# MicroPython GNSS L76-L I2C driver
MicroPython library for accessin the [Quectel GNSS L76-L](http://www.quectel.com/product/l76l.htm) receiver over I2C. L76-L is a
concurrent receiver module integrating GPS, GLONASS, Galileo and QZSS systems.
## Usage
Using default I2C pins for ESP32.
```python
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.
```python
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.
```python
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)
```
