Dear Mr Bosman, Firstly can you downloadthe latest version of PPP from our website and uninstall PPP, delete any files remaining in the PPPv3 folder, and reinstall PPP for m the downloaded copy. that should fix any file problems. Next open up the Installing the USB instructions. Look for the bit on ...

Glad to see you found them.
If you loose files you can always email support@matrixmultimedia.co.uk and we will dig out a set of them for you.

Well, that's what I meant Steve; at least it would be a once-only kinda thing. But on my other thought, I already have a rather expensive software package that I couldn't transfer to my new computer because there isn't anybody on the other end to issue a challenge response. And I have a couple of h...

Go into the C2C options and un-tick the 'insert default interrupt handler' box.
This stops C2C putting in the bit of code that causes this issue.

Thanks.

Was asking about the Herc as I have just recently got the Captain Sim Herc for Microsoft Flight sim and am busy crashlanding that at various airports. Lovely plane the Herc.

Hi Henriks, There isn't at the moment, but it is something we have been thinking about. Flowcode macros are there to encourage code reuse and sharing so ideally there should be an online collection point for them. I'll look into what we can do to put macros online for sharing, and how best to organi...

There should be a Tutorials folder in the Flowcode install folder.
Ifthere is not please email me at support@matrixmultimedia.co.uk.

We have a patched LCD Component on the website ready for downloading.

You can download the patch from:

You should now be able to use custom connections, useful for getting around the LVP/Pin B3 issue.

There should be a datasheet for the HP488 Development board on the ELSAM mini Cd shipped with the board. If not email me and I will send you the datasheet. ian@matrixmultimedia.co.uk The PSU we use is a 13.5V 250mA power supply. 13.5v is recommended, but you can normally get away with 12V if it does...

Dear Herc-Pilot, The connectors are called 'BT connectors' after BT (British Telecom) that used them as standard connectors for telephones here in Britain. (not sure what they are called elsewhere). They are used for phones, modems and sensors. There are two types - left hand and right hand, dependi...

There is also Flowcourse an introductory course to Flowcode programming.

This is available free on our web site, and can also be found on the latest Flowcode version CD's.

The components and icons were created with the C2C compiler in mind, and will work with the C2C compiler. You can change the Compiler location from the Compiler options box. However we have not tested Flowcode with the Hi-Tech C compiler so cannot say if Flowcode produces compatible code or not. The...

We are looking to start work on updating Flowcode shortly after Christmas, but can't say how long it will be as we have a lot to do.

We have been looking at the LCD component to see what the problem was. We found that there is indeed an error in the LCD component. The Pins are indeed hardcoded at the moment. (Amazed that it hasn't been spotted before.) We are working on an update to the LCD component to fix this at the moment. I ...

We don't have a Flowcode component for I2C yet I'm afraid. We are looking at doing one at some point soon, but with a busy schedule we can't say when. However I2C comms is possible using C code. there is a lot of detail on I2C on the Microchip website, and in the PIC datasheets. Below is a bit of co...

Hi,

If you send an email to Sales@matrixmultimedia.co.uk with your location we can advise you on who is the nearest dealer to you.

Hi Fransky, Yes it's more of a Flowcode issue as Flowcode assumes that you have the correct configuration and circuit to use the outputs in a case like that. Unfortunately we can't predict which development board, configuration or circuit the program will be used in, so we must allow for all possibi...

One problem with Flowcode is trying to figure out why the C Compiler failed to compile. We have a small utility that we use here to pause the Compiler screen and see what the error messages are. However it requires you to understand C and C code errors so is not officially supported. However as it c...

generally speaking Port B is used for most operations but watch out for Low Voltage Programming, as it uses pin B3. Port A is generally the 'odds and ends' port with pins doubling up for Analogue, comparator and (especially on smaller chips like the F88) reset and clock functions. Some PIC chips, su...

I thought I would post this as it's a question we get a lot. When the Assembly course was written the standard educational PICmicro was the PIC16F84. The course was written with this device in mind. Since then other PICs such as the 16F88 have become popular for educational use as they have addition...

The _CONFIG Data box is for use with programmers other than PPP. With PPP you can go to the PIC menu and select CONFIGURE to go to the PPP Configuration screen, where you can detect the device and set options such as HS/XT/RC etc. If you are not using PPP the _CONFIG box allows you to point to the o...

When we coded the Analogue component we needed to set a convenient sample speed that would work with any PIC or sensors. The delay D220 was chosen as a reasonable sample speed. We did not foresee a need to set sample speed, so the option was not set. However we can see how such a feature would be us...

The ADC example, Tutorial 26, uses the full 10 bits so you can see the maths involved in displaying the full number. Unfortunately maths on the PIC itself is 8bit so you need to work with multiple variables to implement 10 or 16 bit maths etc. This is especially frustrating given the 10bit ADC found...

Hi Metalicat, There is a problem to do with LVP being disabled on chips. If the Chips have had LVP (Low Voltage Programming) disabled then they will not be detected in the Lite programmer. The chips need to be LVP enabled. This is the default state for most LVP chips when fresh from the manufacturer...

We now have a Flowcode 2.2. patch available for Professional or Site licence users. The patch will be available on the Support page of the Website. Click on the Patches and upgrades link and the Flowcode update will be listed. V2.1. was changes to enable translated versions of flowcode to be created...
