QSPI on Renesas RA6E1

Extended SPI meaning and features refer to:
Renesas RA6E1 Group User’s Manual: Hardware: section on Quad Serial Peripheral Interface (QSPI)
Table 33.1 QSPI specifications.
Also see attached figure.
I am not aware of an example project of using a 25x QSPI flash memory for RA6E1.
However, I can give some pointers to achieve the result:
The other evaluation kit for RA4M2 has a project called quickstart_ek_ra4m2_ep included in the FSP example project bundle. Parts of C code demonstartes how Quad-SPI FLASH Write/Read is implemented. User interface is also implemented using USB code.
You will have to adapt this code to suit your requirements. The flash Write / Read code is in menu_ext.c file
As JB, RenesasRulz Forum Moderator suggested the QSPI module for FSP included in the qspi_ek_ra6m3g_ep folder has an example for QSPI.
This Example Project demonstrates the functionality of QSPI module using On board QSPI chip macronix MX25L in QPI and Extended SPI modes. The SPI Protocol is selected from RA configurator.Fixed data is written to QSPI Flash device and read back. Read and Write data is compared and the result is displayed on Jlink RTTViewer.
Additionally, you may want to look at QSPI (r_qspi) RA Flexible Software Package Documentation:

Facing issue while connecting EspressifESP32 with Android mobile using EspressifESP32 Wifi.
Are you setting ESP32 in AP mode, and the trying to connect your smart phone with the ESP32 SoftAP ? 2 meters shouldn't get the signal poor like that. Can you read the RSSI from the phones ? Which hardware are you using? Could it be that the antenna is missing ?

Free RTOS with USB-PCDC on Renesas RA6M3
It seems to be caused by the read buffer (g_read_buf) only being 8 bytes in size, whereas the max packet size for the full speed bulk transfer is 64 bytes. The USB driver sets up a 64 byte transfer with the DMAC when R_USB_Read() is called, then the DMAC transfer over writes some other data in RAM.

See lessWay to reduce the SPI buffer size.
If you use a RTOS-aware structure (like a ringbuffer, queue, whatever) then you don't need to delay: the push into the buffer will block for you while there's no room available. The amount of elements in a ringbuffer is limited by its size, so you can double, triple, however-many-le buffer the thingRead more
If you use a RTOS-aware structure (like a ringbuffer, queue, whatever) then you don’t need to delay: the push into the buffer will block for you while there’s no room available. The amount of elements in a ringbuffer is limited by its size, so you can double, triple, however-many-le buffer the things by simply increasing the size of the ringbuffer. Also, perhaps good to mention that by ‘ringbuffer’ I specifically mean the esp-idf ringbuffer construct, as that is RTOS-aware. If you use the bytebuffer mode of that, it would be good.

You can use the AMIC and DMIC, however both will effectively go through the ADC filters. If you enable the ADC_FILTER1, which has the voice and music filters both paths (AMIC, DMIC), will be effected by the filters.

The purpose of the SD pin is to provide an alert to the user that the power FETs have been turned off by the device. The PSD pin can be linked to fatal faults such as OVLO, UVLO and DVCF and be used to drive an external circuit that alerts the user to these faults, and/or blows a fuse. If either piRead more

If either pin is used to drive an external circuit care must be taken to prevent complete discharge of the cells.
See lessDiffernce between “Simple SPI” and “Standalone SPI”?
The "simple SPI" mode of the SCI is significantly different than the SPI peripheral. For example the simple-SPI is limited to only 8-databits while the standalone-SPI supports many different bit lengths. If your needs are met by what the simple-SPI supports there is no reason to avoid to using it.

The ESP-IDF codebase plus toolchain are available in ARM Linux flavour, so you could possibly try installing them in a chroot on the tablet. You can install Arduino as an ESP-IDF subcomponent as well if you want to use that API.

Touch sensor is for buttons like you see on a microwave keypad. LCD interface could be through SPI or maybe HS1 8-bit interface.
