It is an architectural limitation of the flash that it can only be written in its entirety once when you program your sketch, so you can't write to it during the run of your program. Mikal Simon,

I’m afraid the scenario you hope for cannot be accomplished using Flash or any other library. It is an architectural limitation of the flash that it can only be written in its entirety once when you program your sketch, so you can’t write to it during the run of your program.

This Flash library is of great interest to me for a project that needs to access several kB of data. My question is whether one can create a flash object without declaring its value in the same statement. I would like to initialize the data structures and then send a bunch of values over the serial port to populate the array or table. Thanks for your help. Best regards, =Simon= Hello Mikal.

That's pretty old. I'm not sure I ever even tested Flash on that. Can you try upgrading? What other libraries are you using in your project? I wonder if there is some conflict. Mikal Mike,

I notice that you’re using Arduino 0012. That’s pretty old. I’m not sure I ever even tested Flash on that. Can you try upgrading?

What other libraries are you using in your project? I wonder if there is some conflict.

I get the error when I just have the #include and no calls to the library. /Users/Mike/Downloads/arduino-0012/hardware/libraries/Flash/Flash.o:(.data+0xa): undefined reference to `__cxa_pure_virtual' Couldn't determine program size: hardware/tools/avr/bin/avr-size: '/tmp/build2486.tmp/sketch_090608a.hex': No such file Thanks for your time, Mike Hey Mikal,

I modified a sketch for a camera remote release timer with an LCD and with a few pages to enter data in order to shoot several images. Unfortunately, when flipping through the settings pages, the code crashes. I know that the 2 arrays are using too much memory and causing this sketch to crash as there is not enought RAM. I was told to move the arrays into FLASH-Memory. I tried with the aid of the PROGMEM reference, but did not succeed writing the correct syntax. The problem I am having is that I am using 'unsigned long' variables and I just can't get the code right. Would you mind helping me on this? I'd highly appreciate it as I am more a photographer and less a code writer. The WEB-page for this project and the code is here: http://www.halo-photographs.com/remote-shutter-release-timer/the-arduino-code.html The arrays in question are on line 154 and line 157. Looking forward to your reply. Thanks, Hans. Hi Mikal
