tfmini(Plus)Console

Link TFmini(Plus) and PC using CP210x, CH341 etc USB to Serial (Maybe you need install their chip driver for OS):

myPort = new Serial(this, "COM12", 115200);
Change "COM12" to tfmini serial from device manager;

TFmini 9 bytes output:
[0x59, 0x59, distanceL, distanceH, strengthL, strengthH, Mode, 0x00, checksum]

We define a TFmini class:

classTFmini {
int distance, strength;
boolean complete;
TFmini(intdist, intstre, booleancomp) {
distance = dist;
strength = stre;
complete = comp;
}
voidupdate(Serialport) {
if(port.available() >8) {
//byte: [-128, 127]byte[] dataByte = port.readBytes();
int[] data =newint[9];
for(int i =0; i <9; i++) {
//data[i]: [0, 255]
data[i] = dataByte[i] >=0? dataByte[i] : (dataByte[i] +256); }
if(data[0] ==0x59&& data[1] ==0x59) {
int checksum =0;
for(int i =0; i <8; i++) {
checksum += data[i];
}
if(data[8] == checksum %256) {
distance = data[2] + data[3] *256;
strength = data[4] + data[5] *256;
complete =true;
}
}
}
}
}

update() can be used in serialEvent(). Output is (distance: cm, strength).
