Command code
Command code
6.2.20
6.2.21 RHYSx: Hysteresis ratio for each channel (read/write enabled only in setup mode)
0x43..0x66
0x44..0x67
RTHRx: On-judgment ratio for each channel (read/write enabled only in setup mode)
Used in teaching.
Sets the ratio of the quantity of judging change (THRx) to the measured value observed in teaching
with an unsigned 4-bit integer. (Refer to “7. Teaching” for details)
Only the lower-order 4 bits are valid. If the other bits are written to, they are ignored.
If the measured value changes by ΔA due to a touch during teaching, the quantity of judging change
that is newly set in teaching (THRx) is calculated as:
Quantity of judging change (THRx) = ΔA
For example, if RTHRx = 10, the quantity of judging change (THRx) is:
THRx = ΔA × (10+1)/16
Used in teaching.
Sets the ratio of hysteresis (HYSx) to the measured value observed in teaching with an unsigned 4-bit
integer. (Refer to “7. Teaching” for details)
Only the lower-order 4 bits are valid. If the other bits are written to, they are ignored.
If the measured value changes by ΔA due to a touch during teaching, the new hysteresis that is set in
teaching (HYSx) is calculated as:
Hysteresis (HYSx) = ΔA × (Hysteresis ratio (RHYSx))/16
For example, if RHYSx = 2, hysteresis (HYSx) is:
HYSx = ΔA × 2/16
