firmware modifications. We tested today on three different smartphones,
and timings were nowhere near accurate for 2 of them, and one other
phone was reasonable but with accuracy only to about 10ms. This is
actually workable considering the average timing error from manual
clicks is 30-60ms, but the phones with firmware mods have accuracy
between 1-5ms. 1ms accuracy is the best we can get it which is ample
accuracy, which is the case with the new phones.
To test this we use the same switch arrangement for two of the phones we
are testing, and one microprocessor timer with lcd screen that displays
the timings between clicks. The idea is if there is 1ms accuracy, then
all three will deviate in timings no more than 1ms.
Anyway as a general update on progress with the new phones, I'll have
the first completed unit early next week. Once I've thoroughly tested it
to check for rf issues, we'll begin work on a lot more.
