Webserver2 example (CCS 3.3v Ethernet development Board)
PostPosted: Sun Sep 07, 2008 6:23 pm     Reply with quote
Has anyone got the webserver2 example to work with the files stored on an SD Card?

I am using PCHW V4.078 and the TCP/IP is 8/2007

I have 2 SD cards that I am trying
1. sandisk 1g this one is a microSD to SD adapter
2. patriot 2g SD card

Both formatted FAT32 with 512 block size

I think the code has the wrong defines for the SELECT line for one or both MMC or EEPROM

What is the correct select line for the EEPROM and the MMC slot

I see this #define in ex_st_webserver2.c
Code:

#if STACK_USE_CCS_PICEEC
 #define EXT_FLASH_PIN_SCL     PIN_C3 //o
 #define EXT_FLASH_PIN_SDI     PIN_C4 //i
 #define EXT_FLASH_PIN_SDA     PIN_C5 //o
 #define EXT_FLASH_PIN_SELECT  PIN_C2 //o
#endif


I this the EEPROM select line? the code hangs if

#define STACK_USE_FAT 1

without defining

STACK_USE_EEPROM FALSE

I could not get this this to work so trying to minimize code i tried the ex_fat.c

Code:

#define MMCSD_PIN_SCL     PIN_C3 //o
#define MMCSD_PIN_SDI     PIN_C4 //i
#define MMCSD_PIN_SDO     PIN_C5 //o
#define MMCSD_PIN_SELECT  PIN_C2 //o


which claims
//These settings are for the CCS PICEEC development kit which contains
//an MMC/SD connector.

I get no errors from ex_fat.c even without a MMC/SD card in the slot. If I do a dir cmd it is empty if I do make test.txt then dir that file now shows up in the dir.


So what is the Select pin for MMC/SD connecter and the 32k of eeprom on this board?

Any other ideas?

Hi, i tried to use that example to work with PIC 18F4620+enc28j60 with internal memory to store the web page. I faced problems such as slow respond from the board...did anyone try to with this package b4?
