1. Create a new project

Double-click to select CANFD500kBaud/4MBaud

The new page is as follows

2. Create nodes through DBC

Select the storage location of dbc

Right-click Network nodes, create switch and light nodes


Create Message, fill in Name, the smaller the ID value, the higher the priority (light does not need too high priority, the allocation is three digits)

Create Signal, just DLC It is 1, 1byte=8bit, and the length range here is 1~8.

Drag Signals to Messages

and then drag messages to switch to save.

Right-click database, import Wizard, import the newly created dbc,

select the dbc just now, and The node moves to Assigned nodes

Signal transmission using CAPL programming

Double-click the light node to create a new can file. After the switch receives the signal, the light sends a signal

on sysvar switch_light_namespace::sl_switch{
  //先获取到switch变化的msg信息
  message switch_light_msg switch_light_msg;
  //将变化后的信号值赋给signal
  switch_light_msg.switch_light_sig=@this;
  //返回msg信息
  output(switch_light_msg);
}

on message switch_light_msg{
  //让LED的信号值去等于开关变化后的值
  @switch_light_namespace::sl_light=this.switch_light_sig;
}

run
