Hello,
This is the print or reading from the software I produced from the book. It
works.
I tried a BBB with Grove Cape and it shut the board down and would not
power on. I tried it on the BBGW and it fried my TMP36 sensor. I touched
the sensor and it was blistering hot. I got burned, i.e. you mothers.
So, in hindsight, I will stick with the BBB and BBBW for now. I have an
older model that is only 2GB. It worked right from the get-go.
Here is the software and it works with GNDA_ADC and pin 'P9_40'.
var b = require('bonescript');
function readTemp() {
b.analogRead('P9_40', displayTemp);
}
function displayTemp(reading) {
var millivolts = reading.value * 1800;
var C = (millivolts - 500) / 10;
var F = (C * 9/5) + 32
console.log("C = " + C + "\tF = " + F);
}
setInterval(readTemp, 9000);
So...all is well that ends well.
Seth
