# NuttX RTOS
|
|
|
|
## What is NuttX?
|
|
|
|
[NuttX](https://nuttx.apache.org/) is a mature and secure real-time operating system (RTOS) with an emphasis on technical standards compliance and small size.
|
|
It is scalable from 8-bit to 64-bit microcontrollers and microprocessors and compliant with the Portable Operating System Interface (POSIX) and the American National Standards Institute (ANSI) standards and with many Linux-like subsystems.
|
|
The best way to think about NuttX is to think of it as a small Unix/Linux for microcontrollers.
|
|
|
|
### Highlights of NuttX
|
|
|
|
- **Small** - Fits and runs in microcontrollers as small as 32 kB Flash and 8 kB of RAM.
|
|
- **Compliant** - Strives to be as compatible as possible with POSIX and Linux.
|
|
- **Versatile** - Supports many architectures (ARM, ARM Thumb, AVR, MIPS, OpenRISC, RISC-V 32-bit and 64-bit, RX65N, x86-64, Xtensa, Z80/Z180, etc.).
|
|
- **Modular** - Its modular design allows developers to select only what really matters and use modules to include new features.
|
|
- **Popular** - NuttX is used by many companies around the world. Probably you already used a product with NuttX without knowing it was running NuttX.
|
|
- **Predictable** - NuttX is a preemptible Realtime kernel, so you can use it to create predictable applications for realtime control.

## Why NuttX + LVGL?
|
|
|
|
Although NuttX has its own graphic library called [NX](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629474), LVGL is a good alternative because users could find more eye-candy demos and they can reuse code from previous projects.
|
|
LVGL is an [Object-Oriented Component Based](https://blog.lvgl.io/2018-12-13/extend-lvgl-objects) high-level GUI library, that could fit very well for a RTOS with advanced features like NuttX.
|
|
LVGL is implemented in C and its APIs are in C.
|
|
|
|
### Here are some advantages of using LVGL in NuttX
|
|
|
|
- Develop GUI in Linux first and when it is done just compile it for NuttX. Nothing more, no wasting of time.
|
|
- Usually, GUI development for low level RTOS requires multiple iterations to get things right, where each iteration consists of **`Change code` > `Build` > `Flash` > `Run`**.
|
|
Using LVGL, Linux and NuttX you can reduce this process and just test everything on your computer and when it is done, compile it on NuttX and that is it.
|
|
|
|
### NuttX + LVGL could be used for
|
|
|
|
- GUI demos to demonstrate your board graphics capacities.
|
|
- Fast prototyping GUI for MVP (Minimum Viable Product) presentation.
|
|
- visualize sensor data directly and easily on the board without using a computer.
|
|
- Final products with a GUI without a touchscreen (i.e. 3D Printer Interface using Rotary Encoder to Input data).
|
|
- Final products with a touchscreen (and all sorts of bells and whistles).

## How to get started with NuttX and LVGL?
|
|
|
|
There are many boards in the [NuttX mainline](https://github.com/apache/incubator-nuttx) with support for LVGL.
|
|
Let's use the [STM32F429IDISCOVERY](https://www.st.com/en/evaluation-tools/32f429idiscovery.html) as an example because it is a very popular board.
|
|
|
|
### First you need to install the pre-requisites on your system
|
|
|
|
Let's use the [Windows Subsystem for Linux](https://acassis.wordpress.com/2018/01/10/how-to-build-nuttx-on-windows-10/)
|
|
|
|
```shell
|
|
$ sudo apt-get install automake bison build-essential flex gcc-arm-none-eabi gperf git libncurses5-dev libtool libusb-dev libusb-1.0.0-dev pkg-config kconfig-frontends openocd
|
|
```
|
|
|
|
### Now let's create a workspace to save our files
|
|
|
|
```shell
|
|
$ mkdir ~/nuttxspace
|
|
$ cd ~/nuttxspace
|
|
```
|
|
|
|
### Clone the NuttX and Apps repositories:
|
|
|
|
```shell
|
|
$ git clone https://github.com/apache/incubator-nuttx nuttx
|
|
$ git clone https://github.com/apache/incubator-nuttx-apps apps
|
|
```
|
|
|
|
### Configure NuttX to use the stm32f429i-disco board and the LVGL Demo
|
|
|
|
```shell
|
|
$ ./tools/configure.sh stm32f429i-disco:lvgl
|
|
$ make
|
|
```
|
|
|
|
If everything went fine you should have now the file `nuttx.bin` to flash on your board:
|
|
|
|
```shell
|
|
$ ls -l nuttx.bin
|
|
-rwxrwxr-x 1 alan alan 287144 Jun 27 09:26 nuttx.bin
|
|
```
|
|
|
|
### Flashing the firmware in the board using OpenOCD:
|
|
```shell
|
|
$ sudo openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg -c init -c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"
|
|
```
|
|
|
|
Reset the board and using the 'NSH>' terminal start the LVGL demo:
|
|
```shell
|
|
nsh> lvgldemo
|
|
```
|
|
|
|
