std::set_terminate([](){

  try { throw; } 
    catch(const std::exception& e){ puts(e.what()); }
    catch(...){}

Answer 1

这是因为你传递了一个字符串列表并且它需要整数 - 你想要：

import spidev
spi = spidev.SpiDev()
spi.open(0, 1)
l = [0x20,0x01,0x00,0x10,0x3D,0x04,0x00,0x05,0x00,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00] 
resp = spi.xfer2(l)
