Could someone please explain how to work with floating point numbers on Amulet. Could they be stored in internal ram? How to use them in further calculations?...
The floating point capability of the printf parameter is usually for display purposes only. Any math you do on InternalRAM variables is treated as integers. If...
I'm trying to make one of my pages a status / kill page. i.e. Lots of data is being updated on this page -- mostly active output-only numerical fields and...
Ron, You can use a single white pixel and stretch it out to the size of the display, and then an area map as your button. Something like: <div id="layer1"...
I apologize in advance if this question has been asked before, but my quick review of the past messages didn't find it. I'm a newbie user of the Amulet...
You can call the method reappear() on the widget, even though it is not disappeared it should still redraw it because the name changed. I've never tried this...
Brian, Thanks for the reply, but I'm still not having any success with this. Here's the button code: <applet code="FunctionButton.class" width="80" height="25"...
Hey Paul, Have you tried using two different metas? i.e. one for the disappear along with setting a flag somewhere that the other meta triggers on to...
I do this all the time in a similar manner. In your meta, instead of doing a disappear(), reappear(), try a forceupdate(). This may seem obvious but you...
Thanks, Bob ... forceUpdate() in the meta works! Seems like I tried that earlier (without success), but ... you know how it is ... all it takes is the right...
I am displaying real-time data using a stringfield widget. Although it's numeric data, it's too complicated for the existing numericfield widget, so I am...
Is there any reason to control the Boot Mode, TPC, or Baud inputs from the processor? On the demo board they are DIP switches which seems to be fine; but I...
Has anybody used the new Atmel DataFlash AT45DB041D-SU on thier board yet? If you have, and it worked, did you have to make any changes? I havne't had any...

Thanks for the help; I really appreciate it. One more question. Do you do anything with the Reset line. The data sheet says it needs to be held low for 100mS...
Nope. Just let it float since there are already pullups on the Amulet. I'm sure it already has a power cycle reset on the Amulet board. Like I said, I only...
I am having problems programming the 5.7" touch display, I have currently purchased. It doesn't matter what I try to program to the display. I keep getting...
Hi all, I'm using an Amulet display set up as a slave, with a PIC 18F2523 micro as its master. Every 250ms, the PIC sends a "Get Byte" command to the Amulet...
The first step here is to confirm the chip is functioning properly. Put the dip switches in the following order: 1-3 off, 4 on. Open up hyperterminal (in...
So after trying the steps below, the desired output was not gained. No ascii 'C' was output to the display. Is there some more tests that can be done, or does...
Hi, I am using Keyboard example project. Readme file says, that when user types text and hits `Enter' button the string is stored in InternalRAM.String(n). The...
You can read the string serially by sending out a getString command over UART using the simulator or if you want more control over the port I recomment...
Brian thanks a lot! I plan to use Amulet touchscreen for users to input pin code. I have application running on windows PC. Scenario is following: -...
There is an example under C:\Program Files\Amulet\projects\Examples\Password which demonstrates how to do this using a hard coded password. Basically the only...
Hi There, I am hoping to be able to use a list of check box widgets to represent bits of a byte in the Amulet internal RAM. Each check box would represent the...
A, ' This is already done for you implemented in a checkbox "group". In the PARAM NAME="checkedValue" VALUE="number" — number specifies the checked box...
Hi Brian; Thanks for responding. I guess more specifically what should I use for the unchecked value? param name="unCheckedValue" value="0" If I use zero like...
Alex, You don't need to put an unchecked value in a checkbox that is part of a checkbox group (see documentation for checkbox widget). Since each checkbox can...
The following is with regard to the STK-AOB3202405 product. I'm using the following code to create three sliders with the amulet panel as master and a micro...
