Raspberry Pi C driver and Python Bindings for the TSL2561 sensor.
This driver is basically a port of the Adafruit TSL2561 Light Sensor Driver.
Install the following packages:
- i2c-tools
- libi2c-dev
- python-dev
sudo apt-get install i2c-tools libi2c-dev python-dev
In a next step we configure i2c on the Raspberry Pi.
Add the following lines to /boot/config.txt:
#i2c
dtparam=i2c_arm=on,i2c1=on
Edit the file /etc/modules and add the following line:
i2c-dev
Finally reboot:
sudo reboot
After the reboot you should be able to find the i2c device using the command below:
sudo i2cdetect -y 1
Just run make.
Run sudo python setup.py build
#include "tsl2561.h"
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
int main(int argc, char **argv) {
int address = 0x39;
char *i2c_device = "/dev/i2c-1";
void *tsl = tsl2561_init(address, i2c_device);
tsl2561_enable_autogain(tsl);
tsl2561_set_integration_time(tsl, TSL2561_INTEGRATION_TIME_13MS);
if(tsl == NULL){ // check if error is present
exit(1);
}
int c;
long lux;
for(c = 0; c < 5; c++){
lux = tsl2561_lux(tsl);
printf("lux %lu\n", lux);
usleep(3 * 1000 * 1000);
}
tsl2561_close(tsl);
i2c_device = NULL;
return 0;
