摘要

在嵌入式系统软件开发期间，将软件升级并下载到系统硬件的过程相当容易，因为平台尚未封装在其最终产品形式上。因此，当产品准备交付给最终用户时，需要一个ISP(系统内编程)来升级软件，以添加新功能或修复错误。某微控制器的ISP接口是UART(通用异步接收/发送器)。这个微控制器是一个更大的嵌入式系统的一部分，其中UART接口不可用，可用的接口是SPI(串行外设接口)。在本文中，将描述使用SPI的MSP430德州仪器微控制器家族的自定义系统内固件升级方法。

Custom in-system firmware upgrade for MSP430 Microcontrollers family using SPI

During an embedded system software development, the process of upgrading and downloading the software to the system hardware is fairly easy, because the platform is not encapsulated on its final production form yet. Hence, when the product is ready to be shipped to the end user, an ISP (in-system programming) to upgrade software is needed to add a new feature or to fix a bug. A certain microcontroller ISP interface is UART (Universal Asynchronous Receiver/Transmitter). This microcontroller is a part of a bigger embedded system in which UART interface is not available, the available interface is SPI (Serial Peripheral Interface) only. In this paper, a custom in-system firmware upgrade approach using SPI will be described for the MSP430 Texas Instrumentations Microcontrollers family.
