Full duplex SPI?

@milan_va

The second problem is a bigger one: there’s NO fullduplex mode. Using the 4-wire interface, it should be possible to write and read at the same time, but there’s no adl_busFullDuplexTransfer() function! Some devices use this full-duplex mode, but it just CANNOT be implemented in Wavecom.

Yes, that does appear to be the case!

Does anyone know if this functionality is going to be added, and when?

Still, apparently, not there: Can Open-AT do *Full* Duplex SPI yet?

I see a driver for a M93Cx6 eeprom memory which is a full duplex part in \samples\libraries\src\drv_m93cx6.c - problem is not any hint as to how it was hooked up in hardware! Since I don’t have the source for the spibuss functions - I don’t know. Any help would be appreciated as I am trying to complete a hardware design.

Did you manage to get around this?
