Re: Chinese I2C Touchscreen panel HELP please! I'll owe you a beer

Ok, I've used python and xdotool to pickup the touch panel values, convert it, and submit it to xdotools for the input I'm looking for. So this will get the job done for now. Here's the python for anyone interested: import smbus import time import subprocess bus = smbus.SMBus(1) # For knowing your s...

Re: Chinese I2C Touchscreen panel HELP please! I'll owe you a beer

No link to the display as it's a custom designed display manufacturered in China. I'll see if I can get a photo of the IC for you tomorrow, but you'll likely not find any documentation on the IC. It's not well documented. Is there anything that can be done without already made drivers? I mean, I'm g...

Re: Chinese I2C Touchscreen panel HELP please! I'll owe you a beer

Or maybe there's an easy way to create a script or something that will mimic touch/mouse input based on the information I've already gathered? Any solution that gets the job done for now, I'm very ok with as this is just a proof of concept project I'm working on at the moment.

Chinese I2C Touchscreen panel HELP please! I'll owe you a beer

I have a cheap capacitive 4.3" screen from China that the touch panel is I2C. I have verified that the PI sees it via i2cdetect and it is outputting values as expected, which I have verified by running a script similar to one I've taken off of another post. Here is the script: import smbus, os from ...

Very similar experience here. I have a cheap resistive 4.3" screen from China that is I2C. I have verified that the PI sees it and it is outputting values as expected, which I have verified by running a script similar to one I've taken off of another post. Here is the script: import smbus, os from t...

Re: Any way to disable click and drag on touchscreen?

I'm interested in this as well. I am constantly having users accidentally drag when they are clicking. This causes unwanted highlighting and other problems.

Re: MAX31855 Thermocouple driver

Got the no connection thing under wraps. When I had everything on a breadboard I finally got all working nice and smooth. Once I soldered everything up I and run the scripts I get a few readings from each TC and then I randomly get these two errors thrown in that kill the scripts: Thermocouple short...

Re: MAX31855 Thermocouple driver

Sweet. I changed the CS_pins in the main file and the first time I ran it, it appeared that I got a correct first reading. Then I continued to get zeros every line after that. Also rerunning it I would continue to get zeros. Also now when I run the single max31855 file I get zeros now. EDIT: Now I'm...

Re: MAX31855 Thermocouple driver

Thanks for the info and the python! I have two Max31855 breakouts from adafruit and have one at a time working successfully. I'm kind of limited on gpios and was curious if you HAD to have ALL new pins for a 2nd MAX31855? I was hoping to get away with sharing pins with the 1st one, but so far my tri...

Re: Need for Industrial Quality RPi System

I am using several raspberry pis in industrial applications. I work for a company that creates heating and ac units. We were needing a pressure test system that would fill a production unit with X psi, hold it and then read the sensor to make sure it doesn't lose pressure. We had a quote from a comp...

Re: Furnace Fan - Run 10 minutes out of every hour

I have purchased a few of these and have been playing with them:

They work great for me. They also have 4 channel and 16 channel variations of this floating around.
