Hello all. I have been thinking about a next project to do and I think I know but am a little lost on how to do it. I want to take a bunch of normally open buttons and connect them to the picaxe. I would then continuously poll these buttons for their status. But, I want to send the button...

Hey all, I was going through my bin of electronic parts and am going to sell some stuff on ebay. However, I figured before I go on and sell on there, I would let everyone here have first dibs. All prices in US dollars. First come first serve! Here is what I got: Deleted Please see sentence 2...

Like this? Edit: Ignore the thumbnail, it was clearly wrong. I don't know how to turn it off :(

Hello all, So I have been using a small piezo buzzer I found a long time ago from a basic stamp II kit (http://www.parallax.com/StoreSearchResults/tabid/768/List/0/SortField/4/ProductID/106/Default.aspx?txtSearch=piezo+speaker). It works fine and the tune command works well with it. However, I...

http://www.mouser.com/ProductDetail/Lumex/LCD-S301C31TR/?qs=MaxZGLOdHCklXRbbadKoXSKVG%252b8yEKUzlh6zKiw7rzo%3d So I looked on the datasheet and it says that the forward voltage is 5VAC. I even contacted the company and the engineer said that it is indeed AC. Now I know that I am only an...

Also here is the schematic.

Can the tune command be used in parallel tasking? For example, have start0 contain one set of notes and start1 have another. Have both legs that output the tune connect to the piezo speaker but through a diode to prevent them from feeding into each other. Or make it less complicated and use two...

Hello all again, I have come to the point in my project that I need to monitor time elapsed in the background. I know the M2 chips have a internal variable called 'time' and increments every second. But I am using a 20X2... so what are my options without additional hardware?

Hey all again, I am now at the point with my project that I need to write some basic "alarm clock functions". I would like to use the NES controller to increment hour and minutes. My plan was just to simply save a combination of bits (certain button presses), read this combination against...

Hello all, So I posted a program a while ago that showed the buttons statuses in a NES controller. I am now trying to switch this code over to a 20X2 (was working on an 08M2 before). There are two problems I am having. First is that when I try switching from the shiftin sub routine to the...

Hello all, I have a new project I am working on and hit a snag. I am in the process of making an alarm clock out of an NES controller. I am using four seven segment displays (multiplexed) to show time obtained from DS1307 RTC. For now, I am just trying to display time on the seven segment...

On the first manual, page 18, it says that the X2 parts default to 8MHz speed. Can I still technically run it at 4MHz if I really wanted it to with the setfreq m4 command? Or I cannot go lower than 8MHz operation?

So if any of you guys read the thread I recently made here --> http://www.picaxeforum.co.uk/showthread.php?20787-linear-function-with-decimals&p=199690&posted=1#post199690 I said that I used Select...Case to make a sort of table to acquire a value 0-99. Now the reason why I didn't go beyond was...

Hello all! So, the question is can I express the function f(x) = 0.0206x + 0.2867? I have been trying to think of a way of doing it but I do not think it is easy, or even possible with decent accuracy. The domain of x belongs to the set {0,1,2,3,....6000}. The range belongs to the set...

Hey guys. I am trying to get a 08m2 talking to an NES controller. I know it has the 4021 inside so it should be simple. However, I am not getting the expected data from the controller. The serial terminal keeps telling me that the "A" button is pushed but it is not. I double checked my...

Hello I am a bit stuck. I am trying to simulate a circuit for a friend that is taking an electronics class to show the concept better. Here is the question http://web.njit.edu/~levkov/classes_files/ECE271/test_samples.html , it is problem 3 under test 1. I am trying to simulate part A. I did...

Hello all I am trying to use the shift register within vsm. I have used one model but it did not have a pin for the shifted out bits. I am now using the shiftreg_4 primitive. What I am trying to find is the pin explanation for this model. What is DL, DU, QU, and QL? I want to use it as a serial...

Hello all I have been trying make this line of code work within my program but VSM seems to have a problem running it. serin [300],5,7,b0 When I try to run this code by itself outside of my program (meaning what is above is the only thing I am trying to simulate) the 28X1 in VSM will give the...

Hello all. I seem to be having a problem with downloading a program onto the picaxe chip. It is a 08M. I have an axe027 usb cable. I am able to successfully download the program from my desktop but have a problem with my laptop recently. When I test the serial in port on the desktop, the...

Hello everyone I am trying to retrieve data bits from a shift register. Actually, it is a shift register inside the Super Nintendo Controller. Here is the info regarding its function http://english.cxem.net/pinout/pinout21.php . I am using the PICAXE 08M. When I read the manual, it stated...
