CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=main 2017-09-23T01:05:51+00:00 2017-09-23T01:05:51+00:00 Scott Shawcroft scott@tannewt.org 2017-09-23T01:05:51+00:00 urn:sha1:6839fff31303463d5c7942387fa498895edf1abf * atmel-samd: Remove ASF3. This will break builds. * atmel-samd: Add ASF4 for the SAMD21 and SAMD51. * Introduce the supervisor concept to facilitate porting. The supervisor is the code which runs individual MicroPython VMs. By splitting it out we make it more consistent and easier to find. This also adds very basic SAMD21 and SAMD51 support using the supervisor. Only the REPL currently works. This begins the work for #178. 2017-07-28T19:12:38+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-05-24T17:43:32+00:00 urn:sha1:557ceded00de20d2070e1397d3dec322f753d1e6 microphones. 2017-05-01T20:10:03+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-04-21T21:43:03+00:00 urn:sha1:58b9789d0c824c665db744ef3653d6304e908bc0 2017-01-30T23:02:01+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-01-27T02:05:46+00:00 urn:sha1:e3f9ee839afb5a369779a30a96214c929e76911e You can either set it once up front, or set variable_frequency on custruction to indicate that the frequency must be able to change. This informs whether a timer can be shared amongst pins. This also adds persistent clock calibration on atmel-samd. Once the device has synced its clock frequency over USB it will remember that config value until USB is used again. This helps ensure the clock frequency is similar on and off USB. Lastly, this also corrects time.sleep() when on USB by correcting the tick counter. 2016-12-19T21:03:50+00:00 Sebastian Plamauer oeplse@gmail.com 2016-10-31T19:18:39+00:00 urn:sha1:1598e44231a9ea2dbf20f487fcd05ded90e80d9a 2016-11-07T20:37:38+00:00 Scott Shawcroft scott@chickadee.tech 2016-11-07T20:37:38+00:00 urn:sha1:acc4fe4d7db647aa2f2da3abd5e9a655da7124ec 2016-10-05T18:07:29+00:00 Scott Shawcroft scott@chickadee.tech 2016-10-05T18:07:29+00:00 urn:sha1:7e08347d5c4dc0d250eb473f08469cef702fe4f9 Be careful to not use the flash file system while using mass storage because both pieces of code attempting to change the fs can corrupt it. 2016-10-04T23:01:14+00:00 Scott Shawcroft scott@chickadee.tech 2016-10-04T23:01:14+00:00 urn:sha1:98458c56cc8801dce62866199541bcfcdb6ae26a 2016-09-03T00:00:30+00:00 Scott Shawcroft scott@chickadee.tech 2016-09-03T00:00:30+00:00 urn:sha1:09be96a6aa56734f13a7a7b7c5c1c5f29f014364 2016-08-30T20:10:52+00:00 Scott Shawcroft scott@chickadee.tech 2016-08-30T20:10:52+00:00 urn:sha1:ccb309bd5c0b283ea847b18621038bf5ef817f38
