The PIC16FA features 4MHz internal oscillator, bytes of EEPROM data memory, a capture/compare/PWM, a USART, 2 Comparators and a. especially easy, as the same MBasic code runs on any supported PIC, except, of course, for a For smaller projects, the 16F is worthy of consideration.

Matrix user forums For users to discuss using Matrix products. I have downloaded that file but it is written using V5 flowcode and I find it is difficult for me as a starter to convert it into V6 as there is no ADC and EB display module in the dashboard panel and connection made to chip.
I will be using LM35 Temperature sensor for the Celcius application. Those resources should help you get started with the basics. Kersing I will go for the learning center to look for the information.
I am attaching my v6 flowcode file for your help and correction. I notice there is no function when I try to connect. If it cannot be connected to chip then I could not run the flowcode simulation at all.
You do not have the required permissions to view the files attached to this post. Maybe Matrix team cous help here? If you point in chip window the A port pins, it shows like the LCD is connected to them?

Once you have done that we can assist you further. Martin If you read a post that is useful, please show appreciation by clicking on thumbs up Icon. There coufs no ADC available for this chip.

Thank you for your 16fA tutorial file for me to try out. And for the LM35 sensor, I am able to make assumption by varying the LM35 sensor to match the set temperature and it is able ‘on’ then to cut-off the output heater Led. I am happy to go that far Now, to go further Thank you in advance. I appreciate the help to beginner to get thru’ this learning on ADC topic to control an output heater.
The pot on max shows C yet LM35 only goes to C. If you are looking at higher temperatures than C then you should be looking at an alternative temperature sensor. But I also know that LM35 max. I could not coirs any linear sensor beside LM35 that ca go more than C.
So, Ciurs construct this flowcode basically is to start learn about ADC application with flowcode. For example Epcos BGF can measuring higher temperatures of up to C Luckily Flowcode 6 and above has thermistor component available within the inputs section so should be relatively straight forward to implement.
For learning purposes, it would be best if you added the component yourself and see if you can get flowchart to work.
If you get stuck I can assist further. I used the search window but there is no Epcos BG item listing. I check the EBM user guide, the information does not tell us as what related to the property setting. The user guide just tell us on hardware connection. Thank you so much, if you could provide this help for my learning.
The component calculates the temperature of the thermistor by using an ADC to read the voltage from the potential divider created by connecting the thermistor in series with a fixed value resistor.
Coufs the component properties the value of the fixed resistor is entered into the RESISTOR property, and the resistance values of the thermistor at various temperatures is 16g628 in the properties labelled M25 to P, where M25 is the thermistor resistance at minus 25 and P is the thermistor resistance at degrees positive. Hence this component, at the moment, only works up to degrees. The component creats a table of expected ADC values, called sample points, for each of those temperatures.

If it is between two points then it calculates the pci between the two and calculates the approximated temperature. This method is called linear interpolation.
Maybe you could do something similar but extend the sample point table to ? Hope that helps Leigh. This is base on the max.
Now when I run the simulation, I could set the desire 1f6628 and when I moved the thermistor sense temp. This seems I have met my first objective. So far so good. I am, of no idea of how to write the flowcode to control this limit. I need help on this to move on.
