Teuta DT-1 — MFi Auth Hypothesis: Dual 30-Pin Passthrough for Digital USB Audio

Project Summary

Teuta DT-1 is an open-hardware iPod digital transport. Goal: extract Red Book digital audio (16-bit/44.1kHz PCM) from an iPod Classic via its 30-pin male dock port, route it through a hi-fi DAC (DACBerry ONE+ — WM8804 + PCM5142), output analog.

• MCU: STM32F405RGT6 (WeAct Core Board)
• Audio path: iPod → USB UAC1 (pins 15/16) → STM32 → I²S DMA → DACBerry ONE+ → analog out
• Control path: iAP over USB HID + serial UART fallback (pins 12/13)
• Power: USB-C PD via RotoPD (AP33772S)

PowerShell execute command with arguments safely

In my opinion this is the best way for executing external commands from PowerShell with arguments in a safe manner - via the use of an array to hold the arguments.

Consider this one a PowerShell gem to keep in the toolbox.

Note

The example below makes use of EchoArgs.exe - a small utility that simply echoes back arguments passed to it. Utility is part of the PowerShell Community Extensions, or the exe alone can be downloaded at https://ss64.com/ps/EchoArgs.exe.

Example

compilerexe

#include <Wire.h>    
 
#define disk1 0x50    //Address of 24LC256 eeprom chip
 
void setup(void)
{
  Serial.begin(9600);
  Wire.begin();  
 
  unsigned int address = 0;
