CAN is not very high speed, so normal I/O pins on the FPGA (GPIO) can be used, but the FPGA pins are not electrically compatible with the CAN bus. Each controller needs an external CAN transceiver. It is not a problem to fit 4 CAN controllers in an FPGA. Search for "SN65HVD230" on Aliexpress or Ebay and you will find many boards that will solve th
I believe there's no single chip transceiver for 3.5 GHz, because it isn't a license-free communication band. You find many single chip solutions e.g. for 2.45 GHz. A straightforward solution would be to refer to a sofware defined radio platform, e.g. HackRF One or Rad1o.
Article is published in Ham Radio september 1974 1296MHz SSB transceiver page 8. This is a source of many articles or scheme that VA3IUL used.
many synthesizer generators are capable of fast frequency hopping, e.g. radio transceiver chips. The detail specification matters however, step size as well as settling time.
if you have wired 10baseT you can connect to many embedded systems, e.g. Microchip there is the PIC18F97J60 with onboard 10baseT or PIC32s with onbard 10/100baseT or PIC24/dsPIC with an external Ethernet transceiver such as the ENC28J60
what modulation are you using in the 2.4 ghz module? There are many nuances to multiplying a signal in frequency.
That module operates at 2.4GHz at 9600bps using a proprietary frequency hopping system. I do not think any smartphones that could directly receive a signal from that module. many smartphones have 2.4GHz radio's for wifi and bluetooth but I don't think they are compatible with the protocol used by that module. Without connecting extra hardware to
Hello all, recently I've been looking for wireless transceiver modules to interface with an MCU (atmel UC3C series) for sending telemetry at a high data rate (like 5Mbaud or more) at short distance (maybe 20m max). Previously I had used a nRF24L01 module and was able to get about ~1Mbaud throughput. Now I've looked at many 802.11 wifi modules (Xbee
For Sale: Loaded Elecraft K3 and P3 panadapter with many options including the second receiver and antenna tuner. It was a kit but expertly assembled and it works and looks great. Below is the complete list of options: K3/100 - 100w transceiver ......KBPF3 - gen coverage bandpass filter KDVR3 - digital voice recorder......KFL3A-500 - 500hz cw
ah.. thats new. gotta lay my hands on those. but on second thought , will stick with old school Yes, there are many possible reasons to use transceiver chips with a microcontroller of your choice.
Hello, The VSWR of an antenna only depends on that antenna, so if the transmitter's output impedance changes, VSWR should not change. Sometimes VSWR becomes worse due to increased harmonic (or spurious) production of the final power stage. Also many VSWR indicators show too optimistic VSWR values at low power, because of the diode voltage drop
Friends, How can I send serial data via 433Mhz responsively ? Because I need to send so many characters before my uC responded the speed is 2400 baud Thanks Putty screenshot : 77292
Hi, I have about 100 transmitter/receiver (Not transceiver) pairs transmitting at same frequency and i want to interface each Receiver to a pic micro controller. the transmitter is also connected to a pic micro controller and sending a unique code but the transmitter frequency is same, now the definite problem is the interference is there any way
It depends on the FPGA. many of them allow you to define an I/O as LVDS, but you need to have the proper I/O voltage. It's not a question of your transceiver being compatible, it's a question of your FPGA being compatible!
hi friends, i'm using max485 to transmit data serially. and i wanna send and receive data to more than 250 device. can i do with out repeater. i tried this with 3 device, so i didn't put any repeater. help me when you come to know about this.
Hi All, I am trying to interface two computers (wireless) using rs232(Null Modem). Wired connection works fine (Transfer of files working between two computers)!! But there are many issues with wireless transmission I am using TWS434A and RWS434A for RF transmission. I have connected the transmit pin of RS
Depending on type of communication, in many cases is a simple receiver enough if you have a antenna with high gain. For weather satellites can you buy cheap receiver kits which connects to PC sound-card. High antenna gain => narrow lobe => Tracking helps to keep contact a bit longer time. many LEO satellites communicate in a narrow band mode and is
hi there are many possible ways to do the same before that, which MCU you are using? ml
The CAN module is interfaced to the CAN bus using a transceiver. So it is the transceiver that matters. Decreasing the bit rate allows for longer network distance. 500m at 125kbits/s is possible. You would have to try out a system at 1000m and see what results you get. If you get too many errors, you could use a repeater half way down (...)
many basic blocks in simulink are supported for HDL conversion , else write an embedded code in an embedded block function
