History

Dario Nieuwenhuis 6a4ac5bd60 Add collapse_debuginfo to fmt.rs macros. This makes location info in defmt logs point to the code calling the macro, instead of always to fmt.rs as before. Fix works with nightlies starting with today's, and stable 1.81+.		2024-06-17 01:38:57 +02:00

README.md

cyw43

Rust 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).
AP mode (creating an AP)
Scanning
Sending and receiving Ethernet frames.
Using the default MAC address.
embassy-net integration.
RP2040 PIO driver for the nonstandard half-duplex SPI used in the Pico W.
Using IRQ for device events
GPIO support (for LED on the Pico W)

TODO:

Setting a custom MAC address.
Bus sleep (for power consumption optimization)

Running the examples

Install probe-rs following the instructions at https://probe.rs.
cd examples/rp

Example 1: Scan the wifi stations

cargo run --release --bin wifi_scan

Example 2: Create an access point (IP and credentials in the code)

cargo run --release --bin wifi_ap_tcp_server

Example 3: Connect to an existing network and create a server

cargo run --release --bin wifi_tcp_server

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

This 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.
