Discussion - EVE / REG_CMDB_WRITE bulk transfer
« on: August 09, 2021, 01:34:01 PM »
Hello!
I've used EVE 1 and 2 in projects before. Now I'd like to take advantage of REG_CMDB_WRITE command.
If understood correctly, REG_CMDB_WRITE takes one 32-bit command. Do I have to send a total of 7 bytes (3 byte address + 4 byte data) over SPI per 32 bit display list command?
Or is there a way to send multiple commands at once as a real bulk transfer? Something like: 3 byte address -> 32 bit command -> 32 bit command -> 32 bit command ...
The address overhead seems to high when sending big amounts of data.
Best regards,
Paul
