Getting Started with STM32F0 32 bit ARM based Microcontrollers : Compiling using Keil uVision 5. Hope you know what is meant by compiling and what is a compiler and what is a project.
These are NOT in the scope of this article, so I won't waste much time on those topic to keep it short and simple. Any project you download from this website is in form of Keil uVision Project. This project has the main source code file and all other supporting files and settings to build the executable file with a single mouse click or a keystroke. The project file is a compressed ZIP archive, so the first step is to unzip (or extract) the complete set of files in a folder in your hard disk drive. After extraction you will get a folder structure similar to this :- Grab'eM APM 2.8 MULTICOPTER CONTROLLER Price in India - Buy Grab'eM APM 2.8 MULTICOPTER CONTROLLER online at Flipkart.com. 3DSimo. Lipo's - 2s, 3s, 4s, 5s..... Hi bbellfly-This is from an earlier post of mine, so it may be more info that you need, but here goes....This nomenclature tells you how many individual cells are in a battery pack and how they are connected.
In theory, you can describe any type of battery pack this way, but it's most often used to describe lithium-polymer packs. The first number (the "S" number) tells you how many cells are connected in Series (S for Series). From this, you can determine the voltage of the pack. A single lipo cell has a nominal voltage of 3.7V. So a 3S pack is a bank of 3 cells connected in series and has a voltage of 3 x 3.7 = 11.1V. LiPo Battery Packs for RC Airplanes. So what exactly are LiPo battery packs and what makes them so special?
That's an excellent question and is the topic of the discussion "what is a LiPo battery? ". This page covers the actual use and care of Lipo packs. LiPo batteries aren't like other types of batteries you've used in the past. If you charge or discharge LiPo's too rapidly there's a good chance you will see some unexpected fireworks. It would definitely be a bad day if that happened inside your house or garage! 3S or 4S lipo? Complete Guide to lipo batteries.
Taken from the page: After seeing the many many posts on LiPoly's and answering similar questions time after time I've decided to put up a guide for using LiPoly batteries.
Lithium batteries are the preferred power sources for most electric modelers today. They offer high discharge rates and a high energy storage/weight ratio. However, using them properly and charging them correctly is no trivial task. There are many things to consider before using lithium cells for e-flight. 1. Lithium cells must be charged very differently than NiCad or NiMH. New Naze32 rev6. Naze32 rev 6 has just been released, I am excited and curious to find out what it is all about :) Is the New version Naze board worth upgrading to?

Power Filter for Video Transmitter and FPV Camera Quadcopter. When powering the FPV video transmitter and camera with the main battery, you often see moving lines jumping in the monitor image, which looks like interference.
This is the problem with the battery is being shared with the ESCs and motors, which draw different amount of current when it’s adjusting motor speed to maintain balance. The varying current it draws, causes the voltage level of the battery to fluctuate, and the voltage fluctuations is basically noise which causes the image to have artifacts. The simplest solution is to use a separate battery only for your FPV equipment, but it’s heavy.
Alternatively you can use a power filter (as known as a LC filter) to clean the “dirty” shared power. I wrote a post on how I built one before, check my LC filter build log out. LC Filter and FPV. LC filter is one of the most basic filters in electroincs, which comprises of just one inductor (coils) and a capacitor.
It is a circuit used to suppress the noise in the power source created by ESC and brushless motors. An inductor resists changes to the current flowing through it: A capacitor resists changes to the voltage across it. See this post for a more sophisticated version of power filter. Apart from the video transmitter power, antenna gain, the FPV range and quality also depend on how noise your power supply is. If you have a independent power source e.g. a separate battery for your video transmitter, you generally should not have any noise issue. When you changes the speed of your motors, it changes the current being drawn from the battery too, therefore it causes fluctuations in voltage level – Noise. Most common video transmitter requires 12V power supply, which can be powered from the 3S battery directly. Related. Where to mount ESC - Quadcopter Arms Or body - Multirotor RC.
A very frequently asked question is: Do you mount your ESCs on your quadcopter amrs or body?
Personally I like to put the ESCs on the arms for various reasons, some people might disagree. Anyway I think it’s more or less a personal preference, here I will list the arguments for both sides. When putting the ESCs under the arm or on the arm, it’s easier to manage and replace. How to choose Motor and Propeller for Quadcopter and Multicopter. You won’t believe how much maths and aerodynamics are involved when the engineers are designing the propellers and motors. Therefore you know how difficult it is to choose the best motor and propeller combination for your quadcopter for best performance.
Fortunately this is not a new subject, and there are so many people shared their experience about this. Also there are some general rules you can follow to choose the optimal and effective motor and propeller combination. What does the ring on ESC do? - The Ferrite Ring. If you have used ESCs for example the Hobbyking 30A ESC, you might notice the cable is wound around a little doughnut ring.
So What does it do? And do you need this ring and is it necessary? This mysterious ring is called the ferrite ring or ferrite bead. It is used on ESC to reduce noise in the signal lead mainly due to the length of the cable. Which Board is Right for Me? For a few months after Raspberry Pi came out, the choice was pretty simple.
If you wanted to talk to arbitrary electronics, your best bet was to buy an Arduino microcontroller board; if you needed the power of an ARM-based processor to run Linux, the Raspberry Pi single-board computer (SBC) was the obvious choice (that is, if you could get your hands on one. Delivery issues are mostly resolved, but last year some people waited more than six months for their Pi). Before Arduino and Raspberry Pi, things were more complicated. Going forward, things aren’t just complicated again — they’re bewildering. Warthox on Vimeo. Choosing Quadcopter Motors and Props. Quadcopter Build for Noobs. All - I have been following various threads on here for the last month or so and have been inspired to attempt my first RC build, a quadcopter.
I will attempt to catalog the build as I go so that other inexperienced builders will have something to reference. Before I get started, many thanks to Old Man Mike (OMM), S11D336B, Signguy, Reverendrichie, Jesolins, and others for their informative threads and builds. Best Quadcopter Motors : Choosing RC Quadcopter or Multicopter Motors Made Easy ... It is best to choose motors that can rotate both clockwise and counter clockwise.
Quadcopters have 4 motors – and for the highest stability, two of these rotate clockwise while the other two rotate counter clockwise. You can buy motors that are either clockwise or anti clockwise only, but that would make the craft a lot harder to fly. Sure, there are algorithms that can take care of the resulting instability for you, but these would be really hard to keep in the air if you are relatively inexperienced and choose to fly in the manual mode. You would need to have some understanding of what pole count of a motor is, but you would not want to fuss about this. While a motor’s pole count does make a difference, you do not have to worry too much about it because all of the intricacies are handled by the electronics.
A motor with a higher pole count requires more voltage and produces more torque – or lift. How to choose your multi rotor Motors/Props/ESC - Guides - DroneTrest. I found this great video that talk about the process for choosing the best motors, props and ESC for your quadcopter. It is a great process you should follow when you are building a new multicopter.
The video focuses on quadcopters, but the rules are the same for Tricopters, Hexacopter, Octacopters etc.. When he is talking about the thrust required for your motors (model weight x 2.2)/no. motors you should try look for motors that have the max thrust values that match that weight. However he talks about motor efficiencies dropping down at higher throttle, but this is usually included in the values provided by the manufacturers, as the thrust tables are usually given at max thrust.

Before I removed the resistor it was a dull red when the voltage drops below 3.3V/per cell, now it can't be missed, either during day or night flight. I also found out that my charger was not balancing my cells properly and one cell would drain faster then the others, this item indicated that one cell was drained compared against the other cells.
