I've been messing around with one of the tutorial demos where the LED module is used as a stop watch. Is there a way of blanking the left most digits (minutes) until they are used (more than 0)? I'm just looking to make the display more readable in the dark and removing the leading zeros would be id...

I've just put a Citrix server farm together for a small company. Yes there are limitations on the use of local USB ports and to be honest unless it was a memory stick or digital camera on the usb port which is ok, you can forget about PPV3 working. It really is basic USB access such as memory sticks...

Did you try this?

echase: It's not as hard as it sounds to do in Flowcode. The beginnings of a menu system or at least using a screen to enter characters based on button presses is covered in the example tutorial files which are installed under the flowcode directory. I can't remember the exact tutorial numbers but i...

Cheers for the email saying you are on XP Pro. There are many many reasons why you might get this error and 99% of them seem to be down to other applications messing with C++ and giving you the problem with c4pic3. I doubt very much that it is a problem with c4pic3.exe Firstly make sure you are usin...

If you are doing this on Microsoft Windows Vista, then try this...

Right click on the c4pics3.exe and select "Run this program in compatability mode" select "Windows XP Service Pack 2".

Then run the program as an administrator.

Aha! A bistable relay. Perfect! Cheers for your help. I'm in the middle of designing a complex firing system for fireworks using Flowcode and E-Blocks. It has to accomodate network communication but I wanted a way to remove power to the remote firing modules if they have their own internal batteries...

Would the pic have to maintain a supply to the relay?

Can you get relays that use a coil to open or shut a switch but do not require a continuous feed to maintain the new switch state?

Hi, I'm looking for some kind of switch or relay which can be initiated from a signal from a PIC device. The idea is to power off a device (cut the feed from a battery) if a certain signal is received by the device over an rs-485 or CAN bus comms link. Once the power is cut the switch would need to ...

Would one of these help you?

4bit binary to 4 digit LCD driver chip. I've used a similar chip the 7224 counter for driving 7-seg LCD displays in the past.

Cheers for the answer. Have just come back from a weeks holiday in sunny France and trying to read a French copy of Elektor.

I received my FLowcode and E-Blocks kit in the middle of last week. Firstly, thankyou very much for the prompt delivery and the late nights it has given me. It's a fantastic system and has already sparked some new ideas for projects to complete this winter. However I do have one query based around t...

Cheers Ben. That's a useful start for me.

Hi, I've only just come accross the E-Blocks and Flowcode kit and from what I have seen and tested with on your FLowcode evaluation, it is perfect for my needs. I'm being a bit presumptuous here but wonder if you had more information or could point me in the direction of more info for the LCD used i...
