Harmony的v2.02b图形堆栈的问题

首先是强制性的背景：MPLAB X IDE V3.55 xC32 V1.43Valm V2.02BPIC32 MX470F512L处理器NHD-4.3-48022EF-ASXNα-T LCDIS61WV51216BLL 10TLI外部存储器。我选择PIC32 MX470F512L的原因是我们对处理器有很好的经验，它具有外围引脚选择，以及如果需要的话，我可以回落到MLA。因为在Posial2.02B的应用程序文件夹中没有PIC32 MX项目，所以我的起点只是创建一个定制的BSP。这是相对简单的，在过去还不是一个问题，特别是因为我能够复制和修改现有的BSP的基础上类似的NeHavavin显示器使用电容触摸库。唯一不同的是，我选择的LCD使用4线电阻技术。开始，我会选择我的新BSP，然后是图形堆栈。与免费模板库文件一起工作，我能够根据PCAP电容显示正确地插入逻辑。根据我所知，正确的文件被配置和包含。当然，我会有错误，但是我希望得到一些帮助。具体来说，在两个文件中：DrviFxxLCcIGr.G.C和LiabaaLeNo.C.C.让我们从第一个文件开始，因为到现在为止我还没有得到第二个文件。编译器抱怨框架地址。生成的代码为DRVIVGFXLCCS.GANU.C对这个变量有定义，但它是注释出来的。同时，它只用于下面的代码：静态gfxl结果SaveDATA（空隙）{（dCH1csiz）！（＝1）；（DopCurt & Pt；PixelyDouthPrimeDMAYTX）；DMACONBITS.St=＝1；而（PMMODEBITS.STORY＝1）；和/或等待DMA传输被挂起/ /执行写γIFIFF BSPH-SRAMYA15STATESET BSPHSRAMYA15STATESET（（帧地址＞G＆G.0；15）＆0x1）；BSPH-SRAMYA17STATESET（（DRVLCCOBJ.IITDATA & GT；ActudioPoST）和0x1）；BSPH-SRAMYA18STATESET（（DRVLCCOBJ.IITDATA & GT；ActudioPoT & G＆T；1）和0x1）；/ /保存以前的地址值PREVADDRR＝PMADR；PMADRR＝帧地址；返回GFXY成功；}它从未设置，所以我不清楚这个SO如何ULD是固定的。需要修改DRVIGGFXLCCGNANICIOUTALAL.C.FTL文件，但如何修改？另一个问题是下面的行：PLIPHPMPReReWrdErthBoopLis tisClice（0, 1 -（（CNTXT & GT；DePlasyFiel-＆G.Atvest.VixLeftToSHIFT））；在定义FGFxDePlsFielf的定义中不存在IfxLooptToSHIFT。还有其他问题，但我们从这里开始。至少，知道开发人员意识到这些问题，并且它们将被固定在短时间内是很好的。



以下为原文

First the obligatory background:

MPLAB X IDE v3.55
XC32 v1.43
H ARMony v2.02b
PIC32MX470F512L processor
Newhaven NHD-4.3-480272EF-ASXN#-T LCD
IS61WV51216BLL-10TLI external memory

The reason I chose the PIC32MX470F512L is that we have had good experience with the processor, it has peripheral pin select, and I can fall back to MLA if need be.

Since there are no projects for PIC32MX in the apps folder for Harmony 2.02b, my starting point was simply to create a custom BSP. This is relatively straightforward and hasn't been an issue in the past, especially since I was able to copy and then modify an existing BSP based on a similar Newhaven display that uses the capacitive touch library. The only difference is that the lcd that I chose uses 4-wire resistive technology.

Starting out, I'll select my new BSP and then the Graphics stack. Having worked with free template library files, I was able to bolt in the correct logic based on the PCAP capacitive display. The correct files are configured and included as far as I can tell.

Naturally, I get errors, but there seems to be some quirks with the stack that I was hoping to get some help with. Specifically, in two files: drv_gfx_lcc_generic.c and libaria_harmony.c. Let's start with the first file, as I haven't gotten to the second file as of yet.

The compiler complains about _frameAddress. The generated code for drv_gfx_lcc_generic.c has a definition for this variable, but it is commented out. At the same time, it is only used in the following code:

static GFX_Result saveData(void)
{
while(DCH1CSIZ != 1);
while(DrawCount > PIXEL_DRAW_PER_DMA_TX);
DMACONbits.SUSPEND = 1;
while(PMMODEbits.BUSY == 1); //WAIT for DMA transfer to be suspended
//Perform Write
#ifdef BSP_SRAM_A15StateSet
BSP_SRAM_A15StateSet((_frameAddress >> 15)&0x1);
#endif
BSP_SRAM_A16StateSet((_frameAddress >> 16)&0x1);
BSP_SRAM_A17StateSet((drvLCCObj.initData->activePage)&0x1);
BSP_SRAM_A18StateSet((drvLCCObj.initData->activePage>>1)&0x1);

//Save previous address value
prevaddr = PMADDR;
PMADDR = _frameAddress;

return GFX_SUCCESS;
}

It is never set, so it's unclear to me how this should be fixed. The drv_gfx_lcc_generic_external.c.ftl file will need to be modified, but how?

Another issue is with the following line:

PLIB_PMP_ReadWriteStrobePolaritySelect(0, 1 - ((cntxt->display_info->attributes.inv_left_shift)));

inv_left_shift does not exist in the definition of GFX_DisplayInfo where it is defined.

There are other problems, but let's start with this. At a minimum, it would be nice to know that the developers are aware of these issues and that they will be fixed in short order.
