NRF2.4G SPI communication code Xiangjie
no vote
Application background NRF2401 is a single-chip RF transceiver chip, operating in the 2.4 ~ ISM 2.5GHz frequency band, chip built-in frequency synthesizer, power amplifier, crystal oscillator and modulator and other functional modules, the output power and communication channels can be configured by the program. Chip energy consumption is very low, with -5dBm power emission, the working current is only 10.5mA, the receiver operating current only 18mA, a variety of low power work mode, energy-saving design more convenient. Its DuoCeiverTM technology enables nRF2401 to use the same antenna while receiving two different channels of data. NRF2401 is suitable for many kinds of wireless communication occasions, such as wireless data transmission system, wireless mouse, remote control, remote control toys, etc.. Key Technology Interface pins are CE, CLK1, DATA

STM32F103 balance car program
4.1
Application background By now two wheeled self balancing vehicle development as the background, this project design a number of areas covering multiple disciplines, automatic control, pattern recognition, sensor technology, electronic and electrical, computer, machinery and, two wheeled self balancing robot concept is in this context put forward, the robot to distinguish from other... Through high-speed micro controller STM32F103 complete data fusion processing, smooth and stable attitude information of the vehicle, & nbsp; two self balanced vehicle concept is put forward under such a background, this car coaxial two wheel, independent drive. So we use the STM32 as a two wheeled self balancing robot as the main control chip Key Technology In the control process, the design uses the STM32F103R processor. The SPI module reading values of gyroscope and accelerometer, angle and angular acceleration of the balance of the car. After using the Kalman fi
