# stm32 external interrupt always pending

In my project based on stm32F107 i use four pins (PINE 12-15) to catch rising level on them.

My problem: two pins always produce external interrupts but there are no rising level on them and other two pins never respond to rising level.

Since you ask about debugging methods for problems like this, the absolute first thing I would do (after making sure the microcontroller is properly bypassed and the power is good) is to get this working flawlessly with ONE interrupt configured and enabled, and then and only then move on to more than one. Add them one at a time and see where things go wrong.

I don't know what your particular printf is doing. I assume it goes to some semihosting tty in your dev environment. In any case, I would lose it until I have this worked out. Use some GPIO output as indicators that the interrupt was received, probably toggling on each one. As a rule of thumb, long complicated stuff is to avoided in interrupts. You might try disabling the interrupt while you're in it, and reenable on the way back out. That printf takes up a lot of clock ticks, and bounce (see below) might be retriggering.

Another issue would be switch bounce. You may be triggering an interrupt every time you flip the switch. Even when you flip the switch OFF you probably have rising edges. You can hardware or software debounce, but again, until you have a grip on it, I recommend triggering your interrupts clean from a digital output on another port.

Also, using a multimeter here really isn't the right tool. If the problem lies with the signals going to PORTE pins, there's no way you will find it without a scope. If everything else doesn't work, you should try to handle these inputs better, but without knowing specifics of what they are now, we can't really advise you on this. If you had a scope, you could use the interrupt to set a bit high, trigger the scope on that, and look at the portE signal that caused it.

If stepping through your problem this way doesn't help you figure out the underlying problem (or someone with a better eye than me can see the error in your code), update to let us know the step where things go wrong and we can take another crack at it.

• Thanks for answer. I've tried to simplify my projects and check single exti. All i can say: either there is some hardware mistake (em influence) on board or it is some stm32f107 internal bug. – r_spb Sep 30 '15 at 13:41

# Markov chain: relation between hitting time and transition probabilities

Let $X_n$ be a Markov chain on a countable state space $E$. For $x\in E$ let $\tau_x:=\inf\{n\geq 1\vert X_n=x\}$ be the first hitting time.

What can be said about the relation between the transition matrix $p(x,y)$ of the Markov chain and the probability of the first hitting time $\mathbb P(\tau_x =k\vert X_0=y)$?

Is there a general explicit relation or is there a non-trivial class of Markov chains for which the relation can be calculated explicitly?

-
For every $k\geqslant1$ and $x$ and $y$ in $E$, let $h_k(x,y)=\mathbb P(\tau_y=k\mid X_0=x)$, then $h_1(x,y)=p(x,y)$ and, for every $k\geqslant1$, $h_{k+1}(x,y)=\sum\limits_{z\ne y}p(x,z)h_k(z,y)$.
Consider the matrices $p=(p(x,y))_{(x,y)\in E\times E}$, $h_k=(h_k(x,y))_{(x,y)\in E\times E}$ for every $k\geqslant1$, and $d_k$ the diagonal matrix with the diagonal of $h_k$. Then, $h_1=p$ and, for every $k\geqslant1$, $h_{k+1}=ph_k-pd_k$.

What is Length? (With Definition, Unit & Conversion)

August 24, 2022

Table of Contents

This post is also available in: हिन्दी (Hindi)

When you see objects like trees, buildings, bridges, roads, etc., what type of measurement comes to your mind? Obviously the height or the length, or the breadth. Height and breadth are also a form of length.

Measuring length means measurement of the size such as the height of any object, or distance from one to another with the help of measuring tools like a ruler, measuring tape, etc. For example, the height of trees, buildings, and bridges can be measured in metres, the length of a road can be measured in kilometres, and the length of a notebook and pencil can be measured in inches using a ruler, etc.

Let’s learn what is length and its measurement and units in detail.

What is Length?

Length is the term used for identifying the size of an object or distance from one point to the other. Length can be defined as the measurement or extent of something from end to end. The length helps you in identifying a larger or a smaller of two or more objects.

For example, the length of a notebook tells you how long the notebook is.

What is Measurement of Length?

Measurement of length can be defined as a process of identifying the length of objects in some standard or non-standard units. Knowledge of measuring the length of an object is one of the basic skills you need in everyday life.

You can measure the length of an object by using different units like metre, centimetre, feet, an inch, or by using a handspan, foot span, etc. There are broadly two types of units that people around the world use.

• Non-Standard Units of Measuring Length
• Standard Units of Measuring Length

Non-Standard Units of Measuring Length

Handspan: Handspan is the maximum distance between the tips of the thumb and the little finger. It is generally about $8$ inches, but it depends on your hand.

Foot span: The foot span is defined as the distance between the point of the toe and the heel of the foot. This again may vary from person to person.

Cubit:  The cubit is defined as the length of the forearm from the elbow to the tip of the middle finger. This unit of measurement is different for different people.

Maths can be really interesting for kids

Standard Units of Measuring Length

Standard units are predefined and are based on some fixed or standardized. These units do not change from person to person or object to object. Suppose, there are two people measuring the length of a pencil with a ruler. If they use the standard units, they will get the same value.  Some examples of measurement of length using standard units are centimetre, metre, kilometre, inch, feet, yard, etc.

The standard units of measuring length are broadly divided into two types.

• Metric System of Length
• Imperial System oF Length

Metric System of Length

The metric system includes kilometre, hectometre, decametre, metre, decimetre, centimetre, and millimetre. There is a relationship between these units. The base unit is a metre.

The units used in the metric system are given below:

The relationship of every other unit with the base unit (meters) is given below:

Imperial System of Length

The imperial system includes feet, yard, inches, etc. The relation is given by:

The conversion from the metric system to the imperial system is given by:

The conversion from the imperial system to the metric system is given by:

S.I. Unit of Length

The S.I. unit is an international system of measurements that is used universally in technical and scientific research to avoid confusion with the units. The S.I unit to measure the length is given in metre (m). The metre is the base unit of length.

How to Measure Length?

There are two sides of a ruler. On one side, we see centimeters/millimeters and on the other side, we see inches. The following steps are required to measure the length of an object:

Step 1: Choose the unit in which you want to measure the length of an object. If you want a value in cm/mm, then use the cm/mm side of the ruler. If you want the value in inches, then use the inches side of the ruler.

Step 2: Find the $0$ mark on one end of the ruler. Align the zero mark with the starting edge of the object to be measured.

Step 3: Look at the endpoint of the object and note the value. For example, in the below figure, the length of the pencil is from $0$ to $14$ cm.

Conclusion

Length is the measurement or extent of something from end to end. To measure length we use three different types of systems, viz, metric system, imperial system, and S.I. system. In the olden days, people used non-standard units such as hand span, leg span, cubit, etc.

Practice Problems

Convert the following

• $12$ m to cm
• $156$ cm to m
• $120$ dm to m
• $8$ feet to m
• $12$ m to feet
• $14$ m to inch
• $128$ inch to feet

# The Chip Problem

1 ISA - Models, algorithms and geometry for computer graphics and vision
INRIA Lorraine, LORIA - Laboratoire Lorrain de Recherche en Informatique et ses Applications
Abstract : The chip problem'' is a fault diagnosis problem in which we must determine which components (chips) in a system are defective, assuming the majority of them are good. Chips are tested as follows: Take two chips, say $x$ and $y$, and have $x$ report whether $y$ is good or bad. If $x$ is good, the answer is correct, but if $x$ is bad, the answer is unreliable and can be either wrong with probability $\alpha$ or right with probability $1-\alpha$. We show that the chip problem is closely related to a modified majority problem in the {\em worst case} and use this fact to obtain upper and lower bounds on algorithms for the chip problem. We show the limits of this relationship by showing that algorithms for the chip problem can violate lower bounds on {\em average performance} for the modified majority problem and we give an algorithm for the biased chip'' problem (in which $p$ is the probability that a chip is bad) whose average performance is better than the average cost of the best algorithm for the biased majority problem.
