@konacurrents I have the IR Remote sensor, and I can now receive IR signals.
Cannot send IR
But I cannot send any IR signals (just repeating what was received). This is the volume on 3 or my remotes. I'm using the M5Atom button (which is Button B) to make do the IRSend command.
I found the IRremote and IRSender objects. I'm also using the Port B of my I2S using pins 33 and 32.
I'm trying to send what was printed from receiving the IR:
Send with: IrSender.sendSamsung(0x7, 0x7, <numberOfRepeats>);
By calling:
IrSender.sendSamsung(0x7, 0x7, 1);
Any ideas?
My sample program is below:
/******************************************************************************

and transmitting 请连接端口B,使用红外单元接收和测试红外接收和发射.
