CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=main 2021-03-31T14:40:48+00:00 2021-03-31T14:40:48+00:00 Jeff Epler jepler@gmail.com 2021-03-31T14:40:26+00:00 urn:sha1:cce8b2be07b5640026d7ef06d1421c217fe6a5d4 This allows more options to be overridden to 0 in an mpconfigboard.mk. Improved: * FRAMEBUFFERIO, FULL_BUILD, BITOPS, PWMIO, RGBMATRIX, OTARYIO, PULSEIO, WATCHDOG Still problematic (pull requests welcome): * RP2PIO & NEOPIXEL_WRITE, possibly only if a status neopixel is defined * BITBANGIO, possibly only if BUSIO is enabled * RTC Incidentally, with RP2PIO & NEOPIXEL_WRITE, BITBANGIO, and RTC re-enabled I get ``` 323956 bytes used, 720524 bytes free in flash firmware space out of 1044480 bytes (1020.0kB). 12072 bytes used, 250072 bytes free in ram for stack and heap out of 262144 bytes (256.0kB). ``` Closes #4515 2021-03-18T23:55:42+00:00 Scott Shawcroft scott@tannewt.org 2021-03-04T21:12:24+00:00 urn:sha1:5d2b60cbf69c99abd6984c298d4f052514221177 This switches stage2 to C and uses Jinja to change the C code based on flash settings from https://github.com/adafruit/nvm.toml. It produces the fastest settings for the given set of external flashes. Flash size is no longer hard coded so switching flashes with similar capabilities but different sizes should *just work*. This PR also places "ITCM" code in RAM to save the XIP cache for code execution. Further optimization is possible. A blink code.py still requires a number of flash fetches every blink.

However, it does work for some limited situations. 2021-03-09T05:28:21+00:00 DavePutz dwputz@gmail.com 2021-03-09T05:28:21+00:00 urn:sha1:6f4510d7aaf0a9182fd815f582d272de2f7611cc 2021-03-05T18:59:55+00:00 Jeff Epler jepler@gmail.com 2021-03-05T18:59:55+00:00 urn:sha1:cd1f19020fefd024c4aeef6a26ea61a11c26ab27 2021-03-05T16:31:29+00:00 Jeff Epler jepler@unpythonic.net 2021-03-05T15:00:03+00:00 urn:sha1:2ae1e7de61485bc9167996a63c32bf7b14c4c80c Any two consecutive pins can be used for an IncrementalEncoder Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out. Performed filesystem operations at the same time to stress test it.
