suspect-devices/circuitpython/cc3200/mods/pybi2c.c, branch 2.3.1 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=2.3.1 2017-08-21T11:34:23+00:00 all: Make static dicts use mp_rom_map_elem_t type and MP_ROM_xxx macros. 2017-08-21T11:34:23+00:00 Damien George damien.p.george@gmail.com 2017-08-21T11:34:23+00:00 urn:sha1:4ec803a42ae3080d4af959c7c2edf81e57f79377 all: Use the name MicroPython consistently in comments 2017-07-31T08:35:40+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-30T07:22:17+00:00 urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e There were several different spellings of MicroPython present in comments, when there should be only one. cc3200/mods/pybi2c: Make readfnom_mem_into/writeto_mem return None. 2017-04-18T05:31:08+00:00 Damien George damien.p.george@gmail.com 2017-04-18T05:31:08+00:00 urn:sha1:9d7c53734c5eee6b4fbcc18be59148bbdaf95a1d This aligns the I2C class to match the standard machine.I2C API. Note that this is a (small) breaking change to the existing cc3200 API. The original API just returned the size of the input buffer so there's no information lost by this change. To update scripts users should just use the size of the buffer passed to these functions to get the number of bytes that are read/written. cc3200/mods/pybi2c: Make machine.I2C constructor/init conform to HW API. 2017-04-18T03:16:05+00:00 Damien George damien.p.george@gmail.com 2017-04-18T03:16:05+00:00 urn:sha1:8f205c2c9bed1f3f167f2b0a5abba1e676a6aa01 This is a user-facing change to the cc3200's API, to make it conform to the new machine hardware API. The changes are: - change I2C constructor to: I2C(id=0, *, freq=100000, scl=None, sda=None) - change I2C init to: init(*, freq, scl, sda) - removal of machine.I2C.MASTER constant - I2C str/repr no longer prints I2C.MASTER To update existing code it should be enough to just remove the I2C.MASTER constant from contructor/init for I2C. cc3200/mods/pybi2c: Raise OSError if readfrom_mem fails to write addr. 2017-03-29T05:09:46+00:00 Damien George damien.p.george@gmail.com 2017-03-29T05:09:46+00:00 urn:sha1:6bfb344a808081aaaf883b7576699e05d9a86882 cc3200: When raising OSError's use MP_Exxx as arg instead of a string. 2017-02-22T01:58:11+00:00 Damien George damien.p.george@gmail.com 2017-02-22T01:36:23+00:00 urn:sha1:22a6344ebe032e9e66024614ecbe7d9608fa9288 all: Consistently update signatures of .make_new and .call methods. 2017-01-04T13:10:42+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-01-04T13:10:42+00:00 urn:sha1:eac22e29a5844e5aa5c865c2e73900e6ef039ad6 Otherwise, they serve reoccurring source of copy-paste mistakes and breaking nanbox build. cc3200: Use mp_raise_XXX helper functions to reduce code size. 2016-10-17T22:53:43+00:00 Damien George damien.p.george@gmail.com 2016-10-17T22:53:43+00:00 urn:sha1:50ddaafa6acf5fbbe6f98e64fd5744a9a8347aff Reduces code size by 632 bytes. stmhal, cc3200: Change i2c.scan() method to scan addresses 0x08-0x77. 2016-05-02T10:15:36+00:00 Damien George damien.p.george@gmail.com 2016-05-02T10:15:36+00:00 urn:sha1:70ff7350e7ff369ab81d1f55e6645a5828928385 A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx are reserved. The scan() method is changed to reflect this, along with the docs. cc3200: Improve robustness of the I2C driver. 2016-02-21T20:41:06+00:00 danicampora daniel@wipy.io 2016-02-12T19:17:15+00:00 urn:sha1:562bcffd3aa9e9e1226389e658c6d5d0ac007add When scanning for devices, try reading then writing. Increase the timeout of the transactions from 10 to 20 ms.
