Flowcode v9 ESP32 "Flash EEPROM"

Post by dvcam99 »

Hello FC community,

I`m looking for a way in order to store and receive byte values into ESP32 flash.

Unfortunately the Flash EE Prom Component is not working. I`ll get a compiler error.

Any suggestions is apreachiated and welcome.

Hi Dirk

I don't know if this will help you.
I have several ESP32s, each with a fixed calibrated sensor.
For each ESP32, there are values from the calibration machine that are stored in the Flowcode program.
I read the MAC address from the ESP32 and then assign the appropriate values.

read mac adress for matching data:

The esp32 doesn't really have any EEPROM - you can use flash memory as persistent store, or the RTC has some memory that is non-volatile too.. There is a post about SPIFFS and also using RTC memory - though will take a bit of searching..

Note that both these posts are quite old - and with the rapidly changing esp32 environment might take a little work to get going...
