#148762 - I've found the opposite! Responding to: ???'s previous message |
As for checking lcd busy - that requires another port pin! Then what happens when the lcd fails? The code gets stuck in the wait loop unless you check for a timeout. Then what do you do if it times out? I got caught by this years ago, so now i don't bother with checking the busy status - just a fixed delay. If the lcd fails - the code keeps going. I've found the displays I've used over the years are quite consistant with timing. So choose your poison!
As for binary number in 'c' - some compilers allow 0b for binary. I'm sure someone can inform as to the standard in this regard. |
