suspect-devices/circuitpython/esp8266/modpyb.h, branch esp-extra-scriptsCircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=esp-extra-scripts2016-04-28T11:23:55+00:00esp8266: Move pyb.info() function to esp module and remove pyb module.2016-04-28T11:23:55+00:00Damien Georgedamien.p.george@gmail.com2016-04-28T11:23:55+00:00urn:sha1:a6aa35af09584bdf5d52275e0d9703ca4fec4231
All functionality of the pyb module is available in other modules, like
time, machine and os. The only outstanding function, info(), is
(temporarily) moved to the esp module and the pyb module is removed.
esp8266: Convert mp_hal_pin_obj_t from pin ptr to simple integer.2016-04-22T09:04:12+00:00Damien Georgedamien.p.george@gmail.com2016-04-22T09:04:12+00:00urn:sha1:a2d5d84ecca175fbfbf42e892d6376efd08758eb
Most pin I/O can be done just knowing the pin number as a simple
integer, and it's more efficient this way (code size, speed) because it
doesn't require a memory lookup to get the pin id from the pin object.
If the full pin object is needed then it can be easily looked up in the
pin table.
esp8266: Add hard IRQ callbacks for pin change on GPIO0-15.2016-04-14T11:44:26+00:00Damien Georgedamien.p.george@gmail.com2016-04-14T10:15:43+00:00urn:sha1:674bf1bc81ab358d167965f06e5c51f86027b050esp8266: Remove pin_id field from C pin object.2016-04-14T11:43:25+00:00Damien Georgedamien.p.george@gmail.com2016-04-13T21:38:44+00:00urn:sha1:a9a732af1fcd45c27aff731901e347d0ed82a888
This field is the same as phys_port and not needed.
esp8266: Protect modpyb.h header file from multiple inclusions.2016-04-12T13:06:54+00:00Damien Georgedamien.p.george@gmail.com2016-04-12T12:53:04+00:00urn:sha1:1a65ff1b72f4cccecc797902d9713bce57b17588
Also include py/obj.h so the header is self contained.
esp8266: Add initial implementation of machine.UART.2016-04-06T16:45:52+00:00Damien Georgedamien.p.george@gmail.com2016-04-06T16:45:52+00:00urn:sha1:1a0a323ca8daadb30e5ed3d58bc7e8e8e5a95629
Currently UART(0) and UART(1) are exposed and only uart.write works.
esp8266: Add PWM support.2016-03-25T22:32:37+00:00Damien Georgedamien.p.george@gmail.com2016-03-02T13:37:27+00:00urn:sha1:632d8efa0552a1dfb2615d29afc727e339b72574
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.
8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.
Usage:
import machine
pwm0 = machine.PWM(machine.Pin(0))
pwm0.freq(1000)
pwm0.duty(500)
Frequency is shared (ie the same) for all channels. Frequency is
between 1 and 1000. Duty is between 0 and 1023.
esp8266: Implement software SPI class.2016-03-25T21:28:13+00:00Damien Georgedamien.p.george@gmail.com2016-03-01T22:53:23+00:00urn:sha1:82b95f625ebedacfaf7a8809bb5d71e9bd19fb7d
Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins. Only supports MSB output at the moment.
esp8266: Add basic I2C driver, with init and writeto methods.2016-03-24T09:17:17+00:00Damien Georgedamien.p.george@gmail.com2016-02-11T12:43:41+00:00urn:sha1:dd32f02cc3c5d23acd033fda83e968b1eff3d42f
Tested and working with SSD1306 I2C display.
esp8266: Expose pin object as a public structure for use as C pin API.2016-03-24T09:07:41+00:00Damien Georgedamien.p.george@gmail.com2016-02-11T11:41:58+00:00urn:sha1:7059c8c23c85f91475a40cf9af2563df144b0f64
This is an initial attempt at making a simple C pin API for writing
things like I2C drivers in C.
