我使用TI的例程simpleBLEPeripheral，配置方面没有修改，仅仅在simpleProfileChangeCB中添加了IO口控制代码，例程中的IO口配置如下： P0SEL = 0; // Configure Port 0 as GPIO P1SEL = 0; // Configure Port 1 as GPIO P2SEL = 0; // Configure Port 2 as GPIO
P0DIR = 0xFC; // Port 0 pins P0.0 and P0.1 as input (buttons), // all others (P0.2-P0.7) as output P1DIR = 0xFF; // All port 1 pins (P1.0-P1.7) as output P2DIR = 0x1F; // All port 1 pins (P2.0-P2.4) as output
P0 = 0x03; // All pins on port 0 to low except for P0.0 and P0.1 (buttons) P1 = 0; // All pins on port 1 to low P2 = 0; // All pins on port 2 to low
