Thanks for the good information. Don

Thanks again Mark for your help. Hex is a new to me. Don K9AQ

I am scaling back the use cases for my CAN bus interface to a Huawei power supply so that I no longer will be reading and decoding the CAN bus data frames but just sending data frames. I have been sending 0x108040FE 00 00 00 00 00 00 00 00 which...

The Huawei power supply responds to request data frame with 13 data frames containing power supply values. These data frames are seperated by 3-7 ms with a total time of 49 ms. I have a standalone sketch that is sending out the request data...

Thanks to a lot of help from this forum, my sketch can now recieve and decode the data frames from the Huawei power supply, when I am NOT sending out the request data frame from my sketch. Instead I am sending it out from my USB CAN Bus...

I found on the Internet that the scaling factor for all of the data frames, except one, is 1024. My voltage with that scaling factor is almost exact. The maximum current has a scaling factor of 30. I have not tested this yet. My plan is to...

Thanks to everyone for your help. Simple mistakes that I should have caught. Don K9AQ

Collin, I added the switch case statements using the received frame variable of msg. I get the following compile error "Compilation error: no match for 'operator[]' (operand types are 'CAN_message_t' and 'int')" I am sure that I am missing...

Collin, Thank you so much, this is what I was looking for. Don K9AQ

My CAN Bus interface from my Teensy 4.1 to a Huawei R4850g2 is receiving and filtering the data frames that I want from frame ID 0x108040FE. The following are two of the data frames: Received on CAN3: ID=0x1081407F Data=1 75 0 0 0 0 C7 AE 75...

I was able to confirm that the CAN protocol is the same for both models. I need a back up supply so I think I am going to buy an R4875G. My amplifier is a dual BLF188XR with water cooling . I don't need a 4KW power supply but it would give me...

Mark, Thanks for this info. There is good info in here that seems to also apply to the R4850. Don K9AQ

I used an "if" statement to only read the message ID that I was looking for. It works very well. Don

Thanks for the information. I will take a look at that thread. I am curious what the purpose of these data frames is.

I am sending and recieving data frames to and from the Hauwei power supply. In addition to the data frames that I want, it is also sending out 0x1001117FE which I don't need. This frames is being recieved continuously. Is there a way to...

Thanks Mark that worked! Don K9AQ

I need to write a function that will communicate with a Huawei R4850G2 power supply using its' CAN Bus interface. I am using a Teensy 4.1 and a printed circuit board from a 3rd party source that connects the Teensy 4.1 to a SN65HVD234 CAN Bus...

Thanks. Don

I am working on a project that includes the use of a Huawei R4850 power supply, which has a CAN bus interface. Through the CAN bus interface I can monitor the power supply voltage, current, temperature, etc., and also vary the output voltage...

Thanks Paul. Great explanation. Don

I am not familiar with the second library directory and how it got there. In the past I have always had my libraries in documents/arduino/library Which library should I be using and should I rename the other one?

I am new to the Teensy world but have been an Arduino user for many years. I recently downloaded the latest version of the Arduino IDE and the Teensy 1.5.9 add-on. I was able to load and complie the very basic LED sketch but my next project...
