(#258) 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. atmel-samd: Add a safe mode which detects hard faults and reboots without running user code again. 2017-05-15T22:29:04+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-05-13T16:17:43+00:00 urn:sha1:974847ac8d9fc2f64b43953da1731612840bb171 atmel-samd: Use link time optimization to reduce code size of builds which 2017-02-26T00:00:33+00:00 Scott Shawcroft scott.shawcroft@gmail.com 2017-02-25T11:19:33+00:00 urn:sha1:062fac1d43d42b35e0ecdaaec124c29b65db7c68 share space with the file system. "Express" builds with SPI flash crash the compiler for some reason so its currently disabled for them. Add frequency changing support to PWMOut. 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. atmel-samd: Add Micro Trace Buffer support to the debug build. 2016-10-04T23:13:33+00:00 Scott Shawcroft scott@chickadee.tech 2016-10-04T23:13:33+00:00 urn:sha1:1fa4c20c27264e55b3442fe49bee2078a4516fa6 The Micro Trace Buffer records the history of the pc and can be used to debug hard faults even when the stack trace is useless. Add support for REPL on Arduino Zero through EDBG via UART. 2016-08-23T23:47:53+00:00 Scott Shawcroft scott@chickadee.tech 2016-08-23T23:47:53+00:00 urn:sha1:9485634d41369e896a0ef0f7504f2195b68679e7 Blinking the LED works. Clocks should be set up correctly. 2016-08-23T06:53:11+00:00 Scott Shawcroft scott@chickadee.tech 2016-08-23T06:48:09+00:00 urn:sha1:8f26d181c30f8d371a900355a6f9edfab29c8fbe Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.
