Hi,
As adc uses analog whereas Lcd uses digital it's not possible for normal uses to switch between that in an same bit of code. Also not advisable.

Hi Stuart,
You can start reading my following thread if you already not gone through. Here I have shown how to use the sensor. If you manage to use the DHT sensor and the code. I will post code how to send data to RX.

Excellent post to create custom character in LCD. I should try to make my native language characters if could make up to 50 characters.

Hi
Can you please post the link where you get this Flowcode from? This has some problem like Cod7Seg[1] = 0x55 is initialized but other locations are not initialized so how you will send that to slave?

Hi
I haven't checked that in hardware but the following link is saying ASCII code 16 should display ►Play (Forward). If you put printascii(16) in LCD macro; you should be able to check whether it print that character or not.

I do not understand why it does not show locals on the Project explorer. Yes, you are right. That's not available in project explorer. How do you get the variable .Return between Sample_Cap_Touch and Parameters? Return variable is something automatically defined if you declare return type non-void ...

I do not know If I have to create them myself or not. If you copy a part of program to other program...variables are not copied with them, you have to declare the variables to make the code in act. I tried to but flowcode does not allow a variable name with a dot in front. variable that has dot in ...

Hi
Thanks for letting us know. I have checked the CAL file for I2C and it seems that for first I2C erroneously SSPCON2 has been used which is the cause of error.

Note: don't replace old one..make a backup and put this one. It need to be checked by Ben.

Hi
Can you please un-install your free version of Flowcode and try to re-install after restarting your machine and see what happened? If still problem persist let us know so that we can have a look..

Hi
Can you please post exactly what you are trying to do? Please post that in detail so that we can check your code easily and let you know where the problem is. I have tried to follow the but that's not so easy without knowing what in details you are trying to do.
Thanks

Hi Paul, I see what you mean. I haven't read through you post :oops: I have been through Martin's post as that is small :P I have faced similar kind of issue in RS232 Tx,Rx. I have couple of suggestions for you: 1. Instead of Labview please try to send data from terminal (may be Hyperterminal or htt...

Hi What Martin suggested I use that if I have no problem like printing those numbers at starting cursor position and you have nothing immediately after this number printed in the display. But if you for example want to print the number from 17,0 cursor position and three number will occupy 17,18,19 ...

Hi
You can have a look at the following FAQ link...

Hi Here is a schematic for starting point. Start with 8 LEDs and let's see if we can control these LEDs we will be able to control rest. PCA9532.png You have to follow the following programming sequence... '**************************************************************** '* Name : i2c comms test wit...

Hi I would recommend you to use anti-log series to get the approximate value of your logarithmic input. I have did sin, cos, tan series and those worked excellent and believe antilog will work too. BTW, are you need to use natural logarithm or 10-base logarithm? If naturral, you can follow following...

Thanks for sharing. I did exactly similar thing in my FCU (free cooling unit) design where EC fan was monitored and controlled by separate chip.

Nice work Brandonb

Hi,
If you are having this when you compile any flowcode program also. Please make sure you have uninstalled ccs & flowcode and restart your machine and make fresh install of flowcode. You will get the effect of ccs deleted.

Hi, Actually I would suggest you to buy Flowcode v5 as it has lots of new features. Couple of those worth mentioning: 1. It supports a wide variety of data type like signed and unsigned long variable etc. 2. Lots new chip added and fcd corrected. 3. Different interrupts implemented not all were avai...

Hi

You said you are clear about hardware. so please mention which mode you are using dynamic or static? If possible post an schematic of the 4-digit seven segment connected with the chip SAA1064 and also with PIC.

Hi
Have you tried to use this example?

Thanks for the information you have posted. I have modified the Rx code to adjust with temperature. There could be some difference with the actual temperature and the value shown in display but should not be too different with the new code. For more accuracy we need to move to DHT11. But I think we ...

Hi I have noticed couple of issues in the code. I will correct those and post asap. I haven't check your Rx code earlier in details...but checked just now. I have requested you to post simple Rx program not the whole code. It's not easy to debug where the problem is. I can't even find where you are ...

Hi
I would suggest you to make the receiving code simple for the time being to simply test different the RS232 transmission and reception. You can post simple Tx and Rx program. I will have a look if there are any issue still left.

Hi You have had a problem in your RS232 receive macro. I have shown the right format of receiving macro in the snap-shot. you put variable in the nTime place but it should be in return data place. nTime could be 1 if you use interrupt for detecting RS232 reception but if the wire length is loo long ...
