I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one. So, standard solution - build one yourself. I designed a simple sinewave generator based on a Analog Devices AD9832 CHip. It will generate a sinewave from 0.005 to 12 MHz in 0.005 Hz steps. That s pretty good, and definitely good enough for me ! But while waiting for the AD9832 CHip to arrive, I came up with a very simple version of the DDS synth, using just the 2313 and a resistor network.

The TMS320LF240xA and TMS320LC240xA devices, new members of the TMS320C24x generation of digital signal processor (DSP) controllers, are part of the TMS320C2000 platform of fixed-point DSPs. The 240xA devices offer the enhanced TMS320 DSP architectural design of the C2xx core CPU for low-cost, low-power, and high-performance processing capabilities. Several advanced peripherals, optimized for digital motor and motion control applications, have been integrated to provide a true single-CHip DSP controller. While code-compatible with the existing C24x DSP controller devices, the 240xA offers increased processing performance (40 MIPS) and a higher level of peripheral integration. See the TMS320x240xA Device Summary section for device-specific features.

The XC226x derivatives are high-performance members of the Infineon XC2000 Family of full-feature single-CHip CMOS microcontrollers. These devices extend the functionality and performance of the C166 Family in terms of instructions (MAC unit), peripherals, and speed. They combine high CPU performance (up to 80 million instructions per second) with extended peripheral functionality and enhanced IO capabilities. Optimized peripherals can be adapted flexibly to meet the application requirements. These derivatives utilize clock generation via PLL and internal or external clock sources. OnCHip memory modules include program Flash, program RAM, and data RAM.

1、直到批號為0645的片子，CHip erase指令還是不可靠的， 這在datasheet 52頁有描述。 2、芯片的頁大小寄存器只能寫一次（OTP）， 如果配置為每頁512字節(jié)后就再也不能寫回每頁528字節(jié)了。 3、網(wǎng)上很多例程是舊版的161B的程序，跟161D操作指令有不少差別， ATMEL已經(jīng)不建議使用這些舊指令了， 移植的時候注意對照DATASHEET修改過來。 4、寫入時一定要查詢狀態(tài)寄存器的忙碌標(biāo)志， 否則后續(xù)指令無效，外部的RYD/BUSY#管腳反映的狀態(tài)， 并不能作為寫入的參考，當(dāng)初就是在這個地方卡了3天時間。 5 部分函數(shù)做過測試,其余難免有錯

This software package contains the USB framework core developped by ATMEL, as well as a Mass storage driver. The MSD driver uses the internal flash of the CHip to operate as a disk-on-key. The following files are included : - core/ -> Source code for the framework core -> Makefile for the core - msd/ -> Source code for the Mass Storage driver -> Makefile for the MSD driver - bin/ -> Compiled binaries for every supported CHips - lib/ -> Lib v3 files for every supported CHips - ./ -> Makefile for the framework -> Startup file

單片微型計算機(jī)是微型計算機(jī)發(fā)展中的一個重要分支，是把構(gòu)成一臺微型計算機(jī)的主要部件如中央處理器(CPU)、存儲器(RAM/ROM)和各種功能I/O接口集成在一塊芯片上的單芯片微型計算機(jī)(Single CHip Micro Computer),簡稱單片機(jī).由于它的結(jié)構(gòu)與指令功能都是按工業(yè)控制要求設(shè)計的,且近年來單片機(jī)著力擴(kuò)展了各種控制功能如A/D、PWM等,因此我們更多時候稱其為一個單片形態(tài)的微控制器(Single CHip Micro Controller),或直接稱其為微控制器(Micro Controller)。

The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of firmware [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA CHip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.
