Let us demonstrate an example of RS485 serial data transfer between two Arduino boards using the MAX485 TTL to RS-485 module. Our aim will be to send ADC values from the master Arduino connected with a potentiometer through the RS485 module to the slave Arduino. The slave Arduino will be ...
|Arduino Example| **Versatile Connectivity for Your Projects** The TTL to RS485 Converter Module is a crucial component for anyone looking to expand their Arduino or AVR board's capabilities. Designed to bridge the gap between TTL and RS485 protocols, this module is perfect for a wide range...
Those of us here at Digilent don't have any experience with that particular RS485 chip or that library they are using. We have our own Pmod RS485 with an example code loopback code in itsResource Center, which will likely be a good thing to try to do with your particular chip. ...
