CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=esp-extra-scripts 2016-05-05T13:51:20+00:00 2016-05-05T13:51:20+00:00 Tobias Badertscher python@baerospace.ch 2016-03-22T10:28:35+00:00 urn:sha1:e64032d6fdeb079de2ace20b64899d1ceb6754f1 The main thing is to change the DMA code in a way that the structure DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4) is no longer used outside of dma.c, as this structure only exists for the F4 series. Therefore I introduced a new structure (dma_descr_t) which handles all DMA specific stuff for configuration. Further the periphery (spi, i2c, sdcard, dac) does not need to know the internals of the dma. 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. 2016-02-11T05:20:14+00:00 Dave Hylands dhylands@gmail.com 2016-02-11T05:20:14+00:00 urn:sha1:7bb501ef9f724e9ecd209d1fa46b640214928d2a mp_hal_gpio_set_af will search for a given function and unit and set the alternate function to the alternate function index found. 2016-01-11T00:49:27+00:00 Damien George damien.p.george@gmail.com 2016-01-03T15:55:55+00:00 urn:sha1:5b3f0b7f39bd67cc9182993c288f09f67a0890df The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t. 2015-12-02T22:55:57+00:00 Dave Hylands dhylands@gmail.com 2015-12-01T08:42:47+00:00 urn:sha1:0077958ad0d278c87620ee8ead9a9aea80f1663d 2015-11-14T14:14:08+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-11-14T14:13:58+00:00 urn:sha1:16d42368a64cca3927ceac26b33015f73d501427 In new hardware API, these classes implement master modes of interfaces, and "mode" parameter is not accepted. Trying to implement new HW API in terms of older pyb module leaves variuos corner cases: In new HW API, I2C(1) means "I2C #1 in master mode" (? depends on interpretation), while in old API, it means "I2C #1, with no settings changes". For I2C class, it's easy to make mode optional, because that's last positional param, but for SPI, there's "baudrate" after it (which is inconsistent with I2C, which requires "baudrate" to be kwonly-arg). 2015-10-31T16:14:30+00:00 Damien George damien.p.george@gmail.com 2015-10-30T23:03:58+00:00 urn:sha1:731f359292c0e2630873df1a19c5baac7287024f py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations. 2015-08-05T22:38:24+00:00 Dave Hylands dhylands@gmail.com 2015-08-04T06:04:57+00:00 urn:sha1:34fe5a30c6b9ec4ff5d9b10ef9b2e39ec5fd778f 2015-08-02T23:14:48+00:00 Damien George damien.p.george@gmail.com 2015-08-02T23:05:16+00:00 urn:sha1:0851751615580d02bd6f841e13651923f05fde59 Extracted GPIO clock enable logic into mp_hal_gpio_clock_enable and called from anyplace which might need to use GPIO functions on ports other than A-D.
