I’m diving into a project with the AMB82 board where I need to grab a bunch of photos and some audio, then shoot the photos over to a server. The server’s going to do its thing and send back an audio file. I’ve hit a couple of snags though and could really use some advice:
Capturing Multiple Images & Selecting the Sharpest: How do I go about taking several images in a row and then sift through them to keep only the least blurry one? I’m guessing there’s some trick to evaluating image sharpness.
Consistent Upload Speed Issue: It’s a bit puzzling, but whether I’m uploading in chunks of 16kb or 32kb, my video (around 8mb) takes the same time to upload, about 7-8 seconds. What could be causing this lack of speed difference?
Playing Audio from SD Card: After getting an audio file back from the server via a GET Request, I’m scratching my head on how to play it. I couldn’t find any examples of audio playback from the SD card. I’ve got a Grove Mp4 Audio player module, but it seems like I’m out of luck since it needs a Software Serial Library that the AMB82 doesn’t support. Any ideas on how I could work around this?
Would really appreciate any insights or pointers you folks might have. Thanks a ton in advance.
