[RTT & Infineon PSoC6 evaluation board (with touch)] 10, emulated EEPROM test [Copy link]

Use the FLASH inside the microcontroller to emulate EEPROM, which can save an EEPROM chip. After all, the main thing now is to make money to eat.

Select New Project in Modustoolbox, then select the -062S2 board, and choose to create a Modustoolbox APP project:

Select: EEPROM

After building the project, directly remove cycfg_system.c and remove a define: //#define CY_CFG_SYSCLK_WCO_ENABLED 1

Then compile and run:

You can see that every time I restart, the number increases by 1. This means that the EEPROM simulation is successful.

This program can be seen in the Modustoolbox environment:

 /* The EEPROM content is valid. Increment Counter by 1. */
        eeprom_read_array[RESET_COUNT_LOCATION+1]++;

        /* Counter is in ASCII, so handle overflow. */
        if(eeprom_read_array[RESET_COUNT_LOCATION+1] > ASCII_NINE)
        {
            /* Set lower digit to zero. */
            eeprom_read_array[RESET_COUNT_LOCATION+1] = ASCII_ZERO;
            /* Increment upper digit. */
            eeprom_read_array[RESET_COUNT_LOCATION]++;

            /* only increment to 99. */
            if(eeprom_read_array[RESET_COUNT_LOCATION] > ASCII_NINE)
            {
                eeprom_read_array[RESET_COUNT_LOCATION] = ASCII_NINE;
                eeprom_read_array[RESET_COUNT_LOCATION+1] = ASCII_NINE;
            }
        }

        /* Only update the two count values in the EEPROM. */
        eeprom_return_value = Cy_Em_EEPROM_Write(RESET_COUNT_LOCATION,
                                               &eeprom_read_array[RESET_COUNT_LOCATION],
                                               RESET_COUNT_SIZE,
                                               &Em_EEPROM_context);
        handle_error(eeprom_return_value, "Emulated EEPROM Write failed \r\n");

Cost is king now, and saving an EEPROM chip is very cost-effective.

As long as the program is not too large, Flash is useless.
