MCP2210的python中出现错误

Question

我试着用Python上传下面的程序，以便与ad5592r进行SPI通信

handle0 = c_void_p(Mcp2210_OpenByIndex(vid, pid, index0, path0, 
byref(pathsize0)));

但是我在运行程序时遇到了一些错误。请帮忙解决这个问题。你知道吗

pgpioDir = c_ushort( 0x00000140)
ret_code=mcp2210.Mcp2210_GetGpioPinDir(handle0,pgpioDir)

if ret_code != 0: #E_SUCCESS
    print("Unexpected error code returned: ", errors_dict.get(ret_code, ret_code))


else:
    print('i')
    print ("MCP2210 #0 manufacturer descriptor is: ", pgpioDir.value)
    print('k')
