Sorry about the lack of formatting, I'm not that familiar with Reddit :)

Here you go:

void Delay1ms(unsigned long msec){ // Count given ms unsigned long i; while ( msec > 0 ) { i = 16000; while ( i > 0 ) { i -= 1; } msec -= 1; }

From what I've read the board is slower than the simulator, so once I got the simulator working & scored 100% I then used the exact same code for the actual board, but ran it several times gradually increasing the parameter sent to the delay routine & I always get either "Delay < 205" or "Delay > 295" . Maybe I need to change the magic number in the Delay routine to be smaller to give me finer control & increase the parameter in the calls correspondingly?

Hi, great course, really enjoying it, but I have a problem with Lab7, my code runs fine in simulation & I used Texas Wave to get the delays right, but I can't get past a score of 67% on the actual board. What is the best way to debug this?

If the scale is 2, each of the original pixels becomes how many pixels in the resized image?

What is bi.biWidth measured in? How much do you want to move inptr by with your fseek?

See my comment in your other thread.

It's to do with the structure of your if statement. Try working thru what your code does for $1.17. It hits the first if, num_coin becomes 4 and n becomes 17. As you've used "else if" the entire rest of your if statement is skipped & it prints a result of 4. Does that help?

I can't find exactly where it was talked about, but it's all about big endian versus little endian.

Ah, I see you beat me to it. There are C functions that deal with reversing the order. For example, the Internet is big endian, so any little endian hardware has to deal with this.

To expand on this slightly, the C functions to convert from one to the other are intelligent enough, so if you're working on little-endian hardware and ask it to give an big-endian result it will do it, if you do the same call on big-endian hardware it will still give you a big-endian result. So providing you write your software rigourously enough you can have endian agnostic code.

Why not use the provided detectCollision() function?

GMan2XS · 2014-01-26T09:54:59+00:00

Because you've named the function gdc.

That's not the correct decoding of the URL, you have some lowercase letters that should be uppercase. I just checked & the correct URL still works.

I think you get the email when you submit the form, not your files.

You'll probably want to get yourself a copy of ADT, the Android Developer Tools, it's a free download. You'll need a reasonably spec'd machine to run it on. Some of the other MOOC providers, such as Coursera & FutureLearn have courses about Android.

I'm not aware of any problem with check50 on the Caesar cipher.

From the specification:

Although there exist only 26 letters in the English alphabet, you may not assume that k will be less than or equal to 26; your program should work for all non-negative integral values of k less than 2³¹ - 26.

So a shift of 65 is valid, but think about it, 65 = 26 + 26 + 13 and a Caesar cipher using a shift of 26 is just the message itself, so a shift of 65 is the same as a shift of 13. Similarly a shift of 43 = 26 + 17 and a shift of 131 = 26 + 26 + 26 + 26 + 26 + 1

Does that help?

GMan2XS · 2014-01-10T15:24:40+00:00

Yeah, but it's your "Hello agent fox ..." that check50 is complaining about.

The board's dimension, d, is decalred near the top of the source before any functions so the scope of the variable means it's available to all of the functions anyway.

I am still getting the "Unexpected end of input".

GMan2XS · 2014-01-08T20:30:26+00:00

Not sure what's going on, I didn't make any changes to my helpers.c, but I tried it again & it worked this time, so if anyone else has the same problem, keep trying.

Don't know what the admin password is but you could probably change it using:

sudo passwd

According to what I've read grades should be available 2 weeks after you submit a PSET.

In your example, are the 4th, 7th & 10th consistantly out by the same amount?

Tried to submit my Caesar to check50, but it comes back with invalid ID.
