Description Called before drawing an object on screen, it sets the color of lines and borders around shapes. stroke() expects 8-bit values for each of the red, green, and blue channels, but the screen does not display with this fidelity. The red and blue values are scaled to 5-bit color (32 discrete steps), and the […]

Description Erases everything currently on the LCD screen with the indicated color. Can be used in loop() to clear the screen. While background() expects 8-bit values for each of the red, green, and blue channels, the screen does not display with this fidelity. The red and blue values are scaled to 5-bit color (32 discrete […]

Description Transfers one byte over the SPI bus, both sending and receiving. Syntax SPI.transfer(val) Parameters val: the byte to send out over the bus. Returns the byte read from the bus.

Description Sets the SPI data mode: that is, clock polarity and phase. See the Wikipedia article on SPI for details. Syntax SPI.setDataMode(mode) Parameters mode: SPI_MODE0, SPI_MODE1, SPI_MODE2, or SPI_MODE3. mode Clock Polarity (CPOL) Clock Phase (CPHA) SPI_MODE0 0 0 SPI_MODE1 0 1 SPI_MODE2 1 0 SPI_MODE3 1 1 Returns None See also － setBitOrder() － […]

Description Sets the divider of the SPI clock. On 86Duino, the SPI clock is equal to 100/(2*divider) MHz. The dividers available are integer values from 1 to 4095. On 86Duino Coding 102 and before, the default divider setting is 800, which sets the SPI clock to 62.5KHz; and from Coding 103, the default setting is […]

Description Sets the order of the bits shifted out of and into the SPI bus, either LSBFIRST (least-significant bit first) or MSBFIRST (most-significant bit first). Syntax SPI.setBitOrder(order) Parameters order: either LSBFIRST or MSBFIRST Returns None See also － setClockDivider() － setDataMode() Libraries Reference Home The text of the 86Duino reference is a modification of the […]

This application note talks about system configuration to address problems associate with not able to locate the serial port and modem manager.(See the older version here before Coding 207) Step 1 Launch the terminal program. Step 2 In this section, we will talk about the steps to change Modem Manager’s settings, to prevent the Modem […]
