## iMXRT1062 Driver
|
|
|
|
A grblHAL driver for the NXP iMXRT1062 processor on a [Teensy 4.x board](https://www.pjrc.com/store/teensy40.html).
|
|
|
|
This driver compiles and uploads from the Arduino IDE and is partially dependent on the Arduino framework. [Teensyduino](https://www.pjrc.com/teensy/td_download.html) is required and must be added to the Arduino IDE.
|
|
|
|
See the Wiki-page for [compiling grblHAL](https://github.com/grblHAL/core/wiki/Compiling-GrblHAL) for instructions for how to import the project, configure the driver and compile.
|
|
|
|
Available driver options can be found [here](main/my_machine.h).

#### Networking plugin
|
|
|
|
The networking plugin is for Teensy 4.1 and needs the [teensy41_ethernet lwIP library](https://github.com/ddrown/teensy41_ethernet) forked by ddrown.
|
|
|
|
Telnet and websocket protocols are currently supported, http is on the long term roadmap.
|
|
|
|
#### SD card plugin
|
|
|
|
The SD card plugin needs the [uSDFS library](https://github.com/WMXZ-EU/uSDFS) by WMXZ-EU.
|
|
|
|
Important: edit the [utility/sd_config.h](https://github.com/WMXZ-EU/uSDFS/blob/master/src/utility/sd_config.h) file and change
|
|
|
|
`#define USE_MSC 1 // will be used in sd_msc.cpp`
|
|
|
|
to
|
|
|
|
`#define USE_MSC 0 // will be used in sd_msc.cpp`
|
|
|
|
or add the MSC library as well \(not needed\).

|
<sup>1</sup> Each enabled reduces N_AXIS with one. Currently the board map file must be edited to enable ganged/auto squared axes.
|
|
<sup>2</sup> I<sup>2</sup>C EEPROM \(or FRAM\) is [optional](https://github.com/grblHAL/Plugin_EEPROM/blob/master/README.md) and must be added to the board. FRAM is recommended when the [Odometer plugin](https://github.com/grblHAL/Plugin_odometer/blob/master/README.md) is added to the build.
|
|
<sup>3</sup> Number of digital input pins available is reduced when the [Encoder plugin](https://github.com/grblHAL/Plugin_encoder/blob/master/README.md) is added to the build.
