read analog value

2024-10-16T19:43:48Z

Hi Konstantin,

Probably just a simple question but i can't find a good start of the answer within the docs or the forum.

Purpose for this is that we are reading data from the can bus . If the data exceeds a certain value the output needs to be triggered.
As this value depends on the needs of the operator, the operator can adjust the analog value (potentiometer).
The value given by this potentiometer needs to be read by the Canny7.0.

Is it possible to read an analog value (0-10v) from a potentiometer ?

can message missing several times when reading can bus

2024-05-04T09:21:25Z

Hello,

For a project i am reading several extended can bus messages from the can bus. One of the messages is broadcasted each 400ms.
This is quite a slow interval and now it seems that the canny 7.0 is sometimes missing this message. This results in a delay in switching due to the missing message from some times 1.2 or 1.6 seconds. (3 or 4 messages missing before detecting the message).

Other messages that i am looking for are broadcasted with a higher frequency of 30 ms and aren't a problem.
I also noticed when i am removing reading these messages from the program (only reading the 400ms messages) it improves the program and the 400 ms second messages doesn't seems to be missed any more by the controller.

In the attached file you will find the program.

1. Why is the canny logic 7.0 missing several of the 400ms messages ?
2. How can we improve the program so we don't miss anny of the 400 ms messages ?

Floating numbers

2023-11-11T16:08:07Z

I want to calculate PWM period based on a given RPM.
Frequency = RPM / 60.
Say I have 8 RMP / 60 Sec = 0.13333 Hz.
Period = 1 / Freq.
So the Period = 1 / 0.13333 = 7.5 Sec.
How to represent these calculations in CannyLab ide?

LIN BUS

2023-06-05T17:29:58Z

Hi all,

I am currently working on a Lexus BEAN MPX bus ( as shown in the attachment), it is running in ring mode ( MPX TX and MPX RX) , baud rate is 10kpps , at 12v logic level (reference to 0v ground) , I was looking at the physical layer compare to LIN and CAN, just curious if I can tap one of the HR DInput to sniff the signal ? all I wanted is to listen to the message content ( MES-ID and DATA 1-11) , is it possible?

Relay output - keeps combining channels when connected

2023-05-25T06:31:01Z

Need some help with this basic flip/flop circuit. I have the input on CH0, flip/flop conversion on and outputs to the relay on 6/7. In test mode, everything is working but when connected to the relay + inputs (for switching on/off), it seems to combine both channels. I'm a bit new to this but am impressed with the Canny's capabilities....probably overthinking the circuit. I've attached the circuit file also.

Thanks.....

can bus receive and transmit

2023-03-16T22:19:06Z

Hi to all i am new here i need some help i am working on my car i rewire a new stand alone ecu to it but my dash and other
parts stop working as it use can bus my new ecu can receive and transmit data but the problem is i cant scale it so my dash
read it correctly

example
ecu/11bit

1250 tx : d1 d2 d3 d4 d5 d6 d7 d8

d3+d4 16bit rpm * 0.01 scaler

dash
29 bit

0CF00400 rx : d1 d2 d3 d4 d5 d6 d7 d8

d4+d5*0.125

can i use canny7 to do this

receive 11 bit and transmit 29 bit with math

thanks..

CAN to RS232

2022-06-14T13:34:27Z

Hello

I have purchased a Cannylogic 7 to hopefully receive a frame from a CAN network at 1mbps and then trasmit it over RS232. Is there a standard example to cover this?

Thankyou

Congratulations! Great Project.

2022-04-20T10:05:06Z

I wanted just to congratulate you guys on the great job you've done with this product/project. I've bought 2 canny 7 controllers, and the quality is great. Simplicity and straightforward documentation are amazing. IDE is great. I didn't expect to accomplish a complex project without asking for support. Really amazed.

Given the circumstances of the war and all those sanctions on Russia, which are hurting us rather than the Russians, what are the options to buy more controllers?

Greetings from Albania.

Can Monitor filtering

How do you uncheck all of the check boxes in the top half of the screen so that you can then check one ID box and show only that ID's activity in the bottom half of the screen like you do at 4:32 minutes into your youtube video Dtc4XX374u4 . (Your software won't allow me to include the whole link.)

CAN Bus sending message without using DIO channels

2021-11-11T20:29:15Z

Hi,

I have seen that the example projects of receiving and sending messages to can bus all about using DIO channels, in the support section.

Is it possible to do a project like that; for example when 0x0224 signal is received, send 0x3BC signal to the can bus?

Similarly receive signal from LIN bus, use this signal in logic and then send to the CAN bus, or vice versa?

Thank you very much.

the operating temperature is -40 to + 85 ° C

2020-07-26T08:11:31Z

the operating temperature is -40 to + 85 ° C

la température de fonctionnement est de -40 à + 85 ° C

Après plisseurs tests, il s’est avéré que le Canny 7, commence sont disfonctionnement aux alentours de 45 °, température facilement atteinte dans un véhicule au soleil par exemple. Quoi faire ?

After testing, it turned out that the Canny 7 began to malfunction at around 45 °, a temperature easily reached in a vehicle in the sun, for example. What to do ?

Sending several CAN ID

2020-06-07T19:56:50Z

Hi,

I am new there, but hoppe to find a help.

I have two Challenges.

1. I wan to send several CAN ID the same time, how can I do that?
2. I want to add one bit on the message I receive and send it back on other ID

example:

Read ID 0001 6 12 14 45 67 58 10
send ID 0002 8 12 14 45 67 58 10 01 00

send ID 0003 8 23 34 56 45 45 23 23 24

Thank you!

Canny 7 Demo kit

2020-03-25T10:16:12Z

Good morning, everyone,
I bought a demo kit to learn how to use the cannylab.
I can't get the switches to work in input mode. After several tries I can't understand how to program this function.
I would like for example to use switch 0 in input mode to drive the leds in output mode of channel 1.
Can you help me ?
I consulted the wiki but I haven't found the solution.
Waiting for your answer.
Best regards.

Hi all

2020-01-24T00:18:42Z

Hi all I’m looking for some advice. I’m building a Replica car and I need to send CAN to my dash cluster like indicators warning lights ect.
And I’m looking for a unit to read existing can signals data coming from the BSI
Can you advise me if your units will help.

Thanks.

Sending sequence of messages as part of state machine

2020-01-18T22:47:38Z

I am trying to initialize and communicate with a electric motor controller on a CAN bus.

The protocol requires me to send and Init sequence of 3 consecutive messages with ID 0x000, length 2 bytes and the following content:
0x000 81 00
0x000 80 00
0x000 01 00
These need to have approx 20-40ms between them.

After these I need to send a Sync message with ID 0x080, length 1 byte and content 00:
So it looks like 0x080 00

I need to repeat the above (Init + Sync) until I receive InitReady message with ID 0x181 and content of 40 00 within it.

After the InitReady I need to only send the Sync message every 500ms and check that the 0x181 (InitReady) message has the 40 00 with it.

If I don't see the InitReady message within 1000ms I revert back to (Init + Sync) as above.

I tried several different strategies, but I think I am missing something.
Here is the cfd file I have made so far.

It seems I have problem syncronizing the ReadyToSend with the 20-40ms timespan between the 0x000 messages.
And from the simulation I can see that I have some issues with retaining the current_msg to the value needed.

Any help is appreciated!

Thank you in advance,
Nikolay
