From last week i am implementing SPI communication between two ESP-WROOM-32D. I am using the code examples given by espressif itself. C:\esp\esp-idf\examples\peripherals\spi_slave\sender ( Master) C:\esp\esp-idf

LILYGO T-Energy-S3 is an ESP32-S3 WiFi and Bluetooth IoT board with an 18650 battery holder, a USB-C port for charging and programming, and plenty of I/Os thanks to two 20-pin GPIO headers and a Qwiic connector. We’ve already covered alarge number of ESP32...
The ESP32-C5 was initially announced as a dual-band WiFI 6 and Bluetooth 5.0 LE SoC, but the user manual for the beta board indicates that it also supports Zigbee 3.0 and Thread 1.3, so there’s an 802.15.4 in the wireless microcontroller. The ESP32-C5 board itself features two SMA c...
So, other Wi-Fi devices can connect to that network (SSID: ESP32-Access-Point, Password: 123456789). The ESP32 client is set as a station. So, it can connect to the ESP32 server wireless network. The client can make HTTP GET requests to the server to request sensor data or any ...

SPI Master with Multiple Slaves To start communication between master and slavewe need to set the required device's Slave Select (SS) pin to LOW, so that it can communicate with the master. When it's high, it ignores the master. This allows you to have multiple SPI devices sharing the ...

Due to these extraordinary properties of perovskites a lot of efforts have been made for their applications in various optoelectronic devices such as LEDs, solar cells, and lasers3,8–12. Even though hybrid organic–inorganic metal halide perovskites e.g., MdrAawPbbaI3c,kFsAiPs ...
