Revision as of 18:43, 7 October 2009

The Q7 is basically a bigger-screen version of the Q5, with an extra USB host port added and no internal bluetooth.

There are images of a disassembled Q7 available at http://www.jiongtang.com/blog/html/smartq5/smartq7-apart-images.html

Components

Connections

The S3C6410 SoC has 3 SD ports, one has the iNAND connected and the external SD port, the other has the SDIO wi-fi chip connected. (unsure whether using these 3 at the *same* time is possible due to GPIO sharing)

The audio codec is connected through I²C (control, address 0x1A) and I²S (audio transport).

GPIO ports

  • AT88SC: N0 -> SCL, N1 -> SDA (emulated I²C bus)
  • LCD panel: M0 -> LCD enable, M1 -> SCL, M2 -> SDA (emulated I²C bus)
  • backlight: F15 (== PWM_TOUT1)
  • Speaker: K12 -> en-/disable
  • Headphone: L12 -> insertion detection
  • Video amplifier: K13 -> en-/disable
  • Wi-fi: K1 -> en/dis-able, K2 -> reset
  • System power: K15 -> power control, L14 -> system power hold over 5 second time, pull up K15 (?)
  • Charger: L13 -> DC insertion detection, K4 -> charging status 1, K5 -> charging status 2, K6 -> 0: 200ma 1: 860ma
  • External SD card: K0 -> write protect detection
  • USB: L0 -> USB voltage en-/disable, L1 -> USB host 5V en-/disable, L10 -> USB host over-current protection status, L11 -> USB OTG over-current protection status, L8 -> USB OTG enable
  • LEDs: N9 -> green LED (?), N8 -> red LED (?) (note: set 0 to enable, set 1 to disable)
  • Hardware buttons: L14 -> power button, N4 -> button 0, N3 -> button 1, N2 -> button 2, N15 -> button 3, N12 -> button 4
