Pin Name
SPI Flash , display screen, and MCU can be connected using HSPI
interface
IO15(CS)
Currently the PWM interface has four channels, but users can extend
IO12(R),
the channels according to their own needs. PWM interface can be
IO15(G),
used to control LED lights, buzzers, relays, electronic machines, and
IO13(B)
so on.
The functionality of Infrared remote control interface can be
implemented via software programming. NEC coding, modulation,
IO5(IR_R) and demodulation are used by this interface. The frequency of
modulated carrier signal is 38KHz.
