To make the RS232 work on the 8300DSK, you need to add the level-translating
IC and 5 capacitors as noted in the DSK schematic on page 24 of the PDF (http://e- www.motorola.com/files/dsp/doc/user_guide/MC56F8300DBUM.pdf). The schematic references a Sipex SP3232, but the Maxim MAX3232 appears to be a pin for pin replacement. I've not done the modification on this board, but I have successfully done it on the DSP56F800DEMO board (with the Maxim part) which has the same RS232 block as this board. --david --- In , "Nicholas Singh" <nicsingh@y...> wrote: > Hello, > > Seems as though this board is missing the PCB-mount DB9 serial port > as well as what appears to be some RS-232 logic level shifting IC(s) > and analog parts.
