I am trying to use a Waveshare e-Paper (2.9") with an Orange Pi Zero LTS. To enable the SPI interface, I have added this to /boot/armbianEnv.txt:
overlays=spi-add-cs1 spi-spidev
param_spidev_spi_bus=1
param_spidev_max_freq=10000000
and installed WiringPI from Github. The e-Paper module is connected to the following GPIO pins:
VCC: 3.3V
GND: GND
DIN: 19(phys)/11(wPi)
CLK: 23(phys)/14(wPi)
CS: 24(phys)/15(wPi)
DC: 22(phys)/13(wPi)
RST: 3(phys)/0(wPi)
BUSY: 5(phys)/1(wPi)
I have checked the connections by using the gpio command line tool to set all 6 ports above to low and to high,
