Hi all, Yes, recently I purchased this logic analyzer. In combination with the software it is really handy. I solved some IIC problems with it.
And for Hans. I ported the sample program to a PIC16F1827 and have sent it directly to you.

It is also a portable basic oscilloscope, signal generator and component tester There are several videos on YouTube that you can search for, and it is available from Elektor, Amazon, AliExpress etc.... Hope this helps....

I think the commands you need can be found on the internet (you will nog be the first person who wants to do that). If you have the commands from the internet, then the only thing remaining is sending out the data according to the protocol, correct? I found this by Googlw: https://github.com/blafois/Daikin-IR-Reverse or https://www.instructables.com/Reverse-engineering-of-an-Air-Conditioning-control/ [https://content.instructables.com/FKG/HT5J/HRTWKE84/FKGHT5JHRTWKE84.jpg?auto=webp&frame=1&width=2100]<https://www.instructables.com/Reverse-engineering-of-an-Air-Conditioning-control/> Reverse Engineering Air Conditioner IR Remote Control Protocol<https://www.instructables.com/Reverse-engineering-of-an-Air-Conditioning-control/> Reverse Engineering Air Conditioner IR Remote Control Protocol: Hi, this is my first instructable, hope you like it.

After 4 days of struggling and a mess of results, I followed my wife's advice. I'm going to start with the old graphics approach. Make an audio recording, greatly enlarge and print it and then write down the series of zeros and ones . For example, I made my circuit earlier and last winter it switched the air conditioners on and off according to the program as heating. Remains with me the respect for the programs you all can make. regards Hans Op donderdag 31 augustus 2023 om 18:48:01 UTC+2 schreef Rob CJ: Hi Hans, What you could do is modify the NEC decoder library and change the bit times and the number of bits. Since you know which bit time is 1 and which is 0 this should be douable. The NEC prototol also starts with a pulse more or less the same as the Daikin, followed by bytes of data and a stop bit. You find the info in the library. The protocol is as follows. -- Specification of NEC IR protocol: -- Logical '0': A 562.5 us pulse burst followed by a 562.5 us space, -- with a total transmit time of 1.125 ms -- Logical '1': A 562.5 us pulse burst followed by a 1.6875ms space, -- with a total transmit time of 2.25 ms -- *) Start with 9 ms leading pulse burst (16 times the pulse burst length used -- for a logical data bit) followed by a a 4.5 ms space. -- *) 8-bit address for the receiving device or 16 bit for the extended protocol -- *) 8-bit logical inverse of the address or high byte for the extended protocol. -- *) 8-bit command. -- *) 8-bit logical inverse of the command. -- *) Final 562.5 us pulse burst to signify the end of message transmission. -- *) The four bytes of data bits are each sent least significant bit first. -- *) After a command is tranmitted and the key on the remote control is still -- pressed only a repeat message is sent consisting of a start pulse of -- 9 ms, followed by a 2.25 ms space.

I saw there is some info there but not sure if that is the info you are looking for. BTW. A tip for your program. You are declaring an array with constant values as var. You can save RAM memory by defining the array as const. You have way more const memory than var memory.

I have two daikins that are operated with infrared. After hours of puzzling, I've come to the point where I can turn them both on and off in the heating position. I would also like to know the other functions, but I dread all that work. I read the remote control with a scope and then figure out the values. Is there anyone who has already done this? Otherwise I would like to have a system to read the signals from the remote control. regards Hans -- You received this message because you are subscribed to the Google Groups "jallib" group.
