smartsolar 0 Posted June 6, 2023 Does rockchip processor fail to run ws281x LED or does no one try to build library for it . All the available library for ws281x are same for tinkerboard. All of them keep showing HW revision version not support. Some of my point during research are: 1)Broadcom processor have Videocon base address but rockchip processor doesnot include or no need of it. To change hardware information inside rpi_ws2811 library it need of this address so ioctl error occur. 2)Some of our friend told me to use of diozero library for tinkerboard, and diozero official also clam that it work on rockchip 3288 processor. Problem is I can't use of SPI mode due to robustness of my hardware configuration. And diozero official claming for the use of SPI mode instead of as of rpi_ws2811. Any one can help me for this one without changing circuit diagram. I have 5mm round ws2811 single led where i attach VCC to 3.3v GND to ground and Din pin to 32 pin number (i.e PWM pin 3). It is what i have done inside raspberry pi so i need to do same for tinkerbaord. Any tinkerboard expert are here to guide me for this? Share this post Link to post Share on other sites
gang 1 Posted June 6, 2023 I got same qustion, If you has some method, share with me please. 1 Share this post Link to post Share on other sites
