Thanks for your answer Dave! I think I understand it more, but I need more experimentation to make sure I fully understand it. It's not about sending the byte directly to the WS2812 but interpreting that byte and sending a corresponding byte that the slave would interpret as a 1-bit or a 0-bit. This...

Hi everyone, I'm currently writing my own WS2812 driver for training purposes. I dissected several github codes including Jan's driver and I can't understand the existence of the buf_bytes (0x88, 0x8E, 0xE8 and 0xEE) and why we use 1 byte for 2 bits of color. I assume it's the way SPI buses work, bu...

Hello everyone, I bought a continuous servo motor (FS90R) and wanted to make it turn in both directions using the speed function. With a positive argument, the motor goes CCW. Now, I calibrated it using the values from the datasheet, and if I try send the speed function with an argument < 0, it just...
