esp8266: Add basic pyb.Pin class; supports output mode only. 2015-02-13 17:21:44 -05:00			`extern const mp_obj_type_t pyb_pin_type;`
esp8266: Add PWM support. 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. 2016-03-02 08:37:27 -05:00			`extern const mp_obj_type_t pyb_pwm_type;`
esp8266: Add pyb.ADC class 2015-05-18 12:35:56 -04:00			`extern const mp_obj_type_t pyb_adc_type;`
esp8266: Make pyb.RTC a type, and pyb.RTC() constructs an RTC object. This is the standard way of doing things, one should construct a peripheral object (even if it's a singleton). See issue #1330. 2015-06-22 18:03:17 -04:00			`extern const mp_obj_type_t pyb_rtc_type;`
esp8266: Add basic I2C driver, with init and writeto methods. Tested and working with SSD1306 I2C display. 2016-02-11 07:43:41 -05:00			`extern const mp_obj_type_t pyb_i2c_type;`
esp8266: Implement software SPI class. Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any pins. Only supports MSB output at the moment. 2016-03-01 17:53:23 -05:00			`extern const mp_obj_type_t pyb_spi_type;`
esp8266: Expose simple pin API at C level. 2015-12-28 19:19:23 -05:00
esp8266: Expose pin object as a public structure for use as C pin API. This is an initial attempt at making a simple C pin API for writing things like I2C drivers in C. 2016-02-11 06:41:58 -05:00			`typedef struct _pyb_pin_obj_t {`
