Hello! Chipfryer
good morning

Many many thanks for your interest, i am eagerly waiting for your post once you take trials, all my best wishes.

Hello! I am trying to change the "Vref Option" in the settings option of the ADC, i want to know if it is possible to swap the Vref option from VDD to Vref+ and vice versa in the real hardware while running the chart (real time), is there any option of using some "C" code or something else. Thank yo...

Hello! Ben
good morning

Wishing all a very safe and healthy new year.

Any news on this component or can take some more time. Thank you.

Hello! Friends and Matrix Team

Wish you all a Merry Christmas and a very safe New Year wishes, friends especially from Europe do take care and stay safe.

Hello! Ben As per your instructions i added the Calculation box below the existing ADC_Global_ST = FloatToString$ (ADC_Global_Real,1) I ADC_Global_ST = ADC_Global_ST + " " but without success, the display shows the values like before, i also tried the existing AD7680 ADC, no doubt the components are...

Hi! Ben Below are the observations for your knowledge, i have attached the chart, kindly correct if i am doing something wrong, honestly everything is puzzling me, i was expecting to read 4096 or 2048 value, do you think i have fetched the value correctly in the chart, i tried running the PIC chip o...

Hello! Ben As said i tried to run the chart, i added one OLED display to see if there is any change receiving, but i notice once the "GetADC" Macro is called then the chip halts no change after that, nothing, everything freeze. I also checked with one LED in the main loop, it flash well if i disable...

Hi! Ben

Many thanks to revert back, i download the chart and check how it works on the real hardware and keep you posted.

Also thank you in advance for making a component for MCP3201, i hope it is not a big trouble or a time consuming process.

Hello! Everyone Following my previous post (but in a wrong version forum) I would again like to raise my request to know if it is possible to use MCP3201 ADC as a component in FC8 same like AD7680, if yes may i request to know how, in one of the previous post Ben mentioned about using SPI Component ...

Hello! Steve good morning the MCP3201 is an analogue to digital convertor that measurer's DC Voltages. Yes absolutely, MCP3201 is a ADC chip which will measure the output voltage from INA196. Are you looking to read the 4 - 20 mA current ? in this case you will need to convert the current to a volta...

Hello! Steve Thanks for your reply. Yes actually i received one small gadget recently, it is in below link for your reference, this gadget has INA196 to sense the 4-20mA current and also onboard ADC MCP3201, this ADC communicates on SPI, i have copy-paste the description as it is for your knowledge....

Hello! Ben Kindly excuse to dig such an old post but honestly i did not find or you could say understand any relevant top on MCP3201 other then this post. Can you just use the Flowcode SPI component. May i request you or anyone to prompt me how can i use MCP3201, as i do not find any ADC component (...

Hi! Ben

Looks great and loaded with fantastic features, looking to buy soon.

Hi! Ben
Good morning

Thanks for that update, have a good day.

Abhi

This page should help. https://www.matrixtsl.com/wiki/index.php?title=Component:_IntOsc_Helper_(Matrix_Tools) The IntOsc Helper component can be found in Flowcode in the Runtime -> Matrix Tools component catagory. Hello! Ben I tried to use your above post to configure the internal oscillator for PI...

Hi! Ben

Thanks for the update.

Hi! B.Senthil
good afternoon

Many many thanks for the confirmation, cheers....

Hi! Martin

As usual you are a SAVIOUR for me, on contrary many on the forum, cheers to you too.

Abhi

Hello! Martin
good morning

Thanks for your efforts, i am desperately waiting for the chips, hope to receive those soon and i could take the trials.

Abhi

Hello! B.Senthil good afternoon Kindly excuse for the delayed reply, the beginning of the week is always very busy. First of all, many many thanks to you for spending your time to write to me and to explain, i am obliged. To be honest with you i was little worried since i read your earlier post but ...

Hello! Stefan and B.Senthil Thanks for this information, to be honest i ordered few PIC18F26K42 (28 pin) from same range like PIC18F46K42, hoping i would be able to use the 12bit ADC available in this chip, previously i was using PIC18F26K22, but the ADC in this chip is 10bit, unfortunately the resu...

Hello! Everyone Thank you for the wishes Chipfryer and Ben, Shubha Diwali (卐 शुभ दिपावली 卐 ) to all of you. This is a festival of lights, and victory of good over evil. (https://en.wikipedia.org/wiki/Diwali) if any one is interested to know something more about the festival. Ben eager to hear about ...

Hi!

Before Christmas it is DIWALI festival and it start from today so next 5 days holidays.

Abhi

Hello! Martin Many thanks for the explanation about the minimum resolution, to be honest i was not aware of that, something new to learn, i will check the link you provided. Hello! Bachman Thanks to you and Martin too for the suggestion about using the analog ckt, actually the present Op-Amp gadget ...

Hello! Ben good evening Aha yes that might explain things. The ADC input has to be positive, negative voltages will just be read by the micro as 0's. Kindly excuse to repeat, your post clearly mention, but absolutely no chance to recognize the negative voltage? Because in my hardware once i disconne...
