#182628 - thanks Responding to: ???'s previous message |
I've posted two links. First is my complete project. The source code is divided in multiple files
and an image of the schematics. https://docs.google.com/leaf?id=0BxGcYR4JNBI-ZGVlYWQzN2YtZDMzMi00NDBmLTk3ZDItZGVjMTI0ZGMyOWRl&hl=en_US https://docs.google.com/leaf?id=0BxGcYR4JNBI-NWMzNDc4NDUtZWI0Zi00YWE0LTg4NTQtMTRjMzljMGU2NDg1&hl=en_US (hopefully they are accessible) I have not implemented the keyboard scanning. I have only a basic routine to check that the addressing of 74HC128 is working OK. So I do not have troubles with the keyboard yet. The button that triggers the interrupt is independent of the keyboard itself. I've seen another sample that does a similar job and it is working fine but not in my case. I'll try to extract in another post the most important parts of the source code. I'll try the stack trick first. |
