i'm experiencing some problems getting the touch functionality of the pitft to work. I've got the same problem with non-working touch and unknown chip id as described in this thread: viewtopic.php?f=47&t=47326
Dmesg says:
Code: Select all
[ 12.837101] stmpe-spi spi0.1: unknown chip id: 0x0
[ 12.847278] stmpe-spi: probe of spi0.1 failed with error -22
Code: Select all
pi@raspberrypi ~ $ lsmod | grep stmpe
stmpe_device 5628 0
Code: Select all
pi@raspberrypi ~ $ ls /dev/input/tou*
ls: cannot access /dev/input/tou*: No such file or directory
I already triple-checked the solderings (even cleaned & resoldered) and checked conductivity - eveything seems fine. Several reboots (cold and warm) didn't change anything, too.
Here are two pictures of the solderings:
Do you have any suggestions for me?
Thanks and Best Regards,
Felix
