Re: guru meditation error

Did you run the program with "make monitor"?
If not, give it a try. With a bit of luck it will display a trace log showing where the error occurred.

Re: Difference between ESP32-WROVER and ESP32-WROVER-B

What is the difference between ESP32-WROVER and ESP32-WROVER-B modules? Does ESP32-WROVER-B has more PSRAM than ESP32-WROVER? Hi, They both have 8 MB PSRAM. ESP32-WROVER has PSRAM that operates at 1.8 V and can support up to 144 MHz clock rate. ESP32-WROVER-B has PSRAM that operates at 3.3 V and ca...

Re: WROVER and PSRAM

If menuconfig option "SPI RAM access method" is set to "Make RAM allocatable using malloc() as well" then the memory allocation strategy will allocate memory where ever it wants, i.e., in internal RAM or external PSRAM. The allocation strategy will take menuconfig option "Maximum malloc() size, in b...

Re: IOT-Solution examples on ESP-wrover-kit V3

I was also going to suggest an LCD module with an ILI9341 LCD driver chip and an XPT2046 touch screen controller. One like this that actually has the XPT2046 touch screen controller soldered on. And not one like this that looks more or less identical but doesn't have the XPT2046 touch screen control...

Re: IOT-Solution examples on ESP-wrover-kit V3

The same thing happened to me too the first time I tried it :) Did you modify the correct line ILI9341_adapter.cpp? The line to modifiy looks like this: .bckl_active_level = 1, This line appears twice in ILI9341_adapter.cpp. The first occurance is for µGFX and the second occurance is for LittlevGL. ...

Re: IOT-Solution examples on ESP-wrover-kit V3

i need to know if it is possible to run IOT-Solution examples on ESP-wrover-kit V3? As a general rule it will not be possible to assume that each and every example will run unmodified on an ESP-WROVER-KIT V3. It will depend on whether the required hardware is present and connected to the ESP-WROVER...
