pcDuino with RF24L01 问题求教
我想用pcDuino 与 RF24GL01 的模块通讯。发现一个问题，编译的时候出现SPI的库不兼容的情况。标准的SPI 库：
class SPIClass {
public:
inline static byte transfer(byte _data);
// SPI Configuration methods
inline static void attachInterrupt();
inline static void detachInterrupt(); // Default
static void begin(); // Default
static void end();
static void setBitOrder(uint8_t);
static void setDataMode(uint8_t);
static void setClockDivider(uint8_t);
};
pcDuino 上的SPI 库
class SPIClass {
public:
SPIClass();
~SPIClass();
void begin();
void end();
void setBitOrder(int);
void setDataMode(int);
void setClockDivider(int);
char transfer(char val, int transferMode);
private:
int _fd;
int _speed;
};
Mirf的库调用的transfer(byte _data); 是一个参数，而pcDuino上的是 char transfer(char val, int transferMode); 两个参数。
并且其它的函数也不相同。
编译的时候出现：

求高手指点一下，多谢。

做这两个修改后，编译通过。但不知道能不能用。
搞定了，截图为证。

很强大 今天又看了一下，和用Arduino的做了对比，完全一样。
