RTOS/MSP-EXP432E401Y: HTTP Server with MSP432

Tool/software: TI-RTOS

I cannot comment to the original thread regarding the MSP432E401Y and HTTP server support.

But maybe this can help someone

Http server support is already included in the ti/ndk/nettools/lib/nettool_ipv4.aem4f library.

In the latest SimpleLink MSP432e4 SDK see this document

/ti/simplelink_msp432e4_sdk_2_10_00_17/docs/ndk/NDK_API_Reference.html#e-web-programming-with-the-http-server

The solution is very simple.

Add this to the one of the TCP examples in tirtos/ndk_tirtos.c

static void initIHttp(void *hCfg)
{
     CI_SERVICE_HTTP http;

	bzero( &http, sizeof(http) );
	http.cisargs.IPAddr = INADDR_ANY;
	http.cisargs.pCbSrv = &ServiceReport;
	CfgAddEntry( hCfg, CFGTAG_SERVICE, CFGITEM_SERVICE_HTTP, 0,
                     sizeof(http), (UINT8 *)&http, 0 );
}

And change in ndkStackThread

/* IP, TCP, and UDP config */
initIp(hCfg);
initTcp(hCfg);
initUdp(hCfg);
initHttp(hCfg);

Also add your web files as in the Tiva examples:

Void AddWebFiles(Void)
{
    //Note: both INDEX_SIZE and INDEX are defined in index.h
    efs_createfile("index.html", INDEX_SIZE, (UINT8 *)INDEX);
    efs_createfile("greetings.html", GREETINGS_SIZE, (UINT8 *)GREETINGS);
    efs_createfile("chip.jpg", CHIP_SIZE, (UINT8 *)CHIP);
}

Void RemoveWebFiles(Void)
{
    efs_destroyfile("index.html");
    efs_destroyfile("greetings.html");
    efs_destroyfile("chip.jpg");
}

You obviously have to use the binsrc tool found in simplelink_msp432e4_sdk_2_10_00_17\source\ti\ndk\tools\binsrc\ to compile the web files to binary arrays.

I had to increase the raw page count in tirtos/ndk_tirtos.c from 6 to 12 to have enough memory to serve the web pages.

AddWebFiles/RemoveWebFiles can be called statically

or configure xctools like so

/* ================ Application Specific Instances ================ */
var Global = xdc.useModule('ti.ndk.config.Global');
var Http = xdc.useModule('ti.ndk.config.Http');
Global.IPv6 = false;
var http0Params = new Http.Params();
var http0 = Http.create(http0Params);
Global.stackInitHook = "&AddWebFiles";
Global.stackDeleteHook = "&RemoveWebFiles";

I used the static option tirtos/ndk_tirtos.c just before configuring the http server.

Hope it is helpful to someone.

If anyone is interested I can maybe edit one of the example with full http server support and load on github
