Totorial 20

Post by Annie » Thu Mar 12, 2009 4:17 am

I really dont mean to rush, just want to know when about the tutorial 20 is available?

I just finished tutorial 19 and can wait to go to the next. 8)

I do know that it takes much longer to prepare a tutorial than to study it, so again no rushing :roll:

Thank alot, Mike

Hello,

I apologize for the tutorial not being up yet.

There are some changes being made company wide and a new project being started, so I have not had much time working on it yet. However, I am still working on the series - just in a different format. (I am sorry but I cannot release more information yet.)

I will see if we can get Tutorial 20 up soon though :)

Hey everyone,

The series was delayed do to another site displaying illegal use of the material provided by the series. This is the primary reason for the delay. I apologize for the wait.

All matters have been resolved however and the series is starting up again. The next tutorial to be released within a week or two. I might decide to cover the DMA along with the FDC do to it being technically better then using the FDC without DMA although both methods are covered.

Sorry for the wait, everyone :(

Hello,

The chapter will be released this Saturday. Sorry for the delay of this one everyone - been busy with other internal projects. I put things on hold so that we can complete the next chapter on time.

We will update the front page of this web site when the next chapter comes out this Saturday.

Again, sorry for the wait :(

Thanks Mike!

I've been spending some time adding to the demo for tutorial 19 lately and I managed to develop a very simple text-based GUI. I think it's pretty neat. Here's some of the interaction with it:

Very basic, but I did it all using classes so it will be easy to port it to new demos :D

By the way, I noticed an error in the sleep() function. The ticks variable is a static int - and because it is static, the function will only work the first time it is called. After that, Get_tick_count() is always greater than ticks, which retains the value from the first time it was called, meaning the current tick count is likely much higher. Removing the static makes it work fine!

Hi Mike
:D
Tutorial 20 was quite interesting. 8)

When can we expect second part of tutorial and demo.

I tried to write a function to read a sector,but it hangs as IRQ 6 was not enabled. however
even when i install int 6 using setvect function,still IRQ 6 was not generated.

anyway waiting for your second PART of the demo

Have you altered the primary PIC mask register to allow IRQ6's?

By default the mask will prevent any IRQs from being called untill we have installed a valid handler and explicitly told the PIC that it is safe to send IRQs
