circuit of atmel 8052 programmer
you can build your own programmer using parallel port and a simple program.I did it.Here's a simple prograsmmer for AT89C2051,which u can change it for your own purpose.
U can use RS232 serial port because your data rate is not so high and u can send data with a 19200 baud.for this purpose I have a VC++ example which u can use in free.
goto
www.programmersheaven.com
and search for "TxRxCommunication"
you can use the program or use the source code fr your own...
I have a sample code,named TxRx in VC++ which has almost all options of serial port.You can follow the same functions of API in your VB program.For that source code go to
www.programmersheaven.com
and search for "TxRxCoomunication".
Hope it useful
Regards
Here's a free driver whch you can use in NT base Windows.It has some example too and I used it in VC++,but when you loadits DLL you can use the same functions in VB.It's some slow specially when you want to read parallel port but it works and this is important!!!
With million Thanks to Yarin...
Re: Flash Disk Designing
Maybe you can use a MMC(Multi Media Card) and AT89C51SND1 uController which has MMC built in implementation.So you can change you card too and change the capacity of your flash disk.If this is anew topic for you,maybe you have to read some documentations about FAT16...
A very nice example you can find on www.lvr.com from John Axelson.She has this example in her book "USB Complete",a very good course in USB implementation.
It includes both VB and VC++.
top programmer 2007 driver
you can fine some excelent firmwares and programs (in VB and VC++) in "USB Complete" book from John Axelson.She has developed a good example for a HID device which includes both sides,PC and USB device.The program for PC includes some API functions which you can use...
how to connect a webcam to microcontroller
There are some OTG(USB On The Go) like Atmel AT43USB370 which you can use as USB Host too.You can find the USB specification for Still Image Capture Device
on www.usb.org too.If you don't have any experience in usb firmware programming,(maybe)you have...
transistors based phillips 89 isp progrmmer
I have a hand_made programmer for At89C51,AT89C52,AT89C55 using 3 74373 Latches and 1 74244 buffer,some transistors and diods,caps and resistors.Using parallel port and a program in Win XP,2000 I can write any binary file on the device.It's not...
