Hi,
I'm sorry, maybe just my own self dun understand.
I'm now not use full duplex already. The reason why i need to use before is because i need to send control signal to control my car and the data at the car side need to send back to my side and display. so i need both ways communication. so i used hardware usart to do this since the datasheet say it support.
Hmmm, Nigel, May i know even let say it is not intended used in full duplex communication. But just when a 315Mhz and 433Mhz RF module are turn on together, but they are control different devices...but don't they affect each others? Just like in my case, now they are independence at all... no full duplex but juz MCU1 communicate with MCU2 using 315MHz pairs and MCU3 communicate with MCU4 using 433MHz pairs.
Hmmm...i'm sorry, i juz trying to describe my situation...i really wonder why they affect to each other since they are independence.
