Adding external SRAM to Arduino Microcontroller display on SimpleIDE?

Just a quick question…does the external SRAM memory amount show up on the SimpleIDE console (the box underneath the code)? I’m just trying to confirm if I’m supposed to see the external SRAM during run time or assume its added afterwards.


While compiling codes on UNO-NANO-MEGA-DUE, the IDE shows the % of the usage of the internal SRAM of the respective controllers.

UNO has no external Bus (address, data, and R-W/) to connect standard SRAM; however, SRAM can still be connected with UNO through IO lines.

MEGA supports the creation/simulation of external ADC (address, data, and control) Bus to adapt additional external SRAM chips.

Hi GolamMostafa,

Thanks for the information!
