touchgfx包有问题

[zouzhe1]

@Aladdin-Wang
我是用RTT STDIO，按照你的教程bsp是1.1.0，都是用最新的包。使用的LED的模板
屏幕用的是原子800*480同配置的，触摸芯片也是9147.
显示可以显示图，但是不能动，不能数模，图里面没有曲线。

如附录文件所示；

终端显示出错的问题如下：
`[D/drv.sdram] sdram init success, mapped at 0xC0000000, size is 33554432 bytes, data width is 16
[I/I2C] I2C bus [i2c1] registered

找到问题了，在libraries - touchgfx_lib - TouchGFX - target - STM32TouchController.cpp
把x = 800 - read_data[0].x_coordinate; y = 480 - read_data[0].y_coordinate;
修改位
x = read_data[0].x_coordinate; y = read_data[0].y_coordinate;

即可正常用keil下载。

但是我又遇到了rtt stdio下载还是一样的问题没解决。
