Well in order to answer the question one would need significantly more information. What springs to mind immediately is thing such as
- Embedded or Desktop target
- What OS, if any
- Degree to which logging is required (all actions/events only errors/exceptions)

32 bit hex conversion in to decimal
Ideally this is how I would break down the problem,
First make a assembly routine that correctly displays a digit given the appropriate number - such as 5 produces a '5' on the LCD
Convert the integer number to a hexadecimal value using assembly - search...
Re: LCD display
Assuming that the LCD is a character type and that you are programming in C simply use the spfrinf or fprintf constructs to convert the floating point number to a string.

sound card maximum input voltage
@echo47 would one not be able to do the reverse. Rather than determining the clipping voltage when applying an input voltage use an application such as winamp that allows software amplification. In this way the card's output would max out and you can verify the...
By petrol dispenser do you mean a petrol pump such as at a gas station? Also depending on the HMI the system might include an LCD, 7 segment, i-button, keypad, flow sensor, motor / pump, network connection, and an MCU. The control part would the entail the programming of the MCU to use the flow...
two-ray model taylor series
Why would you want to use a Taylor series to prove the transmission equation. However I suppose that you could simply do the math using trigonometric functions to account for the phase effects and use the standard decay for the amplitude.
By repeating the process...
Re: watts conversion???
Also the power requirements of a CPU is typically the maximum current that the chip can handle. As mentioned power requirements are a function of several factors not least being the resistance since heat affects resistance and resistance affects the current the power of...
I would suggest that you calculate the required speed difference between the wheels (this is the number of encoder samples) and use PWM to drive each motor independently. This will allow the vehicle to move in circular or any other arbitrary paths. By running both motors at the same speed for...
Re: suggest a technique to measure distance in inches using
Why is SONAR not an option? If I recall correctly the speed of sound is approx 300m/s at 100km/h the object is only moving at ~30m/s by measuring the doppler shift, you can calculate the time movement of the object. Alternatively using...
enc28j60 atmega32
How is address 0x15 defined. If it is a register within the ethernet IC you should send the desired register first and then read from the device. Typically SPI devices does not have an address and makes use of a chip select or enable to activate the device.

Yes, either use the extra RAM on the LCD to define custom characters or use external memory interfaced to the MCU to store the custom characters if you stay withing the (5x7) or (5x8) pixels per character you can display any pattern you like.

Re: My PIC program hangs
Normally the C compilers handle the bank switching stuff internally. However might it be that your code does not have a valid / correct return path since you mentioned that you have functions calling functions?

I dont understand the question do you want to make a wireless LCD screen using bluetooth and a MCU?
In that case simply go for a Bluetooth module that connects to the MCU via UART and connect the LCD screen as normal to the MCU.

ubuntu drawing software
Hi since you are running ubuntu I assume that you are using gnome. In that case try Dia, I have used it before and it is quite good (for my purposes anyway). It claims to be the open source equivalent of visio.
