SGPIO inverted clock qualifier Hi, With bits 6:5 of SGPIO_MUX_CFG the QUALIFIER_MODE is selected (0x0=enable, 0x1=disable, 0x2=slice, 0x3=pin).With bit 8 (INV_QUALIFIER) of SLICE_MUX_CFG one can invert the qualifier (0x0=normal qualifier, 0x1=inverte…
LPC4350 SGPIO Experimentation The NXP LPC43xx microcontrollers have an interesting, programmable serial peripheral called the SGPIO (Serial GPIO). It consists of a slew of counters and shift registers that can be configured to serialize and deseriali…
LPC43xx SGPIO Configuration The LPC43xx SGPIO peripheral is used to move samples between USB and the ADC/DAC chip (MAX5864). The SGPIO is a peripheral that has a bunch of 32-bit shift registers. These shift registers can be configured to act as a par…
The SGPIO output pins SGPIO14 and SGPIO15 can trigger a GPDMA request SGPIO pins SGPIO14 and SGPIO15 can trigger a GPDMA request. < Output = '1' > To generate the request, program a pulse in the bit stream of slice 14 or 15. For example, use a patte…
在 PE文件头的 IMAGE_OPTIONAL_HEADER 结构中的 DataDirectory(数据目录表) 的第二个成员就是指向输入表的.每个被链接进来的 DLL文件都分别对应一个 IMAGE_IMPORT_DESCRIPTOR (简称IID) 数组结构. typedef struct _IMAGE_IMPORT_DESCRIPTOR { union { DWORD Characteristics; // 0 for terminating null import descriptor D…
数据库中的数据在不同的数据库中转换来装换去,由于不同库可能使用了不同的字符集,所以可能导致结果数据乱码问题.此次是在一个作业中跑数据,跑完数据前台数据显示出现乱码,检查了作业中的多有中间过程表,包括表输入的预览,表中的数据都是正常的,可想而知,问题肯定是处在“表输入”到“表输出”这个中间的转换环节上,根据能想到的,应该是字符集问题,为了更有保障的“表输入”和“表输出”的字符集相同,所以在表输入输出中.都添加了字符集的配置参数characterEncoding,值为utf8, utf8  和  U…
I²C SGPIO Configuration SGPIO is a hardware feature of LPC4300 series. There are 16 SGPIO pins called from SGPIO 0 to SGPIO 15. SGPIO is one of the functions of LPC 4300 pins which can be chosen. SGPIO could work as standard GPIO pins, or do stream p…
要获取用户输入的待办事项,发送给服务器,这样才能使用某种方式保存待办事项,然后在显示给用户查看. 上次运行测试指出无法保存用户的输入.现在,要使用HTML post请求. 若想让浏览器发送POST请求,要给<input>元素指定name=属性,然后把他放在<form>标签中,并为<form>标签指定method=POST属性,这样浏览器才能向服务器发送POST请求. 调整一下lists/templates/home.html中的模板 <html> <h…
模式匹配 所有位串均具有模式匹配功能. 该功能可用于检测启动代码等.要使用该功能,则必须用需匹配的模式来对REG_SS 编程 (请注意, POS 达到零时 REG_SS 不会与 REG  交换!) MATCH_MODE 位必须设为1. 输入数据 REG 现在与已编程的模式 REG_SS 相比较.发现匹配时会提出模式匹配中断. Bit MATCH_MODE selects whether the match filter is active or whether data is captured.…
