STM32_Firmware

stm32控制as9854正交波形，仅供参考，自己琢磨。(stm32 control as9854 orthogonal waveforms, for reference, on her own.)

基于msp430g2553单片机的ADC数据采集程序，同时将采集到的数据存入到flash中，并且可以通过串口发送数据。是不可多得的430代码模板。(Based msp430g2553 microcontroller ADC data collection procedures, and the collected data are stored into the flash memory, and can send data through the serial port. Is a rare 430 code templates.)

基于ARM Cortex M0的在线编程（IAP）实现，可实现将数据存储在Flash中，但不影响现有程序，芯片类型NXP LPC1114(Based on the ARM Cortex M0 Online Programming (IAP), the data stored in Flash, but does not affect the existing procedures, types of chips NXP the LPC1114)

S3C2440上实现红外信号的接收的驱动程序。利用一个I/O口，不占用串口。已经在板子上实验通过了。(s3c2440 driver)

磁栅尺开发资料. 用这个资料,可以轻松做到0.48um的高精度磁栅尺.( Magnetic scale development information. With this information, you can easily do 0.48um high-precision magnetic scale.)

speex针对STM32F103系列芯片的移植，内含完整的工程。(speex transplant for STM32F103 series chip, containing the complete works.)

说明：  自己写的基于GPS的通讯倒计时程序。可以直接使用，按键调整时间。希望对初学者有所帮助(The base of GPS communication count time program, maybe help the first person in this project. the key can adjust the time.)
