嘿,嘿,
所以我用CapSense Express芯片很快一个原型+十段滑块的一个客户的项目。 它很有效,但是客户想要更长的滑动条。这已经是在最大长度不影响响应的线性度(这是音频电平,使线性度是重要的)但表达芯片不能做滑块双工。 我想如果我添加了第二个表达芯片,把两滑块一起,共享一个共同的传感器之间避免死区,这可能在很短的时间内做的伎俩,因为我还没有花时间去学习PSoC Creator在正常psoc4芯片创建相同的功能。 问题是,这是可能的吗?可以一段一个滑块连接两个CapSense Express芯片引脚?那会起作用吗?它会造成传感器读数的问题吗?疯狂的想法,但是我渴望实现这一尽快运行。 干杯 ~D 以上来自于百度翻译 以下为原文 Hey there all, So I used a Capsense Express chip to very quickly prototype a 2-button + 10-segment slider for a customer project. It worked, but the client wants a longer slider. It is already at the maximum length without compromising the linearity of the response (It's for audio level, so that linearity is important) - but the Express chips can't do slider diplexing. I thought if I added a second express chip and put two sliders together, sharing a common sensor in between to avoid a dead-zone, this might do the trick in a very short space of time, as I haven't had to take the time to learn PSOC creator to create the same functionality on a normal PSOC4 chip. Question is - is that possible? Can one segment of a slider be connected to two Capsense Express chip pins? Would that even work? Would it create a problem with the sensor reading? Crazy idea but I'm running on the desire to implement this as fast as possible. Cheers ~D |

你好,
滑块的期望在你的应用程序的长度是多少? 此外,正在使用哪种CasSoice Express设备? 如果你使用一个普通的传感器之间,可能有2的芯片之间的冲突,因为他们可能在不同时间段的普通扫描。 例如,一个芯片可以连接到地面,而其他芯片可以连接到地址复用器(扫描)。 因此,而不是使用的一种传感器,可以读取原始计数(差分计数)中的传感器(死区)和相邻的传感器使用的主机控制器和质心计算。 正如你所提到的,你也可以使用PSoC设备。 谢谢,Shanmathi 以上来自于百度翻译 以下为原文 Hi, What is the length of the slider expected in your application? Also, which CapSense express device is being used? If you use a common sensor in between, there may be a clash between the 2 chips, as they might scan the common segment at different time instants. For instance, one chip may connect it to ground, while the other chip may connect it to AMUX (to scan). So, instead of using a common sensor, you can read the raw counts (difference counts) of middle sensors (dead zone) and the adjacent sensors using host controller and calculate the centroid position. As you have mentioned, you could also use PSoC device. Thanks, Shanmathi |
