Hi, If you have hands on expereince on MPC555 then please continue reading else ... I want to start experimenting with MPC 555. Can you recommend SW and HW tools for it? SW: * C (and C++) compiler with proper IDE (Integrated Development Environment) * SW libraries allowing me to perform 1-Wire, I2C, SPI, RS232 comm interfaces * RTOS (optional) * Matlab interface (hig...

Dear Frends, I am using mc35i gsm modem from siemens and want to connect that with my microcontroller, so for full modem configuration should I connect MAX232 to all the 9(nine pins of full modem) pins of controller or just Tx and Rx. thnx n reply Pankaj

Hello, I am looking for a software program mentioned in the topic of this message. I want to connect two PCs (one of them is running a developed embeded software talking to the outside world through RS232, while the second PC monitors the output from that first PC using null-modem). I googled this subject before, but it returns mostly shareware/trial/ demo programs. The freeware products I...

Hello everybody, I work for a small company that deals with automatic vending machines. I'm investigating the possibility of developing an embedded system to replace the actual controller. I realized a prototype using a nettop, netBSD and a USB to RS232 adapter. Now I'm looking for some kind of ARM platform, to use instead of the actual x86 machine, with the following requirments: -...

Hello embedded systems gurus ;) I have a general question about the PICF877. I was wondering if there is a way to interface it with mini USB through software, meaning i dont wanna have to buy a mini-USB to RS232 adapter. Thanks in advance -Tony

I am new to the FPGA and I want to learn by small experiments. Can some FPGA experts tell me what is the easiest and least expensive way of getting started ? What eventually I want to implement (what I'm dreaming) are; * Communicate with four RS232 devices (115200baud) simultaneously * Control 16 parallel I/O lines * Encode/decode multi channel Radio Control signals ...

hi all, i am using sbc6300x from embest, with linux 2.6-24, the kit has one com port for debug and 3 com ports for serial connection as ttyS1,ttyS2 and ttyS3. i can use ttyS3 for connecting to pc via Rs232 but unable to use other ports. any idea is appreciated for solving this problem. thnks --------------------------------------- Posted through http://www.EmbeddedRelated....

I am asking this here since you have probably met the problem. I have developped an embedded system that has a serial link (RS232) as user interface. So far we used a terminal to communicate but I now need to develop a gui application for windows 7. I have tried doing that with Excel with a commercial active X but I get an "acces denied" error when I open the port. I have also tried py...

Hi all, I have a logging product where the data is downloaded serially over an RS232 or ethernet connection. Typically multiple units are connected on the same network and polled regularly for data by the customer's system. Now it has come time for me to create such system to do the polling and data storage, but I'm not sure where to start. My thoughts are to install an SQL compa...

I'm attempting to interface a CMOS camera module [C328-7640] to my PC via the RS232 com1 port to learn how to interface with the chip. The modem cable is working ( I tested it by connecting the Tx & Rx pins (2& 3) then opened hyperterminal and when I type any letters they get written on the terminal ) I put both the schematic and how the breadboard is wired on my website to show what I d...

Hello, My goal is to get a distant access (using an Intranet connection) to a device connected to a Embedded Server through a RS232 serial Port. Now i use a HelloDevice 1300 by Sena Technologies, but I have some problems because sometimes the Embedded Server doesn't reply when contacted or it goes really slow. Is this a common problem with HD1300? Anyway the EES is not stable, at leas...

I want to set up a some automated testing of our product. I need to be able to: 1) Manipulate GPIO 2) Time edges (down to 100us) 3) Communicate via serial (SPI, RS232) 4) Set an analog trigger and record 500ms of data at > 100Hz Ideally this device (or devices) would have some sort of API so that I can write an application to control all of this. I'd really like to spend less than $800.

If anyone has this datasheet please email it to me. :) Siemens requires registration through a reseller to access the technical documents. I need it to confirm that the unit will work in our setup. Alternately if anyone could tell me how to power the damn thing... There is only an antenna connection, RS232 port, one 4-wire and one 6-wire phone sockets. Thanks Ross

Hello Folks, Looks like I'll have to debug code for a small uC (MSP430) in the field pretty soon. Cramped space, things can be banged around a bit, the usual. What would be a small, low cost and bare minimum laptop to do that with? Or is there a nice PDA where a keyboard can connect to? The programmers work via USB. The bootloader I may have to provide would be RS232 but that could b...

I=92m trying to get some PIC to PC communication going using the 16F688, but I am not having much luck. Hardware setup is just a PIC16F688 with power, and RC4/RC5 connected to an RS232 ShifterBoard Kit from Sparkfun. (http://www.sparkfun.com/ commerce/product_info.php?products_id=3D133) I grabbed the code below off the internet somewhere. Nothing hooked up to the ADC but that=92...

I am using a rs232 to wire rs485 converter. I have shorted TX+ with RX + and TX- with RX- for 2-wire configuuration. A 120R termination resistor is connected between TX+ and TX-. I am using it in half-duplex configuration. Is it possible to test loopback. Because in half-duplex either tx or rx will be enabled. I have not tried this. Just before trying want to check if this will work.

Hi I'm communicating to a HP33120a function generator. PC and instrument are both DTE devices and I use a null-modem cable as described by HP. When I run the software I have written in LabWindows I sometimes get errors from the instrument.
