Hi Welcome to microcontroller world! You can go through a free course (Introduction to Microcontrollers) in Matrix Multimedia website to be more familiar and have more fun :) http://www.matrixmultimedia.com/lc_index.php?p=24 BTW, if you are using Flowcode v5 License version you can upgrade your stat...

That's fine. Let me know or better to have a video link. I really like your this idea

Hi Although I believe to deal with decimal numbers floating point and in LCD float2str is useful. But for only one or two decimal place addition and adding decimal number with byte, I must recommend normal arithmetic operation than using Float as that uses huge memory and really slow. Rather I have ...

Yes, of course. That's ready to use. Just I want to make sure that previous one is working. If you want to show both Temp Humidity in LCD simultaneously please let me know. I can change the code to have that.

The Temp and Humidity seem to be mixed up as I get Temp 48 and Relative Humidity 24

Can you please post a video to have look what's going wrong?

Apart from that it changes from temp to RH every 6 seconds...

That's what I did..that is OK

Hi Here is the Tx code without LCD. But I feel you should at least have two LEDs in the TX circuit to show you whether that circuit working OK or not. I put two LEDs in the code one is in PORTB0 and other in PORTB1. RB<0> is ON if there is no DHT11 sensor and RB<1> will ON if there is error in data ...

Hi

Here is the TX and RX code and you will see Temp and Humidity alternatively in the RX display. I kept LCD in Tx here to make sure program is working. If you conform that the code is working I will post code of Tx without LCD.

Great!
One option is just don't connect LCD in TX or I can remove LCD from code but I need to send humidity so it's better I will post new code for both Tx and RX.

Excellent video.Thanks

That's great! Please let us know if you need any help.

Yes, I have made a condition to loop a particular LED color if once switch is pressed and if you press another switch it will loop other color macro. Temp1,2 & 3 are used for switch1, 2 & 3. If you look carefully you will see I have set Temp1,2,3 variable in different switch macro and use that in ma...

Hi, obviously if you are careful in declaring the variable like if you don't need variable value higher than 255. Declare then as byte not as integer.same is true for other data type. Other trick is too use macro and use local variable rather than using all global variable as local variables are reu...

Hi Jorgan,
I understand what you asking for. I've noticed this few days back although it posted long before and I've not updated my Flowcode yet. But as Jonny said it doesn't effect normal users. I'll make a thread if we get couple of bug in the new release. Thanks

Hi, I haven't done exactly what you want but something similar you want which removes the requirement of using pc. I've collected quite a lot of data from different sensors and then made a packet with defined format. Then I've sent those data at a defined time interval through gprs to a remote PHP s...

Hi,
I did notice the issue raised by Martin but I have checked the code and it seemed to me that was not only problem. Tick macro should be called in a loop is mentioned in the help file. I thought that's the main problem in the code and that did work.

Hi

Can you please try the code I have modified and let us know whether this solves the issue or not?

Hi I think I have Flowcode V3 somewhere in my stuffs. Can you please post your program so that I can test that? Please allow me some time as we are not using V3 anymore? You can try using Flowcode v5 free version. If you are not need to strict with the chip you mentioned. http://www.matrixmultimedia...

Hi
Now the RX also changed as we are getting directly temperature value and we don't need to manipulate that in RX. I have modified the RX code and here it is..

Hi Stuart,
Here is the DHT11 code with Tx enabled. In this code Tx transistor is controller by RC1 and data out is RC0 as PORTB is busy with LCD.
Please let me know if you are not clear.

Fine. In that case it will be easy for me. so I will post program for 16f877a

Great! Glad to know that you managed to sort. So now you can add tx program with that. I'll post program with DHT11. By the way which chip you are using for DHT11?

No. You have now full access to the forum and we all try to support you with our maximum capability.

Welcome to the V5 forum

Hi
I can't see anything wrong in the Flowcode config. It should work easily. Have you tried to send data to PC (terminal or Hyper-terminal) over rs232 from PIC?

Hi Stuart,
Did you manged to test the code attached in the link I have posted for DHT11?

Hi,

Not quite clear what you are trying to d here? Can you please tell us what is your goal here?
