TMS320F2812: TMS320F2812PGFA

Part Number: TMS320F2812
Other Parts Discussed in Thread: UNIFLASH, SM320F2812

你好,官方有TMS320F2812中CAN总线组网的相关资料与程序吗?我在官方例程中没找到相关的资料。另外TMS320F2812芯片如何程序烧写到片内?我没找到相关资料。

  • 您好,所有的例程都在SDK中给出了。资料基本都在芯片的详情页面给出了:https://www.ti.com.cn/product/cn/TMS320F2812

    在芯片的详情页面,硬件工具中前3个为支持该芯片的仿真器:

    还有TMDSEMU110-U

    也有一些第三方的仿真器。

    第4个C2000-GANG是量产用的烧录器:

    软件的话可以用CCS开发及调试;烧录软件UNIFLASHC2000-GANG有专门的软件。

  • 你好,现在我有下载器XDS200,通过UNIFLASHC2000-GANG这个软件我就可以烧录是吗?还有别的东西吗?

  • CCSTUDIO就可以下载调试;UNIFLASH是专门的烧录软件。

    C2000-GANG是量产用的烧录器,有专门的软件。

  • 你好,我用CCS编译的.out文件通过Uniflash软件下载,我发现下载是成功的但是断电后重启就没有程序了

    这个是我的下载界面,请帮我分析一下。

  • 不断电的话是可以运行的吧?

    我推测您没有将代码配置为下载到Flash中运行,看一下这篇FAQ:

    [FAQ] [常见问题解答] 闪存 - 如何将应用程序从 RAM 配置修改为flash配置?

  • 你好,请问有没有能耐高温200度3.3V转1.8V的电源芯片推荐的,我在网上好像都没找到这种芯片。

  • 你好,我买了一块SM320F2812HGS150这种耐高温芯片,它由一个外框把引脚引出来,由于是调试阶段我不太想把引脚剪掉,然后焊上去。我想问问有没有配套的卡座之类的可以做一个转接的。

  • 没有

  • 你好,我用SM320F2812这块芯片做了一块板子,原理图如下,

    在我测试仿真器连接的时候打印如下:

    [Start: Texas Instruments XDS100v1 USB Debug Probe_0]

    Execute the command:

    %ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

    This utility will attempt to reset the controller.
    This utility has successfully reset the controller.

    -----[Print the reset-command hardware log-file]-----------------------------

    The scan-path will be reset by toggling the JTAG TRST signal.
    The controller is the FTDI FT2232 with USB interface.
    The link from controller to target is direct (without cable).
    The software is configured for FTDI FT2232 features.
    The controller cannot monitor the value on the EMU[0] pin.
    The controller cannot monitor the value on the EMU[1] pin.
    The controller cannot control the timing on output pins.
    The controller cannot control the timing on input pins.
    The scan-path link-delay has been set to exactly '0' (0x0000).

    中间的这部分

    The controller cannot monitor the value on the EMU[0] pin.
    The controller cannot monitor the value on the EMU[1] pin.
    The controller cannot control the timing on output pins.
    The controller cannot control the timing on input pins.

    是不是有问题,我尝试在线仿真了一下,可以进入仿真的界面但是程序不动,我看这个信息,我测试了一下芯片的与板子的连接应该都是通的,尤其是下载口几个引脚的几个连接EMU[0]与EMU[1]这两个我也单独测过,发现连接没有问题,请帮我分析一下。

  • 你好,例程上设置的目标是C28xx,我把这个改成F2812,我通过逐步设置断点的方式,发现程序是可以跑的。但是功能用不出来,我试了下AD,SCI等例程都跑不出来功能,有些时候程序会跑飞了。这个是什么原因?这个代码是通用的吗?还是我哪个地方搞错了?

  • 您好,如果需要新的支持,请以合适的标题提出新问题,以便于我们识别及跟进,谢谢!

  • 好的

  • 非常感谢您的理解!
