You may be facing the same thing I did using the solderless breadboards and SPI.
Check this post of mine:
I think I found out what was happening - the capacitance of the breadboards are wrecking the signals. See my other post on this: viewtopic.php?f=45&t=11446&p=54175#p54175
Hope this helps.
Regards to All.

But i am having exactly the same problem in both boards, with and without breadboard
But did you BASIC is getting STACK CRASH too ?

I would download the lates Basic build again, re-flash, just to ensure you do not have a corrupted file.
If still having difficulty, try running it using the DEBUG function. I have found if it works in debug but not without, its a timing issue somewhere.
You also have the ability in DEBUG to slow down the execution which could prove helpful to see where your program is just before it blows up.
Regards.

Hi,
Debug can't solve my problem!
I get the same problems in the both modules. With protoboard and without.
Please, burn there! Here the code that i am testing!
Thanks for your Help!
Code: Select alltft.setup(16, 4, 1)
tft.touch.setup(15)
spi.setfrequency(100000)
bar1 = tft.obj.bar("RPM",200,0,120,30, 2, 65535, tft.rgb(0,25,255))
bar2 = tft.obj.bar("TEMPERA",200,50,120,30, 2, 65535, tft.rgb(0,25,255))
bar3 = tft.obj.bar("VELOCID",200,100,120,30, 2, 65535, tft.rgb(0,25,255))
bar4 = tft.obj.bar("AIRFLOW",200,150,120,30, 2, 65535, tft.rgb(0,25,255))
bar5 = tft.obj.bar("POSITION",200,200,120,30, 2, 65535, tft.rgb(0,25,255))
