Was going to use something like https://github.com/adafruit/Adafruit_CircuitPython_Dash_Display for sensor readouts attached via I2C that were then going to be pushed up via aio, but the responsiveness of the UI framework is, um, interesting

got a SGP30/ PIR/VCNL4020/BME680 (that i still need to short cause of I2C address overlap)

#

depending on your display device, I2c may not be the best choice for a screen that needs to refresh with lots of pixel changes every few milliseconds

#

I find an SPI screen was much better able to keep up with my project that told me about the state of an LED strip very quickly

it's the display that's wired into the funhouse. not sure what the interface is

#

right, on a funhouse

#

one sec, will look

#

https://learn.adafruit.com/adafruit-funhouse/pinouts interesting, it doesn't explicitly say

#

I could be mistaken but pretty sure MOSI, SCK -> that's SPI

#

way more data pins than than 2 at least (SCL/SDA)

#

anyways, are you familiar with any 3rd party graphical libs that are good for GUIs, more performant than displayio/dash_display?

thick oasis Feb 11, 2024, 4:18 AM

#

I've used some super basic ones to draw shapes and make buttons before

#

tbh display io worked great for me

#

The issue is latency?

#

I ran into this with a NeoTrellis a long time back trying to drive a oled display over i2c to it's edge, until I pitched bended the DAC 😄

#

issue is latency/consistency. it'll either be responsive to 100ms delayed on reaction either direction, in some cases not registering the button press at all

#

would you mind sharing your code?

#

I have a funhouse I can plug in and test with
