hi all
over the past few days/weeks ive been working my way through this entire thread, i havnt read everything proply yet, started doing big jumps because theres just so much! but i will get through it. im hooked, and i wanna build a df!! cool hey. im currently in 3rd year electronic engineering in south africa (now you really do have people from all around the world) and im looking into building it next year for my final year design project, and if not for university i just want to build 1 for myself because they look really cool. so i want to get all the info and plans and thoughts done early so next year i can jump right into it without reading 85 pages of forum when i should be building my design...
im fairly clued up on programming a microcontroller (atmel avr's) the chip we've been using is the ATmega8515., and im in the process of studying PID control loops and all that stuff. one thing im not super jacked up on is RC stuff. ive had my share of radio controlled cars, ive built a couple, never more than 2 channel, and theyve all worked but i dont know exactly whats going on. could one of you 'experts' give a breakdown or flow diagram of what exactly happens from the transmitter until the signal reaches the micro.. from what i gather, you have the receiver (4 channel minimum) which basically feeds right into the chip and the chip does all the rest (assuming the chip has A/D capabilities), or are there some steps in between. has anyone drawn a block diagram of the entire system? (with nested blocks showing feedback control etc) sorry if this has all been discussed but i havnt read through everything yet, suppose i should do that before piping up here but you know how us engineers are, anxious to get ahead.
anyway its been great learning all i have so far and im sure il be in touch alot more in the future.
thanks for all the knowledge you guys have shared.
cheers
