    • Started researching more about I2S Audio
      • Inter-IC Sound
      • Standardized by Philips Semiconductor which is now NXP
      • One way to represent PCM (Pulse Code Modulation) Audio
      • TAS5731
  • Stephen 
    • Synthesizer Update 
      • Got the envelope working.
      • Envelope controls the volume and signal amplitude.
      • There was a hardware bug in that the envelope turned on before the frequency changed to the next note. 
        • Stephen fixed it in software by adding a small 10ms delay before opening the envelope.
  • Pick Of the Week (POW)

      • 1. “RGB port refresh rate increased from 400Hz to 2000Hz, there’s LOW Frame Frequency and No Flicker appear in HD Video Camera, it improves excellent Large-Screen display effect.”
      • 2. “RGB port current-output reduced from 17.5mA to 16.5mA, it can’t be recognized by naked eyes and won’t affect the mixed OLDs & NEWs. However, it’s recommended to separate these old & new chips if your demand performance-critical.”
      • 3. “Old & New chips go all the way in PINs, application circuits, operating voltage, and PCB drawings, and the software is also fully compatible.”
      • 4. “Old & New chips are exactly the same as in Timing, Data transmission and Data structure. However, the Reset Time increased from >50us to >280us. It won’t cause wrong reset while interruption, and what’s more, it supports the lower frequency and inexpensive MCU. When the “Reset Time<280us”, don’t mixed up and kindly please make necessary amends.”
