If you wanted to pass another argument through to your device and have it process them both (such as one argument for the page and the other argument for the device ID), you could make another version of this function to process the other argument: int8_t analyse_cmd (char *str) { int8_t r = -1; if (find_key_val (str,"cmd")) { if (*strbuf < 0x3a && *strbuf > 0x2f) { // is a ASCII number, return it r = (*strbuf-0x30); } } return r; } The function to print the web page with the sensor data is long, but that s only because it s very repetitive; the structure of the function is quite simple.

Before any HTML purists look at what is being returned and start complaining about things such as lack of a doctype declaration or even basic things such as HTML body tags, we should point out that the page defined in this function is designed to be absolutely minimal in size rather than technically correct The reality is that in 500 or so bytes it s simply not possible to return a fully formed HTML page including all the headers and the content required, so we ve taken more than a few shortcuts that would have us on trial for crimes against RFCs if we tried to pass this off as a valid web page It gets the job done, though, which is what matters.

Note The COR_E* exceptions were defined when .NET was first introduced and are defined in CorError.h.

The major reason for setting up clients and departments is to use them for access control. FogBugz allows you to set up permissions (access control) so that only certain users can see or modify certain cases. Before you can start assigning permissions, you need to create at least one client or department. Typically, you will use FogBugz access control for one of two purposes: Hiding clients from each other Limiting users to their own department

The function first defines a set of arrays to hold the values returned by each sensor, as well as variables for a counter (to be used a little later in the function) and for the packet length If you want to expand this project to support more sensors you would need to define more arrays to suit uint16_t print_webpage (uint8_t *buf) { // Arrays to hold the temperature reading from each sensor char temp_string_a[10]; char temp_string_b[10]; char temp_string_c[10]; char temp_string_d[10]; char temp_string_e[10]; char temp_string_f[10]; int i; // Counter used while iterating over reading arrays uint16_t plen; // Length of response packet It then reads all the temperature sensors This can safely be done even if you don t have six sensors connected because it will simply return 00 degrees for any unconnected channels // Read all the temperature sensors getCurrentTemp(SENSOR_A, temp_string_a);.

They are designed to provide a much larger set of HRESULT codes that are mapped to specific .NET exceptions.

getCurrentTemp(SENSOR_B, temp_string_b); getCurrentTemp(SENSOR_C, temp_string_c); getCurrentTemp(SENSOR_D, temp_string_d); getCurrentTemp(SENSOR_E, temp_string_e); getCurrentTemp(SENSOR_F, temp_string_f); Then the function pushes the HTTP response header into the packet buffer as follows: // Send HTTP content-type header plen = es.ES_fill_tcp_data_p (buf, 0, PSTR ("HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n")); Now for the bit that actually sends you the value you re interested in. The packet buffer has the string "Sensor A:" pushed into it, then the counter that was defined earlier is used to loop through the value array for this particular sensor and push each element into the buffer. While that is happening the packet length variable, plen, is incremented so it will correctly reflect the number of characters in the buffer. Finally, an HTML tag is appended so each row of data will appear on a separate line, and the whole shebang is repeated for each of the six sensor channels. // Read sensor A plen = es.ES_fill_tcp_data_p (buf, plen, PSTR ("Sensor A:")); i=0; while (temp_string_a[i]) { buf[TCP_CHECKSUM_L_P+3+plen]=temp_string_a[i++]; plen++; } plen = es.ES_fill_tcp_data_p (buf, plen, PSTR (" ")); // Read sensor B plen = es.ES_fill_tcp_data_p (buf, plen, PSTR ("Sensor B:")); i=0; while (temp_string_b[i]) { buf[TCP_CHECKSUM_L_P+3+plen]=temp_string_b[i++]; plen++; } plen = es.ES_fill_tcp_data_p (buf, plen, PSTR (" ")); // Read sensor C plen = es.ES_fill_tcp_data_p (buf, plen, PSTR ("Sensor C:")); i=0; while (temp_string_c[i]) { buf[TCP_CHECKSUM_L_P+3+plen]=temp_string_c[i++]; plen++; } plen = es.ES_fill_tcp_data_p (buf, plen, PSTR (" ")); // Read sensor D plen = es.ES_fill_tcp_data_p (buf, plen, PSTR ("Sensor D:")); i=0; while (temp_string_d[i]) { buf[TCP_CHECKSUM_L_P+3+plen]=temp_string_d[i++]; plen++; } plen = es.ES_fill_tcp_data_p (buf, plen, PSTR (" ")); // Read sensor E
