P8.P23 are routed as differential pairs and can be used in odd-even pairs as LVDS input or TMDS/HDMI output
P24.P31: general purpose single ended FPGA I/O normally mapped to propeller P24.P31 P16.P23: general purpose single ended FPGA I/O normally mapped to propeller P16.P23 P8.P15: general purpose single ended FPGA I/O normally mapped to propeller P8.P15, or in odd-even pairs used as analog input (4 analog in total) P0.P7: general purpose single ended FPGA I/O normally mapped to propeller P0.P7 This makes more sense to me than adding the USB directly on 40P14
There is DIP14 socket slot on the DIP40 module itself, one of the add-ons would be microUSB UART and power add-on. MicroUSB is fragile, no matter how you glue it or try to protect, it will be teared off the board sometimes. If the design expects 3.3V power from base, then it is safer and easier solution.
Providing power from propeller to base would break that, and require special circuitry and switching to choose where power is coming in and going out. it expects power from the base and not other way around. Of course the production files needed to duplicate the hardware will be available as well, so that the same design could be replicated without the need to use AD.ĭesign tools to compile the P1 verilog are free, but not open sourced.Īs of on-board micro-USB, well it is not planned directly, from following reasons: As of AD vs KiCad, well I do what I can, and that includes design files in original format. The FPGA tools as example are not, so there is not possible to be ideal in that sense anyway. If you read the definition carefully then it says: "ideally the tools would be open source ones" there is no requirement that they are and in many cases they can not be. Certainly not useful to non Windows users. Open sourcing AD files seems kind of pointless. AD is a closed source, expensive, Windows only program. I have to question the choice of Altium Designer. If it could be powered and programmed from an on board micro USB port that would be great.
