I am having problems connecting the ground from the adapter of the PS2 to my boe bot via the board of education. It is grounded already or do I need to disconnect it from the red lead and ground it “manually”. Any help would be great from anyone who has used the strategies from John Williams article “Playstation Controller Redux”. Thanks
Not exactly sure what you’re asking for here. Could you post an image or schematic. You are aware the BS2 requires an inverted on one of the lines in order to use the serin command right?
The reference quoted describes bit-banging the SPI communications in basic so that you can send and receive at the same time. If this is the guide they are following for programming the polarity issue might be taken care of in their code… which suggests it might be very helpful for them to post the sections of code implementing their ps2 interface if they want helpful input.
