This document covers a solution that might improve the stability of USB4VC.
|
|
|
|
## Overview
|
|
|
|
A `BUSY` signal is added, to prevent Raspberry Pi from sending data when Protocol Card is talking to the computer.
|
|
|
|
This, along with a firmware update, should improve stability and reduce stuck keys or glitches.
|
|
|
|
## Instructions
|
|
|
|
### Solder a New Wire
|
|
|
|
Solder a wire between the pins at **`F1` and `second row of right most column`**. See photo:
|
|
|
|
|
|
|
|
|
|
|
|
Make sure **there are no short circuits**.
|
|
|
|
### Software Update
|
|
|
|
Connect RPi to internet. You can [set up WiFi](https://github.com/dekuNukem/USB4VC/blob/master/getting_started.md#optional-set-up-wifi), or plug in an Ethernet cable.
|
|
|
|
Then simply select Internet Update in main menu. It will update RPi code and P-Card firmware to latest version.
|
|
|
|
|
|
|
|
Confirm on the second screen that both PB and RPi version are **above 0.3.0**.
|
|
|
|
|

|
### Try it Out!
