Usage

Below shows a sample usage of ADC78H89.

from iclib.adc78h89 import ADC78H89
from periphery import SPI

spi = SPI('/dev/spidev0.0', 3, 1e6)
adc78h89 = ADC78H89(spi)
voltages = adc78h89.sample_all()

print(voltages[ADC78H89.InputChannel.AIN1])
print(voltages[ADC78H89.InputChannel.GROUND])

Below shows a sample usage of MCP4161.

from iclib.mcp4161 import MCP4161
from periphery import SPI

spi = SPI('/dev/spidev0.0', 3, 1e6)
mcp4161 = MCP4161(spi)

mcp4161.set_wiper_step(123, True)  # eeprom
mcp4161.set_wiper_step(123)

Below shows a sample usage of SN74HCS137.

from time import sleep
from unittest.mock import MagicMock

from periphery import GPIO
from iclib.sn78hcs137 import SN74HCS137

latch_enable_gpio = GPIO('/dev/gpiochip0', 0, 'out', inverted=True)
strobe_input_gpio = GPIO('/dev/gpiochip0', 1, 'out', inverted=True)
address_select_0_gpio = GPIO('/dev/gpiochip0', 2, 'out', inverted=False)
address_select_1_gpio = GPIO('/dev/gpiochip0', 3, 'out', inverted=False)
address_select_2_gpio = GPIO('/dev/gpiochip0', 4, 'out', inverted=False)
sn78hcs137 = SN74HCS137(
    latch_enable_gpio,
    MagicMock(),
    strobe_input_gpio,
    address_select_0_gpio,
    address_select_1_gpio,
    address_select_2_gpio,
)

sn78hcs137.select(SN74HCS137.Address.Y3)
sleep(1)
sn78hcs137.deselect()

Below shows a sample usage of NHD-C12864A1Z-FSW-FBW-HTT.

from time import sleep

from periphery import GPIO, SPI
from iclib.nhd_c12864a1z_fsw_fbw_htt import NHDC12864A1ZFSWFBWHTT

spi = SPI('/dev/spidev0.0', 3, 10e6)
a0 = GPIO('/dev/gpiochip0', 8, 'out')
not_reset = GPIO('/dev/gpiochip0', 9, 'out')
display = NHDC12864A1ZFSWFBWHTT(spi, a0, not_reset)

display.clear_screen()

display.draw_rect(0, 0, 127, 63)

display.set_font('dejavusans.ttf')
display.set_size(8, 14)
display.draw_word('Welcome to Blue Sky solar racing! 12345678910', 2, 2)
display.set_size(16, 16)
display.draw_word('@#$%*^', 1, int(driver.HEIGHT * 0.7))
display.display()

sleep(5)

display.clear_screen()

 # Fill screen
 for row in range(display.HEIGHT)
     for col in range(display.WIDTH)
         display.write_pixel(col, row)

 display.display()

 # Create checkerboard pattern
 for row in range(display.HEIGHT)
     for col in range(display.WIDTH)
         if (row + col) % 2 == 1:  # Checker pattern
             display.clear_pixel(col, row)

Testing and Validation

ICLib has extensive test coverage, passes mypy static type checking with strict parameter, and has been validated through extensive use in real-life scenarios.
