Hello Ondra What about something like this. If you are getting the most common number maybe two or three times in a row then you could create a loop to read in numbers. If the previous number matches the current number then you have a positive fix. Otherwise stay in the loop and update your old and ...

Ok instead of 20h try using 32 this is the same numeric binary value but using the decimal method instead. Alternativly you could try 0x20 but I dont know if this is supported in VB either.

Hello Please try reisnstalling PPP by downloading the file from the link below. When running the installer you will be given the option to uninstall PPP. Once you have done this please run the install again to install a fresh copy of PPP. Next insert the HP488 into your USB and goto your Windows dev...

Hello Ian

Does Steve's code above not work to detect the logic of individual bits in VB.

If (portVal And 20h) Then
'bit 5 is high
Else
'bit 5 is low
End If

Hello

Which memory locations have you overwritten? was it the osccon register or something similar?

Hello Ondra Best way would be to take an average of the results. To do this create an integer variable and add say 5-10 sets of samples to this variable. Then devide the variable by the number of samples used to get your reliable value. For your case: int val1=1002 int val2= 902 int val3=1002 int va...

Hello

The simulation of Timer0 will not work exactly as it would on the hardware. There should be no problems when running the code onboard a chip.

Hello

I/O pins should be driven to the high impedance state during reset and programming.

Hello

A loop condition of 2 is equivalent to loop forever as is anything over 0. A loop count of 2 will give you two individual loops which should yield more predictable and expected results. Each RS232 read / Write can handle one byte only.

To avoid using the function you could research another string manipulation function that is compatible with your compiler. This would allow you to replace all the calls to the concatenate function.

Hello

You are getting the errors in MPLAB because you need to include the includes.h file. This file is located inside the Flowcode V3/fcd directory you could copy it into your project directory to get it working in MPLAB.

Ok here are the dutch help files.

Hello Jorgen Firstly make sure your connections are ok. SDI goes to SDO, SDO goes to SDI, SCK goes to SCK and a digital I/O pin is being used for the CS. Next make sure that your SPI component properties are ok eg correct frequency, clock polarity, sample timing etc to match the device datasheet. Fi...

Hello John PPP should always be able to auto detect chips if LVP is disabled or not. I think what the datasheet is saying is this. If you are powering the board from the 5V USB supply and the target PIC device has LVP disabled then it will not be detected or programmed. Since you are going to be usi...

Hello Wolfgang

The LED is connected to pin RE2. You should be able to use it in your code with no problems.

Hello Alex Ok Im having problems with getting my hardware up and running but I think that this is just down to my CNC circuit boards not quite being accurate enough for the SMT devices. I will pass you the driver that has been done so far. It is untested for the most part but it compiles and the cod...

Hello Yes you can either connect the PIC micros up directly or use the max chips to provide voltage boosting and therefore extend the limits of your connection. You will also need a common ground connection between the two devices. If you are connecting the pins directly then it may be worth using 2...

Hello

The datasheet can be found here.
http://www.matrixmultimedia.com/datashe ... O-60-2.pdf

Pins C3, C4 and C5 are used by the USB connection and are therefore not available.

Hello

Flowcode comes complete with the Dutch language pack. In Flowcode click on View -> Options and then tick the Override Language tick box. You will then be able to select Dutch from the list of languages.

Hello John The HP488 is capable of running high voltage programming with LVP disabled allowing for access to pin RB3 - RB5 depending on the chip. We also provide jumpers to allow chips using LVP to access the LCD via alternate pins on PortB. I'd appreciate it if someone could please confirm that I w...

Hello Strange that sending RS232 data doesnt work. Have you tried doing a very basic program that simply sends out data. This code should work with the custom interrupt enable icon and the 18F6622 chips. Enable Code pie1.RC1IE = 1; intcon.PEIE = 1; Disable Code pie1.RC1IE = 0; Handler Code if (pir1 ...

The USB pack has now been updated to include a Flowcode target definition for the Microchip PICDEMUSB board. To install the USB pack simply follow the instructions inside the installation folder. The Microchip PICDEMUSB board can be selected by selecting the MCHP_FSUSB as the target in Flowcode. Whe...

Hello Jeff

Can you use RS232 instead? The I2C slave component for Flowcode is still a while off yet.

Great article thanks Jose.

Hello Badger You should just have to edit this line. //display the digit #if (%q == 1) and set it to this //display the digit #if (0 == 1) It looks like the C code file has already been updated to allow for common cathode displays but the actual components have not yet been updated to reflect the C ...
