First, I would like to confirm that the usb port works like I think it would. Here is a picture of my current setup: http://img134.imageshack.us/img134/2884/photo0015zl.jpg. Will this USB port work as attached with the SpO2 board attached? Will it work without the SpO2 board?
So far I have tried examples/tests from the CSL with no success. Specifically I tried the example
“CSL_USB_DmaExample” but I never received any interrupts. I tried plugging the SD card reader into the board (in the above setup), and I also tried plugging the 5515 EVM into my computer through the same port, no interrupts generated either way. I did this with the SpO2 board taken off of the 5515 EVM. Is there a way to make the USB port do what I want, or even better, a predefined way to use the USB port to write to the SD card?
I have also tried examples in the CSL, but even if I can use this library to write to the SD card there are still problems. The SpO2 code appears to have been written using a subset of this library, and this subset has been altered, causing the CSL library and the SpO2 projects to be incompatible. It would help to know more detail about this relationship between the libraries, and if they truly aren’t supposed to be compatible.
Thanks for any help you can provide.
