optimizing DMA configuration call

3.2.0

tried reducing dma reconfiguration over head

Adding DMA to replace memcpy

3.1.0

starting to replace memcpy with DMA

Started trying DMA optimizations

In this release, we have tried to expand the eth callback function to disassociate the inline calling of the usb_tx function with DMA. No performance boost was observed.

removed download packet cap

Updated the CherryUSB lib

Updated the CherryUSB lib and moved the rp2040/

added support for the latest CherryUSB library by matching the function calls

Ports labeled for easy access

When we try to list the serial ports all ports are mentioned clearly for easy access

2.0.0

1. A web page added (index.html) to control the PicoPiFi
2. Open the html page connect to the first CDC port
3. Currently reserved CDC ports are working as echo ports
4. No hard Coded WIFI Creds

Stability improved with pbuf_take instead of memcpy

Default ssid and password are 'ssid' and 'password', respectively which the firmware will try to connect once uploaded to the pi pico w board.

Recompile with network relative ssid and password required to connect to different network.

pico-sdk lib folder updated to the following submodules and tested:-

Removed the buggy code which crashed the driver

Steps to install on the Raspberry Pi Pico W :-

Make use of the default WIFI settings:-

Set the WIFI network ssid to "ssid" and WIFI password to "password" (it might disconnect all other clients in the WIFI network is also insecure way)
set the pi Pico w in uf2 receive mode by pressing the onboard boot button and plunging in the pi Pico
copy the "pico_webserver.uf2" binary to the pi Pico w

Make Use of existing WIFI settings:-

change the ssid and password passed in the function cyw43_arch_wifi_connect_async as 1st and 2nd arguments respectively
compile the project as described in the readme which will create a custom "pico_webserver.uf2" with your WIFI settings
set the pi Pico w in uf2 receive mode by pressing the onboard boot button and plunging in the pi Pico
copy the "pico_webserver.uf2" binary to the pi Pico w

Debug Tips:-

Goto Control Panel -> Network and Internet -> Network Connections for a new rndis ethernet network adapter created
open task manager to check if traffic is flowing for the rndis ethernet network adapter
If the traffic stops instead of removing and replugging the pi pico yu can disable and enable the rndis ethernet network adapter found in the step 1

ToDO :-

improve speed and bandwidth
find a way to dynamically updated the ssid and password for the firmware
