Additional documentation can be found at the [Marlin Home Page](https://marlinfw.org/).
Please test this firmware and let us know if it misbehaves in any way. Volunteers are standing by!
## Marlin 2.0
Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
Download earlier versions of Marlin on the [Releases page](https://github.com/MarlinFirmware/Marlin/releases).
## Example Configurations
Before building Marlin you'll need to configure it for your specific hardware. Your vendor should have already provided source code with configurations for the installed firmware, but if you ever decide to upgrade you'll need updated configuration files. Marlin users have contributed dozens of tested example configurations to get you started. Visit the [MarlinFirmware/Configurations](https://github.com/MarlinFirmware/Configurations) repository to find the right configuration for your hardware.
## Building Marlin 2.0
To build Marlin 2.0 you'll need [Arduino IDE 1.8.8 or newer](https://www.arduino.cc/en/main/software) or [PlatformIO](http://docs.platformio.org/en/latest/ide.html#platformio-ide). Detailed build and install instructions are posted at:
- [Installing Marlin (Arduino)](http://marlinfw.org/docs/basics/install_arduino.html)
- [Installing Marlin (VSCode)](http://marlinfw.org/docs/basics/install_platformio_vscode.html).

## License
Marlin is published under the [GPL license](/LICENSE) because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
1. Install Anet board definition for Arduino IDE from `./anet-board` ([Source](https://github.com/SkyNet3D/anet-board))

# Introduction
This project provides a board definition which enables the Arduino IDE to compile firmware (such as Marlin) for Anet 3D printers. It is used in the SkyNet3D Marlin distribution for Anet printers, but can be used independently to, for example, build Marlin from source.
## Installation Instructions
Copy the included 'anet' folder into the 'hardware' folder of your Arduino installation.
1. Download the most recent version from the 1.8.x branch of the Arduino IDE from
https://www.arduino.cc/en/main/software
2. Download a zip file of the master branch of this project using the 'Clone or Download' button
3. Install the Arduino IDE using the default options
Then:
#### Windows
4. Open your `Documents` folder in Windows Explorer
5. Open the `Arduino` folder, then the `hardware` sub-folder. If neither of these folders exist, create them.
6. Open the anet-board zip file you downloaded in step 2 and copy the 'anet' folder into `Documents\Arduino\hardware`
#### OS X
4. Click on "Documents" in Finder and look for the `Arduino` directory inside it. The full path is `~/Documents/Arduino/hardware`
5. Open the anet-board zip file you downloaded in step 2 and copy the 'anet' folder into `~/Documents/Arduino/hardware`
## Using the Board Definition
1. Open the Arduino IDE
2. Open the Tools->Board menu and select either of the Anet V1.0 boards
3. Open the Tools->Port menu and select the appropiate COM port (the one which appeared when you plugged your printer into a USB port)
**Note:** The Optiboot board option is highly recommended as the Optiboot bootloader uses much less space than the standard Atmega 1284p bootloader, allowing more flash space for the firmware. If you choose to use the Optiboot option you **MUST** burn the Optiboot bootloader before uploading firmware, otherwise you risk overwriting the bootloader.
When uploading firmware, use Sketch->Upload (Ctrl+U), which uploads over the USB connection, **not** Sketch->Upload Using Programmer (unless you're actually using an Arduino programmer and know what you're doing).
## Burning the Bootloader
Burning the bootloader to the board requires either an Arduino programmed as an ISP, or a USBasp. The programmer is connected to the middle six pins of the J3 connector on the Anet v1.0 board.
Burning the bootloader to an Arduino always erases the flash memory. Once the bootloader has been burned using a programmer the programmer should be disconnected and firmware uploaded using the serial-over-USB connection.
With the programmer connected:
1. Launch the Arduino IDE
2. Select the appropriate board from the Tools->Boards menu - either `Anet V1.0` or `Anet V1.0 (Optiboot)`
3. Click Tools -> Burn Bootloader
4. The board will reset when complete, and the LCD display will be blank
Assuming there were no errors, at this point the firmware has been erased and will need to be re-uploaded. The programmer should be disconnected.

/** \defgroup avr_boot <avr/boot.h>: Bootloader Support Utilities
\code
#include <avr/io.h>
#include <avr/boot.h>
\endcode
The macros in this module provide a C language interface to the
bootloader support functionality of certain AVR processors. These
macros are designed to work with all sizes of flash memory.
Global interrupts are not automatically disabled for these macros. It
is left up to the programmer to do this. See the code example below.
Also see the processor datasheet for caveats on having global interrupts
enabled during writing of the Flash.
\note Not all AVR processors provide bootloader support. See your
processor datasheet to see if it provides bootloader support.
\todo From email with Marek: On smaller devices (all except ATmega64/128),
__SPM_REG is in the I/O space, accessible with the shorter "in" and "out"
instructions - since the boot loader has a limited size, this could be an
important optimization.
\par API Usage Example
The following code shows typical usage of the boot API.
\code
#include <inttypes.h>
#include <avr/interrupt.h>
#include <avr/pgmspace.h>
void boot_program_page (uint32_t page, uint8_t *buf)
{
uint16_t i;
uint8_t sreg;
// Disable interrupts.
sreg = SREG;
cli();
eeprom_busy_wait ();
boot_page_erase (page);
boot_spm_busy_wait (); // Wait until the memory is erased.
for (i=0; i<SPM_PAGESIZE; i+=2)
{
// Set up little-endian word.
uint16_t w = *buf++;
w += (*buf++) << 8;
boot_page_fill (page + i, w);
}
boot_page_write (page); // Store buffer in flash page.
boot_spm_busy_wait(); // Wait until the memory is written.
// Reenable RWW-section again. We need this if we want to jump back
// to the application after bootloading.
boot_rww_enable ();
// Re-enable interrupts (if they were ever enabled).
SREG = sreg;

Bits by SPM To set the Boot Loader Lock bits, write the desired data to

that may prevent the Application and Boot Loader section from any
software update by the MCU.
If bits 5..2 in R0 are cleared (zero), the corresponding Boot Lock bit
will be programmed if an SPM instruction is executed within four cycles
after BLBSET and SPMEN (or SELFPRGEN) are set in SPMCR. The Z-pointer is
don't care during this operation, but for future compatibility it is
recommended to load the Z-pointer with $0001 (same as used for reading the

6, 1, and 0 in R0 to 1 when writing the Lock bits. When programming the

* NRWW memory
* Addresses below NRWW (Non-Read-While-Write) can be programmed while
* continuing to run code from flash, slightly speeding up programming
* time. Beware that Atmel data sheets specify this as a WORD address,
* while optiboot will be comparing against a 16-bit byte address. This
* means that on a part with 128kB of memory, the upper part of the lower
* 64k will get NRWW processing as well, even though it doesn't need it.
* That's OK. In fact, you can disable the overlapping processing for
* a part entirely by setting NRWWSTART to zero. This reduces code
* space a bit, at the expense of being slightly slower, overall.
*
* RAMSTART should be self-explanatory. It's bigger on parts with a
* lot of peripheral registers.
