目前芯片定义TOUT(Pin6)位ADC端口,如下: ADC端口(Pin6 TOUT)可提供一下两种应用,单一下两种应用不可同时使用: ① 测量VDD3P3管脚3和4上的电源电压: 测量PA_VDD管脚电压的函数是:uint16 system_get_vdd33(void) ② 测量TOUT管脚6的输入电压: 测量TOUT管脚电压的函数是:uint16 system_adc_read(void) 3.2 应...

10-bit ADC (successive approximation ADC) † Both the CPU and flash clock speeds can be doubled by overclocking on some devices. CPU can be run at 160 MHz and flash can be sped up from 40 MHz to 80 MHz.[citation needed] Success varies chip to chip.[citation needed] ...
