Check the Web Server component help file for details on using the variables. "Variables Up to four variables can be used in a web page. This allows you to add an element of dynamic content - e.g. a temperature reading, to your web pages. The variables need to be defined in Flowcode for you to be abl...

It may be a clock or configuration setting problem. Firstly check that you have LVP disabled. LVP (Low Voltage Programming) uses Pin B3 which will prevent the LCD from working (unless you modify your program and use the LCD patch system). Check as well that the Watchdog timer is off unless you are s...

Check to see if you are using a proxy server. If so note down it's settings and then uncheck the 'use proxy server box' whilst using the Internet board. Remember to re-check the use proxy box when you have finished with the Internet board so that normal network traffic can be resummed. You need to t...

No idea off hand. I don't think there is a limit (Steve will be able to say for sure) but having way too many would get confusing and start to become unweildly. So for practical purposes there is a limit based on humna I have had bunches of macros in macros in macros etc. without problem. I don't th...

You can set the configuration word for the various oscillator types, and can configure internal clock settings using C or ASM Code. There are various oscillator settings for the F88 discussed in the following post. http://www.matrixmultimedia.com/mmforums/viewtopic.php?t=82 Other than that I'm not s...

There is a %p commandline parameter that passes the PIC chip e.g. -16F84.

You may need to check the exact format needed by Warp13, e.g. PIC%p for -PIC16F84 etc.

The EB006 board is a PICmicro programmer, able to program a large range of PICmicro controllers. E.g. 16F872 chips. It is not an EEPROM programmer unfortunately. PICmicros are EPROM based The best method to program your EEPROM would be to check the datasheet for that device, and the chip manufacture...

The PIC already has a 'clock'. The TMR0 Timer interrupt triggers at a rate of T times a second e.g 133Hz = 133 times a second. When ever it triggers it runs the code in the timer overflow macro. By adjusting the pre-scaler value you can adjust the value of T that is convenient e.g. 75Hz rather than ...

Ooops. Senile dementia creeping up on me there.

Have you defined Port A as inputs and Port B as outputs?

Hi UKWeb, I tried it here and it worked fine on an 877A with LB6 lighting up as expected. I can't think of anything off hand that would stop LB6 lighting up from a code point of view. Next obvious step then is looking at the hardware. What board are you using? And with what chip? Is there anything o...

Dear UKWeb, There is a RS232 strategy document in the E-blocks memebers area that might be of use. http://www.matrixmultimedia.com/datasheets/RS232%20Board%20C%20&%20Assembly%20Strategy.pdf You will also need to check the datasheet for the device you are using to see which pins to use, and for furth...

What you need to do is get the Config words into your program. With PPP you set up the Config in PPP and it gets sent along with the program. With PICstart plus you may need to add t oyour program. You can use the Add Defines component, or a C Code icon at the start of your program with the config w...

Sending a signal to a PC is easy. The hard bit is getting the PC to do anything with it. Two basic methods - serial comms or manually. Serial comms ========= You can use serial comms systems such as RS232 or I2C etc. to send data to the PC. Lots of Eblocks to help here. And Serial comms is a well kn...

0X00 or 0x00?
Remember C is case sensitive.

Doh! Should haveread the initial post more carefully. With PPP the config word is set in PPP and gets sent as part of the process. The config word is not embedded into the program by default. You may need to set up PICSTART to configure the PIC, or to embed config words into your program using a C C...

Firstly check the settings to ensure that you aheve right target PIC selected, and are configured correctly. Do the tutorial files assemble and run ok? Have you tried a very simple LED on test program to see if that works? Are you using any C or ASM code in your program? If you are still having prob...

We use the following system for IO lines on our boards:

C for PICmicros Lite and ASM for PICmicro Lite only contain a part of the full course. Sample chapters to give the feel for the full course and what it contains. C for PICmicros is limited to the 16F84 device. ASM for PICmicros does not include the VPIC simulator but can be used with other chips as ...

But the only downloads I can find is on here: http://matrixmultimedia.com/flowcode.php So i cant use my PIC board without pucrhasing an upgrade?! Why would you package a piece of software which is completely unusable. Adam It is not purcharsing an upgrade, it is purchasing the product. The version ...

Hi Adam, The versions of Flowcode, ASM4PICs and C4PICs found on the ELSAM CD are Demo sampler programs to allow you to try out the products. They were limited to the 16F84 as that was the main introductory PIC chip at the time those demo versions were written. The 2.0 to 2.2 upgrade is a 'patch/upgr...

Hi Dave, there is an RS232 strategy document on the Eblock members area http://www.matrixmultimedia.com/datasheets/RS232%20Board%20C%20&%20Assembly%20Strategy.pdf This has some info. One thing to watch for is that the Pins you need are on Port B not Port C as is usual for larger chips. The 16F88 dat...

Have you turned the analogue ports off?

the 16F87X devices have analogue inputs on Port A which are on by default and need turning off for digital input.

Try adding an ADCON line to the start of your program to turn the ADC lines off e.g.:

adcon1 = 0x07;

We have added a zip file of Flowcode examples for the Webserver and TCP/IP component to the E-blocks members area.

Members area details should be in the Eblocks datasheets, and with the packaging information.

The Username and Password for the E-blocks area should be on the paper documents supplied with E-blocks boards, and in the Datasheets supplied with E-blocks boards on the ELSAM Mini CD.
