Hi!
I am trying to send CAN messages from MATLAB to my connected ECU. I have a PCAN-USB FD (https://www.peak-system.com/PCAN-USB-FD.365.0.html?&L=1), so I start the channel (the third library is installed). Then, I open the database that contain the two message variables. Then, I transmit periodically the messages to this channel. (The code that I am running is below)
The problem is that when the data is transmited, the PEAK device is receiving these messages, but it does not transmit the messages to the CAN bus, for the ECU to receive them.
I don't know if I am doing something wrong, or if there is other way to communicate with my ECU using MATLAB and a PCAN-USB FD.
If someone know something about, it could be so helpful for me.
Thanks in advance.
Óscar.
%CAN TRANSMITED DATA TO THE USB
txCh = canChannel('PEAK-System', 'PCAN_USBBUS1'); % Construct CAN channel connected to specified device
start(txCh);
%%
db = canDatabase('file.dbc'); % Open the database and attach it to the CAN channels
txCh.Database=db;
msg1 = canMessage(db,'ECU_1'); % Definir el mensaje a extraer de .dbc
msg2 = canMessage(db,'ECU_2');
transmitPeriodic(txCh,msg1,'On',0.05); % Transmitir el mensaje a determinada frecuencia
transmitPeriodic(txCh,msg2,'On',0.05);
%%
msg1.Data= data_calculation(50);
msg2.Data = msg1.Data;

You need to set up correct speed for CAN interface before use it.

I have the same issue as the orignial post. What do you mean by set up correct speed for CAN interface? The default bit rate should be fine for what Im trying to transmit, yet PCAN is receiving the meassages not transmitting them.
