Hello,
I know this group is in polish, and I just can speak english and italian, but I also see this group has more messages about BASCOM and I hope somebody can help me.
I'm using an Atmega128 connected to an AD7843 touch screen controller with SPI interface through PORTF (PF4/5/6/7).
I configured SOFT SPI mode in Bascom, but can't read anything from that controller.
Does anybody know of potential problems with this configuration?
Thankyou.

PF4,5,6,7 are reserved for JTAG. Disable it by JTAGEN fusebit.
As I remember, por F is setting as JTAG by default. Change this setting in "Lock and fuse bits section" in your AVR programmer. Best regards, K.

You can also disable JTAG on PORTF in software. Just set JTD bit in MCUCSR register.
