| STACK_USE_MPFS + MPFS_USE_EEPROM |
 Posted: Sat Apr 17, 2021 9:45 am |

Hi guys,
I want to use a dedicated external eeprom for the web pages. Because above 7KB web storage, I'm getting TRAP_CONFLICT. I need to store min 14KB.
Ther are 3 pcs 24LC512 chips on I2C bus. So one will be dedicated for the web pages.
My Questions:
1) How can I set the address of specific eeprom for the MPFS?
2) What settings are required? STACK_USE_MPFS, MPFS_USE_EEPROM, MPFS_RESERVE_BLOCK and else?
3) What is the difference between STACK_USE_MPFS and STACK_USE_MPFS2?
MCU: PIC24FJ256GB106

Hey there!
If I may ask first -- can you compile your project with test web pages and get it to work writing it to PIC FLASH?
I ask because last I knew, the CCS TCPIP stack (which was modeled after the old Microchip TCPIP stack version 3.75(?) didn't work on the PIC24/33/32 series CPUs.
If you have got it working -- and now you're just moving to web pages on FLASH, let me know.
I'll go look at my old code for external FLASH (although it was on a PIC18F97J60) to see how I had MPFS set up. (I was using a 2MB external FLASH for my web pages.)
-Ben

Ok, I'll answer these out of order...
3 - MPFS2 was the successor to MPFS and if you can, usually you want to use MPFS2.
1 - from my quick review of my code and the MPFS1/2 docs, I2C FLASH isn't natively supported. (that I see) That's not to say you can't add it -- but it would answer your question as to "how do I address it" -- you're going to have to write the hardware level driver for the FLASH memories you're using.
2 - in my project, I have
STACK_USE_MPFS2
MPFS_USE_SPI_FLASH
MPFS_RESERVE_BLOCK (4096UL)
MAX_MPFS_HANDLES (13UL)
Hope that helps,
-Ben

Hi bkamen.
Yes I can run web pages up to 9KB without any problem. Thanks for your information. I will test with SPI and will try to write I2C library. It might be slower than SPI but I don't care it for now.

| If you can guarantee no interruption in chip power - i can show you how to use main data memory to hold your data instead of EEPROM - surviving PIC software resets and all. But not a cold power off. For this scheme to work - you need to keep chip power on for as long as the data you load into the space matters to you. Other smaller configuration data that needs less frequent accessed can still live in EEPROM. I use this method to save / modify up to 2400 bytes of data -battery backed -on a 18F46k22 all loaded in by RS232 + with check values at power up of the device. With one chance in 2^32 of falsely indicating data validity. |
