自己有一个东东，有9个引脚，用了7个，每个引脚功能描述如下
1：N_Boot_link ，Enables field programming of internal processor
5V wrt DGND, active low signal ,0V when in use.
2: + link_Ser_out,RS422 Signal,+5V,0V
3: - link_Ser_out,RS422 Signal,+5V,0V
4: +link_Ser_In ,RS422 Signal,+5V,0V
5: -link_Ser_In ,RS422 Signal,+5V,0V
6: N_Wdogdis ,Stops Watchdog from timing out during field programming of the internal processor,5V wrt DGND,active Low signal,0V when in use
7: Link_Reset,Reset processor, 0V,active high signal ,5V wrt DGND when in use
我现在想用一个合适的读写电路和软件，对这个东东内部的程序进行读写，在此求助各位高手支招。谢谢 |
