finally I get - maybe in a week from now - some time to spend on the AXO board.
I already stated that my purpose with the board is to learn the ropes of programming the STM32 for audio applications, so I plan to leverage the written code and study it to learn how to deal with the controller and its peripherals.
Last time I managed to compile the FW as makefile project using gnu tool chain under Eclipse, adding some very stylish LED blinking of my own
Now my goal is to start working on basic filtering actions, with the easiest filter being a straight connection between IN and OUT.
This involves sending to and getting back data from the DAC/ADC, through SPI interface.
Since I wouldn't really know where to start with this, I thought I would put a simple patch together using the GUI, where a single in and out audio blocks are connected by a wire, and then try to embed its code (which is available in the file patch.cpp) somehow in the main of the FW.
However, I am not able to do so because it looks like the patch loading mechanism is different than a simple loading of functions...At least I wasn't able to figure out the proper actions to follow.
Can anyone point me in the right direction?
Alternatively, what is the simplest form of (DMA) transfer to and back from the ADC/DAC via SPI, using AXO?
Thank you in advance for any hint
