SmartThink Remote System Team Cyclops Justin Bewley Winter Jojola Florence Manega Paul Roberts Denknesh Temesgen Introduction SmartThink Remote System Designed for people with disabilities Aids in performing everyday tasks Controls television set Controls objects attached to SmartThink adapters ? Conceptual Design Infra Red transmission Line of sight + 10 degrees Learns Pre-programmed IR codes ? Incorporates an LED array attached to a target CPU LEDs correspond to state of FPGA state machine ? Conceptual Design continued… Head mounting Digital compass Imitate head motion Inclinometers Levels; determine vertical angle of sight Description of working system Overview Block Diagram Motherboard Micro-controller Schematics continued Schematics continued FPGA - Spartan State Machine IR Transmission IR Reception Television Set Adaptor to go on other devices, i.e. fan Regulated by 120Vac. Processor checks for IR codes Relay switches power flow to peripheral device Sip/Puff Switch Memory Map Software Breakdown Interrupt from XCS10 Serial Data Out Serial Data In Find open slot for data Interrupt from XCS10 (State is latched to data bus from XCS10) Processor reads in state from data bus Based on state, read in from appropriate flash memory preset location (SPI) Send data across Serial TX until signal is complete (SCI) Send data out serially Serial Data Out(memory addr. Z) For(I = 0; I IR signal length; I++) Gather memory byte from Z+I Send data along serial line Serial Data In(void) For(I = 0; I IR sig. Len; I++) Put memory byte from serial line into location $TEMP+I Find open pre-selected data space-Y If(Y == ERROR) Memory space all used up, flash ERROR Zero out memory space @ Temp Else, move memory from TEMP to Y Find open data space(void) Based on config byte at 0x0000, find open space in memory for new code (0 = mem in use) (1 = mem open) If no open space, return ERROR If there is an open space, return which space and declare the space used Parts List Mo
