This commit adds the allow(unused) attribute to functions and constants that are not currently used. There is one warning remaining but https://github.com/embassy-rs/cyw43/pull/23 attempts to address that one. The constants have been moved into a module to allow the attribute to be applied to the module as a whole. The motivation for this is that it will hopefully make it easier to spot new warnings that might be introduced by new, or updated code.
cyw43
WIP driver for the CYW43439 wifi chip, used in the Raspberry Pi Pico W. Implementation based on Infineon/wifi-host-driver.
Current status
Working:
- Station mode (joining an AP).
- Sending and receiving Ethernet frames.
- Using the default MAC address.
embassy-netintegration.
TODO:
- AP mode (creating an AP)
- GPIO support (used for the Pico W LED)
- Scanning
- Setting a custom MAC address.
- RP2040 PIO driver for the nonstandard half-duplex SPI used in the Pico W. Probably porting this. (Currently bitbanging is used).
- Using the IRQ pin instead of polling the bus.
- Bus sleep (unclear what the benefit is. Is it needed for IRQs? or is it just power consumption optimization?)
Running the example
cargo install probe-runcd examples/rpi-pico-wWIFI_NETWORK=MyWifiNetwork WIFI_PASSWORD=MyWifiPassword cargo run --release
After a few seconds, you should see that DHCP picks up an IP address like this
11.944489 DEBUG Acquired IP configuration:
11.944517 DEBUG IP address: 192.168.0.250/24
11.944620 DEBUG Default gateway: 192.168.0.33
11.944722 DEBUG DNS server 0: 192.168.0.33
The example implements a TCP echo server on port 1234. You can try connecting to it with:
nc 192.168.0.250 1234
Send it some data, you should see it echoed back and printed in the firmware's logs.
