Here is a MMBasic version of the NECsend Subroutine that supports 8 and 16 bit Device Codes,
with or without bit order reversal*** and the Samsung32 variant.
Tested on Picomite and ArmMiteF4.

***The MMBasic IR reading command outputs codes with MSB first and 16 bit Device Code so this is the default setting
but the NEC specifies LSB first. This can be selected with an extra parameter if you have codes intended for that format.

Usage:
Call "NECsend DeviceCode, KeyCode [, Variant]"

If using the Sub in an existing program that can't have a separate Variant parameter the parameter can instead be bit shifted up 16 and added to the DeviceCode.

eg Inc DeviceCode, (Variant << 16)
Then Call "NECsend DeviceCode, KeyCode

Variant:
0 standard NEC 16 bit DeviceCode, MSB first (default)
1 Samsung32
2 standard NEC 8 bit DeviceCode, MSB first
3 standard NEC 16 bit DeviceCode, LSB first
4 standard NEC 8 bit DeviceCode, LSB first

' "NECsend with option for Samsung32 variant.bas"
'Dim Integer IRpin=MM.Info(pinno GP0) 'for Picomite - set your output pin
Dim Integer IRpin=MM.Info(pinno PA0) 'for ArmMiteF4 - set your output pin
Dim Integer dev, key, V 'for standard NEC V = 0, or omit. V = 1 for Samsung32
'for 8 bit NEC Dev code V = 2
'for 16 bit, LSB first NEC Dev code V = 3
'for 8 bit, LSB first NEC Dev code V = 4

'Alternatively those variants can instead be denoted by adding them to Dev above bit 16

'Stop Bit 550uS pulse (almost same as NEC - 562.5uS)
'Repetition after 47mS
End

The current F4 BitBang Bitstream command has a small timing error, however for most devices it is close enough.
If some don't work changing: Math set 13, d() to Math set 14, d() should fix it.

The MMBasic IR command reads Sony and standard NEC codes but not the Samsung32 variant.
So here is a IR code reader for the Samsung32 variant. Tested on a PicoMite.
Samsung32 has a 4.5mS start pulse instead of 9mS and has an 8 bit device code repeated without inverting.
Bit timings are multiples of 550uS instead of 562.5uS but I found 560uS works for both.

First Bug - MM.INFO(Pinno xx) is different on F4 to Pico. It gives the first pin of the Port, not the individual pin number.
By blind luck the pin I used was the first pin of that port so it worked.

For the F4 define IRpin this way:-
' "NECsend with option for Samsung32 variant.bas"
'Dim Integer IRpin = MM.Info(pinno GP0) 'for Picomite - set your output pin
Dim Integer IRpin = 23 '= PA0 for ArmMiteF4 - set your output pin

Thanks Geoff and Marcel, after any problems or improvements have been sorted out I will post it on FOTS.

If anyone has other variants of the NEC protocol post them here and I will try to add them to the Sub.

As I have only one Samsung device to test on I would like to know if these programs work on others.

First Bug - MM.INFO(Pinno xx) is different on F4 to Pico. It gives the first pin of the Port, not the individual pin number.
By blind luck the pin I used was the first pin of that port so it worked.

For the F4 define IRpin this way:-

' "NECsend with option for Samsung32 variant.bas"
'Dim Integer IRpin = MM.Info(pinno GP0) 'for Picomite - set your output pin
Dim Integer IRpin = 23 '= PA0 for ArmMiteF4 - set your output pin

The Samsung receiver program has now been tested on the ArmMiteF4 using this setup:-

An update for the IR Receiver program above.
It now also does standard NEC codes with 8 and 16 bit Device codes using NECs LSB first format.
It saves the results to a file, including the variant number in a format that can be copied and pasted into the NECsend program.

Edit 3 9/9/2024
The code above has been edited again, adding the JVC 16 bit protocol. Close enough to NEC to count as Variant 5.

The received codes match the corresponding functions at the end of this document:-
JVC Protocol so I know it is working.
The main difference is it uses only 16 bits so there is no inherent error detection. The remote always sends the code at least twice so it would be possible to modify my code to read both copies and compare them.

Another difference is the remote control can have more than one Device Code to cater for multi function devices.

Edit
Edited the code above to send the JVC 16 bits twice.
I think some JVC devices may require it.

Hi Phil,

I think it is great what you are doing, but I do not have a real application for it, nor do I have compatible devices. My Philips TV is the only device I really use an RC with. The Sony DVD/Blueray player is never used anymore. Neither is the Harman Kardon radio since they removed all FM broacast from cable. And for 1 year (2026 is last year FM broadcast in the air in Netherlands) I am not putting up an antenna mast anymore.

Sorry, I can't use your RX and TX programs. But I do follow the series, if that is any comfort...

Thanks, I plan to do the Philips protocol eventually but it is incompatible with any version the NEC Pulse-interval modulation. It uses bi-phase modulation and Manchester encoding.

Philips RC-5 protocol is now done.

Also RC-6 in the RC-5 thread.

I can appreciate this code. I repair amplifiers and not every amp has an original remote unit anymore. If you want to setup these 5.1 or 7.1 devices you need a remote unit for the setup menu most of the time because certain menu options can't be accessed by front buttons. If I have an universal transmitter and when I know the codes I can access these menu's. A non-original remote cost me most of the times €19,95, therefore I welcome the effort of phil99.

If you use AI, you lose your mind.
