Description: 飞思卡尔MPC5554 target
To build your project, use the menu Project > Make or press F7.
This will build the selected target.-This is release 1.00 of the eTPU function set1. The package contains the
binary image of the eTPU code for the CPU to use, the source code and the
interface files for the function APIs.
This release contains the GPIO, PWM, UART, QOM, SM and SPI functions which have
passed testing (the PWM function has had DMA requests added but has not been
re-tested yet). In addition to support development work with the eTPU the IC and
PPA functions are also included. These functions are being tested and
should be considered prototypes only be used for testing.

Description: lm3s811 程序
对LED和KEY的编程，采用封装好“驱动库”模式，只要在工程里添加LED和KEY的驱动程序，就能运用自如。
例如对LED的操作就很简单：
LED_Init(LED1) // 只初始化LED1，而对LED2和LED3所在的GPIO管脚无影响
LED_Init(LED1 | LED2 | LED3) // 同时初始化3只LED
LED_On(LED2 | LED3) // 同时点亮LED2和LED3，而LED1的状态保持不变
此外还有LED_Off()和LED_Toggle()两个操作函数，用法都是类似的。-KEY programming on the LED and using the package good " driver library" model, just add the LED and the KEY Project in the driver, you can use with ease. For example, the operation of the LED is simple: LED_Init (LED1) // only initialize the LED1, LED2 and LED3 against GPIO pins where no effect LED_Init (LED1 | LED2 | LED3) // also initialize 3 only LED LED_On (LED2 | LED3) // while light LED2 and LED3, LED1 state remains unchanged while the addition LED_Off () and LED_Toggle () function of the two operations, usage is similar.

Description: SCCB协议和I2C协议的区别 SCCB是简化的I2C协议，SIO-l是串行时钟输入线，SIO-O是串行双向数据线，分别相当于I2C协议的SCL和SDA。SCCB的...
-SCCB protocol and I2C protocol differences
SCCB is to simplify the I2C protocol, SIO-l is the serial clock input line, SIO-O is a bidirectional serial data line, respectively, equivalent to the I2C protocol SCL and SDA. SCCB and I2C bus timing is basically the same, the response signal ACK is called a transmission unit of the first nine, divided into Don t care and NA. Don t care bits generated by the slave NA bits generated by the master, the SCCB does not support multi-byte read and write, NA bit must be high. In addition, SCCB did not repeat the initial concept, so the SCCB read cycle, when the host sending the on-chip register address, you must send a bus stop conditions. Otherwise, send the read command, the slave will not respond to signals generated Don t care.
SCCB as I2C and some nuances, so the use of GPIO analog SCCB bus way. SCL pin is always connected to the output mode is set, and the SDA pin is connected to the data transfer process, by setting the value of IODIR
