Adafruit CircuitPython BusDevice TheI2CDeviceandSPIDevicehelper classes make managing transaction state on a bus easy. For example, they manage locking the bus to prevent other concurrent access. For SPI devices, it manages the chip select and protocol changes such as mode. For I2C, it manages ...

链中NeoPixels的数量是否有限制? NeoPixel链的最大长度没有固有限制,但最终您会遇到各种实践限制: RAM: NeoPixels需要主机微控制器提供一些RAM;更多像素=更多RAM。每个像素只有几个字节,但是由于大多数微控制器都受到相当有限的资源限制,因此对于大型项目来说,这是一个非常现实的考虑。 功耗:每个NeoPixel都会消耗一点...
CAN Bus is a small-scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet. CAN is 2 wire differenti...

In this section, we're going to do is learn how to scan the I2C bus for all connected devices. Then we're going to learn how to interact with an I2C device. We'll be using the Adafruit TSL2591, a common, low-cost light sensor. While the exact code we're running is specific to...
