Hello

Please can you click on the Chip -> Configuration menu and then click switch to expert mode.

In here you will have to use the following settings to get your program onto the chip correctly.

Hello If downloading the latest version does not help then please can you do the following. create a shortcut to the exe installer by right clicking the file and selecting Send to -> Desktop. Once you have done this find the shortcut and right click and select properties. In the Target text box add ...

Hello

Download the latest version of Flowcode PIC from here. This should install ok on the Vista machine and contains all of the relevant formula flowcode software.

Hello

I've not come across that display but if you have the display datasheet then it should be fairl;y easy to follow and create your own C driver. You can use one of the Custom components to create your 3rd party LCD driver. There are lots of posts on the forums regarding how to acheive this.

Hello

Yes Flowcode V4 will be released for AVR microcontrollers. I assume this will either be at the same time as the PIC version or slightly afterwards.

Also dont be too sure about AVRs overtaking PICs, Microchip has just put in an offer to buy out Atmel.

Hello Sounds like your internal clock speed is not configured correctly. Have a look at the device datasheet for configuring the osccon setting correctly and then match the Flowcode clock speed setting to the value you have assigned. Also the internal clock speed is a RC type and therefore is subjec...

Hello I normally buy ACT http://www.rapidonline.com/searchresults.aspx?style=0&kw=90-1080 or Truxtal http://www.rapidonline.com/searchresults.aspx?style=0&kw=90-3257 However it looks like these manufacturers do not go as high as you would like. Remember you can always buy a 10MHz crystal and then en...

Hello Yes you are correct these devices do support the 40MHz clock. Thats great not spotted that before. You can also use a lower speed clock and use the onboard PLL to boost the program frequency if you wish. There should not be any issues with using a 40MHz clock onboard our hardware. The PPP chip...

Hello You can insert chunks of assembler code using the Flowcode C code icon. This come with a ready example of how to embed the assembler code. Most assembler code will remain the same across devices so you may be able to port the code directly. However things such as register addresses may change ...

Hello

If the sensor is capable of a max sensing range of 4m and you are receiving 8000mm then that is equivalent to 8m. Sounds like it may be hard or impossible to push the range out any further.

Hello there Goldwingers

Congrats your program looks great. We will shortly be releasing something similar to what you have done but designed for the USB devices such as the ECIO. If you want to write a short article about what you did then I will place you into our articles section.

The Buggy component is a simple robot in a maze with two touch sensors mounted to the front of the Buggy. The Formula Flowcode robot has now replaced the older buggy we used to supply. The Flowcode buggy simulation can still be used to aid in designing behavioral or path finding programs.

Hello Im not too sure of all the details and Sean is away on holiday this week. The CCP input is neccisary as this is controlling the interrupt that is monitoring the responce from the sensor. 8000mm is probably the limit of the sensor. However I am not sure of this without digging in further. Have ...

Hello

Which PICmicro device are you looking to drive with the 40MHz crystal? Most of the PICmicro devices will not be unable to run at this speed.

Hello Achillis The 0.1uf cap is the same as a 100nf capacitor, you should be able to get this value easily in a ceramic package. The 100uf capacitors are electrolytic type and are therefore have a much higher capacitance value. The caps should all be in parallel. Look at the schematic for our Multip...

Hello

The distance variable is in mm and has a maximum range distance of 8000mm.

The If IrqCount > 120 command simply detects if the pulse has timedout without returning an echo. If this happens then we still calculate the distance before starting the detect process again.

Hello Ian When you say you are sending bytes 1 through 8 do you mean you are sending values 1 through 8 or values 1 through 255. Sending a value of 16 or 0x10 should be correct to set pin D3. Other then this is there anything different for the PortD hardware I should know about. Might also be worth ...

Hello Achillis Sounds like a voltage stability problem. Try adding capacitors near the PICmicro to allow it to power up correctly. Add the capacitors between the 5V suppy and Ground as near to the chip as possible. I would use one or two 0.1uf cermaic caps and one or two 100uf electrolytic caps. For...

Hi John Ok just been chatting with the Flowcode designer and he suggested a way to do your program that would simulate (though not inverted) and also would allow you to define the components as positive and negative. To acheive this the LED components would have to be different sizes eg normal LED c...

Brainwave!!! Ok what you can do is use the normal LED component to set the LEDs that are the correct polarity. Then you can use the custom component to do the reverse polarity LEDs. This would allow you to use on and off macros to actually switch the reverse LEDs on and off. Unfortunatly this would ...

Hello John Flowcode V4 should arrive near the end of the year, so it depends on how long you have to do your project. You could do the program now and then simply edit the component properties in your program once V4 is released. Alternativly you could create a list of all the components that will r...

Hello

Please could you attach the motion sensor program to the forum and I will have a look what it is doing for you.

Hello John This can be done but it involves a component update from our end which will create some knock on problems as previous programs using old LED / Switches components will not open properly. Therefore it is not as simple as it seems and will require a fair amount of work to get right. I will ...

Hello

Look in the root of the CDs (right click CD and select Open to get around any autoruns). There should be readme files explaining how to complete the installation onto networks.

Hello John Rather then switches to pull the inputs low and high why not just use one to pull high and then use a pull down resistor. Otherwise when neither your pull up or pull down switch is pressed the I/O pin will be floating and may lead to errors. As for the LEDOn and LEDOFF functions yes you c...
