Is it possible to program over rs232(first time) on a AVR Development Board for Atmel
I just got this board :
I have not got a jtag cable jet, so i was wonder if there is any chance that i can use rs 232? Just use (data send, data recive and ground)

Hello everyone, I need helps with connecting the microcontroller to my laptop. I've just ordered an ATMEL AVR Mega128 ATMEGA128 development board and it is on the way to my home. I wanted to connect the development board to my laptop through the usb cable. At the moment i've got a USB to RS232 Serial 9Pin MALE Cable Adapter which i think i can plug in the usb cable to the laptop side and the RS232 male plug into the development board which has the RS232 serial port as well. The development board i've ordered is this: http://cgi.ebay.com.au/ws/eBayISAPI....=STRK:MEWAX:IT And the USB to RS232 adapter ...Hi My name is Yehonatan and I am new in the AVR field recently I began to build development board for atmega162 but than I found a problem how to connect my avr to the JTAG because some people connect the AVR to the JTAG witout resistors and some like atmel connect the JTAG with resistor to load now I have 2 questions 1.what is the best way to connect the board to the JTAG 2.if should I use resitor to where I should connect them and what is should be thier value http://www.atmel.com/dyn/resources/prod ...

Now, I use a cable of RS232 connect between PC and a infrared board. If I key in some characters from the program in PC, the data would transmit through the cable of RS232 and send out by the infrared board. In the other side, I use MSP430FG4618 connects with a infrared board by a RS232 cable. I use a code in Code Examples, wishing to achieve the effect of ...I have the Ethernet development board from CCS and I am just powering it up and reading the exercise book for the first time. I want the device to act like a HTTP client. I want the dev board to send HTTP requests to my webserver on the internet. I want it to send data, like analog1, along with the HTTP request. Ex Code: http://www.website.com?val1=2333;val2=444 Is this possible with the ENC28J60 and 18F4620 development board? I want to get this data to my website for later retrieval. I could also use FTP if the Dev board can send data to ...Does anyone know of an ARM development board with at least 4 RS232 ports? I have a need to combine multiple RS232 input data streams into one RS232 output data stream (currently it will be 3 inputs to 1 output). So assume I will need a minimum of 4 RS232 ports. Development time is relatively short - about a month (including hardware integration time) - so I need a solution that's already available. Thanks! -Matthello to all i try to build project with ethernet to recive data from rs232 and send it to socket server on the internet and receive the answer from the socketserver with internet ans send the answer to the rs232 naw i can recive and send using rs232 with uart but i try to build internet socket with eathernet i cannot any help haw to make socket server with eathernet click board thanks for allHi, I've done a bit of Arduino work in the past... I need a very small Arduino board for a project, and this caught my eye: http://www.ebay.com/itm/AT90usb162-USB-Atmel-AVR-Arduino-compatible-development-board-DIL32-bootloader-/130588257809?pt=LH_DefaultDomain_0ampvar=amphash=item1e67aaae11#ht_5417wt_1297 I'm a little confused by how it just says "Arduino-compatible". Would it work as expected for simple sketches to receive serial data (MIDI) from my computer by USB, and turn some LEDs on and off, without any extra hassle? Or, would something like this, with an ATmega328, be better? http://www.ebay.com/itm/Nano-V3-0-AVR-ATmega328-P-AU-Moudle-Board-Mini-USB-Cable-FOR-Arduino-s-IDE-/180924940223?pt=LH_DefaultDomain_0amphash=item2a1ff77fbf#ht_691wt_1063 Thanks a lot for looking - I'm sure the answer is very simple, I'm just not quite experienced enough to be able to know for myself.I am using AT90CAN128 for one of my custom board and the board doesn't have any user interface. It is interfaced to control board (via RS232) that has GUI. I am little bit confused on how to put the Atmel RS232 bootloader image when the chip comes out of manufacturing(Atmel). Should I use JTAG or ISP for first time flash or can I use the bootloader at very first time. If so how does the UART know whether its application code that I am trying to download. Can please somebody explain how this would work as it seems very sketchy ...Hi, I've designed a simple circuit, micro and JTAG interface on a PCB, clone of S-EK Atmel board. Testing the board with 7S64, JTAG seems different, after 1st programming attempt it fails to program but micro stalled, then a manual reset via jumper thats connected to JTAG (pin15 rst) will then allow program to be written to flash. My program runs fine on ATMEL board (7S256), not a size issue to drop down to 7S64. But... Biggest problem, I'm getting spurious interrupts like data abort and fetch abort at various locations that don't seem to repeat in any order. I've ...I have an Atom Pro 24 that I have programmed through the IDE interface and the Atom Pro development board. It blinks a few lights. I've tried to replace the serial cable connection with a Connectblue bluetooth RS232 serial port adapter. The PC uses bluetooth and a virtual serial port to commuicate with the Connectblue RS232 adapter. The adapter (DTE devices) is is then connected to the Atom Pro development board (DCE device) with a straight through RS232 cable. The communication link between the PC and the adapter appears to be good; however, when I plug the RS232 cable between the serial ...The ATMEGA128RF is an awesome little chip with integrated wireless. It retails for $10, however the development boards cost over $50. If I got a $18 development board for the simpler ATMEGA128 like this one from ebay: http://www.ebay.com/itm/ATMEL-ATMega128 ... 1c2b1adbf9 what would it take to "drop in" an ATMEGA128RF? I know it would require some surface-mount (de)soldering and a small antenna, but are there significant other considerations that would make this transplant more trouble than it's worth?I believe the Dragon could be connected to an Atmel XPlain board using a 10-Pin JTAG cable, (JTAG Header to JTAG Header). (This is not what I want to do right now...). I would like to try using the Dragon's PDI capabilities to program either an XPlain board, or my own XMega PCB. I am looking for a reference showing how one connects a programming cable to the Dragon for PDI programming. The AVR On-Line Studio Help to Dragon manual shows the Dragon's JTAG and ISP headers, but does not state the PDI Clock and Data connections for PDI usage. ...Hi, i want to program an ATmega128 via jtag. i have read that it is possible with avr studio and ice5 (in circuit emulator). my question: which tools can program the controller with a simple jtag cable (i have a jtag cable from a xilinx development board)? or do i need the ice5 device? thanks in advance. greetings, hqqhI want to use this device, but can't get it to work with avr studio: http://www.olimex.com/dev/pdf/avr-usb-jtag.pdf last week i bought an avr-jtag-usb. I connected it with the flat cable to my development breadboard with an Atmel Mega162 on it. My board is powered with 5V, and with the same flat cable I can use a borrowed AVR Dragon to read and program and debug the application in the mega162. I have a working flashing led application When i disconnect the dragon, and install the avr-jtag-usb, and apply the 5volt again my blink led application starts working, and the red light ...Time for spring (summer) cleaning... I listed a few items on Ebay that might of interest to the regular readers of this newsgroup.... (Too bad Ebay wasn't around when I started my company so many years ago.) Don't worry, I'm not going to pull that hokey "I saw this listed on Ebay" stuff, and (fortunately) I don't need to hock my skills/services on Ebay. Just figured some of this stuff could be put to better use in someone's hands than idle on a lab bench.

I need the board to have DB9 connectors for RS232 communication as well,since it accelerates prototyping. I previously bought STK128 from ebay, but I've got problem with programming the chip and I'm suspicious that the board is defected. So I welcome any recommendation from you guys (if you worked with a board previously and you're satisfied with it) Many Thanks SonnetHey guys. For some reason, I'm not receiving data (through Hyperterminal on my PC) I should be getting from the RS232 SPARE port on my STK500. This is what I'm doing: So I wrote a little program on my ATMEGA48 to try and send data over UART. I connect my PC to the RS232 CTRL port on the STK500, and program my chip with the code found here: http://www.quickid.net/c_code.txt. I also have connected the RS232 SPARE 2 pin jumper to PD0 and PD1 (RXD --gt PD0, TXD --gt PD1). Then I turn off the board and move the RS232 cable ...Hi TI.

This lead me to do some digging on rcgroups to see if there is a way to make one myself without having to wait another 5 weeks for the original one to be delivered. From what I understood the Hk cable is nothing more than a 5v TTL usb to serial converter gt MiniDIN 4-pin male connector. This means that any such cable, correctly wired, should do the trick: Pin 1 : PMM signal Pin 2 : +5 Volt Pin 3 : ...
