STM32CubeMX lwip should generate USER section to allow customization of IP Address per device
STM32CubeMX lwip should generate USER section to allow customization of IP Address per device
currently I use CubeMX 5.6 and STM32F4 1.25
The IP address is specified in the ioc file. But when I have many boards it is not suitable to generate 1 project per board ...
For the MAC address there is such proposed solution in the file ethernetif.c implemented.
currently in the autogenerated lwip.c file the code lookes like this:
void MX_LWIP_Init(void)
{
/* IP addresses initialization */
IP_ADDRESS[0] = 192;
IP_ADDRESS[1] = 168;
IP_ADDRESS[2] = 123;
IP_ADDRESS[3] = 3;
NETMASK_ADDRESS[0] = 255;
NETMASK_ADDRESS[1] = 255;
NETMASK_ADDRESS[2] = 255;
NETMASK_ADDRESS[3] = 0;
GATEWAY_ADDRESS[0] = 0;
GATEWAY_ADDRESS[1] = 0;
GATEWAY_ADDRESS[2] = 0;
GATEWAY_ADDRESS[3] = 0;
/* Initilialize the LwIP stack without RTOS */
lwip_init();
/* IP addresses initialization without DHCP (IPv4) */
IP4_ADDR(&ipaddr, IP_ADDRESS[0], IP_ADDRESS[1], IP_ADDRESS[2], IP_ADDRESS[3]);
IP4_ADDR(&netmask, NETMASK_ADDRESS[0], NETMASK_ADDRESS[1] , NETMASK_ADDRESS[2], NETMASK_ADDRESS[3]);
IP4_ADDR(&gw, GATEWAY_ADDRESS[0], GATEWAY_ADDRESS[1], GATEWAY_ADDRESS[2], GATEWAY_ADDRESS[3]);
/* add the network interface (IPv4/IPv6) without RTOS */
netif_add(&gnetif, &ipaddr, &netmask, &gw, NULL, ðernetif_init, ðernet_input);
/* Registers the default network interface */
netif_set_default(&gnetif);So for the instance there should be a possible USER SECTION after variable assignment and any function call.
like this:
void MX_LWIP_Init(void)
{
/* IP addresses initialization */
IP_ADDRESS[0] = 192;
IP_ADDRESS[1] = 168;
IP_ADDRESS[2] = 123;
IP_ADDRESS[3] = 3;
NETMASK_ADDRESS[0] = 255;
NETMASK_ADDRESS[1] = 255;
NETMASK_ADDRESS[2] = 255;
NETMASK_ADDRESS[3] = 0;
GATEWAY_ADDRESS[0] = 0;
GATEWAY_ADDRESS[1] = 0;
GATEWAY_ADDRESS[2] = 0;
GATEWAY_ADDRESS[3] = 0;
/* USER CODE END IPADDRESS /
/ USER CODE END IPADDRESS */
/* Initilialize the LwIP stack without RTOS */
lwip_init();
...Currently I have to patch after every project generation. Again and again.
Thanks ST for providing those changes in next release.
Adib.
