Re: MultiWii EZ-GUI VBAT problem

VBAT problem solved. Some time ago was reported a problem in the VBAT reading into the EZ-GUI. Today I decided to troubleshoot the problem, and I solved it. It was very strange, with the USB cable connected the value in the Windows MultiWiiConf the Bat voltage was correct, but in the EZ-GUI trough t...

Re: Battery capacity??

For what I know you can ruin the battery if they go below 3 V. I have two batteries, one is 2.200 mA/h and another 3.300. When the batteries are at 10.5 V ( 3 cells means 3.5 V each) they charges for the maximum capacity. My batteries, fully charged are at 4.2 V like yours. Try with another battery ...

Re: LCD03 Serial Interface

Forgot to say that, in the config.h file, the serial port used for the LCD03 must be set to 9600 baud

#define SERIAL3_COM_SPEED 9600

Serial port 3 in my example.
Bye marco

LCD03 Serial Interface

Hallo to everybody. I tried to install an LCD03, but soon I realized that it, in the I2C mode, would run at not more than 100 kHz, so I decided to modify the Multiwii code to run the LCD03 in Serial Mode. I think it can be useful to someone else, so I would like to share the code. Attached you'll fi...

Re: LCD03 doesn't work on a Arduino Mega 2560 and GY_86

UPDATE Partially solved. Lowering the I2C speed to 100kHz the LCD works. To do that I commented the following line in the Sensor.cpp file #if defined(MPU6050) void Gyro_init() { //TWBR = ((F_CPU / 400000L) - 16) / 2; // change the I2C clock rate to 400kHz Doing that works the I2C configuration in I2...

LCD03 doesn't work on a Arduino Mega 2560 and GY_86

Good morning to everybody. I am facing a problem with the LCD03 installed on an Arduino Mega 2560 with an IMU GY_86. All the correct options are set up in the config file (eventually I will post a copy, but the problem isn't there) When I connect the LCD (pin 20 and 21 of the Arduino) the LCD powers...

SPI support for MPU6000 IMU

Hallo to everybody, I'm new to the forum and I introduce myself. I'm an Italian pilot and flight instructor, in my flight school I run some didactical activities about software and hardware design. One of the next project is a quadricopter based on an Arduino mini. Coming from a previous autopilot p...
