CSB (CS): Slave chip select signal, active at low level. When it is at low level, the chip is enabled.
SCL (SCK/SCLK): Serial clock signal.
D/C (DC): Data/command control signal, write command (Command) when the level is low; write data (Data/parameter) when the level is high.
SDA (DIN): Serial data signal.
Timing: CPHL=0, CPOL=0, i.e. SPI mode 0.
Note: For specific information about SPI communication, you can search for information online on your own.
The e-paper used in this product uses "microcapsule electrophoresis display" technology for image display. The basic principle is that charged nanoparticles suspended in a liquid migrate under the action of an electric field. The e-paper display screen displays patterns by reflecting ambient light and does not require a backlight. Under ambient light, the e-paper display screen is clearly visible, with a viewing angle of almost 180°. Therefore, e-paper displays are ideal for reading.
For the computer, the way it stores data is that the high bits come first and the low bits come last, and each byte only has 8 bits, so there may be a slight change:
In this way, only 2 bytes are required to represent 16 pixels.
The 10.85inch e-Paper is a dual-IC controlled e-Paper screen, in addition to the above programming principle, please note the following
When connecting to the Raspberry Pi, you can directly plug the board into the 40PIN pin header of the Raspberry Pi, and be careful to align the pins.
If you choose to use an 10PIN cable to connect, please refer to the pin corresponding table below:
