okay..so you might not be a complete loof but I am..so I’m writing this post to the my future self..because he forgets a lot needs his memory to be refreshed every once in a while..go grab a pen paper. K.F- It is an iterative mathematical process that uses a set of equations and consecutive data … Continue reading Kalman filter for loofs
here’s how GPS works there’s a clock involved..the satellite sending out GPS signal has it..and satellite is orbiting the Earth about 20000 Km above surface with 14000 Km/Hr. So there’s a very precise clock on-board a very fast moving satellite..what da hell/..? Satellite sends a signal consisting of its orbital data and current timing. so … Continue reading break-a-leg/rtk
Kalman Filter, its a very versatile technique..ask about its usage..first used in navigation system of Apollo missions..used in Image processing and vision and stuff..and used in Robotics of course. Here’s why we need a filter to compute Orientation and explains complementary filter, which works okay. Complementary filters are good and easy to understand..but they are static..i.e. gains … Continue reading Kalman for half-witted
ARM..Advanced RISC Machine. I wasn’t really paying attention to the CMSIS and Startup files earlier…turns out they are quite knowledgeable. just a basic thing that I think one should know to avoid confusions- “Large and complex systems are designed by making small parts work independently and then integrate them together..so ADC’s I2C GPIO’s are not … Continue reading ARM CORE M3 Basics
First off Quadcopter project which I worked on, is open source and over GitHub, Happy experimenting..!! so I got to know about of couple of mistakes I did- Difference between Plus Config and X config of a quad- Its a pretty basic thing, X config flies as X and + flies as plus. Now to … Continue reading Foolish mistakes..!!
Just tested this sucker today..using custom RC transmitter made from Nordic 2.4GHz Transceiver-nRF24L01+..it works great, but my pilot skills are particularly bad..I might have to tweak the code a little..and I’ve been working on with STM32 cortex m3 so I’m gonna upgrade the board from Arduino to STM32..and then we’ll get to position hold and … Continue reading Arduino Quadcopter- Epic fall and fails
Problem with this board Mini STM32 v3.0, its quite old I guess..almost 7 or 8 years old, so it doesn’t came with embedded circuitry for debugging, I’d have to buy ST-Link v2 for that. I wrote a simple functions for printing data on computer screen using USART1 of the STM32F103RBT6. There was a little hiccup for … Continue reading UART debugging with STM32F103RBT6
Recently I had bought a RC transmitter which I didn’t really used at all, so I returned it and bought Mini STM32 V3.0 and it came with an TFT which is only impressive the first time you power the board. To my surprise there was barely any documentation available for this board plus I spent … Continue reading Getting started with STM32
