CY8C21534-24PVXI的P1 [1]的函数冲突

您可以使用P1（1）作为反馈电阻，同时也使用ISP。当您使用ISSP编程芯片时，反馈电阻器不会影响ISSP操作。请查看2014年关于ISSP的更多细节。只要ISSP引脚上的电阻器负载大于1K，就不会有问题。

          You can use P1[1] for the feedback resistor and at the same time use it for ISSP also. When you are programming the chip using the ISSP, the feedback resistor will not affect the ISSP operation. Check out AN2014 for more details about ISSP. As long as the resistor load on the ISSP pins is greater than 1K, there should be no problem.   

嗨，先生，我正在做一个关于4个按钮、1个滑块（8个扇区/段）和4个使用CY8C21534-24PVXI的LED的项目。我的按钮工作得很好（我可以点亮每个按钮上的LED），但是滑块工作不正常（只有5个扇区工作，休息不工作）。在这个项目中，我还尝试使用TX8SW用户模块使用多图。我不能使用P1 [ 5 ]的数据输出（I2C SDA）的目的，因为它是由反馈电阻器（10K）使用。然后，我尝试在P1〔1〕中连接10K电阻（由ISSP使用），并为I2C SDA配置P1〔5〕，但LED闪烁而无手指存在。我使用的是CyPress例子的C代码，下面附上。请帮助我解决这个问题。谢谢你乔尔

  Hi Sir,
I'm doing a project on Capsense with 4 buttons, 1 slider(8 sectors/segments) and 4 LEDs using CY8C21534-24PVXI. My buttons were working fine (I could lit the LEDs for each tapping on the buttons), but the sliders were not working properly (only 5 sectors were working; rest were not working).

I'm also trying to use Multichart in this project using TX8SW user-module. I couldn't use P1[5] for the Data out (I2C SDA) purpose as it is used by feedback resistor (10K). Then, I tried connecting 10K resistor in P1[1] (used by ISSP), and configuring P1[5] for I2C SDA, but the LEDs were flashing without finger presence.

I'm using C code from Cypress examples and it is attached below.

Please help me out from this issues.

Thanking you
Joel

对不起，在我以前的邮件中有一个错误，我使用的是2K（10K）的反馈电阻和10nF的CMOD。

  Sorry, there's a mistake in my previous mail, I'm using feedback resistor of 2K(not 10K) and Cmod of 10nF.
