We need to add detailed description of sensors and configuration parameters here. Most can be had from GenBoard/InitialConfig page.
GenBoard/VerThree knockdetection HW
Needed for Knock Sensor input:
- R1, R2 Knock Channel 1 (10..22k) (analog signal amplitude gain can be adjusted with these; but also in the digital domain - in config)
- R3, R4 Knock Channel 2 (same as R1,R2)
- R17 1M
- C1 Knock Channel 1 (100nF)
- C2 Knock Channel 2 (same as C1)
- C14 0.22uF
- C16 100nF
- C18, C19 22pF
- Y2 4MHz XTAL (16MHz might work with matching config)
- U5 TPIC8101DW (not in rescue kit! Optional, see WebShop)
C17 is no longer used. (was: 2.2nF, can now be left off)
V3.2: if you ordered knock-kit (in same order as genboard) than U5=TPIC8101DW and Y2=crystal already soldered onboard (crystal missing on a few boards sent out before 20041030.)
