Hi
I will setup an application on my STM32H743ZI2 which should make a Client socket connection using the LwIP and netconn. When i'm uisng the LwIP HTTP Server Netconn RTOS example i can make it work and the Netonn API functions is working,
If i instead of uising the example is starting a project using CubeMX and Enabling the LwIP, activating the FREETOS, enabling the CPU iCache and DCache.
In the LwIP settings i activate the LWIP_NETCONN (NETCONN API) and checking that the follwing, described, is set correctly
LWIP_NETCONN (NETCONN API)
Diagnostic:
Dependency: Use NETCONN API requires NO_SYS=0 and MEMP_NUM_TCPIP_MSG_API>0 if MEMP_MEM_MALLOC is disabled.
Parameter Description:
When this parameter is enabled, Netconn API is enabled (require to use api_lib.c).
I'm then generating the project to run in Keil and in the main. c i #include the api.h, in lwipopts.h i define the LWIP_NETCONN. Within the thread in just using the same setup as in the working example, see some of this below.
struct netconn *conn;
err_t err, accept_err;
ip_addr_t ipaddr;
u16_t socketPort = 18761;
IP4_SET_ADDR(ipaddr, 192, 168, 0, 101);
/* Create tcp_ip stack thread */
tcpip_init(NULL, NULL);
/* Initialize the LwIP stack */
Netif_Config(); // Function just copied from the example.
if (conn != NULL)
{
while (netconn_connect(conn, &ipaddr, socketPort) != ERR_OK) {
...
}
When compiling this i get a lot of error saying that a lot of the Netconn part is undefined. What am i doing wrong or what am I missing to include or activate.
