CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=6.2.x 2021-02-12T14:25:15+00:00 2021-02-12T14:25:15+00:00 Jeff Epler jepler@gmail.com 2021-02-11T22:37:34+00:00 urn:sha1:ff1942cff68a4e192f984a14a83b59800186e45a Also found a race condition between timer_disable and redraw, which would happen if I debugger-paused inside common_hal_rgbmatrix_timer_disable or put a delay or print inside it. 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. 2021-01-26T20:33:48+00:00 Jeff Epler jepler@gmail.com 2021-01-26T20:33:48+00:00 urn:sha1:368977fb906e6561bd67977a47dc0b415547cc33 * Introduce explicit serpentine: bool argument instead of using negative numbers (thanks, ghost of @tannewt sitting on one shoulder) * Fix several calculations of height Testing performed (matrixportal): * set up a serpentine 64x64 virtual display with 2 64x32 tiles * tried all 4 rotations * looked at output of REPL 2021-01-26T15:19:44+00:00 Jeff Epler jepler@gmail.com 2021-01-26T15:19:44+00:00 urn:sha1:51f054440516d21bd2e8d07a3e6f1f8e3acfbd55 2020-10-10T19:30:37+00:00 Jeff Epler jepler@gmail.com 2020-10-10T19:30:37+00:00 urn:sha1:5e38bb98cbcc2d1ab607b19d11e628def4f48f4c this is compile-tested on stm32f405 feather matrixportal nrf52840 feather but not actually tested-tested. 2020-09-02T18:34:16+00:00 Jeff Epler jepler@unpythonic.net 2020-09-02T18:34:16+00:00 urn:sha1:17a5a85528525352ec1821127fafec2acb239196 2020-04-17T23:43:57+00:00 Jeff Epler jepler@gmail.com 2020-04-15T16:22:16+00:00 urn:sha1:3d6258f63dce84519704251b86a16c832958c8a6 This is a quick rename, it changes the user-facing names but not the internal names of things.
