00:00 Lucian Copeland hierophect@gmail.com 2020-07-16T15:12:53+00:00 urn:sha1:cdfc3a2d37771b67f82ab810ebfefcbb9cd6a14e 2020-05-07T23:32:50+00:00 Jeff Epler jepler@gmail.com 2020-05-07T19:44:08+00:00 urn:sha1:182ae10080d85adc34d7865c9b8cccf4b3d2f89c 2020-04-30T13:58:58+00:00 Jeff Epler jepler@gmail.com 2020-04-29T16:27:43+00:00 urn:sha1:e5be728c1c8a3a455b7095c9dab9e758c5016191 Testing performed: on stm32f405 feather, all pins change in plausible ways on a logic probe. Didn't actually drive a display yet. 2020-04-14T23:24:58+00:00 Jeff Epler jepler@gmail.com 2020-04-01T16:57:52+00:00 urn:sha1:1d8a073c05c36133e02d839ed187b9d7abf24d79 2020-04-14T23:24:54+00:00 Jeff Epler jepler@gmail.com 2020-03-10T18:12:01+00:00 urn:sha1:09dc46a98480350b157636ffff8b89470f595f6e
