SpinStudio has four sockets "A" through "D", D0-D7 representing Propeller Pins P0-P7, P8-P15, P16-P23 and P24-P31 respectively.

D4 and D5 ( the I2C lines ) are not accessible on Socket "D" - they are pulled to VDD on the mainboard by 4.7K resistors and accessible only as I2C lines on pins 18 & 20 in all 4 Mainboard Sockets
