Part Number: USB2ANY
Other Parts Discussed in Thread: LMX2594

Hi Team,

I have following 12 bytes data to send with USB2ANY to LMX device.

Due to its special data format, it have to group each line of data with same packet (CS LOW).

Otherwise, it won't be a success write.

Can USB2ANY do this? I cannot find a way so far...

Thanks.

4B (register) 09 00 (data)

2B (register) 03 AC (data)

24 (register) 00 2F (data)

00 (register) 25 1C (data)

Hi Andrew,

Can you specify exactly which device you are using the USB2ANY with?

Hi Andrew,

You could try using a GPIO pin for the CSB instead of the dedicated chip select pin. Then you could write all four registers as separate transactions, and use the GPIO pin to manually latch the write when you are done.
