I am new and trying some of the c51 download files. I cannot get a counter to work. If I use the peripheral/ports dialogs to set / clear p3.4 or p3.5 no changes in THx or TLx. If I use prdefined tool box buttons, nothing. But if I use the timer dialogs to edit THX or TLx fields then I get some results in variable that read these registers. Has anyone else tried these downloads and had similiar problems?
