#83173 - Tips and Tricks.....Andy Responding to: ???'s previous message |
Thanks so much for the constructive comments.
Quite frankly those typedefs are the result of the guidelines given by M.J.Pont in his Embedded C book. I somehow liked the concept and thought will use it. In fact after posting the code I realised that I forgot to mention the MCU and Clock details - it was a 89c52 with a 12Mhz crystal. The points about the delay are quite obvious and I never used this delay after the initial stages. I had modified the code with a interrupt based delay and also used the Busy bit of the LCD in the next code that I wrote - worked fine! The only thing that went over my head was this You should define cntr_1, cntr_2 as volatile - otherwise the compiler may completely optimise this code away! Could you revert on that ? Thanks again.
