News - SparkFun Viking Funeral | about 9 months ago
How about you burn an effigy and make the obsolete boards available first-come-first-served at a discount? Obsolete parts are still useful, as any Maker knows!
Tutorial - Lessons from Rebuilding Illumitune | about 11 months ago
Nice job — thanks for the writeup!
For the 38kHz, I’d have been tempted to make a single 38kHz generator (maybe a PIC12F683 controlled by a 50ppm TTL oscillator), and use an AND gate on each LED. That way, you could send logic levels to the AND gates and get either zero or 38kHz out for each one, without worrying about keeping the code length deterministic for each LED. (I’ve done more than enough counting of clock cycles in PIC assembly; there are a lot more fun aspects to spend time on.)
Product WRL-10559 | about 11 months ago
Check your baud rate and settings on your PC. I think it defaults to 115200, N, 8, 1.
Product WRL-10559 | about 11 months ago
WOW — that was easy. Connect 3.3VDC and ground (I put a couple of decoupling caps on the breadboard anyway), connect a ‘scope to the TX output, pair your Bluetooth device with the module (PIN is 1234), and watch the data come in. Very nice!

Will the IOIO ship soon? Thanks.

Very cool! This solves a major problem (GPIO) for a research project we’re working on. Any idea when the boards will ship? (I backordered one today.) Thanks!
Product RTL-09891 | about a year ago
It’s up and playing nicely with a PIC16F887 (although I’ll be moving to a faster MCU soon, because reading data from this thing with the MCU running at only 4 MIPS is like trying to drink from a fire hose, even at the default 5Hz.) Caveat programmor: the default baud rate is 57600/N/8/1, not 9600/N/8/1 as stated in the datasheet. (It has to be.) It runs on up to 4.2V, so I have it running from one of SparkFun’s Li-Ion batteries. The GPS/PIC/LCD combo draws about 40-50mA with the backlight off. Not bad!

Same here — a 4ms positive pulse, every 4.1 seconds or so (hard to tell exactly with this old scope). It doesn’t respond to the configuration program anymore (although it did before). Maybe it’s gotten itself into some sort of no-output mode? If I figure out how to wake it back up again, I’ll post here. In the meantime, if anyone has any ideas, please post!

Finally ordered some of these, and tested the first one today. This thing is great — a real 3.3V 5V “Easy Button.” One minor quibble is the pads could be made a bit larger for ease of soldering — but I managed okay anyway. Definitely recommended.

This board is a great example of why SparkFun just “gets it.” You just know they’ve come across this problem themselves, got frustrated with having to solve it multiple times, and came up with a solution. Rock on, guys!
