  • SPI中的双缓冲SSPSR和SSPBUF有什么好处?

    Hi GuySi从数据表中引用这一点,这个双缓冲的接收数据(SSPBUF)允许下一个字节开始接收,从而接收刚刚接收到的数据,而这是U需要写的,因为它是同步的。所以双缓冲在这里是无用的。我错了吗? 以上来自于百度翻译 以下为原文 Hi guys i quote this from datasheet This double-buffering of the received data(SSPBUF) allows the next byte to start reception beforereading the data that was just received How this come while u need to write to read because it is synchronous? so the double buffering is useless here . am i wrong ?

  • HP 66311A DC Source上的低电流输出

    嗨伙计们,我买了一台二手HP 66311A DC Source。电压输出很完美,但电流限制在0.600安培左右。我试图重新校准当前值,任何程序的尝试都会以“超出范围”的方式返回。此外,15伏稳压器中的一个(现在不记得哪个)运行温度非常高 - 在一分钟的预热时间和没有负载后触摸太热。我有一种感觉,“分流钳”驱动电路是这里的罪魁祸首。我付不起修理费,有什么建议吗?这是通孔板。有人有单位的示意图吗?谢谢!拉里 以上来自于谷歌翻译 以下为原文Hi Folks, I bought a used HP 66311A DC Source. The voltage output is perfect however the current is limited to around 0.600 amps. I tried to recalibrate the current values, any attemps to program come back with "out of range". Also one of the 15 volt regulators (can't remember which right now) runs a very high temperature - too hot to touch after a minute of warm-up time and no load present. I have a feeling the "Shunt Clamp" drive circuit is the culprit here. I cannot afford to send it in for repair, any suggestions? It's the through-hole board. Anybody have a schematic diagram of the unit? Thanks! Larry

  • PIC18F46J50引脚RB1和RB2上的意外行为

    我的板应该使用引脚RB1和RB2,每个读取按钮按下。为此,我通过一个100K电阻将每个引脚连接到3V3电源线。这两个按钮然后“接地”在电阻器和PIC引脚之间的相应馈电。课本上的东西。我发现插脚总是按压读。一个多表检查显示,每个引脚上的电压大约是1V65,而不是我预期的3V3。在100K电阻之前,万用表读取一个稳定的3V3,所以很明显有东西在拉低电压。最后,作为最小功能测试,我只配置了数字、输出和高电平的引脚。为此,我绝对期望在引脚上看到3V3,但它仍然是1V65。如果情况可能不同的话,我使用PIC18LF46J50。还有一些额外的配置我忽略了吗?谢谢。 以上来自于百度翻译 以下为原文 My board is supposed to use pins RB1 and RB2 to each read a button press. For this I have each pin tied to the 3V3 power line via a 100K resistor. The two buttons then "ground" the corresponding feed between the resistor and the PIC pin. Textbook stuff. I found that the pins are always reading as pressed. A multi-meter check reveals that the voltage on each pin is around 1V65 rather than the 3V3 that I was expecting. The multi-meter reads a steady 3V3 BEFORE the 100K resistor, so clearly something is pulling the voltage down. Finally, as a minimum function test I merely configured the pins for digital, output and high. For this I would definitely expect to see 3V3 on the pins, but it is still 1V65. Just in case it might make a difference I am using the PIC18LF46J50 . Is there some additional configuration that I have overlooked? Thanks. ANCON1bits.PCFG8 = 1; /* Set RB2/AN8 for digital not analogue */ ANCON1bits.PCFG10 = 1; /* Set RB1/AN10 for digital not analogue */ INTCON2bits.RBPU = 1; /* Disable pull-up resistors just in case */ TRISBbits.TRISB2 = 0; /* Set pins for output */ TRISBbits.TRISB1 = 0; LATBbits.LATB2 = 1; /* Set pin output = high */ LATBbits.LATB1 = 1; /* Now I would expect to see 3V3 on the pins but something* is dragging down the voltage */
