Hi board
(so many of my posts begin like this):
"I recently hacked a resistive touchscreen"....
The underlying method requires a loop which sets one axis to 5v (digitalWrite, HIGH) and gnd (digitalWrite, LOW), while the other axis is read. The axes are then inverted. this gives me continuous X-Y axis readings and works really well.
I am now attempting to implement a DIY solution, using a similar method: rows of copper fabric strips, a sheet of Velostat, and columns of copper fabric strips. My question is one of feasability: should I expect similar functionality using the same method? I'm hoping to set columns to 5v, rows to read, then invert and set columns to read and rows to 5v and then loop. Would this allow me access to continuous X-Y data? Someone suggested a 'new' method of: fixing rows to gnd/read and cycling through each of the 5v columns one by one (not too sure how to realise this in code), but would the above method work too?
This question was referred to in a different but related post; I'm sure this doesn't infringe double-posting rules.
thanks all
Brendan
