Forum Post: Are there any requirements on the device clock input related to the DCAN module? (CAN network timing related?)

Anthony F. Seely

Are there any requirements on the device clock input, (or tolerances on the crystal used with the device) related to the DCAN module?

Forum Post: Does DCAN_INTPNDX bit is set unconditionally upon successful transmission of DCAN Message irrespective of TxIE bit of the respective Message Object?

Pashan

Hello, In the TMS470R1VF3382 devices with SCC CAN Controller, there was a TA bit for every Transmitted Message Object [spnu197e.pdf]. I am trying to implement similar behaviour of Transmit_Message_Acknowledge within DCAN. How do I perform the similar function of Transmit_Completed in Polling...

Hi Tony, We tried to replicate this scenario and we do not see any issue from our side with your settings as you have explained above: - 2 Nodes - 2 Mail boxes [0x5 (configured for ID 0x222)and 0x10(configured for ID 0x229)] I assume the configuration on the receive side is as on the transmit...

Tony Morrell

Hi, I have two DCAN message objects configured with all parameters the same except for the 11-bit arbitration id (in DCANIF1ARB). Message object 5 is the first receive message object configured and is the lowest numbered (i.e. highest priority receive message). Message object 10 is configured following...

Forum Post: TMS570 CAN bit rate calculation

Luffy Li

Hi, everyone, We’ve met a problem in TMS570 CAN bit rate calculation, could you help me to check it? Thanks! As we all know, the Prop_Seg, which is part of the bit time, depends on the delay of driver ,the delay of the receive circuit and the delay of driver line. In my opinion, the delay...

Forum Post: Re: CAN Bus TX-RX

Jean-Marc Mifsud

Gil, I did some test to reproduce your environment and I don't see your problem. In DCAN to enable the external Loop Back mode, you have to: 1] Set TEST (bit7) in DCANCTL at offsett 0x00. 2] Set EXL (bit8) in DCANTEST at offsett 0x14. While in this mode, the DCAN will be able to transmit...

I don't know if this is already reported. I did not see one. There is a strange defect in CAN driver code : /** @file can.c * @brief CAN Driver Source File * @date 15.dec.2011 * @version 3.00.000 ..... */ The following busy wait loop is sprinkled throughout the code, /** - Wait until...

Diwakar Bansal

Hello Lorenz, Sorry for the delayed response. - MII does not support GIO functionality. - DCAN does support GIO mode, which can be used prior to DCAN initialization and DCAN node participating on the bus. But it is not recommended to switch back from functional to GIO mode once the DCAN communication...

Forum Post: DCAN Initialisation Corrupted in DCANTIOC/DCANRIOC on write to DCANCTL

Tony Morrell

Hi, I have a problem with DCAN module initialisation. In the following code snippet I set DCAN initialisation mode by write to DCANCTL with CCE = Init = 1. I then configure both Tx and Rx by write to DCANTIOC and DCANRIOC. I then exit initialisation mode by writing to DCANCTL again with CCE = Init...

Hello, I'm trying to configure DCAN and DMA to move incoming messages from the IF3-Registers to an address in RAM. Therefore I connected DCAN1 (with MessageBox1 as TxD) and DCAN2 (with MessageBox1 as RxD) and set the Update Enable Bit for the DCAN2-MsgBox1. To enable DMA Request for DCAN2IF3 I set...

Hello, Within DCAN there are registers called IF1CMD, IF2CMD Within those registers, there is a bit called BUSY. This above mentioned bit is set to 1 whenever CPU writes the MESSAGE NUMBER field of the above registers. Is that the one and only one condition due to which this BUSY bit will...
