Shift register SPI control
-
Hi,
I am trying to control a integrated circuit, similar to SN74HC595, using an omega2, based on the spi. Is there any solution to send data via SPI, but without sending the address?

Four-wire SPI Slaves do not need (do not use) a unique address.

The reference is to a register address within the chip.
Onion's SPI API improperly assumes that all SPI devices have such a concept - but this device does not.
I believe there have been some past threads on the SPI address issue.

@Denis-Ilie-Ablachim why don't you give us the part number of the ic you are using? Would bit banging (on some other GPIOs) be a solution?
