37 * @brief C++ API for LPD8806
39 * This file defines the LPD8806 C++ interface for liblpd8806
46 * Instanciates a LPD8806 object
48 * @param pixelCount number of pixels in the strip
49 * @param csn chip slect pin
51 LPD8806 (uint16_t pixelCount, uint8_t csn);
54 * LPD8806 object destructor, basicaly it close SPI and the GPIO.
59 * @param pixelOffset pixel offset in the strip of pixel
64 void setPixelColor (uint16_t pixelOffset, uint8_t r, uint8_t g, uint8_t b);
67 * Write the data stored in array of pixels to the chip
72 * Return length of the led strip
74 uint16_t getStripLength (void);
77 * Return name of the component
85 mraa_spi_context m_spi;
86 mraa_gpio_context m_csnPinCtx;
89 uint8_t m_pixelsCount;
91 uint8_t readRegister (uint8_t reg);
92 void writeRegister (uint8_t reg, uint8_t data);
95 * Set chip select pin LOW
97 mraa_result_t CSOn ();
100 * Set chip select pin HIGH
102 mraa_result_t CSOff ();
