Skywriter xl - raspberry pi 3


#1

Hi,

Just installed the skywriter xl to my raspberry pi 3.
when running the test.py, I get 9 out of 10 times a (‘Tap!’, ‘center’) or (‘Touch!’, ‘center’) message instead of “swipe”. The coördinates are showing really fast, so detection is fine.

2nd question: Which side should be up? The side with the squares or the side with all the text?


#2

the ‘grid’ is the ‘up’ side. regarding your issue, maybe you are waving too close to the board? try an inch or more away, it may help.


#3

Thanks for your reply.

I’m waving roughly 5-10 cm above the board. Seems that the july update is not implemented in the standard install link?


#4

There is no firmware upgrade for the XL Skywriter, the firmware issued last July was only for the HAT version, if I understand what you refer to.


#5

Indeed, it was an update for the HAT version, but I installed it.

Maybe I’m lying to myself, but the board seems to behave better since the install. :s
I removed the following from test.py:

@skywriter.double_tap()
def doubletap(position):
print(‘Double tap!’, position)

@skywriter.tap()
def tap(position):
print(‘Tap!’, position)

@skywriter.touch()
def touch(position):
print(‘Touch!’, position)

Removing this lets the board better behave. But offcourse, this is not normal.


#6

In meantime I’ve tested the board further… The board keeps behaving very strange. Since today it can not anymore recognise any gesture (left, right, up, down, etc…) I’ve followed a solution on [SOLVED] Fullsized Skywriter Problem, but this didn’t help.

Any suggestion? (It does give me x,y,z values in the test.py file)

Furthermore, the test.py script stops regulary to go in a loop about 1.1.18;p:Hills Got firmware info. Why does this happen?


#7

Anybody? Would expect a working board for this kind of money :’(


#8

The usual advise apply… contact support@pimoroni.com. Please do not apply the HAT firmware to the replacement, it is not suitable.
