I use wled on a NodeMCU in multiple projects and really like it! Thanks for your efforts!
However, now I’m working on a new project. It’s kind of a pixel LED matrix / wordclock with APA102. The current implementation is driven by a Microchip ATmega 8 bit microcontroller with self-written firmware.
However, to have better effects and to sync the matrix to my other wled devices, I wanted to add a wled NodeMCU to the setup.
Thus, instead of driving the apa102 directly from the ATMEL, I want to attach the apa to the wled and control wled from the ATMEL.
“control” would means: switch between presets, en- or disble specific leds.
Thus, I need an interface between the ATMEL and the wled.
TL;DR: is there a way to use some interface like UART, SPI, or the like to control wled instead of the well-known JSON-API or MQTT?
