初三去未来丈人家做客

恩，我的已经收到了

拍下了，谢谢楼主分享了。:victory:

效率好高啊， 买的人也很积极啊，眨眼间就有100多件被抢购了。:)

原帖由 rwogn 于 2011-11-9 10:17 发表 如何将Grace生成的初始化代码移植到IAR form MSP430中。 :tongue:

比较笨的办法是用CCS调试程序，并单步进入初始化函数即可复制代码，诡异的是怎么也找不到这些程序的目录，退出调试状态这些文件就关闭了

这么疏懒也有奖励实在是惭愧啊，以后要改变了。

为了方便看程序自己给demo程序画了流程图

其它穿孔 LDR 传感器的封装    能问一下这个是什么封装么？

good job:) thank you 劳驾这里改一下，这个看着不爽已经很久了  

IO的上拉电阻没设置

不同编译器出来的结果不一样？？？都出来三个不同结果了 1：  5*5*5           7*7*8          7*7 2:     5*5*5            6*7*8         6*7 3:      5*6*7           6*7*8         6*7 [ 本帖最后由 wl1336412 于 2011-10-27 20:16 编辑 ]

10.16新的一周即将开始，调整一下心情

群共享上有例程的硬件上集成了I2C，设置相应寄存器就成了，有啥不明白的？   14.2.4.1 I2C Master ModeTo configure the USI module as an I2C master the USIMST bit must be set. In master mode, clocks aregenerated by the USI module and output to the SCL line while USIIFG = 0. When USIIFG = 1, the SCLwill stop at the idle, or high, level. Multi-master operation is supported as described in the Arbitrationsection.The master supports slaves that are holding the SCL line low only when USIDIVx > 0. When USIDIVx isset to /1 clock division (USIDIVx = 0), connected slaves must not hold the SCL line low during datatransmission. Otherwise the communication may fail.14.2.4.2 I2C Slave ModeTo configure the USI module as an I2C slave the USIMST bit must be cleared. In slave mode, SCL is heldlow if USIIFG = 1, USISTTIFG = 1 or if USICNTx = 0. USISTTIFG must be cleared by software after theslave is setup and ready to receive the slave address from a master.14.2.4.3 I2C TransmitterIn transmitter mode, data is first loaded into USISRL. The output is enabled by setting USIOE and thetransmission is started by writing 8 into USICNTx. This clears USIIFG and SCL is generated in mastermode or released from being held low in slave mode. After the transmission of all 8 bits, USIIFG is set,and the clock signal on SCL is stopped in master mode or held low at the next low phase in slave mode.To receive the I2C acknowledgment bit, the USIOE bit is cleared with software and USICNTx is loadedwith 1. This clears USIIFG and one bit is received into USISRL. When USIIFG becomes set again, theLSB of USISRL is the received acknowledge bit and can be tested in software.

给楼主一个参考，看看他们怎么用的launchpad的 $('swf_CUJ').innerHTML=AC_FL_RunContent('width', '550', 'height', '400', 'allowNetworking', 'internal', 'allowScriptAccess', 'never', 'src', encodeURI('http://www.tudou.com/v/llE-9QkQEX0/&rpid=5679045/v.swf'), 'quality', 'high', 'bgcolor', '#ffffff', 'wmode', 'transparent', 'allowfullscreen', 'true'); [ 本帖最后由 wl1336412 于 2011-10-15 09:09 编辑 ]

受教了，多谢分享:)
