DS90UB983-Q1: Can the 983 support receiving interrupts from two different deserializers?

Part Number: DS90UB983-Q1
Other Parts Discussed in Thread: DS90UH984-Q1

We want to know how to use two interrupts at the same time to support the touch of two screens.

We are using a DS90UB983 as the add-serializer and DS90UB944 and DS90UB948 as the deserializers. Can 983 support this?

Please send the 983 configuration that supports two different deserializer interrupts?

    您好，

    已经收到了您的案例，调查需要些时间，感谢您的耐心等待。

    您好，

         您是否打算使用INTB或GPIO引脚来处理来自两个不同解串器的中断。

         您可以将每个相应端口的 REM_INTB 映射到不同的 GPIO。

    您好，

            目前我们的板子设计的983的INTB和gpio4来处理两个不同解串器的中断，目前也只有INTB的中断可以传过来，将gpio4配置为REM_INTB的始终传不过来，我们使用过你们datasheet里的配置也不行，是否对不同解串器需要有特殊配置？能否发一份参考的中断配置我们试一下；

            thanks！

    您好，

         您能否提供寄存器配置和系统的示意图，以便能了解哪个设备连接到哪个FPD-Link端口？

    您好，

          983的系统框图如下:

         

          int 硬件io 配置如下（红色选中的）：

          

    其中： port0上接的是TI944的屏， port1上接的是TI948的屏。
     
    软件目前的配置是：
    /*********************************************
                  **remote interrupt config
    *********************************************/
                  ti983_write_byte(ti_bridge->ti983_i2c, 0xc6, 0x21);
                  ti983_write_byte(ti_bridge->ti983_i2c, 0x1b, 0x88);        // to port0
                  ti983_write_byte(ti_bridge->ti983_i2c, 0x51, 0x83);
     
    这样配置后， port0上的屏中断可以透传过来， 使用示波器测量REM_INTB的引脚， 触屏可以看到示波器上有电平变化。 但是如果将参数配置为：
    /*********************************************
                  **remote interrupt config
    *********************************************/
                  ti983_write_byte(ti_bridge->ti983_i2c, 0xc6, 0x21);
                  ti983_write_byte(ti_bridge->ti983_i2c, 0x1b, 0x98);       // to port1
                  ti983_write_byte(ti_bridge->ti983_i2c, 0x51, 0x83);
    这里触摸port1对应的屏， 示波器上没有电平变化。 一直为高。 注：已确认屏端的INTB是有电平变化的。
    而且，示波器查看TI983的INTB对应的引脚， 它一直是高电平， 没有变化。
     
    另外， 也验证过网上查到的一些配置，如：
    983配置
    选择FPD Link1上的INTB中断输入配置
     
    ti983_write_byte(ti_bridge->ti983_i2c,,0xC6,0x21);
    ti983_write_byte(ti_bridge->ti983_i2c,0x1B,0x88);
    ti983_write_byte(ti_bridge->ti983_i2c,0x51,0x83);
    ti983_write_byte(ti_bridge->ti983_i2c,0x40,0x24);
    ti983_write_byte(ti_bridge->ti983_i2c,0x41,0x8C);
    ti983_write_byte(ti_bridge->ti983_i2c,0x42,0x20);
     
    选择FPD Link2上的INTB中断输入配置：
     
    ti983_write_byte(ti_bridge->ti983_i2c,0xC6,0x21);
    ti983_write_byte(ti_bridge->ti983_i2c,0x1B,0x98); 
    ti983_write_byte(ti_bridge->ti983_i2c,0x51,0x83);
    ti983_write_byte(ti_bridge->ti983_i2c,0x40,0x24);
    ti983_write_byte(ti_bridge->ti983_i2c,0x41,0x9C);
    ti983_write_byte(ti_bridge->ti983_i2c,0x42,0x20);
     
    这样配置后，结果也还是一样， port1上的屏中断传不过来。

    您好，

    没有在端口1上看到948的中断的原因是983主页面寄存器0xC6是端口特定的。983数据表中有一张表显示哪些寄存器适用某些端口。

    对您的脚本做了一些更改，以便在GPIO4上设置REM_INTB。

    您好，按照上一个note操作，示波器测量INTB一直是低电平，正常应该和GPIO4一样高电平，有中断后有被拉低的操作

    TI__Mastermind 35740 points

    您好，

          能否读取 983 MainPage 0x52 寄存器以查看 INTB 变低的原因？INTB 是全局中断信号，因此可能有另一个中断将其拉低。

  • 0 回复 Alice
    Prodigy 100 points

    您好，上电不进行上述操作，该中断脚为高电平，而且0x52的值为0x00，做完上述操作0x52的值为0x82是否正常，而且发现在输完i2cset -y -f 1 0x0c 0xc6 0x21 b后就会被拉低为低电平

    TI__Mastermind 35740 points

    您好，

           当寄存器0x51 = 0x82时，这是预期的行为。这意味着FPD TX 1上的中断将传播到全局中断引脚(INTB)。

          为了防止这种行为，您可以将983寄存器0x51写为0x81。

         您仍将在寄存器0x52中看到REM_INTB已切换的指示，但由于被屏蔽，它不会影响INTB。请参见我测试的脚本和截图。

          

          

                  ti983_write_byte(ti_bridge->ti983_i2c, 0x2d, 0x02); //Enable writes to TX port 1 only
              ti983_write_byte(ti_bridge->ti983_i2c, 0xc6, 0x21);
              ti983_write_byte(ti_bridge->ti983_i2c, 0x2d, 0x01); //Change back to default
              ti983_write_byte(ti_bridge->ti983_i2c, 0x1b, 0x98);       // to port1
              ti983_write_byte(ti_bridge->ti983_i2c, 0x3F, 0xEF); //GPIO input disable
              ti983_write_byte(ti_bridge->ti983_i2c, 0x51, 0x81); //Enable interrupts for FPD TX 0 only

    您好，

    目前我们的板子设计的983的INTB和gpio4来处理两个不同解串器的中断，目前也只有INTB的中断可以传过来，将gpio4配置为REM_INTB的始终传不过来，我们使用过你们datasheet里的配置也不行，是否对不同解串器需要有特殊配置？能否发一份参考的中断配置我们试一下；

    抱歉，之前同步的信息有误，另外更正一下，目前也只有gpio4/REM_INTB的中断可以传过来，配置为INTB的始终传不过来

    Hi Alice

    配置看最新回复，INTB对应port0，REM_INTB对应prot1该如何配置

  • 0 回复 yingdong ou
    TI__Mastermind 35740 points

    您好，      

          根据之前的说明，示波器将INTB测量为一个持续的低电平，而它通常应该像GPIO4一样处于高电平，在中断后被拉低。

          在中断后，INTB持续为低电平是预期的行为。

          我们在数据手册中指出，必须读取寄存器0xC7以允许INTB返回高电平。

          

          REM_INTB在GPIO4（983端口0 -> 944A），INTB来自943A端口1 -> 948

              ti983_write_byte(ti_bridge->ti983_i2c, 0x51, 0x83);

          如果您仍然有问题，请提供983主页面的寄存器设置。

    修改后intb会变成低电平，读取寄存器0xC7也依然是低电平，983主页面的寄存器设置如下，请参考，谢谢！

  • 0 回复 yingdong ou
    TI__Mastermind 35740 points

    您好，

         您还需要读取全局中断状态（983 主页面 0x52）。

        从您的寄存器转储中，我们可以看到 0x52 = 0x82。如果第七位被设置，则表明全局中断已被触发。

  • 0 回复 Alice
    Prodigy 10 points

    您好，十分抱歉我们这边因为其它事情耽搁导致回复晚了；

    根据上条note，我们这边尝试了触发中断后去读取寄存器0x52和0xc7，但intb依然为低电平，rem_intb/gpio4就一直为高电平，麻烦再帮忙看下是否有其它措施

  • 0 回复 Dennis Duncan
    TI__Mastermind 35740 points

    您好，

          在983主页面注册0x52时，它指出在中断触发后需要读取两个状态寄存器。

         请确认已经在读取FPD-Link III_PORT_STS1寄存器（983主页面0xC7）。

          还需要读取FPD-Link IV_PORT_STS1，该寄存器位于间接页面9寄存器0x9D。

    您好，Alice,按照您上面的回复，我们又读完0x52和0xc7后，再去读了page9的0x9d，读出来的值为0x60，但实际测量INTB脚还是低电平，没有恢复高电平

    您好，

          由于中断触发在SER的REM_INTB上显示，这可能是由于在设置FPD4连接之前没有正确设置FPD端口选择。

         您能否只分享脚本的GPIO编程部分？您是如何触发944A的中断的？

  • 0 回复 Alice

    Hi,Alice

    我看了下我们这边配置的code

    对gpio的配置仅有如下几行代码，其余的是您上边note里给的配置，没有其它地方有配置gpio了；
    ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x16, 0x90); //944 gpio 1
    ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x1f, 0x90); //944 gpio 10

    ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x44, 0x81); // set TP INT gpio config
    ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x13, 0xdf); // set TP INT gpio config

    我们是通过点击带有944a的触摸屏来触发中断的；

    thanks！

    您好，

    由于这个问题发生在端口1，您能否按顺序分享GPIO和中断设置脚本。
    可能与端口选择相关，并且要检查SER GPIO设置是否与FPD 3模式相匹配。
    您是否仍在运行下面的序列？
    /*********************************************

    您好，

          如上面所说，gpio的配置只有下面这两处，是给944配置的，完整的配置脚本上面也是有发过的，可以参考上面完整的配置脚本，其它地方就没配置过gpio了；

    ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x16, 0x90); //944 gpio 1
ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x1f, 0x90); //944 gpio 10

ti983_write_byte(ti_bridge->ti944_linka_i2c, 0x13, 0xdf); // set TP INT gpio config

    你之前发的配置我们是有加紧code里一直在运行的

    您好，

         每当deserializer生成的中断发生时，serializer上的中断不会消失，直到系统控制器处理deserializer上的中断源。

         对于 REM_INTB，这只会反映 944a DES 的中断状态。对 SER 或 DES 寄存器的读取不会清除它。
