__CAUTION: Sending a LoRa Message on PineDio USB (not BL602) above 29 bytes will cause message corruption!__
__CAUTION: Receiving a LoRa Message on PineDio USB (not BL602) above 28 bytes will cause message corruption!__
(CH341 SPI seems to have trouble transferring a block of 32 bytes)
For BL602 / BL604: To add this driver to an existing BL602 / BL604 project:
```bash
cd bl_iot_sdk/components/3rdparty
git submodule add https://github.com/lupyuen/lora-sx1262
```
Ported from Semtech's Reference Implementation of SX1262 Driver...

# Build PineDio USB Driver
To build PineDio USB Driver on Pinebook Pro Manjaro Arm64...
```bash
## Install DKMS
sudo pacman -Syu dkms base-devel --needed
## Install Kernel Headers for Manjaro: https://linuxconfig.org/manjaro-linux-kernel-headers-installation
uname -r
## Should show "5.14.12-1-MANJARO-ARM" or similar
sudo pacman -S linux-headers
pacman -Q | grep headers
## Should show "linux-headers 5.14.12-1" or similar
## Reboot to be safe
sudo reboot now
## Install CH341 SPI Driver
git clone https://github.com/rogerjames99/spi-ch341-usb.git
pushd spi-ch341-usb
## TODO: Edit Makefile and change...
## KERNEL_DIR = /usr/src/linux-headers-$(KVERSION)/
## To...
## KERNEL_DIR = /lib/modules/$(KVERSION)/build
make
sudo make install
popd
## Unload the module ch341 if it has been automatically loaded
lsmod | grep ch341
sudo rmmod ch341
## Load the new module
sudo modprobe spi-ch341-usb
## Plug in PineDio USB and check that the module has been correctly loaded.
## See dmesg Log below. This needs to be checked every time we reboot
## our computer and when we plug in PineDio USB.
dmesg
## If we see "spi_ch341_usb: loading out-of-tree module taints kernel",
## Unplug PineDio USB, run "sudo rmmod ch341", plug in PineDio USB again
## and recheck dmesg.
## Download PineDio USB Driver
git clone --recursive https://github.com/lupyuen/lora-sx1262
cd lora-sx1262
## TODO: Edit src/main.c and uncomment READ_REGISTERS, SEND_MESSAGE or RECEIVE_MESSAGE.
## See "PineDio USB Operations" below
## Build PineDio USB Driver
make
## Run PineDio USB Driver Demo.
## See Output Log below.
sudo ./lora-sx1262
```

# PineDio USB Operations
The PineDio USB Demo supports 3 operations...
1. Read SX1262 Registers:
Edit [`src/main.c`](src/main.c) and uncomment...
```c
#define READ_REGISTERS
```
(See the Read Register Log below)
1. Send LoRa Message:
Edit [`src/main.c`](src/main.c) and uncomment...
```c
#define SEND_MESSAGE
```
(See the Send Message Log below)
1. Receive LoRa Message:
Edit [`src/main.c`](src/main.c) and uncomment...
```c
#define RECEIVE_MESSAGE
```
(See the Receive Message Log below)
Note that the CH341 GPIO programming is incomplete. We need to...
1. Init the GPIO Pins: `SX126xIoInit`
[src/sx126x-linux.c#L65-L77](src/sx126x-linux.c#L65-L77)
1. Register GPIO Interrupt Handler for DIO1: `SX126xIoIrqInit`
[src/sx126x-linux.c#L79-L91](src/sx126x-linux.c#L79-L91)
1. Reset SX1262 via GPIO: `SX126xReset`
(For now we reset SX1262 by manually unplugging PineDio USB)
[src/sx126x-linux.c#L149-L169](src/sx126x-linux.c#L149-L169)
1. Check SX1262 Busy State via GPIO: `SX126xWaitOnBusy`
(For now we sleep 10 milliseconds)
[src/sx126x-linux.c#L171-L182](src/sx126x-linux.c#L171-L182)
1. Get DIO1 Pin State: `SX126xGetDio1PinState`
[src/sx126x-linux.c#L337-L344](src/sx126x-linux.c#L337-L344)
We also need Background Threads to receive LoRa Messages in the background...
[src/main.c#L355-L408](src/main.c#L355-L408)

When we run the [`sdk_app_lora`](https://github.com/lupyuen/bl_iot_sdk/tree/tsen/customer_app/sdk_app_lora) firmware on PineDio Stack BL604, WisBlock receives the 64-byte message OK.
But 64-byte messages sent by PineDio USB are consistently garbled when received by WisBlock.

It means the older CH341 Non-SPI Driver has been loaded.
To fix this...
1. Unplug PineDio USB
1. Enter...
```bash
sudo rmmod ch341
```
1. Plug in PineDio USB
1. Enter...
```bash
dmesg
```
And recheck the messages.
