The `mongoose.c` and `mongoose.h` files are, actually, an amalgamation -
a non-amalgamated sources can be found at https://github.com/cesanta/mongoose/tree/master/src
Mongoose source code uses a bunch of build constants defined at
https://github.com/cesanta/mongoose/blob/master/src/config.h, together with
their default values.
In order to change the constant during build time, use the `-D
<PREPROCESSOR_FLAG>` compiler option. For example, to disable both MQTT,
compile the application `my_app.c` like this (assumed UNIX system):
Mongoose have two types of build constants (preprocessor definitions) that
affect the build: a target architecture, and tunables. In order to set the
option during build time, use the `-D OPTION` compiler flag:
```sh
$ cc my_app.c mongoose.c -D MG_MQTT_ENABLE=0
$ cc app0.c mongoose.c # Use defaults!
$ cc app1.c mongoose.c -D MG_ENABLE_IPV6=1 # Build with IPv6 enabled
$ cc app2.c mongoose.c -D MG_ARCH=MG_ARCH_UNIX # Set UNIX architecture
$ cc app3.c mongoose.c -D MG_ENABLE_FS=0 -D MG_ENABLE_LOG=0 # Multiple options
```
The list of supported
architectures is defined in the
[arch.h](https://github.com/cesanta/mongoose/blob/master/src/arch.h) header
file. Normally, there is no need to explicitly specify the architecture. The
architecture is guessed during the build, so setting it is not usually required.
| Name | Description |
| ---- | ----------- |
|MG_ARCH_UNIX | All UNIX-like systems like Linux, MacOS, FreeBSD, etc |
|MG_ARCH_WIN32 | Windows systems |
|MG_ARCH_ESP32 | Espressif's ESP32 |
|MG_ARCH_ESP8266 | Espressif's ESP8266 |
|MG_ARCH_FREERTOS_TCP | All systems with FreeRTOS kernel and FreeRTOS-Plus-TCP IP stack |
|MG_ARCH_CUSTOM | A custom architecture, discussed in the next section |
The other class of build constants is defined in
[src/config.h](https://github.com/cesanta/mongoose/blob/master/src/config.h)
together with their default values. They are tunables that include/exclude
a certain functionality or change relevant parameters.
Here is a list of build constants and their default values:
| Name | Default | Description |
| ---- | ------- | ----------- |
|`MG_ENABLE_SOCKET` | 1 | Use BSD socket low-level API |
|`MG_ENABLE_MBEDTLS` | 0 | Enable Mbed TLS library |
|`MG_ENABLE_OPENSSL` | 0 | Enable OpenSSL library |
|`MG_ENABLE_FS` | 1 | Enable API that use filesystem, like `mg_http_send_file()` |

## Custom build
The list of supported architectures is defined in the
[arch.h](https://github.com/cesanta/mongoose/blob/master/src/arch.h) header
file. Normally, there is no need to explicitly specify the architecture.
The architecture is guessed during the build, so a simple compilation like
`cc main.c mongoose.c` should work fine in most cases.
However if you're building on embedded system like STM32, NXP, Xilinx or other,
an architecture should be specified explicitly:
- `-DMG_ARCH=MG_ARCH_FREERTOS_TCP` - for environments with FreeRTOS and
FreeRTOS-TCP stack
- `-DMG_ARCH=MG_ARCH_CUSTOM` for all other cases, for example on systems with
FreeRTOS+LWIP, or bare metal + custom IP stack
Below is the guide for building with `MG_ARCH_CUSTOM` architecture:
A custom build should be used for cases which is not covered by the
existing architecture options. For example, an embedded architecture that
uses some proprietary RTOS and network stack. In order to build on such
systems, follow the guideline outlined below:
1. Add `-DMG_ARCH=MG_ARCH_CUSTOM` to your build flags.

##### Initialization and Configuration functions #####
===============================================================================
[..] This section provides functions allowing to:
(+) Initializes the Flash interface the NVIC allocation and initial clock
configuration. It initializes the systick also when timeout is needed
and the backup domain when enabled.
(+) De-Initializes common part of the HAL.
(+) Configure the time base source to have 1ms time base with a dedicated
Tick interrupt priority.
(++) SysTick timer is used by default as source of time base, but user
can eventually implement his proper time base source (a general purpose
timer for example or other time source), keeping in mind that Time base
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
handled in milliseconds basis.
(++) Time base configuration function (HAL_InitTick ()) is called automatically
at the beginning of the program after reset by HAL_Init() or at any time
when clock is configured, by HAL_RCC_ClockConfig().
(++) Source of time base is configured to generate interrupts at regular
time intervals. Care must be taken if HAL_Delay() is called from a
peripheral ISR process, the Tick interrupt line must have higher priority
(numerically lower) than the peripheral interrupt. Otherwise the caller
ISR process will be blocked.
(++) functions affecting time base configurations are declared as __weak
to make override possible in case of other implementations in user file.

* @author MCD Application Team
* @brief CORTEX HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the CORTEX:
* + Initialization and de-initialization functions
* + Peripheral Control functions
*
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
*** How to configure Interrupts using CORTEX HAL driver ***
===========================================================
[..]
This section provides functions allowing to configure the NVIC interrupts (IRQ).
The Cortex-M4 exceptions are managed by CMSIS functions.
(#) Configure the NVIC Priority Grouping using HAL_NVIC_SetPriorityGrouping()
function according to the following table.
(#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority().
(#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ().
(#) please refer to programming manual for details in how to configure priority.
-@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible.
The pending IRQ priority will be managed only by the sub priority.
-@- IRQ priority order (sorted by highest to lowest priority):
(+@) Lowest preemption priority
(+@) Lowest sub priority
(+@) Lowest hardware priority (IRQ number)
[..]
*** How to configure Systick using CORTEX HAL driver ***
========================================================
[..]
Setup SysTick Timer for time base.
(+) The HAL_SYSTICK_Config() function calls the SysTick_Config() function which
is a CMSIS function that:
(++) Configures the SysTick Reload register with value passed as function parameter.
(++) Configures the SysTick IRQ priority to the lowest value (0x0F).
(++) Resets the SysTick Counter register.
(++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
(++) Enables the SysTick Interrupt.
(++) Starts the SysTick Counter.
(+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
__HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
inside the stm32f7xx_hal_cortex.h file.
(+) You can change the SysTick IRQ priority by calling the
HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function
call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
(+) To adjust the SysTick time base, use the following formula:
Reload Value = SysTick Counter Clock (Hz) x Desired Time base (s)
(++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
(++) Reload Value should not exceed 0xFFFFFF

* @brief GPIO HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the General Purpose Input/Output (GPIO) peripheral:
* + Initialization and de-initialization functions
* + IO operation functions
*
@verbatim
==============================================================================
##### GPIO Peripheral features #####
==============================================================================
[..]
Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each
port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software
in several modes:
(+) Input mode
(+) Analog mode
(+) Output mode
(+) Alternate function mode
(+) External interrupt/event lines
[..]
During and just after reset, the alternate functions and external interrupt
lines are not active and the I/O ports are configured in input floating mode.
[..]
All GPIO pins have weak internal pull-up and pull-down resistors, which can be
activated or not.
[..]
In Output or Alternate mode, each IO can be configured on open-drain or push-pull
type and the IO speed can be selected depending on the VDD value.
[..]
All ports have external interrupt/event capability. To use external interrupt
lines, the port must be configured in input mode. All available GPIO pins are
connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
[..]
The external interrupt/event controller consists of up to 23 edge detectors
(16 lines are connected to GPIO) for generating event/interrupt requests (each
input line can be independently configured to select the type (interrupt or event)
and the corresponding trigger event (rising or falling or both). Each line can
also be masked independently.
##### How to use this driver #####
==============================================================================
[..]
(#) Enable the GPIO AHB clock using the following function: __HAL_RCC_GPIOx_CLK_ENABLE().
(#) Configure the GPIO pin(s) using HAL_GPIO_Init().
(++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
(++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
structure.
(++) In case of Output or alternate function mode selection: the speed is
configured through "Speed" member from GPIO_InitTypeDef structure.
(++) In alternate mode is selection, the alternate function connected to the IO
is configured through "Alternate" member from GPIO_InitTypeDef structure.
(++) Analog mode is required when a pin is to be used as ADC channel
or DAC output.
(++) In case of external interrupt/event selection the "Mode" member from
GPIO_InitTypeDef structure select the type (interrupt or event) and
the corresponding trigger event (rising or falling or both).
(#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
HAL_NVIC_EnableIRQ().
(#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
(#) To set/reset the level of a pin configured in output mode use
HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
(#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
(#) During and just after reset, the alternate functions are not
active and the GPIO pins are configured in input floating mode (except JTAG
pins).
(#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
(PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
priority over the GPIO function.
(#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
The HSE has priority over the GPIO function.
