Arduino Test





After few days thinking why my quadcopter python algorithm does not work during real test, I finally suspect the pwm pigpio libray does not do the job.

So I decided to test my algorithm using Arduino beacuse it has 4 hardware pwm pins.
I bought Arduino Uno.

So I started to rewrite my python algorithm in C/C++. During rewiting my code in C/C++, I feel to go back 20 years ago...in the 1990s....Use basic functions, keep care low usage memory... Using Arduino is very very different from Raspberry, Logs are basics, you must use serial communication using an usb cable. It is not so easy....But I finally ended my code.

MPU6050 code is finished. I read it and compute roll/pitch. PID and speeds motors are compute too. Now I have to test my code again as I did with Raspberry

I have not yet tested pwm harware pins. I should have do this first but I got a basic problem. In fact, my usb cable between my computer and my arduino/quadcopter is too short ! So I have to wait for a longer cable to test motors.

Attiny13A sleep mode

Attiny : arduino's little brother Arduino is a very good card but if you need a very smaller card size or if you don't need alls pins and less memory, Attiny is a good alternative VCC =Voltage is 2.7-5.5 v Notice : Pins output high voltage is 4.3 volts with a Vcc of 5 volts. For 3.3 Vcc, pins o utput  voltage is 2.5 V  So be carefull, this is not 3.3 volts like Arduino How to program Attiny  To program attiny, just use Arduino IDE.  To do this, you will have to connevt Attiny to arduino.  Arduino will now be used as bridge Initial step Upload ArduinoISP sketch on your arduino : Select card Arduino Uno Load sketch Samples > 11.ArduinoISP  Tips : be sure to unplug all wires before to upload the sketch First step First time and only once, you have to write bootloader on Attiny : Choose 'Arduino as ISP' as the programmer prior to burning the Arduino bootloader onto the ATtiny Select card ATtinyXX Verify Board Properties...
