User Projects / Code Examples / Tinyscreen+ AMG thermal camera

« on: February 25, 2019, 01:52:09 AM »

I made a tiny thermal camera with a Tinyscreen+ and an AMG Grideye sensor from Adafruit. Three of the buttons are used: to control the colormap, the interpolation mode, and emphasis. It has a pretty good framerate. It needs a 3d printed case, but I haven't got that far. Here is a picture and some code.

General Discussion / linux code upload and modemmanager

« on: September 28, 2018, 05:18:03 PM »

Another issue I had, just FYI:

I had alot of trouble uploading code to tinyscreen+ on Linux. Half the time it would fail or tell me the port was busy. This is due to ModemManager scoping out any serial ports to see if they are GSM modems. You can fix this by putting a udev rule something like this in /etc/udev/rules.d/77-arduino.rules

# stop modemmanager from checking every serial port for a modem.. it locks up the port
# for a few seconds and interferes with uploading.

# arduino
ATTRS{idVendor}=="2a03", ENV{ID_MM_DEVICE_IGNORE}="1"
# tinyscreen / atmel
ATTRS{idVendor}=="03eb", ENV{ID_MM_DEVICE_IGNORE}="1"

General Discussion / had to try 3 different usb cables

« on: September 15, 2018, 04:31:56 PM »

just FYI, I was about to ask for help becuase my tinyscreen+ wasn't showing up at all when I plugged it in. I had tried two different USB micro cables on 2 different computers. Then I tried a 3rd cable, and now it is working fine. Touchy cables or touchy connector, I wonder.
