Other Parts Discussed in Thread: TMS320F28386D
Hello,
We are using the TL16C750E in RS485 mode in our design, the schematic is the following:
The clock is set at 25MHz and we are connected to the EMIF bus of a TMS320F28386D.
Transmitting data on the bus works perfectly, however we can't seem to be able to receive data.
We tracked down the received data down to the component RX pin and the signal seems ok to us:
These screenshots are showing data transmission of 16 bytes at 250kbit/s (I think we are sending 0xAA, 0x01, 0x02, ...).
The registers configuration of the component is the following:
- EFR: 0x10
- FCR: 0x07
- LCR: 0x0B
- MCR: 0x00
- AFR: 0xA4
- DLL: 0x06
- DLH: 0x00
- DLF: 0x10
We have tried with internal loopback and we are receiving data but from the outside it doesn't seem to want to work.
Any idea/hint ?
Best regards,
Clément
