Sparkfun support will be closed from 3:00PM to 4:15PM on April 27th for a company-wide townhall meeting. We will resume regular hours on the 28th.

  • Yeah you are right i meant the protocol, sorta assumed it would be NEC, not a big deal to find out just hoped someone might know. And if it is 38KHz then its not Sony cause thats 40KHz

  • Whats the IR protocol used? Standard NEC, Sony SIRC or what? For those who don’t use arduino/libraries

  • .

  • From the looks of things (had a quick browse) most of it should be alright as long as you are using a similar mcu with RX int enabled ( ISR(USART0_RX_vect) ) the best thing to do is add the .h and .cpp files (rename .cpp to .c) and include stdint.h in avr studio for the use of uint8_t in the .cpp file try a compile and see how it goes. If it fails there is something small Ive missed that you may have to change or another include etc, shouldn’t be to hard in other words because it will come up as an error which is easy to change. I use avr studio 4 for all my programming, and it should be similar to 6, but Ive used a few of the arduino libraries after small mods, and i mostly use the 328P mcu

  • “The HackHD also has a composite video output which can be viewed while it’s recording” Is that what your after?

  • Well technically its not a true ac sine wave with positive and negative half cycles, it can only be a completely positive sine wave because like you said its digital logic which does not go into the negative scale.

  • No.. Varying PWM through the correct filter, and you have a cheap DAC. Which you can use to make basic sine waves.

  • Fantastic little buttons, im always running out, great for reset buttons and to be used for digital inputs either pullup or pulldown

  • The legs bending towards each other are normally closed, when you press the button all sides are closed if i remember right

  • First of all 1 mile is considered to be done in near perfect conditions, basically in line of sight only. Your packet/data would be very “lossy” at this range, but generally you would need to implement your own form of check-sum at that range etc. If the packet doesn’t reach the target, then the sending device will fail to receive an ACK(Acknowledgement of your data being received), and try to resend 3 times, unless you’ve changed it to a greater retry count. It would be a massive struggle to get up to or beyond a mile with this device unless you use several to repeat the signal at smaller intervals like 600~800 yards etc over your wanted distance, or using some form of high gain antenna
