I am in the early stages of learning Intel assembly coding, is there a free development tool available that I can use to test out an assembly program. Any other recommend sites or materials that I might use? Thanks

It is homework in the sense I'm writing up a lab on did on an active filter and I have to take into account the measurement error of the output. The spec was very vague to me, the Bode analyzer had an amplitude error of 12 bits. I just need a reasonable calculation to the error in reading the...

I've run an experiment on an active filter. I am using the NI Elvis prototyping board. The frequency response is taken with the NI Bode analyzer and I saved the output data in a text file. The Bode analyzer amplitude spec is give as 12 or 16 bits, how do I calculate the amplitude error using the...

Can you aim to one of the older free versions, thanks.

Thanks for your time and effort, but I have to use PSpice, it's for a class. I'll look around and see if one of the older version will do the job for me. Thanks again.

The SW is a demo version, best I can tell no time limited. It is crippled in terms of number parts that can be configured.

I'm running a Student version of Pspice locally. It was running okay.

I have a simple circuit 2v supply R and Diode in Pspice that I'm trying to run a simulation on. I get the following message. "This action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy program and correct the problem." I have no idea what the...

I only have available a 7410 Nand (I need 3 inputs) I was going to place a 7404 inverter (all I have available) on the output to get active high output. I would like the LED to light up when output is High. Circuits are a 2 to 4 and 3 to 8 decoder. How will the inverter change anything in...

To confuse matters, it turns out I need to have active high outputs. The 7408 is a nand gate I assume if I put an inverter on the output I will get an active high output. How will the inverter change anything in terms of driving the led's?

I am building a 2 to 4 decoder with 7408 And gates and need to put LED's on the output as indicators, active high. 2 questions 1. Would I put a current limiting resistor in series with the LED to ground or put the resistor and LED from the gate output to Vcc? 2. The LED draws 30mA at 2V...

Thanks, so in the instructions below the effective address is in the operand, correct? How do I determine the address and affect registers? I am suppose to determine the effective address and the contents of any affected register (except the PC) or memory location after each of these...

The latextlab site seems to be down any other suggestions for information. This is an assignment from the 1st chapter of a MC68hc12 book. It doesn't explain effective addressing, just uses the term. I'm totally lost. Thanks for your help.

I am suppose to determine the effective address if the instruction below and the contents of any affected register (except the PC) or memory location after each of the instructions in problem is executed. Assume the initial state (in hex) of the CPU and memory before every instruction is as...

Attached is what I did, I haven't rewritten yet. Sometimes ignorance is bliss, I hope I did it right.
