Topic: Isolating SPI while uploading new code (Read 856 times) previous topic - next topic


Yes I could do that, except the library (FastSPI) used to drive them uses the native SPI port.  And I have no idea how to hack it to use a different port.

Oh, THOSE resistors.  Yeah I get what you're saying.  I need to figure out how to calculate those to begin with.  It's just switching 5V ...

I don't know how to add picture here but i attach a schematic. If we can turn on and off the motor then we can also do that. If there is some thing wrong please let me know.

One more thing calculate all values of resistors RB RE RC etc for switching according to your case. 8)

You intentions and idea my be good, but without a schematic drawing of what you are trying to say, it probably won't get much chance at being implemented.
