Sending Audio Data To The Serial Port?

[shinolife63 Profile]

Hello, first off I feel I should state that I own a Casio fx-9750GII hacked to run the 9860 SH4 OS

Ive been attempting to get a basic audio player working for a while now (All I want to do is generate morse code), the closest Ive come is attempting to compile this:
http://community.casiocalc.org/topic/6428-fx-9860gii-music-player (Which states that it works for hacked 9750's, and has a video proving it)
I set everything up correctly, but when I go to compile, it throws errors like crazy, the author stated that he had uploaded a revised version that he didn't actually have time to test out, which explains all the errors...

Unfortunately, ive been unable to find any source code that would even give me a clue of how to accomplish this myself, and I cant find any documentation either...

If anyone has some example code or addins that would help me accomplish this, It would be greatly appreciated

There is a topic here in the forum with an adaptation of MPoupe audio player for SH4 calculators: viewtopic.php?f=11&t=1440

See if it helps.

Yeah, ive seen that thread, the code posted there is actually incredibly helpful, except I have no idea where to find the 7305.h header file, and the download link that went along with the code is broken
Do you know where I could get either a working version of that dL link or the 7305.h header???
Thanks ^^

I found the 7305.h file here: http://www.omnimaga.org/casio-prizm/aud ... tach=11926

I do not have the compiled file, but with 7305.h and the source code, you should be able to compile it.

Ugh, its still not compiling correctly, I have the 7305 Header file in the same folder as my project, like normal, and I have my 8-bitunsigned "TEST.wav" file in the directory as is instructed, but when I go to compile, I get the following error:

You need to define the syscalls for serial communication, with a syscalls.src file: viewtopic.php?f=11&t=1557#p13320

Wonderful! My code "works", it doesn't throw any errors related to syntax or me screwing up in general, but now it throws:

From what ive gathered from: http://www.casiokingdom.org/calculator-forum/index.php?topic=527.0 and http://community.casiocalc.org/topic/3724-clearingupdating-buffers/, I need to optimize my code, but Im not sure what data types are interchangeable without breaking the whole program, anywhere you might be able to point me to for that?

Reduce the use of global variables, t. i. variables, which are declared outside of any function and without "const" or with "static".
Inspect the map-file to find variables, which are stored in B- or R-segment.
