代码收藏家 TI-MSPM0G3507与SPI串口连接3.5寸屏幕详解
写在前面
备战2024电赛，使用到了TI开发板,型号MSPM0G3507，该开发板除文档外，网上资料稀少。
由于TI-MSPM0G3507，SPI串口连接TFT180屏幕该篇博客所选屏幕不符合本届电赛清单要求，现在为大家提供spi连接3.5寸屏幕(ILI9488芯片)的代码，以促共同进步。

配置
由于此代码由之前有关TFT180的博客修改而来，而有些定义在我的仓库中已经提取到COMMON.h，所以下列定义要在TFT180的博客中拿到或者直接在我的开源仓库中下载源码
color_enum
const uint8_t ascii_font_8x16[][16];
int abs(int x);
void func_float_to_str(char *str, float number, uint8_t point_bit);
syscfg配置与TFT180一样
一个SPI，命名为TFT_SPI
四个GPIO，端口命名为TFT
四个PIN命名为DC,RES,CS,BL
四个PIN都是Output，其中前两个默认低电平，后两个默认高电平
后话
