To do a quick 'loopback' test, connect the RX and TX pins together on one of the serial ports (for example Serial1), and then run the following code: Serial1.setup(9600, {rx:serial_pin, tx:serial_pin}); Serial1.on('data', function (data) { print("<Serial> "+data); }); ...
Hi Danyil rs485 is not supported by nxp in its bsps, please try to test without it, for example with uart loopback. For rs485 issues may be suggested to proceed with extended support of NXP Professional Services | NXP Best regardsigor 0 Kudos Reply Post Reply About...
