Function Instruction
PWM
IO12(R),
IO15(G),IO13(B)
To control color, buzzer, relay, motor and so on.
IR
IO14(IR_T), IO5(IR_R)
IR Remote Control4 interface is implemented by software, the interface
use NEC coding and modem, 38KHz carrier modulation
ADC
TOUT
To detect VDD3P3 (Pin3,Pin4) power voltage an TOUT(Pin6) and input
voltage(can’t be use at the same time);
Sensor application.
I2C
IO14(SCL), IO2(SDA)
To connect to external sensor and display.
UART
UART0: TXD(U0TXD),
RXD(U0RXD),
IO15(RTS),
IO13(CTS)
To connect to external device UART interface.
Download U0TXD+U0RXD or GPIO2+U0RXD.
Communication (UART0): U0TXD, U0RXD, MTDO(U0RTS), MTCK(U0CTS)
Debug: UART1_TXD (GPIO2),it can be served as debug information print.
