Nevermind. I'm using SD capability and have a card plugged in. It looks like I need to remove the resistor R167.

I have a WROVER 4.1 Dev Kit, and I'm trying to get the LCD to work. I tried downloading the following examples from github:

https://github.com/espressif/WROVER_KIT_LCD

The examples run, but the screen has nothing on it (it's just backlit). Is there some other configuration I need?

Thank you for the excellent explanation! So I've learned a few things about SPI RAM, allocators, and Arduino. I'll post my findings in another thread.

I’m getting memory issues with the WROVER, but I’m fairly certain I have plenty of available heap. Having said that, I probably have a misunderstanding of memory mapping and PSRAM. I have a WROVER DEV kit v4.1 running BLE scams using BLEDevice library in Arduino. I’m currently running Arduino 1.0 re...

I’ve tried 10K to 40K, but I get the same result. The log output says there’s 4182376 free heap before TLS. TLS requires that much heap?

Anyone?

First of all, I really think the ESP32 chip is amazing! I am currently proof of concepts in Arduino targeting various dev boards (WROVER and WROOM). At some point, I may consider going into a production environment with these chips, and I do realize that at that point targeting the native chip will ...

I have 2 FreeRTOS tasks where task 1 executes BLEDevice::init() and task 2 uses HttpClient to send a request to an HTTPS backend. I am running on a ESP WROVER DEV Kit v4.1. I run the first BLE task and it executes fine; however, once the WiFi task executes (after the BLE task), it throws the followi...

I'm barking up the wrong tree here... I moved my HTTP code to a task, and I was able to get it working just fine. This chip rocks!

Chip: ESP32 WROVER-B Dev Kit IDE: Arduino I'm getting Stack canary watchpoint triggered (loop task) while running some WiFi code on Arduino. I'm guessing it's due to the HTTP JSON serialization/deserialization routines; however, the allocations are not that large. I'm even using using std::vector......
