How-to get your codec on the PCB:
1. Find an electronics wizard as awesome as James
2. The wizard will usually have a soldering paste in his fridge
3. The wizard will bring some of this paste out, and place it on the PCB with the precision of a surgeon
4. Bake the mounted PCB in a solder-reflow oven
5. Do a visual inspection to check contacts
6. Check for shorts using a multimeter
7. Solder on header pins (that’s what I got to do!)
8. Breadboarding next!
Now that I have had my fun with hiding away the datasheets, the goal for tonight is to actually push through and complete the codec part of cape. 32 pins and a ground pad: lets see how this goes!
I2C: connecting SCL and SDA to BBBlack’s P2.19 and P2.20, respectively
Mics: (making room for our binaural mics!)
On looking to separate the analog and digital ground planes:
If this the community I belong too, I’m okay with that 🙂
[ Bootstrapping BBBlack ]: There are four methods to connect to the board: USB Serial, FTDI Serial, TCP over USB and Ethernet.
For some reason, installing the drivers didn’t seem to get the connection up and running. I kept re-installing the drivers, restarted my computer, nothing. I went into network settings and removed the “not configured” BeagleBone Black connections (I had ended up with two of these!) — still nothing. I powered off the BeagleBone and brought it up again, re-installed the Network driver, and boom. Its coming up now. So we can test I2C while running Eagle in an adjacent window. So much for convenience 🙂
This is probably the fifth LED flash of this semester. mBed, R-Pi, Arduino Uno, ezDSP C5515, and now BBBlack. I also borrowed an Edison and we can get to some LEDs coming out of that next? No…enough platforms for now. FPGAs should be coming next anyway!
Fun fact: the curious http://192.168.7.2 address only responds *after* BBBlack’s drivers have been installed. Ha. I liked assigning R-Pi’s IP myself, lets try it on this as well.
I’m really happy about using USB and not the ethernet cord at this moment.
Anyway, Cloud9 looks very interesting! mBed’s cloud based IDE shows up in a new form…
And the LED is flashing alright. I’m just a bit terrified about going from this LED flashing to programming a C5515 through this same board. Well.
