Programming micro-controller using serial port

[nitincool01]

Hi,


I am new to field of Hardware, so i have some doubts..

I want to know, is it possible to download Hex files to micro-controller using serial port with some serial communication utilities like flash magic or Flip.

I have connected TxD and Rxd pins of micro-controller to RS232 level converter and from the level converter i have connected serial connector..

Hoping for help.

Thanks,
Nitin

Hi Nandhu,

Greetings !
Thanks for your co-operation.

Am using atmel 89c51.

 

[nandhu015]

at89c51 cant be programmed with serial port.

at89c51 cant be programmed with serial port.

So please can u let me know any microcontrollers which can be programmed using serial port....

Thanks,

can u let me know any microcontrollers which can be programmed using serial port....

AVRs can be programmed via bootloader:

Atmel Corporation - Atmel AVR 8- and 32-bit Microcontrollers
**broken link removed**

Hope that helped,

if you want to use 8051 core that can be programmed serially, you can try STC12C5AXXXX.
STC Microcontroller-The world's largest 8051 MCU family

please dont mind, i have one more simple question..

does these AVRs ship with bootloader programmed.. if not can u let me know how to do it..


Coz i dont have any hardware programmer with me.

thanks,

AVRs don't have any bootloader, so have to write bootloader by yourself. Please take a look at the link i posted before. or you can make a very simple ISP cable from AEC, download the program and you will see the schematic. It doesn't use any chip www.aec-electronics.co.nz. Because that software doesn't support AVRs, use SPIProg, ISP Programmer | Adam's Site, and configure it as AEC, and now you can download your bootloader.

P89v51rd2, At89s51/52, avr's All can be programmed serially (or using mosi miso sclk pins... with the help of small adaptor used with db9).. Most easy to program is p89v51rd2
