Hi Team,

The method that the customer using now is using delay in program and selecting chip after sent complete by using judgment statement.

I apologize for this vague expression. I guess conditional statements(like if{}) is the more precise expression.

The customer achieve chip selection by using customer software now. He want to know is there any hardware solution to achieve this function?

Thanks & Regards,

Yale,

I did look around but could not find any hardware solution for it. There are other serial communication like SPI which have a chip select line but not sure for RS485.

Best Regards
