学习单片机离不开实验，以往单片机的实验往往依赖于仿真机和单片机学习系统，价格昂贵，至使学习单片机的门槛很高，很多人不能跨入单片机学习的大门。近年来，随着FLASH型单片机的广泛应用，采用软件模拟加写片验证成为一种经济实用的实验方法，尤其是随着单片机技术的发展，很多单片机都具有了ISP功能，只要一根下载线即可以编程。STC单片机更是将其ISP功能发挥极致，只要有RS232接口，不需任何其他电路即可实现ISP功能。

ISP 型单片机实验板学习单片机离不开实验，以往单片机的实验往往依赖于仿真机和单片机学习系统，价格昂贵，至使学习单片机的门槛很高，很多人不能跨入单片机学习的大门。近年来，随着FLASH型单片机的广泛应用，采用软件模拟加写片验证成为一种经济实用的实验方法，尤其是随着单片机技术的发展，很多单片机都具有了ISP 功能，只要一根下载线即可以编程。STC 单片机更是将其ISP 功能发挥极致，只要有RS232 接口，不需任何其他电路即可实现ISP 功能。。多年前，本网站为单片机爱好者设计了实验电路板，并公开了全部的软、硬件资料，广受爱好者欢迎，很多人使用这块实验电路板学习并由此入门，同时网络上也出现了很多同类功能的实验电路板，为广大爱好者学习单片机创造了良好的条件。随着技术的发展，本站在原实验电路板的基础上，开发了一块功能更强的实验电路板，该板除保留了原板广受好评的部分外，新增了更多的功能。最大的特点是具有仿真能力，不再需要昂贵的仿真机，即可使用Keil 软件进行仿真调试，使得学习成本大为下降。板上安装了6 位数码管（原板为2 位数码管）；8 个发光二极管；四个按钮开关；一个简单的音响电路；一个用于计数实验的振荡器；At24CXXX 类芯片插座；X5045 芯片插座；RS232 串行接口。

The μPSD32xx family, from ST, consists of Flash programmable system devices with a 8032 MicrocontrollerCore. Of these, the μPSD3234A and μPSD3254A are notable for having a complete implementationof the USB hardware directly on the chip, complying with the Universal Serial Bus Specification, Revision1.1.This application note describes a demonstration program that has been written for the DK3200 hardwaredemonstration kit (incorporating a μPSD3234A device). It gives the user an idea of how simple it is to workwith the device, using the HID class as a ready-made device driver for the USB connection.IN-APPLICATION-PROGRAMMING (IAP) AND IN-SYSTEM-PROGRAMMING (ISP)Since the μPSD contains two independent Flash memory arrays, the Micro Controller Unit (MCU) can executecode from one memory while erasing and programming the other. Product firmware updates in thefield can be reliably performed over any communication channel (such as CAN, Ethernet, UART, J1850)using this unique architecture. For In-Application-Programming (IAP), all code is updated through theMCU. The main advantage for the user is that the firmware can be updated remotely. The target applicationruns and takes care on its own program code and data memory.IAP is not the only method to program the firmware in μPSD devices. They can also be programmed usingIn-System-Programming (ISP). A IEEE1149.1-compliant JTAG interface is included on the μPSD. Withthis, the entire device can be rapidly programmed while soldered to the circuit board (Main Flash memory,Secondary Boot Flash memory, the PLD, and all configuration areas). This requires no MCU participation.The MCU is completely bypassed. So, the μPSD can be programmed or reprogrammed any time, anywhere, even when completely uncommitted.Both methods take place with the device in its normal hardware environment, soldered to a printed circuitboard. The IAP method cannot be used without previous use of ISP, because IAP utilizes a small amountof resident code to receive the service commands, and to perform the desired operations.

On the LPC13xx, programming, erasure and re-programming of the on-chip flash can be performed using In-System Programming (ISP) via the UART serial port, and also, can be performed using In-Application Programming (IAP) calls directed by the end-user code. For In-System Programming (ISP) via the UART serial port, the ISP command handler (resides in the bootloader) allows erasure of one or more sector (s) of the on-chip flash memory.

This demo nstrates the use of the reversible jump MCMC simulated annealing for neural networks. This algorithm enables us to maximise the joint posterior distribution of the network parameters and the number of basis function. It performs a global search in the joint space of the parameters and number of parameters, thereby surmounting the problem of local minima. It allows the user to choose among various model selection criteria, including AIC, BIC and MDL
