You should strive to run the interface to the chip as fast as possible for this interface. Have you carefully checked all your bit-bang timing on a scope to make sure that it all looks OK? I must be honest and tell that I haven't checked. When first time I had developed the C routine I was more concerned about the correctness of my protocol implementation. It has some _nop_() inserted in some points where I wanted to be sure that all the transitions were executed just fine. Now... due to the fact that my 12MHz 8052 core is significantly slower than the memory I could remove them and speed a little bit the communication protocol. I will make it today. Michael Karas said:
How are you accomodating the 5 millisecond write pulse time of the AT25C1024? With timer based delay. Here I am pretty sure that all is correct. Here is the Atmel link: http://www.atmel.com/dyn/produ...rt_id=3479 at Application Notes section there is something called: USB Generic Implementation Based on HID Class, and http://www.atmel.com/dyn/resou...-1_2_0.zip is the actual link to the sources. |
