Storing data permanently in Portenta Machine Control

[h_se]

Hi Guys,

I am using a Portenta Machine Control(PMC) board and I have created a LCDMenu. So,I am trying to store some data that can be changed from the menu(for eg, Motor speed) permanently, meaning after power off - the last value that was assigned in the menu for motor_speed is stored and after power on - the value that was stored is read.

However, the PMC has no EEPROM available. So how could I store the values? Does anyone know any alternative ways?

Any suggestion would be helpful!

Best Regards,

Storing the data on an SD card would be one possibility

Hi @UKHeliBob,

Thanks for your reply!
Do you mean the SDRAM? The PMC does not have a SD card slot.

@h_se

The PMC does not have a SD card slot.

I was thinking more in terms of an external SD card reader

I would take it into consideration. However in respect to my project, it is not highly feasible.
Is there any other way?

could you interface an FRAM?

That could be a viable option. Currently, I also am planning to connect an external EEPROM via I2C. However, with both the EEPROM and FRAM, are there libraries that support the mbed architecture?
