Transmitting and receiving Datas with the esp32 buildin wireless ESP-Now option
Information:
Transmit a 32 bit (uint32_t) value and receive the data with another esp32 device, i.e test the 32 received bits to set GPIO pins and remotly control Motors, LED's...
Infrared Detection
Information:
Simple infrared detection without signal decoding, but with graphical display. A LED connected to a digital output pin is switched on if a specified threshold is reached.
Matrix Keypad 4x4 with PCF8574 I2C IO Expander
Information:
Matrix Keypad 4x4. Touchscreen (WT32-SC01) and/or external keypad (I2C interface with PCF8574) support.
Floating point calculator - Alpha Version
Information:
Floating point calculator (TFT resolution min. 480 x 320), supports negative values and also point before line calculation. Touchscreen (WT32-SC01) and/or external keypad (I2C interface with PCF8574) support. This is an Alpha Version and may be buggy!
5-Way Tactile Switch
Information:
5-Way Tactile Switch example, Buttons LOW active. Connecting to GPIO 34 - 39 of the esp32 requires a pullup resistor(10k) for each switch.
Joystick Analog
Information:
Analog Joystick, PSP2000/Nintendo Switch/Breakout Modul...
The TFT resolution must be 480 x 320 or greater
Notice:
I bought two replicas of a PSP2000 joystick at amazon, the quality is very, very bad, the parts are not usable! At the end a standard analog joystick breakout modul was used. That cheap part is far away to be perfect, but it is still usable for simple applications.
