Re: Need For Speed Shift Registration Code
Nichelle Gruger
Hello, I have bought NFS SHIFT from ORIGIN and I have activated it on my profile (EA Nation). To enter I write my email address which I used in my ORIGIN profile, but it is written 'registration code is already registered in the system'. Please, help me with this problem.
I hope one admin from Ea can help me all aready done all the other things that i could o on the game and its really pissing me off this, i already played this leagues i from nothing the all became blocked
Need for speed shift. after installing this game on my new pc it said:- The license limit has been reached. why the games is mine so why am i being blocked it is one of my favirate games and have put it on my last pc without any probs
I have a shift register array already in place. My issue is that most forums talk of HSC as the goto encoder input to prevent encoder input losses but in my case i need the actual pulse to shift the register. The HSC function is a counter, and converting counter readings to pulses would probably increase cycle times and eventually lead to loss of pulses.
3.1) Detect the relative displacement of the pulse counter at each PLC scan cycle and shifted by that amount. For example, if your figure is correct, you have an encoder pulse every 8 s, and in fact the PLC which is still much faster will see all the increments of a single unit.
3.2) If, on the other hand, you wanted to trace and react with the PLC program to individual increments of encoder pulses that were to have a higher frequency, on the order of a period of a few milliseconds, you would have to change CPUs and depending on the program to be put in place, write it into the relative interrupt OB.
If the numerical data you have written is correct, you are far from needing any special speed for now: 8 s is a very high time, where a PLC even of the 1200 series sustains brilliantly if you do not fill it opulent code.
Just a correction, its 122 pulses per sec which is 8 milliseconds between pulses. But you are right, I just wrote a program to detect relative displacement and shift the register. Its working well and the longest cycle time is 6ms. I don't know if this confirms I won't be losing pulses. I will later check repeatability during production to confirm if the rejection unit will always be on point.
Shifting bits without actually shifting bits sounds very strange - right? Assume you have an array of 2000 bits [0..1999] where 1200 bits represents the conveyor length from start (inspection) to end (rejector). There are two pointers: (a) write pointer beginning at index 1200 and (b) read pointer beginning at index 0.
I'm trying to use a mechanical 2 channel rotary encoder as a user interface device. I had one of the switches connected to interrupt 0 with the input pullup turned on, and the other one connected to pin 3, which is set up as a regular input pullup (without the interrupt). Pin 3 is read within the interrupt function, using an "if-else" statement to decide whether to increase or decrease the counting variable.
Up until recently, I had it set up with one button to select stuff, but the project in question (an alarm clock using a character LCD) will need more I/O pins than the ATMEGA328P itself has. I figured shift registers would do the trick. So, I set up the "supporting code" for an input shift register in a separate function that is called at the beginning of the main loop. Now, the interrupt service routine still gets triggered, but it never seems to read the second switch on the encoder as it should within the interrupt function. As a result, I can only turn the knob in one direction.
Since I did do quite a bit of rewiring, I checked the wires to the encoder as well as it's ground connections. Then, to rule out the relatively small chance of the ATmega328 itself being broken, I connected the wire for the second switch directly to ground and spun the knob with only the first one connected. Then, it turned only in one direction, but opposite of what it was doing before, so this proved that both the software and the hardware were still able to read pin 3-but maybe not reliably enough to catch a momentary pulse...
I did comment out the shift register function to ensure that the encoder, itself, was still working properly (Hardware and software wise, since I had to mess with both to add the shift register) Without the shift register code, the encoder works as it should, reading rotation in either direction.
Although I have things in my shift register code that I don't have elsewhere (A few For loops and bitRead() and bitWrite() ) I've read the references to those functions and see nothing that suggests that they will interfere with interrupts.
At this point, I'm lost. All I know is that it must be some kind of software issue because commenting out the shift register code makes the encoder work again. If the encoder didn't use an interrupt, I would suspect that my code was "too long" for the processor to catch the encoder pulses...
If you are short of pins because of your LCD, I'd recommend getting one of the adapters so you can communicate with your LCD over I2C, using many fewer pins, and then you will be able to connect your encoder properly.
Nw_ShiftRegClock is the one that is having the problem with the encoder only reading in one direction. It includes the shift
register code. The shift register must be somehow related because when I comment out the call to the shift register read
function, the knob works fine.
I don't have the actual LCD programmed in yet, but I was planning ahead with the shift register so that I wouldn't have to program multiple things in at once. (The shift register and the LCD) In other words, I was planning on adding the LCD when I was certain that everything else was working as expected. The way I am viewing the results of the program at the moment is via Serial.print()
Just wondering, is your encoder 4 pin or 6 pin package. If it is 6 pin, I read somewhere that some people got success on working them correctly by putting pull up and pull down resistors and some resistors on the LED pins itself.
Since my project doesn't really NEED an encoder, I decided instead to use Up and Down keys along with "Enter" and "Cancel" buttons. The reason I originally wanted a knob was so that I could move quickly by spinning the knob fast, and get right on the money by turning it slow (in other words, a pseudo-analog type of control). But, I discovered I could do that by having the incrementing of the minutes speed up the longer the button is held.
In a nutshell, the ATtiny would count pulses from the encoder, hold the "Forward" or "backward" pin HIGH until it gets an ACK from the ATmega, then it would subtract a count and momentarily turn off the direction pin, then turn it back on when the ACK input goes low.
This would prevent timing issues with the ATmega from interfering with the encoder process, as well as negating the need for interrupts (Not that they're necessarily bad, but there's quite a few specific things to keep track of that newcomers might find daunting. As I said, I did get it to work, but it quit when I added on to my program).
However, if you're reading an encoder for feedback purposes rather than a user interface (i.e. some kind of automated machine with precise positioning needs) you'd probably need either a faster processor, more efficient code, or both. One could also have a separate MCU for reading the encoder(s) and controlling the appropriate motor(s), which would simply listen for commands from the main computer.
Hello, I have recently purchased the CY8CKIT-044 PSoC 4 M-Series Pioneer Kit and having a great time learning how to do simple projects. I am trying to write a simple program to interface with a 74HC595 Shift Register to control 8 LEDS. The HC595 has a Clock input, a Serial Data Input and a Latch. I am trying to use the Shift Register in the PSoc Creater and need some help with the top schematic. I have uploaded my top schematic for review. I want to know how I can create a bursted clock that will be used to clock in the data the the HC595. I have tried to use the Clock component from the SYSTEM group and connect it to a Digital Output pin but it won't compile. If anyone could give me some suggestions of know of an example that uses an Shift Register please let me know.
You didn't describe the project and its goal. But you can control a lot of LEDs with minimum number of pins by Charlieplexing. This method lets you use only N output pins to control (N*N)-N output LEDs. Google it.
Hello and thanks everyone for responding to my post. I've been doing some Arduino experiments with my daughter and in the last experiment we used an 74HC595 to control 8 LEDs. It was pretty easy, mainly because there's books that describe how to code the little processor. So every week we do a lab and I'm trying to do the same lab experiment on the CY8CKIT-044. I found the Shift Register in the list of components and thought it would be easy but I hit a few roadblocks mainly on the wiring. I know how to control the latch and the serial data will be from the shift register but I ned to get a bursted clock working. I thought I could use an AND gate with a clock input and an enable from the main.c program that would gate the clock on and off. But first I need to get a Clock connected to an output pin. Thanks for the examples. I'll try to get things working. Its fun stuff and a way for me to learn a new processor.
In a more realistic scenario, we need the output from the last iteration. In this case, the difference is even bigger. Notice that the feedback solution does not have an output similar to wiring from the right shft register and we need to create an output tunnel with indexing disabled.
