电机测速(有霍尔+磁钢或红外反射对管+黑白码盘做该实验)-Motor speed (with magnet or Hall+ tube+ black and white infrared reflective code wheel to do the experiment)

单片机STC12C5404 本程序为无刷电机48V30A三相6拍智能版本-PCB上Q孔P14口对地后开电门锁系统将自动进入64种相序接法自动识别功能。带有AD霍尔数据采集鉴相，STC无刷清单及说明，STC做板文件，STC_sch，STCt贴片图等等全套文件，非常有价值。-MCU STC12C5404 This procedure take intelligence of 48 v30a three-phase brushless motor 6 version- P14 hole on PCB

霍尔传感器方波程序，带OS，电位器调速，STM32F1驱动(Holzer sensor square wave program, with OS, potentiometer speed control, STM32F1 drive)
