Bluetooth SPI client to OLED display?

Post by tato123 »

I'm a little new to hardware design however I am a software developer.

I am trying to build a client/server solution where the hardware device can receive bluetooth data and output through SPI to an adafruit 0.96" oled. I want to perform all the processing on a laptop and just push updates to the bluetooth microcontroller and have it refresh the OLED screen. The software development side I'm comfortable with however I'm not sure what kind of microcontroller I should select. One caveat is that I am trying to build a small form factor device, ideally something that can be worn on a wrist.

Any help or suggestions would be extremely helpful, thanks.

are you talking about the color OLED or the monochrome OLED?

OK, that rules out using a Trinket or Gemma - they don't have enough SRAM for that display. You could use a FLORA or an Arduino Micro or a Teensy. The Teensy would be the smallest of the three, but the FLORA will run on a 3.7V LiPo battery.

Whats the smallest option available for adding bluetooth support on one of those boards? Also would it be possible to drive led lights as well as the oled display from the boards listed at the same time?

That would be the EZ-Link:

Sure, you can drive LEDs as well as the display.
