-E exitspec[,…]

By default, AVRDUDE leaves the parallel port in the same state at exit as it has been found at startup. This option modifies the state of the ‘/RESET’ and ‘Vcc’ lines the parallel port is left at, according to the exitspec arguments provided, as follows:

reset

The ‘/RESET’ signal will be left activated at program exit, that is it will be held low, in order to keep the MCU in reset state afterwards. Note in particular that the programming algorithm for the AT90S1200 device mandates that the ‘/RESET’ signal is active before powering up the MCU, so in case an external power supply is used for this MCU type, a previous invocation of AVRDUDE with this option specified is one of the possible ways to guarantee this condition.

noreset

The ‘/RESET’ line will be deactivated at program exit, thus allowing the MCU target program to run while the programming hardware remains connected.

vcc

This option will leave those parallel port pins active (i. e. high) that can be used to supply ‘Vcc’ power to the MCU.

novcc

This option will pull the ‘Vcc’ pins of the parallel port down at program exit.

d_high

This option will leave the 8 data pins on the parallel port active (i. e. high).

d_low

This option will leave the 8 data pins on the parallel port inactive (i. e. low).

Multiple exitspec arguments can be separated with commas.

-U memtype:op:filename[:format]

Perform a memory operation. Multiple ‘-U’ options can be specified in order to operate on multiple memories on the same command-line invocation. The memtype field specifies the memory type to operate on. Use the ‘-v’ option on the command line or the part command from terminal mode to display all the memory types supported by a particular device. Typically, a device’s memory configuration at least contains the memory types flash and eeprom. All memory types currently known are:

calibration

One or more bytes of RC oscillator calibration data.

eeprom

The EEPROM of the device.

efuse

The extended fuse byte.

flash

The flash ROM of the device.

fuse

The fuse byte in devices that have only a single fuse byte.

hfuse

The high fuse byte.

lfuse

The low fuse byte.

lock

The lock byte.

signature

The three device signature bytes (device ID).

fuseN

The fuse bytes of ATxmega devices, N is an integer number for each fuse supported by the device.

application

The application flash area of ATxmega devices.

apptable

The application table flash area of ATxmega devices.

boot

The boot flash area of ATxmega devices.

prodsig

The production signature (calibration) area of ATxmega devices.

usersig

The user signature area of ATxmega devices.

The op field specifies what operation to perform:

r

read the specified device memory and write to the specified file

w

read the specified file and write it to the specified device memory

v

read the specified device memory and the specified file and perform a verify operation

The filename field indicates the name of the file to read or write. The format field is optional and contains the format of the file to read or write. Possible values are:

i

Intel Hex

s

Motorola S-record

r

raw binary; little-endian byte order, in the case of the flash ROM data

e

ELF (Executable and Linkable Format), the final output file from the linker; currently only accepted as an input file

m

immediate mode; actual byte values specified on the command line, separated by commas or spaces in place of the filename field of the ‘-U’ option. This is useful for programming fuse bytes without having to create a single-byte file or enter terminal mode. If the number specified begins with 0x, it is treated as a hex value. If the number otherwise begins with a leading zero (0) it is treated as octal. Otherwise, the value is treated as decimal.

a

auto detect; valid for input only, and only if the input is not provided at stdin.

d

decimal; this and the following formats are only valid on output. They generate one line of output for the respective memory section, forming a comma-separated list of the values. This can be particularly useful for subsequent processing, like for fuse bit settings.

h

hexadecimal; each value will get the string 0x prepended.

o

octal; each value will get a 0 prepended unless it is less than 8 in which case it gets no prefix.

b

binary; each value will get the string 0b prepended.

The default is to use auto detection for input files, and raw binary format for output files.

Note that if filename contains a colon, the format field is no longer optional since the filename part following the colon would otherwise be misinterpreted as format.

As an abbreviation, the form -U filename is equivalent to specifying -U flash:w:filename:a. This will only work if filename does not have a colon in it.

Installing the software

If the master is not a Raspberry Pi then just install ffmpeg or avconv on your machine. 

What you need

Firstly, you need to get a few things in order for your video wall to work and to avoid messing up your network. Here is the list of required hardware:

• A Yodeck player for each screen of the video wall
• Another Yodeck player (as “Master”) that will play back the actual content
• An HDMI-to-IP video streamer – we recommend Lenkeng LKV373A (sender only, costs about $36)
• A Network router – no special specs, just having a LAN and a WAN port will do
• One Network switch to connect all of the above 

The Raspberry Pi is equipped with one SPI bus that has 2 chip selects. 

Unfortunately, there is no schematic, however wiring is pretty simple:

LCD0      - RPi

SDO(MISO) - MISO/GPIO9, pin21 (common)

LED       - 5V through 1k resistor, pin 2 (common)

SCK       - CLK/GPIO11, pin23 (common)

SDI(MOSI) - MOSI/GPIO10, pin19 (common)

D/C       - GPIO24, pin18

RESET     - GPIO25, pin22

CS        - CE0/GPIO8, pin24

GND       - GND, pin 6 (common)

VCC       - 3.3V, pin 1 (common)

LCD1      - RPi

SDO(MISO) - MISO/GPIO9, pin21 (common)

LED       - 5V through 1k resistor, pin 2 (common)

SCK       - CLK/GPIO11, pin23 (common)

SDI(MOSI) - MOSI/GPIO10, pin19 (common)

D/C       - GPIO18, pin12

RESET     - GPIO23, pin16

CS        - CE1/GPIO7, pin26

GND       - GND, pin 6 (common)

VCC       - 3.3V, pin 1 (common)
