Matrix user forums

Hi, Benj and others 1) The Hex keypad 4x4 that you mention is not the option I am looking at.. Because like what you mention I have to loose out the * and # key, which 4x3 keypad * is for to 'clear' the digits and '#' key is for to exit from keypad after enter the digits.. 2) Also, the hex keypad 4x...

Benj or can anyone offer some help ?? Thank you..

Hello, all I am a flow code 6 user.. I just want to learn how to interface the Keypad matrix 4x4 to my project using chip 16F876A.. I have tried with using Keypad matrix 3x4 with the flow code 6 and it work pretty good with the flow code simulation, as well as I have tested with the hardware board w...

Hello Benj. and everyone out there 1) After this custom interrupt comparator topic has been posted since 11 January 2018 by me . I have noticed there are quite a number of viewer ( 87 viewer ) are searching on the comparator flow code knowledge and application , but unfortunately there is no answer ...

Hello, everyone out there
Is there anyone out there can help me to solve this comparator issue ? Thank you in advance .

Hello, Benj and everyone 1) I have read thru' the forum article by Dave Squibb and Benj dated 29 February 2016 on the above topic . 2) As I try to test out this V6 flow-code in the hardware circuit and I could not get it working base on the suggestion in the forum . 3) Benj have suggested to use Mod...

Hello, all 1) I missed out some information for your understanding.. That is this project is actually detecting the gas leaking of the gas stove while boiling water and the 7 way dip-switch is to select the kettle timer to match the boiling pot water and it is connected to RB7.. For RB6, it is used ...

Hello, 1) I have searched thru' the above topic in the forum and read thru' Dave Squibb and Jan. Lick forum discussion, back in Feb. 2016 & 2015.. 2) My interest on the above comparator is quiet similar to Dave Squibb discussion forum.. 3) Anyway, I still cannot figure-out how to put this comparator...

Hello, Martin, Leigh and all 1) Thanks Leigh for your thermistor component table and info. I appreciate that.. 2) I have put the thermistor component into my flowcode and I have make some alteration in the calculation icon to match the (i) the trim-pot set temp. and (ii) The thermistor readout temp....

Hello Martin 1) Thanks for your advise to use the 100K NTC thermistor.. 2) For my v6 flowcode, I can only find at the input section, there is one Thermistor EBM003 but not Epcos B57540G as you have mentioned.. I used the search window but there is no Epcos B57540G item listing.. 3) When I click in t...

Hello, Martin and all 1) Actually, my target temperature is at 200 degrees C .. But I also know that LM35 max. temp. is at 150 C max. .. I could not find any linear sensor beside LM35 that ca go more than 150 C .. So, I construct this flowcode basically is to start learn about ADC application with f...

Hello, Martin and all 1) Thank you for the info. regarding the 16F628A that is not suitable for this ADC application.. There is no ADC available for this chip.. Thank you for your 16f877A tutorial file for me to try out.. 2) I have learnt regarding the ADC topic.. I have search thru' using this foru...

Hello, Kersing and all 1) I have went to the learning center help and I have found one video tutorial regarding LM35 with ADC and LCD display.. 2) I have learnt about the flowcode on the above topic and I have started to write with V6 with chip 16F628A.. 3) I have few questions right now that I need...

Thank you...... Kersing
I will go for the learning center to look for the information..

Hello, all 1) I am a starter on V6 flowcode and has litter knowhow about ADC and EB005 display on V6 flowcode.. I wish to learn more how to use the ADC, EB005 display to control an output of a heater device.. 2) I have read thru' from forum LM34 Temp. sensor in year Oct. 2013 by Bill Felker, Martin ...

Thanks, Kersing

Hello... Benj, Dave Squibb, and all 1) I am just starting and keen to learn about how to implement flow-code to this comparator 16F627A/16F628A topic.. 2) I have downloaded the attached flow-code file and start as a beginner to figure out on Dave Squibb problem and solution from Benj, and I have sea...

Hi, Here is the product image photo "PIR AirConFan Timer "

Hello, Martin 1) It is already 1 year over before I am back again in this posting.. Sorry for that because I am working on some other things.. 2) Actually today I just want to say thank you to you for on your experiment flow-code program that you have wrote for my exercise testing.. I learnt a lot f...

Here is the laminator image photo.. skquah2007@yahoo.com

Hi, all 1) Just to complement this learning, I would like to share this image photo to anyone who is interested in this project/product.. This project is called " 1 GO toner transfer PCB laminator " I am using this laminator for my hobby to made PCB.. It is very easy, fast and cheaper on cost of PCB...

Hello, all 1) Today, I have tested my hardware circuit with 16F648A ( same data sheet with 16F628A ) chip .. Load with the flow-code program hex. file ...... Test is successful, and working well on hardware board. Selector switches, start switch and feed switch, one pt. is connected to pin no. and t...

Hi, Benj
1) After looking at the 16F628A/ 16F648A data sheet.. I manage to figure out the c code that for the weak pull up..
2) I am now attaching the revised flowcode file that successful compile into hex.
3) Next step is to hook up my hardware to use weak pull up..
4) Thanks again, Benj.

Thanks.. I will try that out..

Hello, I need help.. 1) I am a novice in flow code and I am learning how to apply flow code as hobby in my project.. 2) Because of flow code, I have bought a license V6 about a couple of months ago.. 3) Now, I am trying to eliminate my resistor arrays in my project and to learnt how to use this weak...
