I had a fun time getting http://www.botanicalls.com/code/BotanicallsTwitter_v2.17_OAUTH.zip to work today with SuperTweet. Turns out the 1.0 Twitter API has been deprecated and SuperTweet has completely dropped support. However, the upgrade to 1.1 one is quite easy:
BotanicallsTwitter.pde, LOC 63:
Replace
#define HTTPPATH “/1/statuses/update.xml”
With
#define HTTPPATH “/1.1/statuses/update.json”
Everything else should remain the same.
