Please try pg35-bin-linux.zip It includes mainly pg-linux-2.2.17, pg-linux-2.4.19 and setenv-pg.sh setenv-pg.sh is for set CPU_CLOCK_HZ Environment --- I used RT-Linux before. If I make a application for other user under RT-Linux, Other user must update user's Linux-kernel-version to same my kernel-version. I think it is not user-oriented, but maker-oriented. So, I made PG under Normal Linux, and got good acuurate timing. -- Merit is user can use the PG code partially in a user program where needs accurate timing. Demerit is cannot stopped by ^C while generating a pulse portion. --- Finally, I'm sorry my poor English.
