Dear all, I am setting up a 4 inch 800x480 TFT display with the NT35510. The LCD component for ESP32s3 and IDF 5.3.1 includes an example for such a display. Hence it is easy to get started. I have removed all code related to LVGL and touch. I use a ESP32-S3 WROOM-1U module. I have struggled to get s...

Thanks MicroController. The problem has been reported before and workarounds have been suggested. I have found one and it works for me, provided, I do the three steps right after creating a new project. I have not made any exhaustive investigation trying out several combinations. I hope this is read...

I use the VS-code (latest version) on a Windows 11 PC with the framework 5.3.1. When I start a new project and set the target to ESP32-S3, I get a message saying the environment variable is set to ESP32. The message is: Target 'esp32s3' specified on command line is not consistent with target 'esp32'...

Is it possible to fix the level on MOSI when reading lots of data using MISO? Ii is possible to use FULL DUPLEX and transmit on MOSI an array with all elements set to 0 or 1. The array has to have a size at least being the same as the array used for saving the data read on MISO. This is a waste of m...

I have found the error. I have used as flag SPI_DEVICE_NO_DUMMY within the transaction_t structure. That is wrong. That flag belongs in the spi_device_interface_config_t structure. I have moved it there and now 16 clock pulses are sent only. The subject is closed. Sorry for any inconvenience. Regard...

Using an oscilloscope reveals the 20 clock pulses are 4 + 16 i.e. there are 4 clock pulses send before the content of the 8-bit address. I have modified my code to use full duplex. In that case only 16 clock pulses are sent. That is a solution for me, but I would still appreciate receiving instructi...

Dear, I am not sure whether it is a bug or me (most likely me though). I use VS code and ESP-IDF 5.3.1. The board has an ESP32-S3 WROOM-1 on a DevKitC. I use the SPI element in master mode. I want to send an 8-bit address and in response receive 8 bit data. I have used my 4-channel oscilloscope to d...

I started running the USB host MSC example. Once created I ran idf.py set-target esp32s3. Then all dependencies were resolve and the example project worked perfectly. The project includes a folder managed_components. My goal is to replace the file system with my own implementation, hence I need to e...

Problem solved. I tried another USB 3.0 64GB flash memory stick. It was accepted by the software.

Looking closer, it is formatted as FAT32 (surprising). EXFAT is not enabled in the software example.

Thank you for the reply.

I have tried connecting my USB 3.0 flash stick, but it was not recognized. I use the ESP32-S3 framework 5.2.1 example USB/host/msc.
