HI Mju Had a try as per last message, had a few things on display such as init dataready and read variable but got random results also found that if module disconnected still showed on display as initiated etc, so not sure if its my radio modules as well as the component, will try to link both via a...

Salut olivier regarder la config et assurez-vous que ce qui suit est réglé PortB A / D Activer, changer pour PORTB <4,0> configuré comme E / S numérique sur RETOUR comme je crois me souvenir que sa valeur par défaut analogique sur Reset et cela arrête un écran LCD de travailler Faites-nous savoir si...

Hi Cant post chart as im using a beta version and it might not open all 3 address pins high should be 0x27 in hex so in the component properties either type 0x27 or 39 Let us know how you get on also can you post a flowchart add some comments as to whats wrong. As it will help to diagnose if it does...

Hi Im sure the one i use has that chip, have you a link to the one you are using, all you need to do is add the i2clcd component , the value for the adress should be in the datsheet for the 8574, type the adress in in hex ie 0x27 and it will convert it to the dec equivalent then work , give me a few...

Hi stu
one daft question is your circuit getting enough power supplied to it

HI Stu damn :( , have you a different type of pic to try, my test was running at 8mhz internal osc. One other thing to try would be to change from channel1 to software in the properties (keeping the same pin assignments) . if you've got a spare of the chip you are using you could post it here and i ...

Hi Stu Had a look at the lcd for you, sorry theres no pics but cant concentrate for long periods, open your flowchart, Click on view, Select component debugger. In the component debugger window that opens, click to tick expose component tree in properties pane(something like that) click the pull dow...

Hi
Yes the pickit works fine im presuming you have Flowcode V5 or V6, use the forum search facility and you can find the settins for the pickit

HI Benj
stoopid question i know but wouldnt it be easier to hardcode the addresses as they are specific to this device, so if you added the set address macro you just need to select the addy you want ie 1 or 2 etc.

Hi Benj
doesnt appear to work, looking at the openpipe write macro, it has nowhere to add an adress, whereas the readpipe does, can you check and let us know

Hi Stu Sorry totally misunderstood ,i thought you wanted to flash the display, look at the loop of your chart as yo switch led on wait 10ms then switch off the dataline to the lcd, the botton output needs to be C3 =0 at present it's C1=0 changed chart attached(hope i understood proper this time) Reg...

Benj can you change the address box from dec to hex please I asked for this feature at the start of v6 development to show USB IDs, so far it is still sat in our bug tracker and has not been implemented. We are going to have a go at prioritising all the requests/bugs in our tracker shortly to try a...

Hi Dazz, If its an lcd with an i2c piggyback that you have burnt out,I have one you can have, not sure what you meant here: :? If you really need to flash the lcd try this instead of fidling with the i2c lines which i dont think will give what you want i would do this loop write to lcd delay 5ms cl...

Hi Stu
I wish it was the backpack i burnt out i was connecting my v9 programmer to the breadboard e block and wired wrong on there

Hi Stu last time i did it i destroyed a few tracks so had to solder the diode in a slightly different place, but not sure if the remaining track is strong enougth, but shake like a road drill due to meds at the mo :) If you really need to flash the lcd try this instead of fidling with the i2c lines ...

Hi Stu
Schoolboy error im afraid connected 5v and ground backwards to the ic2 backpack and destroyed the bat 21 diode (did it before)

Hi Stu
Sussed it fer you, been on it all day(couldn't focus today,and destroyed my v9 eboo6), change the address to 39 instead of 27, as the address box is in decimal, so 0x27 equates to 39
Benj can you change the address box from dec to hex please

Dazz

Hi I can also confirm that flowcode works on win 8 and 8.1 i have flowcode v4 v5 and v6 on my pc and all run fine, just remember to disable driver signing whilst installing flowcode , instal you v5 and v6 but dont reboot till both are installed ,as disabling driver signing only lasts until reboot Re...

Hi yutronic the reason the chip view is like that is the arduino useable input/outputs are shown connected to their chip pins, the chip pins that appear unconnected in chip view are ones that are not able to be used as inputs or outputs, if you can see a mistake in the chip view please pm me and att...

Hi
As this is a V5 related question please sign up to the V5 forums and ask in there

Hi
Ive attached a heavy commented flowchart for you , hopefully this will get you started and give you the basics, try and do one thing at a time and when it works how you want then do the next bit

Hi Stu Benj is correct, everything not in brackets conforms to flowcode (and Atmel) pin data , stuff in brackets are the pin labels and functions as per arduino spec) so for example if you wanted to make the on board led flash( d13/led and sck in arduino, you would select pin PB5 in flowcode. The re...

try the new one jon, if it fails reload the original

Hi My original board was working but it's now buried in a project, check the firmware version as i believe the updated one is v1, check in control panels properties, so you may have to update the bootloader. (mine had the updated firmware, I can also confirm xloader is a good piece of software as i ...

Hi Steve

Try these http://www.seeedstudio.com/service/index.php?r=pcb
I've had great results using the $10 service, boards were good quality, screen printed well and readable, but they do take a while to arrive, but to be honest for the price its worth the wait
