I need advice .
It is about digitally controlled fuel gauge.
You have TF bicycle, digital fuel guage chip + Battery M chip monted on battery pack , both chips have serial ports to communicate with host DSP processor. Fuel guage is dead, you want to replace it. After replacing , would host processor be able to communicate with replaced chip without running some kind of sofware? Simple would host be able to handshake with new chip which didn`t communicate with it before?
Any electronic guru out there?
