Right now, we use interrupts for SPI reads/writes in performance critical parts of lora transmission. This is fine for now, but adds CPU overhead to large/frequent transmissions.
Describe the solution you'd like
We should switch to DMA for our SPI reads/writes to offload our CPU during transfers.
Describe alternatives you've considered
