suspect-devices/circuitpython/stmhal/spi.c, branch 2.xCircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=2.x2017-08-13T12:52:33+00:00all: Raise exceptions via mp_raise_XXX2017-08-13T12:52:33+00:00Javier Candeirajavier@candeira.com2017-08-09T04:40:45+00:00urn:sha1:35a1fea90b2cae9d5cc8e9eab62ba4c67e8786db
- Changed: ValueError, TypeError, NotImplementedError
- OSError invocations unchanged, because the corresponding utility
function takes ints, not strings like the long form invocation.
- OverflowError, IndexError and RuntimeError etc. not changed for now
until we decide whether to add new utility functions.
all: Use the name MicroPython consistently in comments2017-07-31T08:35:40+00:00Alexander Steffendevel.20.webmeister@spamgourmet.com2017-06-30T07:22:17+00:00urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e
There were several different spellings of MicroPython present in comments,
when there should be only one.
stmhal: Make error messages more consistent across peripherals.2017-06-15T02:02:14+00:00Damien Georgedamien.p.george@gmail.com2017-06-15T02:02:14+00:00urn:sha1:2bf5a947b2b01f2be6c7b05707391dd09b240ad0stmhal: Convert all module and method tables to use MP_ROM macros.2017-05-06T07:03:40+00:00Damien Georgedamien.p.george@gmail.com2017-05-06T07:03:40+00:00urn:sha1:0986675451edbdcbe31d90ddacf8f6dc3327a4aestmhal/spi: Increase SPI transfer timeout, proportional to num bytes.2017-03-29T05:02:43+00:00Damien Georgedamien.p.george@gmail.com2017-03-29T05:02:43+00:00urn:sha1:22e2f4a0e896b185517186e5873d765fcd643351
With the existing timeout of 100ms the transfer would end prematurely if
the baudrate was low and the number of bytes to send was high. This patch
fixes the problem by making the timeout proportional to the number of bytes
that are being transferred.
stmhal/spi: Clean and/or invalidate D-cache before SPI DMA transfers.2017-03-28T01:54:01+00:00Damien Georgedamien.p.george@gmail.com2017-03-28T01:54:01+00:00urn:sha1:ff927cb106a6a74bd04f729bc0c1fded6955881f
On MCUs with a cache (eg F7) this must be done or else the SPI data that is
transferred is incorrect.
all: Consistently update signatures of .make_new and .call methods.2017-01-04T13:10:42+00:00Paul Sokolovskypfalcon@users.sourceforge.net2017-01-04T13:10:42+00:00urn:sha1:eac22e29a5844e5aa5c865c2e73900e6ef039ad6
Otherwise, they serve reoccurring source of copy-paste mistakes and
breaking nanbox build.
stmhal: Refactor to use extmod implementation of software SPI class.2016-12-08T02:58:10+00:00Damien Georgedamien.p.george@gmail.com2016-12-08T02:58:10+00:00urn:sha1:1b6d94bccdd95904a85e8aa689b0844ab55a61bf
This is a pure refactoring (and simplification) of code so that stmhal
uses the software SPI class provided in extmod, for the machine.SPI
implementation.
stmhal: Rename mp_hal_pin_set_af to _config_alt, to simplify alt config.2016-11-11T06:53:45+00:00Damien Georgedamien.p.george@gmail.com2016-11-11T06:53:45+00:00urn:sha1:1375c52772ad4f07d4bce40bfa114a0f2f0e6cfc
This way the caller doesn't need to initialise a big GPIO_InitTypeDef
struct, and HAL_GPIO_Init is no longer called.
stmhal: Refactor pin usage to use mp_hal_pin API.2016-10-18T03:34:08+00:00Damien Georgedamien.p.george@gmail.com2016-10-18T03:32:42+00:00urn:sha1:d49d81b1675b39c0c29c95b105edbbb7384f9314
