[FUGSPBR] Instalando um Display LCD 16x2 no Free

[Alexandre Nuernberg]

voce usou o LCDproc? /usr/ports/sysutils/lcdproc/

meu display usa o driver HD44780
baixei o source da http://lcdproc.omnipotent.net/ compilei o lcdproc com
suporte a todos os drivers:
./configure --enable-drivers=all
make
make install

ele aceita todas as opcoes, mas qdo vou rodar com o driver correto (HD44780)
da core dumped
 LCDd -d HD44780
Bus error (core dumped)

com relacao ao arquivo ppilcd.c vc compilou-o diretamente ou tem que
recompilar o kernel.,

pois no meu 4.6 nao tenho nado no diretorio /usr/share/examples/ppi
somente no /usr/src/share/examples/ppi/ppilcd.c e qdo tento compila-lo da
erro

cd /usr/src/share/examples/ppi
