Two boards demo¶
Board #1 Demo file : esp32_uart_board1_demo.slx
Board #2 Demo file : esp32_uart_board2_demo.slx
This UART demo is used to communicate between two target boards using UART Blocks. Board #1 is the transmitter which sends the status of the three digital output pins of Board #2. According to the receiving data to the Board #2, it controls the digital output status of those pins using the Digital Output Block.
- 2 ESP32 modules
- TX pin (GPIO32) of Board #1 should be connected to the RX pin (GPIO33) of Board #2 and RX pin (GPIO33) of Board #1 should be connected to the TX pin (GPIO32) of Board #2.
What should be happening?¶
After two target boards are connected together with TX and RX pins, the LEDs which are connected to the Board #2 will toggle every 1s.
