Thank you!

Hello Bitcraze Community, I am trying to create a closed-loop feedback control system for the Crazyflie 2.0, and I want to use Matlab to simulate the system dynamics. In order to do this, I need the quadcopter's moment of inertia I(xx),I(yy), and I(zz). Has anyone performed these calculations of the...

Hello community, I am trying to look through the Crazyflie 2.0's firmware and figure out how I can obtain the quad's angular velocity in each axis. I have searched through imu.c,stablizer.c,sensfusion6.c, and particularly in the latter, I found some crazy mathematical gymnastics within the code. Can...

Until an easy to use API is in place I would base it of the uart_syslink implementation. All the DMA, NVIC (interrupt) stuff can be dropped and just use the uartSendData function. The pins to use can be copied from the header file. In the deck pinout : UART1 would be the UART4 UART2 would be the UA...

Jackemoore, I have tried to compile your code within the Virtual Machine terminal by using the 'make all' command when I am in the correct directory. At first, it gave me an assembler message saying "fatal error: can't create bin/startup_stm32f40xx.o no such file or directory". So I copied...

Thank you for sharing your firmware.

Hi Jackemoore,

Can you share some of your code used to setup the UART for the GPS and explain the process of appending said code to the CF2 firmware? I can't seem to get my CF to read NMEA strings from my gps.

Thanks for the information.

Hello bitcraze community, Can someone explain to me in explicit detail or point me to a guide on how to setup the UART on the crazyflie 2.0 STM32F405? I can't find information anywhere on how to configure the module. I need to connect a GPS to the CF2.0, and I also need to send this data through the...

Okay. Thank you for the information.
