soem_servo_motor_rt1180_bm
Overview
This example demonstrates how to use the Simple Open EtherCAT Master (SOEM) Library to control motor.
In this example there are 2 NXP EVK board:
SOEM as EtherCAT MainDevice running on EVK board(i.MXRT1180/FRDM-1186/i.MX943)
ecat_servo_motor example as EtherCAT SubDevice running on i.MXRT1180 EVK board

Running the demo
If the test passes, the motor will start to retate.
When the demo is running, the serial port will output:
NETC EP frame loopback example start.
Starting motion task
ec_init on netc0 succeeded.
ec_config_init 0
…
1 slaves found and configured.
ec_config_map_group IOmap:20000664 group:0
Slave 1, configadr 1001, state 2
…
Slaves mapped, state to SAFE_OP.
