Waveshare Spotpear 3.2 (A) - no touch input - Raspberry Pi Forums
this question has no doubt been asked elsewhere, have been searching weeks answer.
i'm using waveshare spotpear 3.2" touchscreen.
screen works fine, but touch not.
i'm designing light , sound show local museum
(full detail here: viewtopic.php?f=41&t=116208)
i've attempted provide useful information can solve issue.
have reseated ribbon connector on back, , checked miss-wired pins on crossover cable.
tested directly connected pi without ribbon.
raspberry pi b+
raspbian 4.0.7+
ds3231 rtc on i2c 1
3 way multiplexer board
breakout board
4 channel relay card

these only made things worse, set me not having functional screen.
i'm going factory supplied image, , transferring code , backup files across that.
kernel version quite old - it's 3.18.1 or something.
screen fails work when upgrading version, have found @ above link, below commands may prevent that: plan attempt upgrade first thing, , post results.
