TI中文支持网Part Number:EMB1428Q
hi，
目前在单独使用emb1428时，在while中调用开关闭合的函数接口，可以正常控制开关的开闭，但是把接口放到1ms_task()任务里运行，或者2ms. 10ms. 100ms中，都不能控制开关闭合，这是为什么呀？
Star Xu：
您好, the EMB1428 device is intended as a tandem device with the EMB1499 so we have limited support available for this topic. Can you identify if it is possible to follow our reference material for using the EMB1499?

您好，
我这边硬件同事没有使用1499芯片，DONE脚和EN脚是做了一个反向，DIR和DIR_RT做了一个反向，反向的意思是当EN脚为高时DONE为低，这样做能否达到1499的作用呢？

Thanks for your reply，
By the way, two EMB1428 are used in this design, without the use of a 1499 chip. The following designs are made for the seven pins:DIR and DIR_ RT has made a reverse circuit, and DONE and EN pins have also made a reverse circuit,Three FAULT pins are designed as interlocking functions for two EMB1428 chips. Interlocking is for safety reasons. When one EMB1428 is closing a certain channel, the switch controlled by the other 1428 must be fully open. The FAULT0 pin is controlled through GPIO, and the FAULT1 and 2 are connected to GND. This design currently cannot achieve the effect of two chips interlocking under testing.XU ,Please give me some guidance, thank you
