Am trying to convert an Arduino project to flowcode here is the link; https://www.ametherm.com/blog/thermisto ... hermistors

Ok that is what i used Benj but my display shows only 28.68 degrees at full range , there must be something am not doing right with the Steinhart and Hart equation as in Flowcode entry data eg the calculation box. Here is my Temperature (in Degrees C)/Resistance (in Ohms) Table of my 10K NTC Thermis...

Hi Everyone, am trying to make a temp sensor with a 10k NTC thermistor and the Steinhart and Hart Equation, I need it to read the temperature of upto 120 degrees Celsius but am having trouble please check my code, Help show me where i go wrong.And how do we enter a coefficient of say 1.125509474e-3 ...

Yes, i used the cursor option even before i put up this new post and what i did is clear line (1) for one second every time am to display the next message of the menu but it's not as cool as a message that just slides in letter per letter at a desired speed as when you scroll the entire display.

Hi Ben and Martin how are you and to all the flowcoders, hi.Now sometime i find my self in need of scrolling LCD Display line either 0 or 1 to work as menu scrolling,but Flowcode has one option (Scroll Dislay) that scrolls the entire display, take an example like, i have a message Menu of 5 contents...

Well Martin thats all your hadwork,you really did what you could to make me understand the 7seg which proved to be big headed to me in the first start, i really like you mr Martin, wish u could visit me in my country but the bad thing am not that rich to transport u down here.Keep the good work mr M...

Totally zero half lit LEDs only a reflection of a close camera.

Ok i have managed now to make my display look really beautiful with totally zero and i mean totally zero half lit LEDs even with port masking method, this is a great achievement for me as i don't have to use the component macro that take allot of my MCU space. I have managed to do this by clearing a...

Ok i managed to work it out and now it's working with my characters after making seg1=1 instead of 0x73 ,seg2= 2 instead of 0x79 and a 2ms for each digit update interrupt having a total of around 165 flames/sec all together to minimize on the half lit led on my Characters as the reference 1 and 2 wa...

At first i used a decimal point to separate the zeros from numbers of people like 1.00, 2.00, 10.0, 99.0 and then 100 till 999.and the program works very well after Martin told me to use <>32,But now i wanted to replace the decimal point with characters like PE that is 1PE , 2PE, 10P, 99P and then 1...

Ok ive added custom characters, that is PE (people), on Start up display shows 0PE (0 people),now as an object comes close to the sensor, a 1 is added then display shows 1PE (1 person) and so on as the count comes to 10 and above it changes to say 10P, 20P, 99P then 100 without (P) upto 999.Now the ...

Ok got you loud and clear Mr Martin.

I would like to use output icon with port masking like we did in the charger instead of using compenent macro inorder to reduce on code size.

Here it is with port masking it doesnot work but the good side of it is that the code size reduces, pliz take a look at the flowchat below.

Thanks Martin i used != 32 and it worked like a humble dog.Now the option for common pin is there but when you disabled the common pin so that to use your old trick and activate the digit via the output port masking like you did on my old project of battery charger here it does not work that is what...

Hi Martin nice to see you and thanks for the quick response ok another thing is when Benj updated this 7seg I guess he deactivated the option of disabling the common pin inorder to use the output instead to trigger the digits yet that option is really helpful for low space chips like am using here.I...

Hi every one,Ever since Benj updated the common cathode 7 segment to allow for a HIGH on the output i really wanted to test this and see the new tricks Ben added, i really like the part that says (common Type) were you get to choose if you are gong to use a high or low on the output and also there i...

What is the best timing gap between two timers interrupt frequency in code forexample if i use Timer0 and Timer2 in the same code what is the best spacing or it has no problem both can run with the same interrupt frequency? Say forexample if i use two 3 digit 7 seg and one is refleshed by Timer0 and...

Hi Martin how are you,hope you are doing well i would like to take you back on this page; http://www.matrixtsl.com/mmforums/viewtopic.php?f=76&t=21119&start=100 were you provided an Excel file for calculating the required numbers to be loaded for the 7seg.Is there a way you can reprogram it in such ...

Am about to finish my PCB ,point of interest Explain more about this current limit setting and temperature when charged as in what to maintain and what not.Thanks Steve.

Thank you very much Steve001 for the info problem is i can't have a charger with all those specs and i will need to use my battery everyday and it will need to be charged so I better use what i have to charge the battery than not to charge it at-all as i use it, and yes i will have a relay on my PCB...

Or I would say delayCount = FireDelay / 0.058 which will give me 94 and when ever i want to add I say delayCount = (FireDelay + 0.0303) / 0.058 and when i want to sub i say delayCount = (FireDelay - 0.0303) / 0.058 will this be okay?

I will need to find away of auto changing your delayCount in case 0.0303ms was added or sub on or from the initial fireDelay variable which means delayCount will not always be fixed or equal to 94times (it will be more or less than 94 sometimes)but will be changing due to changes of FireDelay as dec...
