In some compillers (i.e in IAR compiller for avr) are intrinsic functions for generate acurate delay. In IAR this is function:
Try to look at the manual of your compiller, maybe it has similar function...

Please look at PROTEUS software in sample files.
In samples have calculator by using 8051 PIC and avr, but no scientific calculator. You can modify it.

I know that the MCS-51 family is not particularly suited for math operations.
You should go for some higher end controllers.

There is no code needed all is done using fuses setting during programming,
You can calculate the fuses needed for the crystal with this online calculator (or the datasheet of course)

Nowadays, most computers are not equipped with RS232 or LPT port. That is why this programmer was designed. The project was taken from: LINK and modified a little. The board was re-designed.

It resembles I2C but is can be using a custom protocol, you can find many articles that explain the I2C protocol using google.
I have only used I2C from avr a few times so I can't give you much details on the protocol.

You should use 4.3v since the voltage of the pin will be at that level when you have the led consuming 30mA.
30mA is kind of high for a led, it is usually 10-15mA but the avr can provide the current if this is what you want so there is no problem.
Note that the chip max current is 300mA so I hope you don't intend to drive many leds.

Your capacitor value is high, the recommended values are 12-22pF
CKSEL3,2,1,0 = 1
You can only disable the JTAG fuse from the programmer, not your C code

By the way , delay.h has a few functions based on delay_basic.h so delay_basic.h is already included when you include delay.h,

You can use this calculator
You have currently set your mcu to external clock so you need to connect an external clock source in the XTAL1 pin to reprogram it.
You can use another avr set to toggle a pin on/off as a clock or a crystal oscillator or even a 555 should do.

I've been using the GNU toolchain for avr programming, including the avrdude utility to flash the MCUs and set the fuses. A few months ago I started thinking if I could eliminate the command prompt from my workflow entirely, because I was mainly just running the same few commands again and again to upload .hex files and set fuses.
Microcontrollers :: 14.08.2012 15:44 :: jokkebk :: Replies: 0 :: Views: 152
The fuse bits available in each mcu model are described in the datasheet in the memory programming section.
The main fuses you need to set are usually the ones related to the clock source selection.
If you want to use the jtag pins as I/O then you need to disable JTAGEN.
Don't change SPIEN because it can disable the serial programming.

Yes it uses an external 16MHz crystal.

If you want to execute something periodically, place that in timer interrupt.
If you are using PIC dsPIC, PIC32, avr micro-controllers then use this tool to generate code and try to match it with your setup
