N76E003_IR_Receiver_NEC

Receive ir data from ir remote with intterupt and timer capture.

To test this code, please using IR_TX_SOURCE at https://github.com/minhhieuec/Send_IR_Using_PWM_N76E003 or any ir remote which use NEC Protocol.

How to use

This code support receive ir data using pin intterupt or external interrupt on N76E003. To config number byte receive of data, please config:

#define IR_DATA_LEN 4 // 8 bytes

Pin interrupt

N76E003 support pin intterupt at any port. So you can choose any pin to use.

Note that: before call ir_rx_setup(IR_USE_PIN_IT); function, you need to config gpio pin for your ir receive led pin. Example:

P05_Input_Mode;
Enable_INT_Port0;
Enable_BIT5_FallEdge_Trig;
ir_rx_setup(IR_USE_PIN_IT);

At this time, this code only support intterupt on P05 pin. I will support for any pin in future.

External Interrupt (INT0, INT1)

When you use this mode, You don't need to config gpio for it. You only call ir_rx_setup(IR_USE_PIN_IT); function in setup.

At this time, this code only support INT1 intterrupt. I will support for INT0 later.
