On this page I will document the process of creating a GUI for the HUG made by Xiomara. I ordered a bunch of hardware to get started, always a joy when new nerdy hardware arrives! 🙂
I ordered a Raspberry Pi with a LCD touchscreen (and some spare Arduino’s and ESP8266s ) to get started. After some software juggling I was happy to have the LCD up and running.
Next step is my first attempt in showing a fullscreen example based on an example from [educ8s]. This means I can now start on the actual interface front and back-end.
Before I start figuring out how to make kick-ass graphics appear on the screen I will start writing some code that allows me to interface with the available timers for the HUG and see how I can control them through some simple buttons and sliders. Which makes me think I need to figure out how to code a slider that outputs values between 0 and 254 for example. Let’s take a look…
Don’t you love google? I found that the python tkinter package has a neat little Scale widget that does exactly what I need!
Now let’s wait on those timers to see how to interface with them.
Meanwhile I have attached a USB serial to TTL adapter so I can transmit the values of the sliders to external devices. In this case I used a Arduino Pro Mini with a MicroView OLED attached to display the values.
I don’t know what format the timers expect the data to be in, but the current setup will be a good vantage point.
