Hi,
Some questions about USS connect to TDA4AL in APA application.
USS: Ultrasonic Senor, or sonic radar, or sonar.
USS is used in Auto Parking assistant.
1, Which interface of USS does TI recommend? LIN? CAN? DSI3? IO? I find some LIN interface in SOM and EVM of TDA4AL, are them prepared for USS?
2, If we use DSI3 USS, How does TDA4AL connect to three DSI3 master(elmos E521.42A, SPI interface)? using three SPI to connect to three E521.42A? or using one SPI and three CS to connect to three E521.42A? Is SPI difficult to use?
3, If we use IO USS, we need PWM or TIMER_IO to be TX, we need GPIO+DMA to be RX. Is PWM difficult to use? Is Timer_IO difficult to use? Is GPIO+DMA difficult to use?
4, If we use IO USS, we need 12 TX and 12 RX in TDA4AL. TDA4AL does not have enough pin, Could you give some suggestion?
5, Does USS connect to main domain or mcu domain? which domain is better?
Thanks.
