intrepidcs / icsneoapi Goto Github PK

Hello,
I'm now using intrepidcs devices with this API in Linux system, basic functions work very good, but i found that it is missing SetBaudrate function of each CAN Channel in this API, without it, i can't read CAN messages in CAN BUS with specific baudrate. Checking the functions of 'libicsneoapi.so', just a few functions are supported.
Exist functions list are:
00003188 T icsneoClosePort
000030e8 T icsneoFindNeoDevices
0000331c T icsneoFreeObject
000031b4 T icsneoGetMessages
00003228 T icsneoGetTimeStampForMsg
000034cc T icsneoInitializeAPI
0000332c T icsneoOpenNeoDevice
00003058 T icsneoShutdownAPI
000031f0 T icsneoTxMessages
0000325c T icsneoWaitForRxMessagesWithTimeOut

I also checked the API descriptions in intrepidcs website, there should be a SetBaudrate function in the API, Can you pls help to add it to this github, it's very important to our project.

Many thanks,

Best regards,
Jeremy

Hi!

Since your documentation is not yet updated, I can't find any reference on what Network IDs to use for the FD channels of ValueCAN 4-2

I know for sure that the CAN1 and CAN2 are HSCAN and MSCAN since those are used for ValueCAN3, but for ValueCAN 4-2, I can't decipher what Network ID names to use for the 2 FD channels.

Can you please help?

Thank you!

Trying to use ValueCAN as a SocketCAN device on the nVidia Jetson TX2 development board, Ubuntu 16.04 LTS, but icsneoapi won't compile (output below).

I installed the dependencies libftdi1, libftdi-dev, and Linux kernel sources. Then I built intrepid-socketcan-kernel-module and it loaded successfully. But I'm trying to build icsscand and it requires icsneo, which won't compile.

Hi,

I am working on Linux environment and my project requests GetRTC and SetRTC function. Is it possible to support them?

Thanks,
Frank

Where can I retrieve the ESI Bit from the icsSpyMessage? Will it be StatusBitField? I can't get anything from the docs.
Sorry for the inconvenience. Thank you.

When using python_ics to send CAN message, I got following error. This issue is not 100% reproduced but the reproduce rate is pretty high. I didn't see this error on Ubuntu 14.04. Could you help to take a look?

Why was the Handle's data type in the API functions changed from int to void*?

Now I'm having a hard time using it with my C++/CLR project. Previously it was int so I don't have any problem. But now it's void* and is giving me a headache.

Are there any workaround for this? Thank you!
