Adafruit MM8451 & Raspberry PI SPI错误121与Buster

工作与树莓派和接口与Adafruit MMA8451加速度计板。我正在尝试一个新的安装巴斯特后，我有所有这些工作在伸展。我已经安装了所有最新的库并完成了所有最新的更新。我能够有MMA8451显示使用

sudo i2cdetect -y 1 

在它的正确位置0x1D。当我尝试的例子程序，我通常得到这一大块错误代码:

Traceback (most recent call last):

OSError: [Errno 121] Remote I/O error

最让人抓狂的是，有时候整件事都会奏效。有什么我可以检查的吗?我以前做过这个，所以我认为这是软件问题，而不是硬件问题。我尝试了树莓派3和树莓派4的板，都给出了相同的错误无数次。 问题来源StackOverflow 地址：/questions/59380566/adafruit-mm8451-raspberry-pi-spi-error-121-with-buster
