Hi Yefj,
You can refer to the device header file for the MCU, there you can see all the exceptions and interrupts listed for example https://siliconlabs.github.io/Gecko_SDK_Doc/efm32g/html/efm32g890f128_8h_source.html...
Why do you think I will not answer that..can you please clarify..why one should not take advantage of this forum ?? I have been using this forum for the last 8 years and everyone helps as per his/her capability and knowledge.

is the NTC thermistor I want to use.
My question is if I use good tolerance analog components, should I be able to achieve the 0.5 deg C accuracy over (-40 to +40 deg C) range, without doing any calibration?

Hi There,
I want to use NTC temperature sensor in one of my product with MCU having 12 bit ADC..any idea how to take this into production, How we will maintain its calibration and will every sensor will require calibration if we want to achieve accuracy of -+0.5 deg C across -40 to + 40 Deg C.
Yes I understand your point ..But this is proportional control valve and it is normally closed. If I can get the normally open valve then I have to close it till the flow reaches its set point.
If you see the data sheet of the solenoid the coil assembly is on the top of the flow opening and also the flow rate is below 15 LPM . so it is not dissipating the heat properly unless I provide a separate cooling fan.
Yes jiripolivka data sheet of the solenoid says ..opening of the valve is proportional to current flowing through it. I will test the circuit tomorrow and let you know how it goes.. thank you for reply.

you are right .. my concern is heating of the coil.
Hello everyone,
I am using PWM to control a proportional solenoid valve(12 V,340mA) to control air flow rate. The control system is working but the coil of the solenoid is getting very hot. I want to reduce the heat generated in the coil.
After searching on the internet. I found that If I use...
hi folks,
In the attached transistor circuit i want to calculate VCE ..
my analysis " transistor BE junction will be reverse biased and VCE=5v ".
but answer says "Valid Answer range between: 4.26 and 4.27 ".
you can not apply these formulas blindly ...here is some points to remember...
1. firstly suppose transistor is in active region and find out the base current.
2. apply Ic =βIb.
3. find Icsat= (Vcc-0.2)/Rc.
4. If Ic< Icsat. then Transistor is in active region otherwise if Ic>=Icsat then it is...
Hi Arun this is very common in GPS receivers...when you start your receiver very first time they require some special information called Almanac and
Ephemeris .. this might cause inaccurate information. To get accurate information keep your GPS receiver ON till the Almanac and Ephemeris...
