ADC的驱动中的feature
Up to 16 single-ended external analog inputs
用户要是同时接入16路,而且需要随时读取每路的值,在驱动力怎么实现啊??
• Single or continuous conversion (automatic return to idle after single conversion)
单次或者连续转换 是用户可以调函数来配置吗?
• Output Modes: (in right-justified unsigned format)
• 12-bit,
• 10-bit
• 8-bit
• Configurable sample time and conversion speed/power
这三个sample ,speed,power也都是用户天用函数可配置吗?
• Conversion complete and hardware average complete flag and interrupt
• Input clock selectable from up to four sources
• Asynchronous clock source for lower noise operation with option to output the clock
这一条是什么意思啊???异步时钟作为ADC的工作时钟来降噪?异步时钟是哪来的呀???外部接入的???还是ADC自己产生的??output the clock是什么意思啊???ADC会产生异步时钟输出???
• Selectable asynchronous hardware conversion trigger with hardware channel select
硬件触发了通道后,还要在软件里打开对应的通道吧???
• Selectable voltage reference, Internal, External, or Alternate
• Automatic compare with interrupt for less-than, greater-than or equal-to, within
range, or out-of-range, programmable value
这一条很迷惑,完全不知是什么功能??
• Operation in low power modes for lower noise operation
• Temperature sensor
• Hardware average function
• Self-calibration mode
建议你看一下函数手册,里面对函数调用有具体说明。
