76 The H-Bridge Driver,One of the challenges of driving DC electric motors is that they sometimes need the capability to operate in reverse. To do this, the current flow must be reversed. Arranging for this requires additional hardware.呼吸 发表于 2025-3-25 09:50:20
Remote-Control Panel,Because of the Raspberry Pi’s small size and low cost, it is an attractive platform for remote-sensing applications. A remote station might need to sense control panel switches or push button events. This electronic problem sounds simple until you discover that switches and buttons suffer from ..清楚 发表于 2025-3-25 12:52:25
Pulse-Width Modulation,This chapter explores pulse-width modulation (PWM) using the Raspberry Pi. PWM is applied in motor control, light dimming, and servo controls, to name a few examples. To keep the hardware simple and the software small enough to read, we’re going to apply PWM to driving an analog meter in this chapter.FEIGN 发表于 2025-3-25 16:25:33

https://doi.org/10.1007/978-1-4842-4206-3anion MCP23S17 is available for SPI bus.) The I2C bus allows the chip to be remote from the Raspberry Pi, requiring only a four-wire ribbon cable (power, ground, and a pair of I2C bus lines). This chapter explores the features and limits of this peripheral.负担 发表于 2025-3-26 20:33:44
