If only X and Y coordinates are to be measured, then the conversion process is complete.
Figure 51
shows a
flowchart for this process. The time it takes to go through this process depends upon the selected resolution,
internal conversion clock rate, averaging selected, panel voltage stabilization time, and precharge and sense
times.
The time needed to get a complete X/Y coordinate reading can be calculated by:
where:
If the pressure of the touch is also to be measured, the process continues after the X-conversion is complete,
measuring the Z1 and Z2 values, and placing them in the Z1 and Z2 registers. This process is illustrated in
Figure 52
. As before, this process time depends upon the settings described above. The time for a complete
X/Y/Z1/Z2 coordinate reading is given by:
t
coordinate
= time to complete X/Y coordinate reading;
t
PVS
= panel voltage stabilization time, as given in
Table 11
;
t
PRE
= precharge time, as given in
Table 18
;
t
SNS
= sense time, as given in
Table 19
;
N
AVG
= number of averages, as given in
Table 9
; for no averaging, NAVG = 1;
N
BITS
= number of bits of resolution, as given in
Table 8
;
f
conv
= A/D converter clock frequency, as given in
Table 10
