实验器材:
正点原子探索者STM32F407开发板
实验目的:
使用彩色TFTLCD显示屏制作简易示波器
硬件资源:
1,DS0(连接在PF9)
2,串口1(未使用 波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面)
3,ALIENTEK 4.3寸TFTLCD模块(通过FSMC驱动,FSMC_NE4接LCD片选/A6接RS)
4,ADC使用PA5引脚 采用TIMER3+DMA2_stream0+ADC1_PA5方式采集AD数据
5,波形绘制使用DMA中断 测量信息在主函数中完成
6,波形绘制部分可以选用画点或者划线 画点刷屏速度大概两倍于画线速度
实验现象:
本实验利用探索者STM32开发板连接ALIENTEK TFTLCD模块实现简易示波器功能
