大家好。
我设计的
电路测试/编程设备生产并考虑连接SWD接口和I2C。
DUT(测试设备)使用I2C进行所有
通信。
所以我需要使用I2C从测试主机(PC使用Python)执行测试命令。
由于miniprog3可以设置为一个I2C桥以及作为一个程序员,我considerint线的I2C引脚与SWD引脚在编程/测试。
有没有人成功地做到了这一点?
是否有任何不良影响的SWD接口,I2C通信运行?
我假设SWD接口直到复位引脚被拉和SWD初始化是在“待机”模式…这意味着我可以混合这些信号。
欢迎任何想法!
当做,

Hi all.
I'm designing produc
tion in-circuit test/programming fixtures and considering to connect SWD interface together with I2C.
The DUT (Device Under Test) uses I2C for all communication.
So I need to use I2C from test host (PC using Python) to execute test commands.
Since the MiniProg3 can be set up as an I2C bridge as well as a programmer, I'm considerint to wire I2C pins together with SWD pins while programming/testing.
Did anyone out there already do this successfully?
Could there be any adverse effects on the SWD interface while I2C communication is running?
I'm assuming SWD interface is in "standby" mode until reset pin is pulled and SWD initialized... which means I could mix these signals.
Any ideas are welcome!

Michel
