ESP-WROOM-32 to ESP32-WROVER upgrade

Postby devang.dixit » Tue Aug 21, 2018 7:09 am

I have a multi-tasking wifi application currently running on ESP-WROOM-32, can I run the same application on ESP32-WROOVER?
If not then which type of changes is required?

Yes, given you do not use GPIO16/GPIO17, as these are used for PSRAM on the Wrover module. Aside from the additional PSRAM, the units are the same.

I have a multi-tasking application which uses wifi, which is running on ESP-WROOM-32. Can I use the same application on ESP32-WROVER?
What are the changes to be done to run the same application on ESP-32-WROVER?

Nothing needs to be changed. If you want to use the additional ram you may need to modify parameters with make menuconfig. Also I found that if the SPI is running at 80MHz you may need to slow it to 40MHz. That might be the thing that makes your current app fail on the the WROVER.

I merged your two threads, by the way. Keep your (similar) questions in one thread next time, please.
