Looking for old code

grondak

I spent the afternoon looking for some code I wrote in 2013. I'm glad I found it. Is a little C++ to interface the Beagle Bone (any) to the Adafruit 16-channel, 12 bit PWN servo driver board- the PCA9685- over I2C. I then tried the old upgrade trick on my BBB. It turned out that the device is an A6 model with only 2GB storage in the eMMC, not 4GB like the Rev C production models. I will probably clean that code up and post it to github once it's all pretty.

  • Every now and then I look up old code. Sometimes I can find it and sometimes I cannot. Where does old code go as I am sure I never delete anything? Maybe it lurks in some long forgotten or unknown directory on the hard drive. Then I can never remember how it works - even though I follow some software engineering practices with structuring and commenting. Sometimes I look through the comments and have a good laugh at my thought processes as displayed. I always remember one small fragment to do with outputting text to a line printer (*yes, it was that long ago) written in Visual Basic (a fun language when you've been used to assembler). I was fighting VB, serial communications and the printer all at the same time. eventually I stumbled on a solution that worked and the comment was along the lines of 'I have no idea why this works, but it does'.

  • I reconnected the board to the BeagleBone and everything works as planned. Makes cleaning up a lot easier!
