摘要
针对水声Modem耐压舱体中MSP430单片机需要程序更新的需求,为改进传统更新程序时需打开耐压舱体,通过JTAG更新程序操作复杂的问题,本文研究了基于MSP430FR5969的串口程序加载升级设计方法。通过实验测试,证明此方法稳定、可靠,简化了以往仿真器更新MSP430单片机程序的复杂流程,并大大减少了更新程序需要的引脚数量,实现方便快捷的更新水声Modem中的MSP430单片机程序。
Aiming at the demand for updating MSP430 SCM program in underwater acoustic modem pressure-tight cabin, in order to improve the condition that we need to open the pressure-tight cabin to update the traditional program, and solve the problem of complex updating with JTAG, this article researches the design procedures of UART program loading and upgrading which is based on MSP430FR5969.Tests prove that it＇s a stable and reliable method, which simplifies the complex flow of previous emulators when updating MSP430 SCM program. What＇s more, it decreases significantly the quantity of pins which are necessary for the updating program.The method realizes a convenient and fast way to update MSP430 SCM program in underwater acoustic modem.
