MicroPython GNSS L76-L I2C driver
MicroPython library for accessin the Quectel GNSS L76-L receiver over I2C. L76-L is a concurrent receiver module integrating GPS, GLONASS, Galileo and QZSS systems.
Usage
Using default I2C pins for ESP32.
import utime
from gnssl76l import GNSSL76L
receiver = GNSSL76L()
while True:
for sentence in receiver.sentences():
print(sentence)
print("\n")
utime.sleep_ms(1000)Custom I2C pins when using non ESP32 board.
import utime
from machine import I2C, Pin
from gnssl76l import GNSSL76L
i2c = I2C(scl=Pin(26), sda=Pin(25))
receiver = GNSSL76L(i2c)
while True:
for sentence in receiver.sentences():
print(sentence)
print("\n")
utime.sleep_ms(1000)More realistic usage with timer. If you get OSError: 26 or i2c driver install error after soft reboot do a hard reboot.
import micropython
from machine import I2C, Pin, Timer
from gnssl76l import GNSSL76L
micropython.alloc_emergency_exception_buf(100)
i2c = I2C(scl=Pin(26), sda=Pin(25))
receiver = GNSSL76L(i2c)
def read_receiver(timer):
for sentence in receiver.sentences():
print(sentence)
print("\n")
timer_0 = Timer(0)
timer_0.init(period=1000, mode=Timer.PERIODIC, callback=read_receiver)License
