The RP6502 Interface Adapter W (RIA W) is a Raspberry Pi Pico 2 W with RP6502-RIA-W firmware. The RIA W provides everythiung the :doc:`ria` does along with the wireless services described in this document.

2. WiFi Setup
15
+
=============
16
+
17
+
The WiFi hardware is an Infineon CYW43439 supporting Wi-Fi 4 (802.11n). Configuration is done from the console.
18
+
19
+
`SET RF (0|1)` is used to disable all radios without clearing any other settings. It defaults to 1 (enabled).
20
+
21
+
`SET RFCC (cc|-)` can be used to improve WiFi performance. `help set rfcc` will show the supported country codes. Clearing with "-" will use the Worldwide default.
22
+
23
+
`SET SSID (ssid|-)` sets the name of your WiFi network, also called the Service Set Identifier.
24
+
25
+
`SET PASS (pass|-)` sets the password for your WiFi network, if you have one.
26
+
27
+
You can check WiFi status with the `status` command.
28
+
29
+
3. Network Time Protocol
30
+
========================
31
+
32
+
The real time clock will automatically update its time whenever connected to the internet.You can check NTP status with the `status` command.
33
+
34
+
If you prefer local time instead of UTC, set the TZ. Always remember `help set tz` is there for you. Once set, it will adjust for daylight savings time if your locale uses it.
35
+
36
+
Once your Wifi and time zone are set, you can forget about time. Drift isn't a problem and there's no battery to replace.

The RP6502 Video Graphics Array is a Raspberry Pi Pico with RP6502-VGA firmware. Its primary data connection is to a :doc:`ria` over a 5-wire PIX bus. More than one VGA module can be put on a PIX bus. Note that all VGA modules share the same 64K of XRAM and only one module can generate frame numbers and vsync interrupts.
