Hello

Check out the bit banged rs232 out code available from here.

http://www.matrixmultimedia.com/Flowcode_Examples.php

This will allow you to use your existing hardware via a software UART. Then simply use the bit bang routine to transmit the required data to the display.

Hello Leela

To interface with the sensors you will need one of our analogue boards EB003 which has connectors for connecting the Vernier series of sensors. You can look at the EB003 datasheet in our E-Blocks datasheets area of the website to find out the specific connections to the sensors.

Hello Here is the Bluetooth module. BLU2i V2 Bluetooth module BLU2i Bluetooth Module Spectre And here is the Hirose connector Bluetooth connector (DF12) DF12-3.5-40DP-0.5V-80 2001 ICE Do you mean a schematic for the bluetooth board or the bluetooth module? If you need the bluetooth board schematic t...

Hello Jag Im afraid that pins RA6 and RA7 are hardwired to the oscillator circuitry on the HP488 V3 Dev board so even if you disable the external oscillator in the advanced options of PPP you will not see the LEDs lighting up. However if you are then going to take this to the next level eg your own ...

Hello Mark

The MCLR pullup resistor is 10K and labelled R34 (just above the ICD2 / USB jumpers) and connects to pin 13 of U3. I will private message you with a clearer schematic of the board.

Hello Do you mean digital pot E-Blocks? It should be really easy to use flowcode to diaplay the output of a pot onto an LCD or set of 7-segs etc. We also have example programs available online that demonstrate dc motors, servos and steppers. We sell a actuator panel if this interests you that contai...

Hello Carl

The latest version is 3.4.7. You can download the update from here if you wish.

Hello Chevvy The FCD file name appears as a device in the target list. Eg if you make an FCD file named 18F2455_ben1.fcd then it would appear as 18F2455_ben1 in the target device list. You will need to restart Flowcode for it to detect any modifications in the current target device FCD file. This co...

Hello Carl

Thanks for the program.

If it is a glitch then im not able to reproduce it here. Both switch types act to clear the EEPROM via the simulation. Which version of Flowcode 3 are you using?

Many of you will be aware that the BTEC National has changed and that there are two units that now cover microcontroller/microprocessor programming. Here we look in brief what this means to you: Unit 62 - Microprocessor systems and applications This unit is designed to give students an understanding...

Hello This is a great topic ! very useful. 8) Using two or three bytes at the start of the EEPROM would pretty much guarentee that you have the correct values set. (two is probably plenty in most cases) Eg 1 byte at the start gives a 1 in 256 chance of failure. 2 bytes at the start gives a 1 in 6553...

Hello

Im afraid that the Bluetooth board does not currently support this. However if you wanted you could rig up the RS232 board to forward the signals to and from the bluetooth board. Not sure if the 4 signals (TX, RX, CTS, RTS) would be enough for the UWTerminal software though.

Hello Jag Thanks for the appreciation. :) In response to your questions. 1) Yes this is correct the analogue pin that shares pin RA3 is connected to the vernier analogue sensor input. 2) Depends on the Microcontroller, some PICmicros have RA4 and RA5 pins, In this case these would be connected to th...

Hello

Unfortunatly Flowcode V4 will not be ready for some time. Flowcode V3 AVR provides all the same functionality as the PICmicro or ARM versions and is capable of directly importing programs from either of the other two device versions.

Hello Vernier is a copmpany that make sensors for embedded and other applications. Their full range of sensors can be found here. http://www.vernier.com/probes/index.html Also they use the fairly common style of connector to attach the sensors so it is possible for our customers to create their own ...

Hello Jules The example may not simulate properly. There is a bug with the timer0 interrupt simulation that means it will sometimes not run correctly. It will however always work correctly onboard the chip. If you ever have any problems check that the clock input for the timer is set to CLKI and not...

Dear Benj. I am looking at the frequency conter example but it doesn't seem to simulate properly but I sort of know what it is doing. However I would like to know how to work out the code to count the frequency as follows: Look at a pin to go high. Start a counter at say 5MHz and stop it when the ne...

Hello Jag

A lot of the PICmicro devices have a reduced set of I/O connected to PortA. All 8 leds / switches on portA will only be available to the PICmicro devices without the reduced set of I/O pins.

Hello

You should be able to download the latest firmware for the AVRISP programming module from Atmel's website. Sounds like a simple firmware upgrade. This should let you get your programming board up and running again.

Hello

You can use the comparusin charts available from Microchip's website to help when selecting a new device.

Hello Wolfgang

Yes it is likely that we will create a Flowcode component for the MIAC like we did for the Formula Flowcode micromouse, currently the component is unavailable.

Hello

For programmers that will interface directly to Flowcode you could try any one of the following.

EB006 - Multiprogrammer board
HP488 - Development board
ECIO - Low cost USB dongle board - I think the experiment kit for this has just come down to Β£29 which includes the programmer board.

Hello

Yes ok Ill try to remember to dig it out tonight.

Hi Chevy Good to see you back, I dont quite understand what you mean by PWMs of 129mhz and 12mhz. The PWM running flat out with a 19.6608MHz clock could only run at a possible speed of 1.6MHz and thats only if you have a period register set to 2. Not very useful. Have you tried the HS oscillator set...

Hello

Any chance you can manually change the FFD8 IO address to use 0378 by typing the new value in.
