CANoe 控制USBTMC连接程控电源代码

以下是使用CANoe控制USBTMC连接程控电源的示例代码：

//导入python-can库
import can

# 定义CANoe连接配置
can.rc['interface'] = 'vector'
can.rc['channel'] = '0'
can.rc['bitrate'] = 500000

# 定义USBTMC连接配置
usbtmc_rc = can.rc.copy()
usbtmc_rc['interface'] = 'kvaser'
usbtmc_rc['channel'] = '0'
usbtmc_rc['bitrate'] = 1000000

# 创建CANoe和USBTMC连接对象
can_bus = can.interface.Bus()
usbtmc_bus = can.interface.Bus()

# 设置程控电源参数，例如设置电压为3.3V
voltage = 3.3

# 发送控制命令到程控电源
usbtmc_bus.send(can.Message(arbitration_id=0x600, data=[0x01, 0x01, 0x01, 0x00, 0x60, 0x00, 0x00, 0x00], is_extended_id=False))

# 关闭USBTMC连接
usbtmc_bus.shutdown()

这只是一个示例代码，具体的CANoe和USBTMC连接细节可能需要根据实际情况进行调整。
