That will work. If you did want to use THVD1450 for some reason, you could tie DE to VCC and /RE to GND and it would be equivalent.
Will this node ever need to receive data from other nodes, though? If so, then you might want to revise your approach…
Hi Kai,
TI does not have a transceiver which is directly compatible, although similar behavior can be achieved with a standard RS-485 transceiver by implementing failsafe termination (A pin pulled high, B pin pulled low), tying the D input low, and…
Hello Shu-Cheng,
There are a couple of different approaches for automatically controlling the direction of the RS-485 transceiver. The MAX13487 device implements this by only actively driving the low signal level and going high-Z for high levels (making…
Hi Rohit,
This circuit basically makes it so the RS-485 transceiver has two states:
- D signal low: driver is active and drives a negative differential voltage onto the bus (to be interpreted as a logic "low" level by an RS-485 receiver).
- D…
Part Number: TMS320F28069M Hello,
We are working on a project that requires SCI bootloading for the F28069M. The customer has specified half duplex UART for the project.
Because we will be running out of SCI mode from the ROM code, we won't have direct…
