Import serial ser = serial.Serial ('/dev/ttyAMA0') ser.baudrate = 2400 for i in range (0,15): # usually IR signal for a key is about 12-16 bytes data = ser.read(1) # read 1 byte at a time print ord(data) # the data read in character, ord will convert to ASCII value Now this code will read IR signal 1 byte at a time and prints out the value. The Python code to read the IR signal found out to be very very simple. Then output signal of IR sensor connected to GPIO 15.
Since my aim is to receive the IR signals I wired only GPIO 15 (RX).

Sudo apt-get install python-serial Once this is installed Python code can use it by doing import serial. To get the serial (UART) communication working need to install the Serial module.

Update the inittab file to mask the ttyAMA0 sudo nano /etc/inittab Comment out the line ‘X:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100′ #X:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100 Then save and close the editor. Sudo nano /boot/cmdline.txt The remaining file looks like, dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p6 rootfstype=ext4 elevator=deadline rootwait Then save and close the editor. Edit the file cmdline.txt by removing the parameters containing ‘ttyAMA0‘.First make a backup of the file containing kernel parameters cmdline.txt as cmdline_bp.txt sudo cp /boot/cmdline.txt /boot/cmdline_bp.txt.Need to remove ttyAMA0 entries in cmdline.txt. Preparing Raspberry Pi for UART serial communication. This is a crude but a simple way of reading IR remote for simple applications that can be used in Raspberry Pi. What I did was to read the data value coming out of IR sensor serially. The IR sensor decodes the IR waves and passes the data serially. After some reading about how IR remote communicate the info revealed that uses UART serial communication. I gave up and then I try to write a python code to capture IR remote without using LIRC. When I wanted pass the IR remote Key value to Python program it doesn't pass it correctly. To be able to know which IR codes to send must I first record the IR codes from my TV's remote and after that can I play the recorded IR codes, thus controlling the TV. Serial port IR transmitter/receiver The idea is that I want to be able to control my TV from my PC and to be able to do that must I send IR codes to the TV. The receiver is connected at serial port 1 (/dev/ttyS0) on this hardware (successfully testet with VDR software which was on exactly this hardware before). Hi I want to use my cheap Lirc receiver on my XBMC-Hardware (ScenicE620). Everything was ok, except the very last step. I manged to get LIRC installed and tested. I wanted get an IR remote input to Raspberry Pi. Honor a courageous man in the police force or armed forces Durable badge shaped pewter medal with chain St.
