Currently the sourceboost compiler we are using does not support the 10F devices.

Hopefully it will be implemented in the near future.

Hello I have had a similar problem with these chips. I think that the Code Protect gets set automatically in the PPP configuration so if you program with this setting enabled then the PIC is no longer able to accept write instructions. I could be wrong about this but when I manually set this to disa...

We have a range of LCDs arriving here at Matrix and at some point this week I will have a look at the C driver file for the LCD. Obviously there is a small problem with the way it is currently functioning.

Hello Mark

Also you can use a string manipulation icon to do the following

Thanks for the info GJB, a great way to do ICSP from the Dev and Multiprogrammer boards.

Hello Samux

What voltage PSU are you using. It needs to be between 12 and 14 Volts. Also have you tried replacing the PICmicro as it may have become damaged.

Can you use a routine like this

Infinite Loop
{
Read Encoder
Calculate position
Read push button
Update LCD
Delay 10ms
}

Hello When using rotary encoders you have two options. Sequential Coding - Binary position Grey Coding - Binary position only 1 bit changes at a time To implement one of these options requires different code. Sequential Coding: Read the binary position and use that to calculate position and directio...

Hello Pinto

Thats a great idea. We are waiting for the forum software to be updated with an attachment plugin so hopefully the functionality you are speaking of will be available soon.

Hello

Here is the Microsoft hotfix regarding this problem. Please let me know if this helps to solve the problem.

Hello Samux

Are you using a Power supply to power your HP488 or are you using the USB supply. If you are using the USB supply and the LVP mode has been disabled in the PICmicro then you will need a Power Supply to re enable the LVP mode.

Hello By config word I mean what configuration are you sending to the PICmicro eg oscillator mode and chip settings. Also if you are using PLL mode then the PICmicro will run at 1 instruction per clock cycle as opposed to normal operation where the PIC will execute one instruction every four clock c...

Hello Christian

We have experience with a similar problem. It is detailed in the support section.

This should tell you everything you need to know to fix the problem.

Hello

See my responce to your other question.

Hello Christian I would recommend downloading and installing the latest version of PPP. This should allow you to click the spanner icon. If not then make sure you installed the software with full administrative privaleges. If you did not install with full privaleges then you will have to uninstall a...

Yes what Mark has said is a good starting point.

To transmit ascii characters you can use 'A'
or to transmit a string you can use "Hello"

Hello Peter

I think this is what your looking for

Hello Christian The chip is configured by using the spanner icon in the course webpage. You do not need to manually code it yourself. Also if the TOIF flag is not being recognised then you can either replace the flag name with the bit number or you can define the bit number at the top of your progra...

Hello Eddie

We are currently working on a PS/2 VGA E-Block so you can attach a keyboard / mouse or monitor to your embedded system.

Hello

Send your program to support@matrixmultimedia.co.uk and I will see what the problem is.

Hello Eddie One of the last tutorial files deal with strings and passwords. Have a look and you should be able to adapt the code for the keypad. A gopod way to learn how the keypad works is to create a fresh flowchart and play around with the component macros for the keypad. Use the LCD to see whats...

Hello Pinto

I will send you a example file.

Hello The easiest way is to get a PICmicro with 2 PWM outputs and then use the Flowcode PWM component to specify the servo positions. The next easiest way is to do an interrupt driven method. Eg use the timer and set the prescalar to a value as close as possible to achieve a timeout of a multiple of...

Hello MarcB Sorry about the delay with things. We have a very active schedule here and trying to fit everything into the time we have is a job in itself. We have a new range of hardware coming out which is currently taking a lot of our attention. Steve will have the component ready as soon as he is ...
