[参考译文] BQ76952：数据存储器问题

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1036401/bq76952-data-memory-questions

器件型号：BQ76952
主题中讨论的其他器件： EV2400、 BQSTUDIO

HY TI 支持、

我有一些问题：

  1. 您能否为 BQ769x2提供 Excel 或 csv 格式的数据存储器摘要表(最好是  BQ76952)？  
    这将使我更快地进行代码开发、而不是从 pdf 文件复制和粘贴

  2. 未定义的存储器区域如何？ 例如  保护0x92B8和0x92B9未映射。(包含0x90、0x01)
    这些写入保护吗？

  3. 什么是"OTPXOR"部分？ 这是否意味着我可以写入 OTP 两次、OTP 段 XOR OTPXOR 段将加载到 DATAEMORY？

  4. 我想在生产线上将 EV2400器件用作简单(通用) USB 转 SPI 或 USB 转 I2C 接口、以进行校准和设置。
    是否有一个可以使用的公共.NET .dll 文件？

谢谢、

Attila

    您好 Attila、

    我们没有 Excel 格式。 但是，如果您下载最新版本的 BQ769x2微控制器示例代码(https://www.ti.com/lit/zip/sluc701 )，它会有一个头文件，该文件可能对数据存储器地址很有帮助。

    2.不要写入未定义的区域。 有一些专用寄存器、您可以修改一些重要的内容。

    3.我不知道你指的是什么。 您能告诉我您在哪里看到这种情况吗？

    4.我不确定这是否可行。 您可以向 当地的 TI 销售联系人申请 bqtoolsSDK 软件包的访问权限。 这可能会为您提供所需的内容。

    此致、

    Matt

    HY Matt、

    感谢您的回答

    1.不幸的是，它对我没有帮助。 对于我的定制代码、我需要与 pdf 数据存储器映射中相同的数据结构。
    属性位置地址、类型(U1、U2、I1、I2等)是什么、最小值、最大值、单位是什么
    2. TI 应记住用户关于 未定义区域的信息！ 用户 可能认为他们可以在一个块中编写段。 在本例中、我必须跳过仅为2个字节的"黑洞"
    请参阅随附的 bqStudio 导出文件(OTPXOR)

    此致、

    Attila

    您好 Attila、

    1.我为您生成了一个电子表格-请参阅下面的附件。

    e2e.ti.com/.../BQ769x2Header.xlsx

    2. 有一个不同的导出格式(.fs 文件)显示所有数据存储器设置的块写入。 如果要在数据存储器中写入所有寄存器、这可能是一个不错的选择。 许多用户只对他们想要修改的寄存器进行写入、因为这可能只是设置的较小百分比。

    3.啊，我明白你的意思。 OTP 存储器实际上有两个副本。 这允许您多次在 OTP 中对同一寄存器进行编程。 两个图像都以全零开始。 当器件在加电或复位后加载数据存储器时、它将使用 OTP 映射对默认值进行异或运算。 因此、从技术上讲、您可以对整个 OTP 进行2次写入、也可以在不同的时间写入不同的寄存器。请记住、您只能对每个寄存器进行2次编程。 有8个 OTP 校验和、因此对 OTP 的写入总共有8倍的限制。 最好将其视为一次性可编程、但如果需要、可以撤消某些操作。

    此致、

    Matt

    您好、Matt、

    感谢您提供 电子表格！ 非常有用。 但 它突出显示了头文件中的拼写错误。
    我假设 电子表格是从头文件部分生成的。 我按  地址排序了电子表格、突然注意到 了一个有趣的地方。  保护 OTC 延迟位于 0x929B 而非 0x920B。

    #define OTCThreshold 0x929A //Protections：OTC：Threshold
    #define OTCDelay 0x920B //保护：OTC：延迟
    #define OTCRecovery 0x929C //保护：OTC：恢复

    此致、

    Attila

    您好 Attila、

    非常感谢您的观看！ 我将在代码的下一修订版中更正此问题。
