Re: YORK A/C Checksum unknown
Select LSB8 format from the powertools menu & decode all signals again Using the checksum calculator under Power tools menu. Set to ignore last byte checked a few signals and they come up as XOR If you XOR every BYTE you get 00 to generate the checksum, XOR all bytes except the last one and plac...

@joker_mkd
Thanks for posting the field descriptions & session file.
I will have a look and come back shortly...

Re: 555 in astable mode (carrier frequency)
Some options
1. Look for the example of 'softPWM' on our blog.
2. Just copy the method used in IRremote or TimeOne for generating PWM. (you dont need to include the full library)
PWM methods will be better. Any PWM inaccuracy of less than 1kHz is not material for your application.

Re: 555 in astable mode (carrier frequency)
Yes using the timer on your MCU is the best approach - assuming it has a crystal. You will not get exactly 56kHz, but 55.x is close enough. You shouldnt be getting 66kHz spikes - so there must be something wrong with your setup, code wiring etc. Did you try the Timerone arduino library, which whould...

Re: 555 in astable mode (carrier frequency)
I just had a look for a 56khz crystal and it seems they are not available - so you will have to proceed with the 555. I assume you dont have any spare pins avaialble on your MCU, but $2 for an arduino clone with crystal is hard to beat! Unfortunately the image didn't make it - I will upload one belo...

Re: 555 in astable mode (carrier frequency)
Hi James We designed a similar 38kHz circuit for our BeamIR project recently and got it working OK. In the final version we changed to a crystal circuit. I suggest you change one of the resistors for a Potentiomer so you can adjust or tune the frequency. However, unless it is a critical or long rang...

Re: HeatpumpIR Arduino library to control heatpumps / AC
Hi Toni
Great library - thanks for sharing
PS:
Unfortunately, we have to process registrations manually on the forum, due to the absurd level of activity of spambots...which is a pity....hence the delay

Re: Panasonic AC ir CRC
The checksum is the last byte in each part of the IR signal and is calculated by the SUM of all the preceding bytes in that part.(do not include the last byte in the calculation) There is a very good explanation of reverse engineering the Panasonic Air Conditioner (Aircon) Infrared signals here, inc...

Re: AC signal troubleshooting (II)
Actually, the protocol is already supported in AnalysIR as DAIKIN280AC
The issue was just the order of decoding & the panasonic conflicted with this, as it found a match to part of the signal.
I will email you a new ini file that works and only checks for panasonic after Daikin.

Re: AC signal troubleshooting (II)
I had a look at your signal... it looks like your remote is send 2 signals for each button press as follows: 64 bits + 64 bits + 128 bits As it seems to be an official remote of daikin, I will add it in to AnalysIR as a new DAIKIN protocol. In the meantime, you can get the code for the 128 bit (seco...
