IR sender/receiver module with display and USB connector

IRMP is a port of the infrared multi-protocol decoder for Ethersex.


Connection

The reception of IR signals is performed by a receiver TSOP1736 type (or similar). This may be connected to any pin. The interrogation of the pins and the decoding of the IR protocol is done in an ISR, which occupies one 8-bit timer of the ATmegas.

When sending the signal with the carrier frequency of the respective IR Protocol is PWM modulated. This is another 8-bit timer of the ATmegas (OC0/OC2) is demonstrated. On the Etherrape board takes a NE555 this function, ie the option Use external modulator for the transmitter is activated. It saves a timer on the AVR is set at a carrier frequency.

Example of a ATMega32 from: pinning/hardware/pollin_evalboard_addon.m4

 ifdef(`conf_IRMP', `dnl
   pin(IRMP_RX, PD2)
 #define IRMP_USE_TIMER2
 #define IRMP_RX_LOW_ACTIVE
 #undef IRMP_RX_LED_LOW_ACTIVE
   pin(IRMP_TX, PD7) dnl OC2/OC2A
 #undef IRMP_TX_LED_LOW_ACTIVE
 ')

Meaning:

  • IRMP_RX - pin the IR receiver is connected to
  • IRMP_USE_TIMER2 - use Timer2 for receiver, Timer0 for sender (undef = reversed)
  • IRMP_RX_LOW_ACTIVE - the IR receiver is low-active (undef = high-active)
  • IRMP_RX_LED_LOW_ACTIVE - the control LED of the receiver is switched to USS (undef = switched to GND)
  • IRMP_TX - pin the IR sender is connected to (=output of Timer0 or Timer2, see IRMP_USE_TIMER2)
    Caution: 0A to 2A if MCU with A / B channel Without an external modulator, pins other than OC0 or 0C2 can not be used. Trying to do so will fail without an error message.
  • IRMP_TX_LED_LOW_ACTIVE - the control LED of the sender is switched to USS (undef = switched to GND)

Configuration

Each supported IR protocol occupies memory of code. Therefore, one should select only the required protocols. A detailed overview of the protocols are in article in the mikrocontroller forum.

IRMP also decodes the RC5 protocol, so that the separately Ethersex contained RC5 decoder is not needed any longer.

ECMD

IRMP implements an ECMD interface for reading received and decoded IR commands and send IR commands. See ECMD reference.

Control6

Output received characters via Syslog

CONTROL_START

THREAD(read_irmp)
ON IRMP_READ > 0 DO
  SYSLOG("IRMP %02hhd:%04hX:%04hX:%02hhX\n",
         IRMP_PROTOCOL, IRMP_ADDRESS, IRMP_COMMAND, IRMP_FLAGS);
END
THREAD_END(read_irmp)

ON STARTUP DO
  THREAD_START(read_irmp);
END

CONTROL_END

IRMP_READ checks for received IR code and stores it in the variables IRMP_PROTOCOL, IRMP_ADDRESS, and IRMP_COMMAND IRMP_FLAGS. Return values ​​greater than zero indicate the validity of the variables. If IRMP_FLAGS = 1 it is a repetition.

Control of Stella/Pins by IR commands

C6_HEADER(`/* This will be in control6.h */')
#include "services/stella/stella.h"
CONTROL_START
 
THREAD(control_stella)
ON IRMP_READ > 0 DO
  if(IRMP_PROTOCOL==8 && IRMP_ADDRESS==0x0002)
  {
    switch(IRMP_COMMAND)
    {
       case 0x0268:
          stella_setValue(STELLA_SET_IMMEDIATELY, 0, 255);
          break;

       case 0x0068:
          stella_setValue(STELLA_SET_IMMEDIATELY, 0, 0);
          break;
    }
  }
END
THREAD_END(control_stella)
 
ON STARTUP DO
  THREAD_START(control_stella);
END
 
CONTROL_END

The script switches the Stella channel 0 to 255 or 0, the remote control is a Denon (Protocol 8). With include access to the Stella sources granted.
Instead of "stella_setValue (STELLA_SET_IMMEDIATELY, 0, 255);" "PIN_SET (LED)" and "PIN_CLEAR (LED)" can be used (named pin). |Named PIN]]).
