  • Stepper-motor-drive-source
    步进电机28BYJ48型四相八拍电机,电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时,它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次,也就对应转子转过一定的角度(一个步距角)。当通电状态的改变完成一个循环时,转子转过一个齿距。四相步进电机可以在不同的通电方式下运行,常见的通电方式有单(单相绕组通电)四拍(A-B-C-D-A。。。),双(双相绕组通电)四拍(AB-BC-CD-DA-AB-。。。),八拍(A-AB-B-BC-C-CD-D-DA-A。。。)(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)

  • C8051F060-AD-UART1
    C8051F060 自带高速AD进行数据采集 可达100兆采样率 并切缓存与片外ram 并把采集数据通过串口发送给PC ( Data Acquisition example for C8051F060 Description: This example illustrates the use of ADC1 and the DMA to acquire and store data. It is intended for use with the C8051F060 target board in the development kit. // This code measures a signal at the AIN0 input with the 16-bit SAR ADC0. // The data is sampled at a rate of 100kHz. ADC output data is transferred to XDATA memory space using the DMA. // // With the EMIF configured for off-chip XRAM access (on the upper ports), this code moves the ADC data to the C8051F060TB target boards s SRAM device. // Once data acquisition is complete, the code then prompts the user to press the P3.7 // button on the target board when ready to receive the data via the UART0 serial port. The TB features an RS-232 transceiver and connector, so the data can be transferred // to a PC via its serial port. // The code is set to acquire up to 32768 samples (for 64kbytes of data). The SRAM device - can accommodate up to 128kbytes, )
