Hello,

the two screens "CAN Min/Max" and "CAN Voltages" use the same raw data, it is only a different way the data are presented.
If GND of all devices is the same:
A recessive CAN-level is ~ 2.5V for both CAN-H and CAN-L.
A dominant CAN-level is ~ 3.5V for CAN-H and ~ 1.5V for CAN-L.
The analog ...

Hello,

I'm still not sure what you want to do. Was my assumption from my last response correct?

The function "hysteresis" compares a signal with two discrete values. If an input rises above "upper border", the predefined "high output" is set into the output signal, if the input value falls below ...

Hello,

do I understand you correctly:
you want to receive a Signal from the CAN-Bus that has values like 100, 200, 300 (therefore: bitlength on the CAN-Bus is at least 9bit), and then send a modified signal with values like 10,20, 30 onto the CAN-bus?

There are several options to do this:
1 ...

Hello,
could you please explain more details about your setup?
Baseboard DIgital1 has 8 Lowside drivers. If you want to see the output levels with a scope, please connect a PullUp resistors (~10kOhm) from an output to a supply (e.g.12V if you use a 12V Power supply). Without a Pullup you will always ...

Hello,

clock is based on a crystal with a frequency tolerance of 30ppm and a frequency stability of 30ppm within temperature of -40°C to +85°C. Thererfor the input clock can vary by 60ppm. The CAN output clock is created by using several digital dividers that do not change the accuracy.

Hello,

for a better explaination I will add some examples to explain how the duty cycle is created:

The timer responsible for the PWM genaration runs with 10MHz. If you want to have a PWM output with a frequency of 1 Hz, you can imagine a counter that counts from 1 to 10,000,000. If a 20% duty ...

Hello,

the two frequency outputs are based on a 10MHz timer. The equivalent resolution depends on the selected output frequency.
Example:
Output frequency for the PWM signal is set to 1kHz.
10MHz/1kHz=10000.
Equivalent bit resolution: log(10000)/log(2) = 13.29 => 13bit
With a 100Hz PWM frequency ...

Hello,

if you call "CAN_UserRead()" you will get a received message from the receive fifo (or nothing if the fifo is empty). This message is then removed from the receive-fifo.
In your code you call
CAN_UserRead ( VEHICLE_CAN_BUS, &RxMsg)
at the beginning of the main-loop, and again cyclic every ...

Hello,

for a test I have created a function that sends "number" CAN-Messages and counts how often the write-attempt to the tx-queue was not successful.A 32bit number is incremented with each message, in case the number of receive messages are smaller than expected it is possible to check a trace ...

Hello,

the hardware is prepared for an external transceiver, but the released firmware does not support this feature.
Your schematic looks OK.
Please send a Message to our support to get a premilary firmware that supports the external transceiver.
