Hello everyone, After playing around with the system a bit, we seem to have solved the problem. Early in the program, our system attempts to initialize the CF...
Hi again, Yep, that's exactly the problem. I wish I had mentioned that first! As part of the standard "exit" procedure for a C application, I believe the ...
Hello, In my project using the RA-80 TERN board, I run 8 A/D convertors, and write their values to the CF card. The code for both the A/D conversion and for...
Franklin, Just to follow up again, we've repeated tests with LCD, serial port, and Ethernet all in operation on the EL... doing so definitely increased the ...
Hi there, There are actually a number of tricks available for increasing sample rate. You'll find that ultimately CompactFlash remains the bottleneck when...
Hello, Â Â Â Â Â I was wondering whether are there any pre-built GUI buttons available for the UD controller. I am trying to develop a touch screen based...
Hi everyone, I have been successfully using Paradigm C++ under Vista for around a month, running as an administrator. Today, something new. Although other...
Dave, I'm baffled, I've never seen that message before. Must be something system-specific, since you mentioned it used to work correctly. Have you verified...
... available for the UD controller. I am trying to develop a touch screen based application. Or do I need to create my own. If so then would I be able to add...
Hi Chon, Thank you for your quick reply! To answer your questions, I have tested the port with other programs. Hyperterminal isn't included with Vista as far...
Dave, I did some googling around after your previous email, and also found other people with similar.. confused.. complaints. All I know is that it's not a ...
Hi Chon, My USB RS232 device is just a bit old and sluggish, I'm sure a newer one would be faster and be able to cope with 115200 baud. Incidentally, I sent a...
Hi all, I am working with the EL with the Ethernet option installed. When I connect to the network using static IP, gateway and netmask. I have no problems...
Hi everyone, The RA-80 engine I am using has a CF card interface that accepts a CF card with a maximum of 1Gb. None of the stores in my area carry anything...
Hi Franklin, From the point of view of any IP end-point... all it knows about are the settings you mentioned (IP/netmask/gateway). Those are the only settings...
Hi there, One quick clarification: your RA-80 absolutely will accept a 2 GB card. In fact, all of our cards are able to accept CF cards up to any size, if you ...
Hi Ka Lun TAM, I use the EL module with CF cards. My experience is the same, it is hard to get CF cards for my purpose. Also, I have to copy files on the file...
I have a laughably small 8 MB CF card I'd be willing to sell for, oh say $5. It was actually used on a Tern project a few years back. I'll even throw in...
Doug, Well as it happens, for anyone looking for very small cards on that size... TERN does have hundreds (and perhaps even thousands) of new/unused cards in ...
Hi! There is anyway of change the port of step 2 (for example instead of use P4, use P5) ? (even if that involves any hardware intervention). Many thanks! ...
Hi, I need to build an application in realtime which also involves floating point arithmetic. I am using 586-P board. I have a task that need to be run in...
Hi T.W. One very good reason for not accessing hardware floating point from an ISR is that the ISR doesn't usually save the FPP registers. If you're willing...
T.W., The advice in the FAQ is true in general. You CAN use floating point in interrupt routines only if you DON'T use them outside interrupt routines (and...
Bill, Thanks for your suggestion. I will try it. Although I need to use function like sin, atan, sqrt in the calculation so I think fixed point will be quite...
Thanks Doug for your suggestion. Can you give me further suggestion on a multi-tasking operating system? Will it be easy with Tern's 586-P board? T.W...
T.W., There are a few multi-tasking OS's that have been ported over onto the 586-based systems. You can do a search in the Yahoo group for details, there were...
Hi T.W. Well, my favorite OS for projects of this size is MicroC/OS, also known as uC/OS, from Micrium (micrium.com). It's free to use for educational and...
Mario, Step 2 is hard-coded in the firmware that's burnt into ROM... for a large quantity OEM build, we can talk about a custom version of the firmware. But of...
TW, For sin() etc you could use a lookup table- only need to digitize a quarter cycle- then interporlate between data points. A fixed point sqrt() is also not...
