Change I2C Address for Multiple Sensors
Using the new I2C address change feature, you can also change the address for
multiple sensors using the PWR_EN line connected to Arduino's digital pins.
Address changes will be lost on power off.
Process
------------------------------------------------------------------------------
1.
Parameters
------------------------------------------------------------------------------
- numberOfSensors: int representing the number of sensors you have connected
- pinArray: array of the digital pins your sensors' PWR_EN line is connected
to
- i2cAddressArray: array of the I2C address you want to assign to your sen-
sors, the order should reflect the order of the pinArray (see not for poss-
ible addresses below)
- usePartyLine(optional): true/false value of weather or not to leave 0x62
available to all sensors for write (default is false)
Example Usage
------------------------------------------------------------------------------
1. // Assign new address to the sensors connected to sensorsPins and disable
// 0x62 as a partyline to talk to all of the sensors
int sensorPins[] = {2,3,4};
unsigned char addresses[] = {0x66,0x68,0x64};
myLidarLiteInstance.changeAddressMultisensor(3,sensorPins,addresses);
Notes
------------------------------------------------------------------------------
Possible Address for LIDAR-Lite
7-bit address in binary form need to end in "0". Example: 0x62 = 01100010 so
that works well for us. Essentially any even numbered hex value will work
for 7-bit address.
8-bit read address in binary form need to end in "00". Example: the default
8-bit read address for LIDAR-Lite is 0xc4 = 011000100. Essentially any hex
value evenly divisable by "4" will work.
