CryptoTicker is an information display board that supports over 1500 coin pairs. The PCB consists of 4 individual 1.3″ OLED displays controlled by an ESP32. These displays can show a coin pair each. The display outputs are shifted using a multiplexor. Updating or changing the information on the fly is possible from the localhost web server that is running on the device. Vertical and Horizontal positioning is possible. There are 4 programmable push-buttons located on the back of the device.
The device can be extendable to support up to 8 displays or with extra multiplexors up to 64 displays.
The software is written in MicroPython https://micropython.org. MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments.
