# BlueSCSI
|

:toc: macro
|

|
||||
BlueSCSI & ArdSCSino are hardware that reproduces SCSI devices (hard disks) with an Arduino STM32F103C (aka Blue Pill.)

* Mac specific functionality
|
||||
* Passive SCSI termination
|
||||
* An alternative power source if not able to be powered by the SCSI bus

### Custom Disk Images
|
||||
|
||||
This technique is useful when you would like a disk image larger than the pre-built images in the previous section.
|
||||
|
||||
The following instructions demonstrates the process using https://ss64.com/osx/dd.html[dd] on a modern Mac:
|
||||
|
||||
1. Open terminal.
|
||||
2. The following command will create a blank disk image. You can modify the command to suit your use.
|
||||
* `dd if=/dev/zero of=example.hda bs=1m count=500`
|
||||
* The `count` field defines the number of megabytes (`bs=1m`) the total disk image should be.
|
||||
* The output file from the command is "example.hda". This can be changed in the `of=example.hda` field.
|
||||
3. Place the new blank disk image in the root directory of your SD card.
|
||||
4. If you do not already have a tool to format SCSI drives, https://macintoshgarden.org/apps/lido-756[download LIDO]. You can use an emulator such as https://www.emaculation.com/doku.php/basiliskii_osx_setup[Basilisk II] to move files to the image to prepare your installation.
|
||||
5. After booting into your target machine with the working Mac OS disk image on your BlueSCSI from step 3, format the blank disk.
|
||||
|
||||
### Termination
|
||||
|
||||
To enable termination place the two jumpers on the TERM block. Termination should be enabled if it is the last device in the chain - which is normally how it is used.
|
||||
@ -97,36 +110,20 @@ If your device is not working - check the `LOG.txt` in the root of the SD card.

### Performance is slower than expected

Try a different SD card. Cheap/old SD cards can affect performance.

## Development
|
||||
|
||||
Below is for users who wish to edit or develop on the BluePill - normal users should not need to worry about this.

### Setup PlatformIO
|

|
||||
Open the project in [PlatformIO](https://platformio.org/) and everything is pre-configured.

## Setup Arduino IDE (Depricated, Do Not Use)
|
||||
|
||||
You only need to setup the Arduino IDE if you are planning on developing and contributing to the project. Otherwise flash a provided `.bin` file.
|
||||
|
||||
1. Install `Arduino IDE` version `1.8.x` - https://www.arduino.cc/en/software
|
||||
1. Instructions may require extra steps to allow for serial/usb access depending on your OS. Read all instructions carefully.
|
||||
1. Follow these instructions _**carefully**_ as well - https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Installation
|
||||
1. **Use the 1.0.0 core** - not the master - https://github.com/rogerclarkmelbourne/Arduino_STM32/releases/tag/v1.0.0
|
||||
1. Note I used the `Arduino SAM Boards (32-bits ARM) Cortext-M3)` version `1.6.12`

1. If you get a warning about an unsigned binary - open the System Preferences -> Security -> allow stm32...
|
||||
1. Install SdFat - Tools -> Manage Libraries -> `SdFat by Bill Greiman` version `2.0.2`
|
||||
1. Make sure the correct board is selected `Generic STM32F103C series` - Copy the latest `.ino` file into a sketch and compile.
|
||||
1. Flash using your preferred method.

|
||||
1. Connect pins `SWDIO`(2), `GND`(4), `SWCLK`(6), and `3.3v`(8) from the programmer to the Blue Pill. NOTE: These are not the same as Serial ports.
|
||||
1. Using Arduino Studio Select Tools -> Upload Method -> STLink.

#### Trouble Shooting
|
||||
|
||||
If the device is not detected you may need to hold reset, click program, once it is detected release reset.
|
||||
|
||||
If you are unable to get the device in DFU mode for programming you may need to use [STM32CubeProgrammer](https://www.st.com/en/development-tools/stm32cubeprog.html) to erase the chip.
