#include "py/obj.h"
samd/machine_adc: Add the machine.ADC class. With the method read_u16(). Keyword arguments of the constructor are: - bits=n The resolution; default is 12. - average=n The average of samples, which are taken and cumulated. The default value is 16. Averaging by hw is faster than averaging in code. The ADC runs at a clock freq 1.5 MHz. A single 12 bit conversion takes 8 microseconds.
2022-06-05 04:34:23 -04:00
extern const mp_obj_type_t machine_adc_type;
samd/machine_dac: Add the machine.DAC class. It suuports 1 channel @ 10 bit for SAMD21, 2 channels @ 12 bit for SAMD51. Instantiation by: dac = machine.DAC(ch) # 0 or 1 Method write: dac.write(value) The output voltage range is 0..Vdd.
2022-06-07 14:37:44 -04:00
extern const mp_obj_type_t machine_dac_type;
samd: Rename machine I2C type consistently across ports. This renames: - machine_hw_i2c_type -> machine_i2c_type
2022-10-06 14:22:57 -04:00
extern const mp_obj_type_t machine_i2c_type;
samd: Add Pin and LED classes, and machine.unique_id.

samd/machine_pwm: Add the machine.PWM class. Features are: - 3 to 5 different frequency groups. - Freq range of 1Hz - 24 MHz. - Duty rate stays stable on freq change. Keyword options to the PWM constructor: - device=n Select a specific PWM device. If no device is specified, a free device is chosen, if available at that pin. - freq=nnnn - duty_u16=nnnn - duty_ns=nnnn - invert=True/False Allowing two outputs on the same device/channel to have complementary signals. If both freq and duty are provided, PWM output will start immediately. Pins at the same device have the same frequency. If the PWM output number exceeds the number of channels at the PWM device, the effctive channel_no is output_no % channel_count. So with a channel count of 4, output 7 is assigned to channel 3. Pins at a certain channel have the same frequency and duty rate, but may be seperately inverted.

extern const mp_obj_type_t machine_pwm_type;
samd/machine_spi: Add the machine.SPI class. Suported by both SAMD21 and SAMD51. It follows the generic API, except for the bits=nn option, which is not implemented (yet).
2022-06-05 11:02:46 -04:00
extern const mp_obj_type_t machine_spi_type;
samd/machine_timer: Add machine.Timer based on the shared soft-timer.
2022-06-06 05:13:25 -04:00
extern const mp_obj_type_t machine_timer_type;
samd/machine_uart: Add the machine.UART class. All board pins that have UART's assigned can be used. Baud rate range is 75 Baud to ~2 MBaud. No flow control yet, and only RX is buffered. TX buffer and flow control may be added later for SAMD51 with its larger RAM and Flash.
2022-06-05 09:03:52 -04:00
extern const mp_obj_type_t machine_uart_type;
samd/machine_wdt: Add the machine.WDT class.
2022-06-06 05:23:09 -04:00
extern const mp_obj_type_t machine_wdt_type;
samd: Add Pin and LED classes, and machine.unique_id.
