  2. Outline • Project Proposal • QT2410發展版 • QT2410 GPIO Introduce • Introduction of IrDA • Protocol Stack • IR Remote Control • Designing process

  3. Project Proposal(1/2) Network Remote House

  4. Project Proposal(2/2) AP Driver • Hardware • RS232 • GPIO

  5. RS-232 Power USB host MMC/SD FOR 2410 CORE Network JTAG QT2410發展版

  6. NAND Flash 64 MB S3C2410 SDRAM 32 MB * 2 QT2410 Core

  7. QT2410 GPIO Introduce(1/2) GPFCON GPFDAT GPFUP

  8. QT2410 GPIO Introduce(2/2) • PORT CONFIGURATION REGISTER (GPACON-GPHCON) • PORT DATA REGISTER (GPADAT-GPHDAT) • PORT PULL-UP REGISTER (GPBUP-GPHUP)

  9. Introduction of IrDA • IrDA 裝置是使用紅外線的LED. 其波長大多是介於 875 nm +- 30 nm之間. • IrDA 裝置其距離約工作在 1.0m . • 依傳輸速度可分為： • SIR115.2Kbps • MIR1.152Mbps • FIR4.0Mbps • VFIR16Mbps

  10. IrTran-P OBEX IrLan IrCom IrMC LM-IAS Tiny Transport Protocol – Tiny TP Transport layer Ir Link Mgmt –MUX - IrLMP Network layer Ir Link Access Protocol - IrLAP Data Link layer Async Serial-IR 9.6 – 115.2 kb/s Sync Serial-IR 1.152 Mb/s Sync 4PPM 4Mb/s Physical layer Protocol Stack IrPHY

  11. IrPHY • 實體訊號層(physical signal) • 為實際的紅外線裝置，資料便是透過它來傳送 • 其發射頻率介於 33kHz-40kHz 之間 • 其傳送資料封包是使用CRC的錯誤檢查碼格式

  12. IrPHY Packet Format 1.152 Mbit/s and the lower rates 4 Mbit/s 16 Mbit/s

  13. IrLAP • 連結存取協定(link access protocol) • 用來提供和維護IrDA裝置間的可靠連結 • IrLAP 提供兩種一般形式的服務 • Connectionless Services • Connection-oriented Services

  14. IrLAP Frame Structure • IrLAP employs four generic types of service primitive • Request • Indication • Response • Confirm 8 bits 8 * X bits 8 bits

  15. IrLMP • 連結管理協定(link management protocol) • Provides multiplexing of the IrLAP layer • Support for multiple application to operate independently and concurrently

  16. IR Remote Control • Low cost solution of remote control • No specific stack • Control signal defined by manufactory

  17. Signal Definition Ex：TOSHIBA TV power on signal Factory：40BF Button ID：12ED  1 0 | 0 1 0 0 0 0 0 0 1 0 1 1 1 1 1 1 | 0 0 0 1 0 0 1 0 1 1 1 0 1 1 0 1 40BF 12ED Start Signal Factory ID Button ID

  18. Designing process

  19. Q&A
