    Well...with a programmer! And you have the choice: EPB (programming board), DVP (emulator + programming board), or third parties programming tools (INDART kit from SOFTEC for example)...

    Cheers!

    Another great option is the STICK. It is a dongle which is attached to the application board using ICC connector. It can be used to program any ST7xxxx device! The programming software is the same as for EPB's and DVP's - STVP7, unlike the inDART kit which uses the Datablaze programmer provided by Softec.

    Hi,

    A great feature of SofTec Microsystems inDART-ST7C tool is the possibility to program and to debug in real-time your software via ISP connector. Please give a look at www.softecmicro.com.

    Take a look at www.spen-soft.co.uk where you can download a fully functional ST7 programmer (with schematics & source-code).

    I want to program the flash memory just like the EEPROM.

    set LAt bit

    write to memory

    set PGM bit to program

    Is there an analog system for the flash ?

    Hello,

    Take a look at the application note AN1576.

    I don't understand what you mean by ''analog system for flash''.

    Ciao.

    I mean,

    you can program the EEPROM like this:

    set LAt bit

    write to memory

    set PGM bit to program

    Is there a way to do the same with FLASH ?

    Hello,

    It is..what we call In-Application Programming. The program writing data into the Flash is written into the RAM and executed from there. The apllication note AN1576 should give you a good idea.

    Rgds..

    Actually, I need to write a program that tests the FLASH of the st7c2334.

    I need to program al the memory bytes to '0' and than check.

    I need to program al the memory bytes to '1' and than check.

    If the checks correspond, the flash is ok.

    Has anyone got an idea how to do that ?
