VisionFive.gpio 1.2.12

A module to control VisionFive GPIO ports

This package provides a Python module to control the GPIO on a VisionFive.

Support basic GPIO function including edge detection, I2C API, PWM API, SPI API。

Support python sample, such as: - GPIO basic operation including input and output - Sense HAT(B) basing I2C API - LED_Matrix to display logo about Starfive - uart_gps_demo to read gps information from GPS NEO-6M - pwm_led to test PWM module works well - edge_detection_basic about basic edge API usage - edge_with_waiting_time about edge detection with specific time - edge_with_LED_Matrix about trigger LED display by button - RPi_demo_#GPIO_basic#_run_on_VisionFive about running RPi GPIO demo on VisionFive board - RPi_demo_#PWM#_run_on_VisionFive about running RPi PWM demo on VisionFive board

how to use basic gpio API and I2C API

>>> import VisionFive.gpio as GPIO
>>> import VisionFive.i2c as I2C
>>>
>>> GPIO.setup(37, GPIO.OUT)
>>> GPIO.output(37, GPIO.HIGH)
>>> GPIO.setup(37, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
>>> GPIO.setup(37, GPIO.IN, pull_up_down=GPIO.PUD_UP)
>>> IVAL = GPIO.input(37)
>>>
>>> p = GPIO.PWM(37, 10)
>>> p.start(20)
>>> p.ChangeDutyRatio(50)
>>> p.ChangeFreq(20)
>>> p.stop()
>>>
>>>
>>> GPIO.setup(key_pin, GPIO.IN)
>>> GPIO.add_event_detect(37, GPIO.FALLING)
>>> GPIO.remove_event_detect(37)
>>>
>>> edge_detected = GPIO.wait_for_edge(key_pin, GPIO.FALLING, bouncetime=2, timeout=5000)
>>>
>>> #read and write data with i2c
>>> I2C_DEVICE = "/dev/i2c-1"
>>> SHTC3_I2C_ADDRESS = 0x70
>>>
>>> ret = I2C.open(I2C_DEVICE, SHTC3_I2C_ADDRESS)
>>>
>>> def SHTC3_WriteCommand(cmd):
>>>     buf0 =  (cmd >> 8)& 0xff
>>>     buf1 = cmd & 0xff
>>>     buf = [buf0, buf1]
>>>     I2C.write(buf)
>>>
>>> SHTC3_WriteCommand(0x401A)
>>> SHTC3_WriteCommand(0x7866)
>>> buf_list = I2C.read(3)
>>> I2C.close()
>>>
>>> #how to read and write data about ADXL345
>>> SPI.getdev('/dev/spidev1.0')
>>> SPI.setmode(500000, 3, 8)
>>>
>>> #set 0xaa to reg 0x1e
>>> SPI.write([0x1e,0xaa])
>>>
>>> #read value of reg 0x1e
>>> SPI.write([0x9e, 0x00])
>>> SPI.read(1)
>>> SPI.freedev()
