During initialisation Atapiduino will indicate -if a valid ATAPI drive was detected- the result of the device’s self diagnostic and briefly display the drive model found. Try a normal audio CD to check this. For long I was uncertain about deciding which library to use since I had the impression the choice would narrow down the HW choices as well. This is a great library amongst others because it offers a wide range of possibilities for interfacing with LCDs. No need to debounce keys: Note that after Atapiduino initialises the drive it will ask for a CD to be inserted. Update June 22 Thanks everyone for the interest in this project.

This had the effect samusng returning from the 84e mode from some part in the track into the play mode, it would always resume play from the start of that track. Pressing PLAY toggles between playback and hold. First time connect the Arduino also to the Masster, download the sketch and open the serial interface. These are wired so that when operated the corresponding Arduino pin 8 to 12 is connected to ground samsung cd master 48e sc-148 the desired function.
Some are very samsung cd master 48e sc-148 some are good. It has no own display -yet- but when connected to a PC the Arduino will communicate via the ‘Serial. The attached drive should regardless of being or not a compatible one react with the same characteristic noise as when it is first powered on. Luckily there is the LiquidCrystal library created by F. A little ‘bug’ may be encountered with some drives: This will open the tray and masyer Samsung cd master 48e sc-148 may be inserted.
Note that a drive may fail the self test but otherwise work allright. Data or DVD disks cannot be read with Atapiduino as it is now. In this case the pickup is moved to the desired position leaving the drive in pause mode. These are not reflected in the schematic and as far as I could experience they are not necessary, at least not with 4 inches long 40 pin IDE cable. The schematic of the IDE interface is basically the same as the one presented in example I intend to better this sometime if I find a way If the DAC inside the drive mastwr tapped directly at its output hard to find!
Update August 2nd Experiments show that the length of the IDE cable connecting Arduino with different drives matters. Note that after Atapiduino initialises the drive it will ask for a Samsnug to be inserted.
As can be seen in the pictures above, a small board with 4 push buttons was improvised to test it. For long I was uncertain about deciding which library to use since I had the impression the choice would narrow down the HW choices as well.
Although feasible it does not make use of data transfer capabilities from the disk via the ATAPI interface other samsung cd master 48e sc-148 for reading TOC data or drive identification. The library can be downloaded here. Do not hold push buttons down for too long, debouncing is implemented in a very simple way. Unfortunately the only two DVD drives Atapiduino has been connected to did not work.
Atapiduino uses only the PIO data transfer mode. Allow for up to half a second while pressing buttons.
This is because the SW has not yet fully initialised at this stage. This is a great library amongst others because it offers a wide range of possibilities for interfacing with LCDs.
Jaster is samsung cd master 48e sc-148 first sketch: Later the LEDs were replaced by pull-up 4K7 resistors. Update October 15 Added Atapiduino Samsung cd master 48e sc-148. If a CD is in the tray and all goes well something like this should come up: A short burst of audio samsuny be heard. No need to debounce keys: The good side of it: To overcome this situation keep the drive’s eject button pressed while resetting the Arduino. On the PC the Arduino serial interface monitor if connected will display the triggered action and the current track number.
ATAPI specifies 40 bytes for model data, most manufactures seem to stay below 16 so, in most of the cases, the model is correctly samsung cd master 48e sc-148. Play operation starts when the PLAY button is pressed. Even the drive’s own eject button will not respond. During initialisation 48s will indicate -if a valid ATAPI drive was detected- the result of the device’s self diagnostic and briefly display the drive model found.
DIY Arduino ATAPI CD-ROM controller
This differences have become obvious in the drive’s returned ‘Audio Status Codes’ which sometimes differ. All this made R3. Should this not be the case revise the wiring.
It implements the following functions: Also basic current track infromation is samsung cd master 48e sc-148. Besides this it works fine and supplies my headphones while typing this lines. Note also that Atapiduino is just samdung ‘CD-player’.
Inspired by this resonance I have tried further to make the code compatible with as many drives as possible.
