ApIC32 MZ嵌入式图形与Stacked DRAM（DA）启动器套件LED存在问题

你没有表现出什么，你可以很容易地发现自己是什么问题。3，例如通过MPLABX上下文菜单/导航……然后你会知道哪些物理端口位的LED你（和谐？）代码假设。然后你应该看看你的D3310用户手册，你会发现：现在比较提到的D6…D8端口位与您的软件定义，这应该给你答案，其中错误坐。



以下为原文

You did not show what's behind
BSP_LEDOn(BSP_LED_1);
BSP_LEDOn(BSP_LED_2);
BSP_LEDOn(BSP_LED_3);

You can easily find out yourself what is the problem.
First look up the definitions of BSP_LED_1 .. 3, e.g. via MpLabX Context menu / Navigate ...
Then you will know which physical Port Bits for the LEDs your (Harmony?) code assumes.

Then you should look into your DM320010 user manual you will find:


Now compare the mentioned D6 ... D8 port bits with your software definitions and this should give you the answer, where the error sits.

你好，罗迪姆，谢谢你的回答！-）我用和声来创建一个FrRetos应用程序，我也点击了BSP支持。因此，访问DEVE板的代码要么是由协调生成的，要么是包含在其中的一些静态代码。无论是哪种方式，我都不是作者。我在用户手册和代码中看到了，从我所看到的，下面是正确的：ReD1是RH0DEL2上的RH2LeD3是RH1，而实际上是LED的代码：在代码中：对于LED 1位PoPOS＝0在代码中：对于LED 2位PoPs＝1在代码中：对于LED 3BITPOS＝2，这会给LeD2和LeD3带来错误的行为。重新分配BSPHE-LED常量解决了问题：但这意味着BSP码在错误上，据我所知。



以下为原文

Hello rodims, Thanks for the answer! :-)

I used Harmony to create a FreeRTOS app and i also clicked for BSP support. So the code that accesses the dev. board is either generated by Harmony or some static code that is included. Either way I am not the author.

I did look in the user manual, and the code, and from what I can see, the following is true:

LED1 is on RH0
LED2 is on RH2
LED3 is on RH1

And the code that actually turns on the LEDs:


PLIB_TEMPLATE void PORTS_PinSet_MCU32_PPS( PORTS_MODULE_ID index , PORTS_CHANNEL channel , PORTS_BIT_POS bitPos )
{
*(&LATBSET + (channel - 1) * 0x40) = 1< }


In the code: for LED 1 bitpos = 0
In the code: for LED 2 bitpos = 1
In the code: for LED 3 bitpos = 2

And this will give the wrong behaviour for LED2 and LED3. Redifining the BSP_LED constants solves the problem:

typedef enum
{
BSP_LED_3 = 1, //Used to be BSP_LED_3 = 0
BSP_LED_2 = 0, //Used to be BSP_LED_2 = 1
BSP_LED_1 = 2
} BSP_LED;


But that means that the bsp code is in error, as far as I can tell.
