Is the sale already over? I only see 19$ in the cart. edit... nm apparently if you aren't logged in you only see the $19 version.

Need video? EVE FT800 chip from FTDI that was recently released and someone is making a library current for the gameduino 2 that is currently in kickstarter. The eve click that I linked above is only 3.3v compliant unless you add a level shifter but that tiny chip acan do some awesome LCD...

Which just so happens to be the chip i'm currently working with!! Freakin love the 1284p chip! I was currently using the pololu avr isp v2 but not really liking it that much. Would rather use my nano as isp than use that thing. It pretty much gives you almost no detailed info on burning...

I found this which seems to be a avrisp mkII clone that can do both xmega, mega, and tiny but also includes a logic analyzer that can support 2Msps? Never having having a logic analyzer, curious to how useful that could be? At some point I need to buy myself a oscilloscope and other stuff... but...

Bigpilot probably a lot more so than the raspi! And I myself have 3 teensy 3's and a few teensy 2++!! Ever since I've found pjrc's kickstarter, I've become a huge fan. I've never liked the arduino shield/package size and think it's a wasted board space! If they changed their package size to...

found this EVE Click which is a 3.3v compliant FT800 break out board with lcd connector and audio amp... Wonder how hard this would be to use on the teensy 3.0?

http://www.kickstarter.com/projects/2084212109/gameduino-2-this-time-its-personal WOW why is that awesome little chip not added to the arduino by default!!! seriously the FT800 chip is a powerfully tiny gpu!!

Man why is there very few options for outdoor lcd's?

I cannot wait till we get teensy++ 3.0!!

Paul, you stated it's bright... would you say it's good enough for outdoors/sunlight?

And just ran it with uint32_t and works fine. Thank you sir!

Well I'll be damn! I tried using 16L before but that didn't work which I assumed was the same but I guess not. Does it have to be unsigned long? or can I substitute uint32_t ?

It's on teensy++ 2.0

Ok, I'm getting royally confused at this point.. So I pass my 32bit color from processing to the arduino fine. I disassemble the 24bit color hex into it's separate rgb bytes and properly store it in EEPROM. After a restart I have it pull data from eeprom and reconstuct the 24bit hex and put it...

any update to this? I have the 2.7 oled I would like to get working on my teensy 3.

Found the issue, seems to have been the usb cable itself that's causing the issue. Replaced and seems to be working fine now. Just no clue why a usb cable would be causing anything over 4k flash to be corrupt but anything under to work fine.

I'm getting a weird issue with a new teensy I ordered. I can upload the basic blink hex no problem, but anytime I upload anything larger than 4k flash space and I get an error on the teensy loader saying download error. If I press the reset button it causes the teensy loader to lock up and hang...

Well I broke down and decided to code the framework for breaking the 24bit hex down into it's RGB and storing those and rebuilding back to 24bit when used in the color array.

I could split the 24bit color into it's R/G/B counterparts, however with the amount of color I have to store, it makes it a huge headache to keep track of 3 address's per color than 1 address. I'm storing 8, 10 frame 4x4 color matrix's that is user programmable. If I stored it as 3 8bit colors...

Well tried and while some works getting corruption on last variable in the array somehow and every once in awhile it doesn't update correctly.. but that may be due to the way the eepromex library's updateLong function works.

I'm currently using the EEPROMex library to store Longs in eeprom. However even with 4k eeprom on the bigger chips I will run out of space quickly storing user color codes. So comes my conundrum of storing data. uint32_t and longs are 32bit variables but I only need 24bits of that... with the...

LOL, so it must be sending the DTR... why don't they give you an option to disable that part? Would have saved me about 4 hours scratching my head last night on why my crap was getting wiped.

http://playground.arduino.cc/Main/DisablingAutoResetOnSerialConnection Found this.. so it is resetting the arduino on serial close. Ugh so I'm going to have to eeprom all this data quickly before I close the connection.

I'm having an issue with serial data getting magically wiped after you close the serial monitor window. So if I open the serial monitor window and type in 2912312 the test value gets updated correctly. If I close the serial monitor window and reopen it... it magically gets swapped back to...

I have a project that is coming near to being fully developed and a distributor already wanting to buy 1000+ units... My question to you sir... is who do you use for pcb/assembly? Itead stated they can, but not entirely sure I want to go with them. Do you have a group you specifically goto for...

I know the ws2811 is a beast, however it's 5050 package... man if only they made a slightly smaller version. Anyone know if they ever plan to?

#include <XBee.h> XBee xbee = XBee(); uint8_t payload[] = { 255 }; Tx16Request tx = Tx16Request(0x6556, payload, sizeof(payload)); void setup() { xbee.begin(38400); } void loop() { xbee.send(tx); delay(1000); } I have a coordinator and end point. I'm using that code on the end point...

I would like to build a small pcb with 2 leds per circuit and have them linked in series. However I'm not finding any schematics online showing what is directly needed for wire. The two schematics I've found stated you need a resistor on VDD and a cap on VDD to gnd.. but no mention on size of...

Makes sense why fpga's are mostly used in driving larger lcds and such. Heck I'm just glad my teensy 3 can handle the 3.2in I'm using now.

Was reading the wiki page on the r-pi and it's a broadcom chip with arm 11 and their vcore 3 gpu. Seems to be a all in one chip compared to the micro controllers. So then you would agree that with the R-PI having to go through a software layer (aka the linux kernal) it causes the gpio to be...

I'm new to hardware and also semi new to programming, so bare with me. I'm confused by all the different processors chosen by all these micro controllers. arduino uses atmega teensy uses atmega and now arm cortex (which from what I know is an actual cpu?) pi uses arm 11 (<-- but I assume the...

I have to agree this makes writing my library much easier now that it's in a c++ editor with my project. It just sucks the arduino IDE can't have both open at the same time. But hey can't complain considering all they've done. Including what you have as well!

ugh.. no wonder my code went from 35k to 58k using snprintf....

I'm not quite sure what that actually does.. besides gray out the window and make it non editable. What editor do you use to write with then? hmm notepad++ seems interesting

Started on uno, ended up going to nano and now teensy's. I have become a huge fan of working with the teensy 3.0 but as much as I love working with it and c++, the arduino IDE seems to be the crutch in going forward. Lack of real support for multi tab project including building libraries at the...

Already ordered from parts express. Etchael, those aren't just speakers. Those are fully developed products.. not exactly what I was looking for.

Hmm strange... I'll have to double check.. it's weird tho all other colors work fine.. just anytime I fade red it doesn't fade correctly? I mean it's still red, just the level of brightness isn't correct for each level of brightness.

You freakin rock!!

teensy 3.0 arduino ide 1.0.3 teensyduino 1.12 code does NOT matter but you can replicate it with this. 3 files in same directory test.ino test.cpp and test.h test.ino #include "test.h" void setup{ } void loop{ } in test.cpp #include "test.h" test.h is blank. main.cpp.o: In function...

Anyone know of a site where you can buy cheap speakers? 3ohm or 8ohm 1-5watt speakers for project? I find 8ohms all over digikey but nothing really in a decent size for 3ohms

I'm building a class and header file in the same directory as my project file. If I move the .h and .cpp to it's own library directory, it compiles fine. If I leave it in my project directory so that I can edit it easily in the arduino ide as well as my project... I get this...

Anyone having issues using setColor(?, 0, 0); ?? it seems red is having issues at least on my 32WD tft. I can fade in blue and yellow no problem, but when I try red.... it seems the values are not working correctly on red. while(1){ readB(r, b); if (hDir == 0){ hCount+=10...

So, just checked and apparently someone else has already ported utft to teensy3 and a bit better coded than I have..

I am currently working to port this library to Teensy 3.0! I already have it working on the Teensy 2.0++ but figured I could use some more horsepower of the 3.0.. I'm hoping to have this done and tested by this weekend.
