Anyone know the quickest or easiest way of recording a serial data stream and timestamping each byte with a resolution of at least 1ms (preferably finer)? I can only find cheap or free programs with less resolution, or very expensive solutions, often involving special hardware. I only need to monitor one port, and I don't need to send any characters (actually I'm snooping on an RS485 bus). ...

I want to make a board that has: 1. ethernet socket 2. two rs232 ports 3. one rs485 ports And put an enclosure around it. Do you guys know of any enclosure companies that sell plastic enclosures that look like your small typical Netgear or Linksys hubs, which i can just get the holes cut out? I need that "cool" look, rather than just going to Digikey and getting a simple plastic rectangu...

Hi, I'm looking for an embedded board with these minimum caracteristics : - maximum size 150x150mm - low consumption : less than 1A with a 5-7V power supply - one (or more) i2C link - a free RTOS running on with free tools (to compile, download, ...) eCos would be the better. - one usable (not only for programming) RS232 link with a DB9 connector A do not need a powerfull CPU, ...

I'm building a small device that will talk to the world through a modem. I've ordered the XE2422H devkit from XEComm. It basically has a RJ-11 connector for the phone line and an RS232 connector for the controller. I need a cheap microcontroller that's easy to deal with which I can interface with the XE2422H. It will be doing data collection via the modem, so I'd like it to have at least 256KB ...

Hi, I'm new here ad new to PC 104. I have a PC104 system in front of me having: - RS232 port - MVB/CAN Bus interface - Parallel port - PS/2 keyboard port - special connector to a touchscreen which i have (working!) - some little rotary switch to dial in a address for something in hexadecimal (now it is 0xF and 0xF) - a loudspeaker output everything boots fine.

Hello all, I'm using the at89C51RD2 in an current application where I;m trying to use the Flip and the RS232 ISP programming. I programmed a virgin chip perfectly the first time and was amazed at how easy it was. Now that I'm trying to program it again though I'm having problems. The flip software is giving me an error message about a software timeout. I've done nothing with ALE I've...

I have some hardware that has a PIC18F6680 pic cpu. This is older hardware that is non programmable that we are starting to replace with a reprogrammable version. The newer version is the basically the same, but has a maxium max3233e rs232 chip, and a mini headphone jack that we connect to a laptop to program with vendor software via a laptop w/serial port. What would be the easiest way to re...

Hi everyone I'm upgrading an existing embedded system. This system has 1 serial port and DOS is runnig on it. But customers wanted this device to talk with other 8 devices over RS232(new requirement) First idea i came up with is ; finding a new card with 8 serial ports on it and integrate it to the former system.So that it would be the interface between existing system and other devices. ...

Hi folks, I need some advice: For my diploma thesis, I need an embedded PC with CAN, RS232, Ethernet, RT OS and low power consumption (for use with battery). Finally, I found a system, that would fit best, but the problem is, that it just includes standard linux support. (it=B4s an embedded pc system from janz, with NS Geode GX1, 300MHz, http://www.janz.de/as/files/empcx302.pdf ) An...

Gang: Now that all the cuel new laptops have no serial ports and no PCMCIA card slot, and I am stuck haplessly with USB, does anyone have a good experience with any USB (or fire-wire) serial devices? I have many legacy apps that want to talk to a UART real bad and the quality of the driver would be the issue here. I would really appreciate a couple of names of devices I could purchase...

Could someone recommend a gps module suitable for use in embedded projects (pic and lpc21xx) , robotics and hooking up to a (laptop/pc with windows and osx drivers). Either 3V or 5V powered, ASCI output via rs232 or i2c or spi - (NMEA 0183) and under 10cm by 10cm (5cm by 5cm or under would be better). Start up time isn't a concern , up to a couple of minutes is fine Quite a few out th...

I have built a number of battery operated circuits using PIC16F88s. They are housed in a plastic case with a socket to plug in a serial connection for controlling LED outputs by RS232 comms. Sometimes when you touch the socket with your finger, the PIC responds in a manner suggesting that it has received some random data on the Rx pin of the USART. The problem occurs much more frequently ...

Hi c.a.e, I was asked to implement a bidirectional communication via USB (on an AVR32, which is OTG capable) between two identical devices. After some time of searching I couldn't even come up with a definitive answer if this is possible at all. Effectively this connection should work like a RS232, i.e. when you connect the two devices with a cable they should start talking to each other wi...

Hi! I am a newbee of using PIC USART and internal clock. I am developing a program that will send a data to an instrument to enable it to send an output to the PC via RS232. The problem is, my hardware has 8 channels with different instruments which run with different baudrates. The data sent is similar on all channels. How could i send the correct data to the corresponding channel which i...

Hi All, Any suggestions about making high-speed (16k baud) opto-isolated UART communications between 1. Microcoltroller to Microcontroller at TTL Levels. 2. RS232 port and microcontroller How do you guys do it. I use two opto couplers (4n35) for receive and transmit side but it has its speed limitations. Thanks, Rohan

Hi, I'm new here. I'm italian and so my english is not very good...pardon! I have need to program MSP430F2121 (28 pin, 4KB, UART) using BSL (Bootstrap Loader) controlled by PC. By Visual Basic 6, I'm be able to driver RS232 (TX, RX, RTS, and DTR) and I'm be able to communicate to MSP430F2121. I make thing step-by-step, reading before sall0089d and slaa0096d.

I've got an application that needs an SBC (a redundant pair, actualy) which will survive 24 hours on battery power. I either spec a bank of big batteries, or find something less hungry than the 12-watt Ampro board I was originally looking at. I need Ethernet, 4 RS232 ports, USB, and 512MB of DRAM. I did some searching for Alchemy or XScale SBCs, but everything strikes out on the memory ...

Hello everyone, I'm working on a project that requires sending pixel data from an fpga to a PC, RS232 would be fine but Ethernet is also considered. (need to create a bit file to process the image in the PC). Any VHDL code reference for the transmission process and any advice on generating the bit file would be highly appreciated. Thanks,

I am trying to make it work under win8... It isn't a Prolific 2303 and it isn't an FTDI FT232 or similar... Win8 does notice it was plugged in (it beeps) but nothing new (that I can see) appears under Control Panel / Devices. I would expect a COM port with a Hayes compatible modem behind it. That is what their older models do. The old 7100 is a straight RS232 Hayes modem, but the XT is...

Hi all, In serial communication, eg. RS232 or RS422, we can configure the port (for example) to send 8 data bits, Even parity bit and 1 stop bit. However, when the receiver receives, it only reads in the code and output to the screen. How can I capture the parity bit that is sent? Thank you for your advice. FT
