## ARM-2D
|
||
|
||
|
||
### usage
|
||
|
||
|
||
|
||
在配置使用ARM-2D时，需要修改flash.ld文件
|
||
```
|
||
.text 0x882000:
|
||
{
|
||
```
|
||
解决资源跨区域问题：
|
||
```
|
||
.text :
|
||
{
|
||
```
|
||
|
||
同时需要修改 ***core_cm3.h*** 文件，注释掉头文件
|
||
|
||
```
|
||
#include "ec7xx.h"
|
||
```
|
||
|
||
|
||
针对不同的LCD修改长宽尺寸：
|
||
|
||
***arm_2d_disp_adapter_0.h***
|
||
```
|
||
# define __DISP0_CFG_SCEEN_WIDTH__ 240
|
||
# define __DISP0_CFG_SCEEN_HEIGHT__ 320
|
||
```
|
||
***arm_2d_cfg.h***
|
||
```
|
||
# define __GLCD_CFG_SCEEN_WIDTH__ 240
|
||
# define __GLCD_CFG_SCEEN_HEIGHT__ 320
|
||
```
|
||
针对不同的内存占用，设定 ***PFB block size***
|
||
|
||
```
|
||
# define __DISP0_CFG_PFB_BLOCK_WIDTH__ 240
|
||
# define __DISP0_CFG_PFB_BLOCK_HEIGHT__ 32
|
||
```
|
||
|
||
配置不同的demo,需要定义相关的编译宏
|
||
|
||
```
|
||
CFLAGS += -DRTE_Acceleration_Arm_2D_Extra_Controls
|
||
CFLAGS += -DRTE_Acceleration_Arm_2D_Helper_Disp_Adapter0
|
||
CFLAGS += -DRTE_Acceleration_Arm_2D_Extra_Benchmark
|
||
CFLAGS += -DRTE_Acceleration_Arm_2D_Extra_Benchmark_Watch_Panel
|
||
```
|
||
|
||
使用Benchmark_Generic需要定义如下宏
|
||
|
||
```
|
||
CFLAGS += -DRTE_Acceleration_Arm_2D_Extra_Benchmark
|
||
CFLAGS += -DRTE_Acceleration_Arm_2D_Extra_Benchmark_Generic
|
||
```
|
||
|
||
使用DMA+ISR方式使能相关宏定义
|
||
```
|
||
# define __DISP0_CFG_ENABLE_ASYNC_FLUSHING__ 1
|
||
```
|
||
针对横屏和竖屏的修改，不止要修改.h头文件，还需要对应修改LCD Fill相关参数 |
