    Hi,

    as already explained, when the synchronization is enabled, all the submodules are managed as a unique driver with 8 channels (ch0 = A0, ch1 = B0, ch2 = A1, ch3 = B1, ch4 = A2, ch5 = B2, ch6 = A3, ch7 = B3). So, if you want to enable the outputs A1 and B1, you have to activate in the PWM configuration the channels 2 and 3 (see Sync_Conf.JPG in attachment). In attachment you can find the modified version of your project in which I have enabled the channels A0, B0, A1 and B1 (in particular, I have configured B0 as the complementary of A0 and B1 as the complementary of A1). In the picture Sync_PWM_Waveforms.JPG you can see the output waveforms.

    Best Regards,

    Hi,

    I have verified your project and it works fine on my side. Please, consider that if you want to use 2 different CANs, both MUST be connected on a dedicated transceiver, and the transceivers MUST be connected with CAN peripherals able to receive the messages sent by your code (the can_lld_transmit cannot send a message if the previous one has not been received yet) . On our SPC56xL Discovery there is only one transceiver that can be connected with CAN0 or CAN1 using jumper JP19 and JP22. So, only one CAN can be used to transmit at time. If you want to use a second CAN, you have to use an external transceiver.

    Hi,

    the starter kit is the free of charge version of UDE PLS. The full version requires a specific license. I guess the activation key is the key provided when you buy a license. In any case, for any specific item related to UDE PLS, please contact to the PLS support.

    Hi,

    sorry for the delay. As already specified, if you want to use advanced debug features, you have to move on pro versions of debuggers like UDE PLS or Lauterbach. you can find all the information about them on the related producer web sites.

    Hi

    currently the EEPROM Emulation Driver is provided only for the SPC56EL70L5 and not for the SPC56EL60L5.
