Hi,
I need to use µcontroller with USB driver and USART embedded in it.
I already found "AT90USB646" but I didn't find this devices in CodeVision or IAR.
How can I use it? or Is there any other device has USB and UART(AVR prefered)
..
BR.
Help me fix C code error - "the function is incomputable with its declaration."
Dear All, Alsalam Alykom,
I wrote this program and it didn't work, and i think it was written well so plz help me in.
this the function decleration
void PutString ( const char * Ptr);
and I called it by...
Dear All,
I use ATMEGA162 in my project I already use the 2 USART interface embedded into the ATMega162.
Now i need to use another USART by using the ordinary GIOs ports, so i need to made it by software.
Plz help me with accurate S/W for serial interface using ordinary ports.
I use ATMega162 for my project, and I need to deal with external device deal with USB interface, How can I use AVR's UART to deal with the USB?
OR what's the alternative solution?
Salam.
Re: Win AVR
Could you plz help me in download the hex and eeprom file to the ATmega162 using the parallel port,
What's the program i can use and how can i use it?
Dear All,
I'm trying to use WinAVR instead of Code Vision, so I'm trying to make code conversion.
I need any document about "How to use Interrupt, Port.pin definition, flash and eeprom accessing, or if you can help me in it.
Peace upon u,
I need to use LCD(graphical) to can draw my country chara. language and any other symbol 1.5x3 cm its Dim.. I want to get its part No. and datasheet (hint:low price one) to use it with ucontroller.
if u have (ISIS)PROTEUS 6 u'll find complete project of 8051 with keyboard and LCD and hex file included for this simple calculator.if u don't have PROTEUS u can download demo version from
http://labcenter.co.uk and see it.
Re: Size of Hex File
peace,
most of hex file generated if you open it by notepad you'll find in the left columns the addresses and then 32 hex No. which indicate date placed
you can see it and find where is the last data written befor filling the rest of ROM by FF or 00
like that...

salam,
I know what you mean you need to make MCU as computer have RS232 port so you need IC as "max232" to convert from TTL levels to RS levels then connect it dirctly to RS plug, you will have now serial port as computer, {if you download data sheet of this IC you can find...
