quisk-kc4upr/kc4upr/IO Hat/IO Hat.sch-bak
Rob French 94267ab4b6 Added the hardware and widgets files (sadly, I 
forgot to store their history).  Also, added
some hardware schematics showing the workings of
the interface hat for the CW key (and the key
line to the RS-HFIQ).

ID_SD and ID_SC PINS:\nThese pins are reserved for HAT ID EEPROM.\n\nAt boot time this I2C interface will be\ninterrogated to look for an EEPROM\nthat identifes the attached board and\nallows automagic setup of the GPIOs\n(and optionally, Linux drivers).\n\nDO NOT USE these pins for anything other\nthan attaching an I2C ID EEPROM. Leave\nunconnected if ID EEPROM not required.
