Hi,
I'm working on a project with R7FA4M2AD3CFM, we are setting up Modbus RTU communication on uart0, FSP4.0.
Here is the problem, no matter what stop bits is configured from the uart property, there is always one more bit added to actual communication for Tx(read from actual communication RS485 bus).
I understand from the user manual about stop bit for Rx is fine. Just want to know for Tx if this is the expected behavior.
Thanks.
Hello Sdman,
Stop bit is used both on transmission and reception mode and also 1 or 2 bits can be used to declare the stop condition.

Hi AL_Renesas,
Thanks for your reply, the problem is, when I set the stop bit as 1, during the transmission I get 2 stop bits, and when I set the stop bit to be 2, actually it is 3 stop bits.
I was expecting to see the stop bits number matches with the configuration, however it is always one more bit than the setting.
Can you share a demo project to check it in detail?
