Mindstorms EV3 and the VL53l01x laser distance sensor

The VL53L0x is a very nice and small 2 meter measuring laser distance sensor.

So why not use it as replaced for the LEGO EV3 Ultrasonic sensor.

Take a Pro-min 5V 328P or 328PB controller connect the Pololu VL53L0x breakout board and make it an EV3 Uart sensor that measures cm or inch.

The 2 resistors 2k2 and 220 ohm are optional .

Than I made a EV3-G block for it with cm and inch compare and measure .

That's all folks.

Warning:

The Arduino code I made is for a 328PB board, if you want to use a 328P you

need the softwareserial driver and the Uartemulationsoft library from:

https://github.com/lawrie/EV3_Dexter_Industries_Sensors/tree/master/EV3_arduino

There is a bug in the Uart emulation library's, DATA32 and DATAF will not work.

I updated the hardware library. that is with the my Arduino code zip file.

If you want to use the soft version of the uart library change the code:

Code was:
void EV3UARTEmulation::send_data32(long l) {
byte bb[4];
bb[0] = l & 0xFF;
bb[1] = (l >> 8) & 0xFF;
bb[2] = (l >> 16) & 0xFF;
bb[3] = (l >> 24) & 0xFF;
send_cmd(CMD_DATA | (2 << CMD_LLL_SHIFT) | current_mode, bb, 4);
}

=====================================================

I changed it into:
void EV3UARTEmulation::send_data32(long l) {
byte bb[4];
bb[0] = l & 0xFF;
bb[1] = (l >> 8) & 0xFF;
bb[2] = (l >> 16) & 0xFF;
bb[3] = (l >> 24) & 0xFF;
send_cmd(CMD_DATA | (2 << CMD_LLL_SHIFT) | current_mode, bb, 4);
}

Do not connect the power supply's of the USB TTL to serial and the EV3 at the same time. This will destroy one of both.

Optional:

You can also use the VL53L1x laser sensor, this one measures up to 4 meters.

But you have to change the Arduino code not the EV3 block

Or connect more than one VL53Lxx sensor. Maybe a project for the next time.
