Re: ESP32 TFT display library

Everything should work with the updated library the same as with the old one. The display cannot be added to the "wrong bus". The bus used is defined at the begining of the tft_demo.c . The default bus is now 1 (HSPI), maybe it was 2 before, but it should not affect the operation. Please c...

Re: ILI9341 not working

Hi Loboris, I am trying to combine the SD card example code (included in the esp-idf) with the ili9341 TFT library to display my images to the screen from the SD-card. I had the SD card example working both in SPI mode and SDMMC mode, but want to use the SPI mode, because it takes up less connectio...

Re: Need help for XML file parser

XML structure is quite simple, it should be easy to create the xml file 'manually', if you don't need very complex xml.

Re: ESP32 WROVER pSRAM Quiescent current

Maximal standby current of ESP-PSRAM32 is 50 uA, but it is powered by VDD_SDIO and is powered down before entering deep sleep (same as Flash chip).
As a result, there is no difference in current consumption in deep sleep between ESP32 WROVER and ESP32 WROOM Module.

Lyontek LY68S3200 4MB psRAM works fine with ESP32.
It is used on AnalogLamb's ALB32-WROVER module.

Re: Need help to connect external 16 MB SPI Flash Memory on ESP32-WROVER Kit

Are you suggesting to use 1.8 V supported external 16 MB SPI Flash Memory instead of 3.3V supported memory if we plan to connect separate SPI Flash Memory? I think you must use 1.8 V external 16 MB SPI Flash Memory if you plan to connect it as external flash. It would certainly be too time-consumin...

Re: Need help to connect external 16 MB SPI Flash Memory on ESP32-WROVER Kit

You need to remove the shield on ESP32-WROVER module, then it is quite easy to replace the flash chip. You must use the 1.8V chip like: W25Q128FWSIG from US distributor - expensive or W25Q128FWSIG from China distributor - cheap You can use the same chip as external SPI Flash. You can't " calibr...
