Siemka, od trzech dni nie moge sie uporać z takim problemem. Sciągam sobie ten kod od Mirka:
http://mirekk36.blogspot.com/2013/05/te ... z-lcd.htmldodaje w main.c "#define __UBRR 1666" (SunRiver tak kazał, jak źle to sie nie czepiać
)
A przy próbie skompilowania linker wypluwa mi to:

make: *** [TERMINAL.elf] Błąd 1
Moge tylko dodać że jeżeli powodem mogą być sterowniki do konwertera rs-232 to będę musiał je przeinstalować. Zamiast D2XX od FTDI zainstalowałem wolne (w rozumieniu środowiska GNU
) sterowniki libftdi z repozytoriów. System oczywiście linux.
A tak oprócz tego to inne programy kompilują się normalnie
Z góry dzięki za jakąkolwiek pomoc
