This is mine topic. Yea, OK is 244, Source 235 and Source list 163

IrScrutinizer generate good codes but I tested badly - too fast. Now all buttons works.

I use IrScrutinizer to generate all codes from 0-255 but not found all buttons :-( e.g. OK and Source

Device addr=F (15), protocol RCA-38 (NIKAI)

This is RAW generated code for Menu button cmd=8 and works with TV:
3680, 3680, 460, 1840, 460, 1840, 460, 1840, 460, 1840, 460, 920, 460, 920, 460 ...

Yes, thx.

How IR Scope 2.01 calculate {A=$807F10EF} in IRP Form field after open ICT exported from IrScrutinizer generated NEC ADDR=01, CMD=08?

How to reverse calculate 32-bit int 807F10EF to ADDR=01, CMD=08?

Interestingly, RCExplorer does not recognize codes 04 43 send from IrDA :? :?
No, no no - that's not true. RCExplorer recognizes codes sent from Irda under one condition - the distance of the IrDa transmitter from the receiver must be approx. 2 m. The same thing I noticed when receiving the signal ...

OK, Thx.

Remote have 28-pin chip EL-2000. With such a connection of the remote control to the USB-TTL converter, after clicking the Download button in the RMIR program, the diode on the remote is blinking:

RTS - 1
TXD - 3
RXD - 4
GND - 7

Do the batteries need to be removed from the remote control when using download/upload in RMIR?

I have such voltage on the pins in my remote control:

What is the RTS line voltage? I have a universal remote control, but without user manual and without pin markings on the PCB. I want to check with the DT830 multi-meter.

I have an old MAK Maxi 2000 universal remote control. There is some 7-pin connector on the PCB. There is also an AT45DB011-SC SPI chip. I checked the pins with a meter:

OK, sorry. Here is the file: buttons.zip

Log files are in Linux format, so under Windows it is best to open them in WordPad.

I recorded more buttons and made a bash script displaying the data as it showed 3FG:
hexdump -C button.bin | awk '{
if(NR ==1) {printf "%s %s %s %s %s\n%s %s %s %s %s %s %s %s\n\n%s %s %s ", $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15, $16, $17}
if(NR ==2) {printf "%s %s %s\n%s %s ...

This is menu button 01 0a:
F3 F7 F2 F6 82
89 F5 F6 80 F3 F4 F6 85

83 F6 F0 80 F6 82
F7 F6 82 81 F6 85
83 F6 83 F5 F6 85
83 F6 83 F4 F6 85
83 F6 83 F5 F6 85
83 F6 83 F4 F6 82
F7 F6 82 81 F6 85
83 F6 83 F5 F6 85

83 F6 83 F4 F6 85
83 F6 F0 81 F6 85
83 F6 F0 80 F6 82
F7 F6 F0 82 F6 85
83 F6 F0 81 F6 ...

OK, these are three instances of the same button Addr = 01 Cmd = 08 (EPG):


P.S. I arranged it by hand
Maybe I can somehow automate in linux terminal with awk, cut ???
