stm32
- 在STM32的I2C上摔了一跤,测试了官方提供的几个例程和库,都有不同缺陷,也无法弥补: 1、查询方式,在连续读数据的过程中不能中断 2、DMA方式类似,在同一DMA中I2C的级别必须最高,否则同1. 3、中断方式也不能有更高优先级中断I2C,否则同1. 鉴于以上原因,无奈的口线模拟了I2C。(仅仅代表个人看法,欢迎指正) 附件中的项目文件已经过测试,为感谢OUR这几年的帮助,先开源这个小程序-I2C on the STM32' s fall, the off

- 首先要说:是我自己写的你他地方下不到! 这是一个用PWM播放.wav歌曲文件的程序,歌曲本身已经被和代码一起固化到FLASH中了,想要听到美妙的歌曲你只需要把PB0经过一个滤波放大电路接到蜂鸣器或耳机插孔上,并把程序下到你的STM32中运行就可以了。 另外,看看这篇关于PWM播放.wav的文章:http://wmx0901.blog.163.com/blog/static/10320222020097171727367/edit/-First of all, to say: I
stm32_adc
- 此程序是基于STM32的AD应用程序,我们在这里设置ADC为连续转换模式,常规转换序列中有两路转换通道,分别是ADC_CH10(PC0)和ADC_CH16(片内温度传感器)。因为使用了自动多通道转换,数据的取出工作最适合使用DMA方式取出,so,我们在内存里开辟了一个u16 AD_Value[2]数组,并设置了相应的DMA模块,使ADC在每个通道转换结束后启动DMA传输,其缓冲区数据量为2个HalfWord,使两路通道的转换结果自动的分别落到AD_Value[0]和AD_Value[1]中。
