Most used functions

Name
Location
Summary
This function handles NMI exception.
This function handles Hard Fault exception.
This function handles Debug Monitor exception.
This function handles Memory Manage exception.
This function handles Bus Fault exception.
This function handles Usage Fault exception.
This function handles SysTick Handler.
Main program
This function handles TIM interrupt request.
Notify the User about the network interface config status
Should be called at the beginning of the program to set up the network interface. It calls the function low_level_init() to do the actual setup of the hardware. This function should be passed as a parameter to netif_add().
Custom Rx pbuf free callback
PHI IO Functions Initializes the MDIO interface GPIO and clocks.
De-Initializes the MDIO interface .
Read a PHY register through the MDIO interface.
Write a value to a PHY register through the MDIO interface.
Get the time in millisecons used for internal PHY driver process.
This function handles Ethernet interrupt request.
DHCP Process
Check the ETH link state and update netif accordingly.
Create and send a dynamic Web Page. This page contains the list of running tasks and the number of page hits.
Initialize the HTTP server (start its thread)
serve tcp connection
This task should be signaled when a receive packet is ready to be read from the interface.
Start Thread
Initializes the lwIP stack
Initializes the LCD and LEDs resources.
System Clock Configuration The system Clock is configured as follow : System Clock source = PLL (HSE) SYSCLK(Hz) = 168000000 HCLK(Hz) = 168000000 AHB Prescaler = 1 APB1 Prescaler = 4 APB2 Prescaler = 2 HSE Frequency(Hz) = 25000000 PLL_M = 25 PLL_N = 336 PLL_P = 2 PLL_Q = 7 VDD(V) = 3.3 Main regulator output voltage = Scale1 mode Flash Latency(WS) = 5
Should allocate a pbuf and transfer the bytes of the incoming packet from the interface into the pbuf.
LL Driver Interface ( LwIP stack --> ETH) In this function, the hardware should be initialized. Called from ethernetif_init().
This function should do the actual transmission of the packet. The packet is contained in the pbuf that is passed to the function. This pbuf might be chained.

Summary
Internal High Speed oscillator (HSI) value. This value is used by the RCC HAL module to compute the system frequency (when HSI is used as system clock source, directly or through the PLL). Value of the Internal oscillator in Hz
Adjust the value of External High Speed oscillator (HSE) used in your application. This value is used by the RCC HAL module to compute the system frequency (when HSE is used as system clock source, directly or through the PLL). Value of the External oscillator in Hz
Miscellaneous Configuration *********************** Vector Table base offset field. This value must be a multiple of 0x200.
