#RISCV #PineCone #BL602 @PINE64 connected to #LoRa SX1276 / RF96 Transceiver ... Including pins DIO0 to DIO3

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276.h#L24-L39

@PawelK Erm I'm still making changes to the driver and I'm writing an article about this driver ... Maybe we hold off the changes till I'm done?

@PawelK Original LoRa SX1276 Driver for Mynewt OS:

https://github.com/apache/mynewt-core/blob/master/hw/drivers/lora/sx1276/src/sx1276.c

Ported to BL602:

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/sx1276.c#L265-L307

The original code calls "hal_spi_tx_val", which is a Mynewt SPI Function that transfers 1 byte over SPI. It's clearly not designed for DMA.
