Hi every body,
I wish you a happy new year
I develop a command bord around the LPC1788 on which I have used many peripherals com. On of theme is UART.
On this UART user will use an RS485 implementation (Of course I added a RS485 transceivers). Regarding to the software, I wish to use the NXP Implementation of the RS485 (RS485CTRL, RS485DLY, RS485ADRMATCH).
After reading the related section on the UM, I am confused on how to use the RS485 filtering address. And it seems little bit hard to find a Serial Terminal to test the communication because of: the setting to '1' of the parity bit of address (set to '0' for data)
In addition if I have to use a parity checking at receive and send (odd or even) how the NXP-RS485 will differentiate the address from data?
In my application, it will be useful to associate the first byte to address and the rest is always data. Can I use this kind of checking address mechanism (Of course with no software checking)
