CAN-bus (Controller Area Network-bus) is the broad name for a set of standards which define the way for separate but connected devices to communicate with each other. Its primary uses are in the industrial, automotive and aviation sectors due to its extensive error checking, flexible implementat...
Many devices can be connected to the CAN bus, ranging from complex electronic control units to simple I/O devices. Each device is called a node. Each CAN node transmits differentially over two wires: CAN High and CAN Low. Signalling CAN transmits differentially over two lines, CAN High an...
Use two oscilloscope channels, one for the master transmit lines and the other for the slave transmit lines. Where Modbus is transmitted over RS-422 or RS-485, use differential probing.Set memory length to enough to acquire as many frames as required, and with enough sampling resolution to re...
I want to know if a string exists in the list of array ignoring case sensitivityI have the following code working for my requirement, but its checking case sensitivity. How can use it ignoring case sensitivity...?复制 Dim SrtList() As String = {"abc","qwe","zxc"} Dim chkStr As ...
Question : How do I use "ping" to check my Oscilloscope’s Ethernet LAN connection is working correctly? Answer : In Windows 2000 or Windows XP click onStartselectRunin the “Open: window” typecmdthenclickOK. At the prompt typeping<space><name or IP address>of the ...
Read our guide (with video) on how to choose the best oscilloscope (also called an "oscope") for your unique needs, including bandwidth, rise time, sample rate, channel density and triggering
A possible solution can be to implement, for example, a RAM test on a part of the RAM that is currently not in use, while the application is temporarily redirected to use another part of the RAM that does not overlap with the tested area. 4.2 No co...
In response to MichaelF_56 Hi all I checked the signal I2C bus by using Oscilloscope. Why does the cycle of i2c is 10us (SCL is purple)? Is the frequency of cfa_xx functions 400kHz isn't it? (The cycle of SCL shoud be 2.5us, shouldn't it?) Furthermore, SDA which is yellow...
Step 2: Use the oscilloscope to measure the circuit on the circuit board to see if it is logical If the output is not logical, need to be treated in two cases, one is the output should be low, the actual measurement is high, you can directly determine the chip damage; the other is...
How does an oscilloscope draw a trace? This can be explained with the help of an example. So picture a scenario where one has a pencil in one’s hand at the zero point on a graph paper. Now your hand is strapped to two electric motors, both of which are in turn connected to electr...
