I’ve added the Igaging SpeedMic and OriginCal to our list of Arduino connected Mitutoyo measurement equipment (Micrometer, Caliper, Dial Indicator, and DRO Scale). I made some improvements to our Mitutoyo Instructable to facilitate connection to the Igaging equipment. The Igaging SPC enabled gear is Mitutoyo compatible, using the same 52 bit data stream. It even uses a Mitutoyo SPC cable for connection (not the same cable as our Mitutoyo Coolant protected Micrometer).

Now comes with a new professionally made board!
Order interface Boards (one for each axis):
Options: |
int req = 5; //mic REQ line goes to pin 5 through q1 (arduino high pulls request line low)
int dat = 2; //mic Data line goes to pin 2
int clk = 3; //mic Clock line goes to pin 3
int i = 0; int j = 0; int k = 0;
byte mydata[14];
float num;
void setup() {
Serial.begin(9600);
pinMode(req, OUTPUT);
pinMode(clk, INPUT_PULLUP);
pinMode(dat, INPUT_PULLUP);
digitalWrite(req,LOW); // set request at LOW
}
void loop() { // get data from mic
digitalWrite(req, HIGH); // generate set request
for(i = 0; i < 13; i++ ) {
k = 0;
for (j = 0; j < 4; j++) {
while( digitalRead(clk) == LOW) {// hold until clock is high
}
while( digitalRead(clk) == HIGH) {// hold until clock is low
}
bitWrite(k, j, (digitalRead(dat) & 0x1)); // read data bits, and reverse order )
}
// extract data
mydata[i] = k;
}
// sign = mydata[4];
// decimal = mydata[11];
// units = mydata[12];
// assemble measurement from bytes
char buf[7];
for(int lp=0;lp<6;lp++){
buf[lp]=mydata[lp+5]+‘0’;
buf[6]=0;
num=atol(buf); //assembled measurement, no decimal place added
Serial.println(num/1000, 3); //add decimal
}
}

Hello
I’m having trouble purchasing the Mitutoyo interface board. Any idea what’s wrong?
Hey Alex, are you trying to buy it under options in this post?
it may be that something is wrong here:
buf [lp] = mydata [lp + 5] + ‘0’ ;
If you have a solution – thanks in advance.
greetings from Austria
hi im trying to extract data from the mitutoya dial indicator (id-c112x) , from the data connector i have soldered 5 wires , as per the manual pin 1 is gnd 2 is data, 3 is clk and pin 5 is req. after making the connectio when i run the above code, im not getting any result on the serial monitor . how should i interface dial and arduino. ??
Can I purchase the Mitutoyo Interface bare board, kit or fully assembled? fully assembled is preferred.

This board does not include a level shifter. Most Arduino boards are 5v or 3.3v but the signaling out of the SPC device is 1.5v (or less if the battery is not new). This puts the signaling right at the edge of what most microcontrollers can detect. (I use the Teensy platform and the controller seems to be less tolerant of lower voltages.) A level shifter would make this much more reliable, particularly with 5v controllers.
How / where can I you purchase the assembled Mitutoyo Interface board?
How do I purchase?
How do you purchase what?
You sell premade boards?
What’s included in the assembly package?
I’m from Mexico, how long would the friend package arrive?
Hi
It is a great project…well done and thanks for the effort.
I am a bit confused . I really would like to print score on lcd 16x 2 as you did, but I can’t see the code for this. Could you help me with this please.
Hey, I have a project back home and this is exactly what I need. What is the estimated delivery time for a assembled kit?
Gr, Emiel
in the line
"bitWrite(k, j, (digitalRead(dat) & 0x1)); // read data bits, and reverse order )"
what do the{ & 0x1} do?
It's a bit mask.
hi steve, why am i getting output 0.000 when i connect my dial gauge? I just soldered the cable to mitutoyo dial gauge and connect it to the circuit
Hello,
I tried the code and after some time of searching why it doesnt work i realized that it seems to be stuck in the " while ( digitalRead(CLK) == HIGH) {}" loop. Any ideas about how to fix this?
I done, Thank you so much!
do you have clk connected correctly?
soldered the cable to the dial gauge?
Hi, where did you buy the calipers?
https://amzn.to/2KqmhWC
I mean, the clock calipers.
But I mean the mutitoyo calipers
Are you referring to the dial indicators? https://amzn.to/2KqmhWC
did you mean the dial indicators? https://amzn.to/2KqmhWC
