suspect-devices/circuitpython/zephyr/machine_pin.c, branch 5.3.0

ports: Make new ports/ sub-directory and move all ports there.

2017-09-06T03:40:51+00:00

This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.

all: Convert remaining "mp_uint_t n_args" to "size_t n_args".

2017-08-30T00:59:58+00:00

This is to have consistency across the whole repository.

all: Make static dicts use mp_rom_map_elem_t type and MP_ROM_xxx macros.

2017-08-21T11:34:23+00:00

all: Use the name MicroPython consistently in comments

2017-07-31T08:35:40+00:00

There were several different spellings of MicroPython present in comments, when there should be only one.

zephyr/machine_pin: Use native Zephyr types for Zephyr API calls.

2017-06-10T16:40:31+00:00

In 1.8, Zephyr made a controversial change of dumping C99 stdint types and switching to its own types.

esp8266, stmhal, zephyr: Rename machine.Pin high/low methods to on/off.

2017-05-21T14:44:58+00:00

For consistent Pin/Signal class hierarchy. With it, Signal is a proper (while still ducktyped) subclass of a Pin, and any (direct) usage of Pin can be replace with Signal. As stmhal's class is reused both as machine.Pin and legacy pyb.Pin, high/low methods actually retained there.

zephyr/machine_pin: Implement pin protocol for machine.Signal support.

2017-04-08T11:27:36+00:00

zephyr: Initial implementation of machine.Pin.

2016-10-26T21:47:26+00:00

The integration with Zephyr is fairly clean but as MicroPython Hardware API requires pin ID to be a single value, but Zephyr operates GPIO in terms of ports and pins, not just pins, a "hierarchical" ID is required, using tuple of (port, pin). Port is a string, effectively a device name of a GPIO port, per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer number of pin with the port (supposed to be in range 0-31). Example of pin initialization: pin = Pin(("GPIO_1", 21), Pin.OUT) (an LED on FRDM-K64F's Port B, Pin 21). There is support for in/out pins and pull up/pull down but currently there is no interrupt support. Signed-off-by: Daniel Thompson Signed-off-by: Vincenzo Frascino Signed-off-by: Paul Sokolovsky
