Use key press / control change events in LabView and send the data over UART only during the event.
Ideally you should put the whole VISA functionality into separate VI or class and talk to it with custom events or queues. If you don't do this you may experience freezing the screen or other...
Hi, the mean intensity you get from the acquired image is correlated with the light intensity. Depend on the camera you use you can calculate the light intensity, ensure the camera auto exposure is turned off.
Getting the formula to calculate the light intensity in Lux or Lumens could be very...
The best approach is to add UART bridge with two circular FIFO inside to ensure that no data was lost. Simple Atmel Mcu can do the job for you, if there are not enough UARTs inside - make software UARTs
Are you talking about embedding virtual processor core inside the FPGA and use C programming? Altera virtaul processor is called NIOS, some FPGA even have built in ARM multicore processors.
Of course KlausST is right - there is no way to program the FPFA logic with C language, VHDL is...
To get working Ethernet IP you need the full (subscribed) version of Quartus + IP . When you buy the Quartus from some Altera dealer you can also get detailed information and support. The Altera dealers can answer many of your questions and also support your development, they can also connect...
There is special Altera IP for Ethernet (unfortunately paid), NIOS is mainly used to load the registers (IP address, timings, etc.) and to handle the communications on higher level. With this Ethernet IP you could achieve 1Gb/s data transfers even on much smaller FPGAs.
Re: soldering flexiable pcb
Hi,
What you have is flexible PCB with silver paint tracks and crimped end connectors, I used such connectors for capacitive keyboards many years ago.
So changing the connector will require to "un crimp" the terminals and crimp the new terminals. Using soldering iron...
I never played with UDP but it should be simple:
1. On the remote module you create the packet of data for sending over UDP. Each variable should go into some fixed place in the packet (for example temperature - bytes 10..18, time - bytes 19..27. etc.)
2. Send the packets from the module by...
You can use XMega parts with big success. PIC controllers divide the clock on 4 to execute instructions (so 20 MHz clock results in 5 MIPS performance) where AVR parts use directly the clock - 20 MHZ results in 20 MIPS. So even smaller AVR controllers like ATMEGA88 which run on 20 MHz can...
Hi FvM
I agree with you - in case of fixed frequency he needs just to check for Doppler radar for beating frequency
https://en.wikipedia.org/wiki/Doppler_radar
But in case of fixed frequency the only one thing he could get from beating frequency is the relative speed of the object. In case of...
