I have an STM32F765 Master attached to 7 STM32F411 Slave processors on Half Duplex RS485 bus. The slave processors are in Address Mark mode. They are normally MUTE, until they receive their matching address.
Is it true that the BREAK FRAME gets recognized only by the slave processor that is not in MUTE ?
If the above is true, is there any other way to send a Frame on HALF DUPLEX RS485 bus that is recognized by all slave processor. The purpose for this is to capture data from sensors attached to slave processors simultaneously.
