Are there any good examples using RawSerial for non-blocking UART with DMA I am using the LPC4088 QSB

How do you use the following Public Member Functions?

set_dma_usage_tx write attach

Thanks, Pavel

That is only supported by a very few devices, and for now it does not seem like others are going to support it.

You can have a look at https://developer.mbed.org/cookbook/MODSERIAL and/or https://developer.mbed.org/users/Sissors/code/SimpleDMA/. Both of these are not suitable for the LPC4088, however they both support the LPC1768, and the LPC4088 is very similar.
