I am able to turn on led's, now I want to take advantage of the adc read features.
I have a ds18b20 prob which I hook up to ground and pin 0 when i do an adc read on pin 0 i get a crazy ready which varies.

What types of temperature probes are compatible with the module? and do they require extra hardware. my the usermanual talks of these fancy feature but doesn't go into any detail.]]> 1 Sun, 04 Mar 2018 15:14:03 +0000 https://phpstack-776178-2640993.cloudwaysapps.com/threads/8-channel-usb-gpio-lcd.222/ https://phpstack-776178-2640993.cloudwaysapps.com/threads/8-channel-usb-gpio-lcd.222/ invalid@example.com (chaka) chaka According to your documentation: "This module has 8 on board 5V General purpose I/Os multiplexed with 6 Analog Inputs, each connected to individual screw terminals and associated drivers capable of controlling a large number of devices including DC motors(via PWM), Sensors, LEDs, LCD displays etc…"

I'm from Australia and hoping to interface between an Axia iQ Broadcast console to our playout software called Station Playlist. I have not worked with electronic circuitry before so I'm quite the newbie. I'd like to be able to press the softkey on the console to toggle the automate feature of the playout software. The playout software allows for serial communication but can also take keyboard hotkeys. How does one constantly poll for GPI with a momentary switch? At a loss to know what...

If it is, do you have some example codes?
Many external breakouts communicates using these protocols, so it would be very interesing to have this feature, like Adafruit's or Sparkfun's ones have.

Tee end goal is to get change notification from IO 0-7 and then after IDing which state changed, read the value present in the ADC for that IO.

I am having difficulty quite understanding what the output in the notify string indicated sin relation to which IOs are engaged.

For instance the following output was while I had GND => 04 and GND => 00

1) Send "gpio set 0". GPIO 0 goes high
2) Send "gpio read 0". Response is "1".
3) GPIO 0 goes low, as if you had sent "gpio clear 0".

Is this by design? If so, I can not read a GPIO port that is high without causing it to go low.]]> 4 Sat, 29 Oct 2016 22:14:47 +0000 https://phpstack-776178-2640993.cloudwaysapps.com/threads/bash-scripting-8-channel-usb-gpio.145/ https://phpstack-776178-2640993.cloudwaysapps.com/threads/bash-scripting-8-channel-usb-gpio.145/ invalid@example.com (Chalk-X CPG) Chalk-X CPG Thu, 27 Oct 2016 00:38:26 +0000 https://phpstack-776178-2640993.cloudwaysapps.com/threads/displaying-adc-data-on-a-gauge.142/ https://phpstack-776178-2640993.cloudwaysapps.com/threads/displaying-adc-data-on-a-gauge.142/ invalid@example.com (Brad) Brad
