Hi all, I have modified the example program to generate a letter on the PC screen, have not tested it as I do not have the ECIO-40 module. Which is the smallest and most simplest of PIC's I can use with this USB_HID component to generate a single letter on the screen of a PC when a button is pressed...

Good day, I would like to have a go at creating a program for Radio control use on model aircraft, namely a quadcopter. What I do not have the experience in is PWM. How does one input the different signals that the RC receiver is putting out in order for my controller program to know what the pulse ...

Hi All, For those of you that have difficulties installing the new patch 6.1.4.0 where it tells you that it is a patch only meant for 6.1.3.2 upgrade, rerun the previous patch 6.1.2.0 to 6.1.3.2 supplied some time ago as the Flowcode V6 program tells you that it has upgraded and is version 6.1.3.2 b...

Hi guys, When starting up my Flowcode 6 program today, I was informed that a newer version was available for download. I downloaded the patch (Ver 6.1.4.0) and tried to run it to upgrade my software. I am currently running Version 6.1.3.2 on my computer. When trying to upgrade my software to the new...

Thanks for the help Benj, will certainly use this method, will play around with it.

Much appreciated

Hi to all, I have made up a bench power supply and am using the PIC16F690 with LCD output to display voltage output which was relatively easy. I would also like to display the amount of amps that is being drawn. What is the simplest way of reading the current being drawn using the ADC input on the P...

Hi Martin

Thank you for your help, as always it is greatly appreciated, will try your advice and play around with it.
Will let you know how I go.

Hi Guys

I have never worked with the PWM module before, am trying to get the frequency setting at 100Hz, have changed the clock frequency of the PIC to 100Hz but not sure if this is the correct way?? The help page does not describe the Period etc very well, very vague.

Thanks for assistance
Ted

Hi Martin Thanks so much.........once again you have come to my rescue, I entered the 250 number as suggested and it is absolutely stable as can be, I did not for one moment think about the GetAverageInt option, have definitely learnt from this. Much appreciated, it feels so good when one can have s...

Hi guys, Now I have, with the help of Dazz, sorted out the minus temperature readings on my fridge controller using the LM35 sensor connected as per Fig 18 of the datasheet. When I use the LM35DZ sensor in positive temperature applications, the output from the sensor via the PIC to the LCD is very s...

Hi Dazz Your advice on the LM35C sensors was spot on, only thing that I had to change was to remove the " *100 " part of your formula. Following my program below gives you the temp accurately, no need to multiply by 100. So to read the LM35C sensor for minus temperatures, follow the datasheet fig 18...

Thanks to all who responded to my request. Dazz, I saw the figure 18 drawing but was totally confused with 2 outputs to the PIC instead of one, now that you have explained to me that I need to take both into ADC inputs and make the calculation, it makes a lot of sense!!!! I will try it and let you k...

Hi all, I have eventually finished my fridge controller which works perfectly well on a breadboard using 2 pots to simulate the LM35 sensors, but am having difficulty with the LM35 sensors (one for cabinet temp and the other for the evaporator temp) When simulating the sensors on the breadboard, I u...

Thanks Martin......I picked it up when I tried to run the program on the breadboard......duuuuuuu!!
I forgot to change the pin configuration on the LCD.

I am getting old now!!

Go well!

Hi guys I am experiencing a problem with a V6 flowchart that I have created to control a domestic fridge. The problem being that when I step through my flowchart, the program and the slide switch, which simulates my external defrost timer switching "on", works perfectly well, however, when I run the...

Hi Steve

Thanks for the info, will check it out.

Hi Guys I have been requested by my friend to design a refrigeration controller for him. The main program that controls the compressor etc is straightforward, as a relatively newbie to Flowcode V6, what I am struggling with is the defrost timer and defrost heater cycles as there are 4 defrost timing...

Hi MJU Thanks for the flowcharts, your initializing routines work very well, I tweaked the programs a bit to enable the base module to have an LCD display rather than the RS232 component and the radio modules work perfectly well thank you, can now send text Bytes to the Rx LCD. Am now trying to get ...

Hi Benj and fellow Flowcoders, I have tried everything to get your nRF24L01 radio component to work, but to no avail. Has anyone been successful in creating a flowchart in Flowcode V6 that actually works? If so, PLEASE post it on the forum so that we as amateurs can learn from it, I have almost no m...

I am currently playing around with Benj's programs posted above. As I am still a novice and do not understand all the terminologies etc, please forgive my dumb questions :oops: . Can someone kindly assist me in the following: In the component macro of the NRF24L01 there is a "FSEL" that is connected...

Hi Stuart

I also battled with the DS18B20 temp sensor and eventually dumped it for a LM35DZ sensor, much easier to program and works perfectly well.

The fact that there is not even one reply from anybody at Matrix just shows their willingness to keep Flowcode V6 up to date and current with modern components!! Many of the components supplied with the software it seems are outdated and have been dragged along every version right from the beginning...

Is there any chance that a component feature could be supplied in Flowcode V6 for the Microchip MRF24J40MA radio module?

Thanks

Thank you Steve...much appreciated.

Hi Benj

Thanks for your solution, will build up a resistor chain on my breadboard and play around with the values.
