Hello, i would like to modify the attached FC6 program so it will send ten lines of predefined (fixed) text to my computer. The attached file is taken from the USB HID component examples. What it does is just to send a line of text every 5 seconds. I tried to modify the program but i am missing some...

Hello all, I followed Benj's suggestions. i tested the MAX 7219 and it works like a charm! It is much more convenient to output the data as binary if you need to display characters or symbols that the BCD mode does not support. It seems that i am not going to waste too many pins from my micro contro...

Hello Benj ! Thanks for your great help!

it is totally clear the way you describe the float to byte conversion.

I would like to know how to convert the number 1 for example into something like this 0b00110000 (D7D6D5D4D3D2D1D0 -> DP A B C D E F G) ??

Hello all ! Great topic about MAX7219. I managed to flash the leds within a few minutes after i read this! I have a question regarding displaying a float number on a three digit 7 segment Display. For example at the moment i send 0b11111110 to obtain the desired character and it works totally fine f...

Hi Pete, I tried your suggestion but again the results were not very good. I get at least a number on the LCD and i assume that the Load Cell may be a crappy one...therefore i will look for a better load cell to make my test. Is there any load cell which operates well and been tested with this modul...

Hi Pete! Thanks for your reply and your time! I tried to make up a program including your macro. Unfortunately i ended up with no good results although i wont be disappointed at all. In order to avoid a lot of texting here, i will upload the FC6 program with this post so you all can have a look and/...

Hello all,

I would like to read the analogue to digital converter in the link below.

Would it be possible to know how to get the data from HX711 chip?

Is there any FC6 example ?

Hi, another solution is to send ASCII (Number 34 = ") using RS232 component .





Thanks

Hi, thanks for your reply,

I have already configured the modem to operate in text mode.

Hello,

This is a sample of a message that i get some times..

I tried to change the baud rate value but no change on the results as you can see below

Hello all, I was trying to find a reason why the GSM modem would not give correct data while a new message arrives. I made a couple of test with no luck again. One thing that i have noticed is that if i reduce the number of the text characters from 18(CN9435693495OK,3,3) to 2, everything will be jus...

Hello to all! Using Flowcode 6, I was trying to add a few custom characters into the LCD as medelec35 presented above. I managed to add some custom characters but after adding the 9th character i am facing a problem. The problem is that instead of the character number 9 the LCD shows a random charac...

Hi again! I tried the rearranged code from Benj. Unfortunately after the test i observed the same operation as before. I am wondering if the values, "String Array Size" and "Message Array Size" will affect the receiving procedure? Flowcode has these values by default equal to 80. Untitled.png Regard...

Hello, what about if i want to send the degree sign through a GSM modem? I am trying to find any solution but nothing yet.

Hi Benj, Thank you for your reply!

I will try this the soonest.

I see that you removed the component with the AT command "AT+CMGD=1,4" which i was using to delete all the messages. Is there any reason of doing this?


Thank you
George

Hello, finally i found some time to run a couple of tests for the problem mentioned above. 1) I measured the power rails using an oscilloscope, as Benj suggested. The result on the scope was pretty good in term of noise even if I use a switching DC Step down converter (LM2576) to convert the 12V fro...

Hi to all and thank you for your replies! Sounds like a powering problem to me. If you have a scope then look at the power rails and see if you get any high frequency dips in the voltage. Caps will certainly help, tantalum caps are best for this as they can provide large amounts of current in a smal...

Hello, I tried to use the capacitors according the details in the link above, without any change. The current problem that i am facing is that sometimes i receive the sms message and sometimes i don't. I will try to upload the program so you can have a better view. Have you experienced this issues b...

Hi Stuart, thank you for your help!


The Module that i have at the moment is This

I will try to upload the flowcode Program when i will have free time in the weekend


Many thanks
George

Hello, i would prefer to ask this in this topic instead of creating a new one. With Flowcode V6 i am using the well known GS M Module SIM8OOL and i need to receive an SMS message. Inside a loop i read a variable for the incoming message. If i got the variable for incoming message equal to 1 then usi...

Hello and Good Morning, please specify which servo motor and servo drive you are using. I am a bit confused because in the beginning you are saying for servo drive and then for a stepper motor with micro-stepping Driver? Is it Servo or Stepper drive and motor? As soon as your motor drive works with ...

Hello! I have purchased this Ethernet Modules and i would like to use them in my projects instead of having USB communication between MCU and PC(usually with Visual studio forms) which is the way i am doing it at the moment. http://www.ebay.co.uk/itm/281891709522?_trksid=p2057872.m2749.l2649&ssPageN...

Hello Benj, thank you for your reply and your help. In the next video is shown the improvement of the previous code according your advice. The temperature is now displayed fine indeed. The only issue that i can not get over is that when i disable the interrupt in order to read the DS18B20 and re-ena...

I will try to upload a video showing the problem that is described above.

Hello all, i was trying to make a digital clock using six 7 segments displays. I would like to display the temperature with no decimal places. The program runs on the hardware but very often i see random numbers instead of the real temperature. Could someone please check this and let me know because...
