Decoding PPM using STM32 timer
4.5
Application background PPM is a kind of transmission form, which is based on the combination of multiple data in a specific protocol (protocol can be defined according to their own needs). PPM output, and then use the MCU decoding PPM, to obtain the effective data in PPM. This method can be used in the electronic products, as well as short distance radio frequency technology. Key Technology The data is realized using the STM32 timer on the input capture function to capture the PPM and to decode it in order to obtain valid data. After the acquisition of effective data through the serial port, you can use serial debugging tools for real-time monitoring.

NRF24L01 two wire communication module
3.0
Application background The wireless module can be used as a wireless module for the development of two way communication, and the perfect module can be used in the wireless communication of vehicle, ship, aircraft and other toys. Very suitable for a certain basis, like the use of DIY enthusiasts. Key Technology The wireless communication module based on single chip microcomputer STM32f10XX and nRF24L01. Code division master device (TX) and from the device (RX), the code is completely normal, can achieve a simple two-way communication. Development environment is MDK, so it is convenient to start, you can add the corresponding code according to their specific needs, to achieve the function of their own needs.
