A developer's note on enabling BLE Transparent Transmission for the BT401 Dual-Mode Audio Bluetooth module.

Data Flow:

Your MCU can send any data (non-AT-commands) over UART, and it will be transparently transmitted via BLE.

Any data sent from a mobile app is forwarded directly to your MCU, The module itself won't process it, giving your application full control.

Exploring the KT142A voice chip? Here’s a robust guide for developers:

🔹 Audio Prep: Optimize MP3s (remove silent segments, 16kHz recommended)
🔹 Hardware: 3V-5.2V power, PWM/DAC options, BUSY pin diagnostics
🔹 Debugging: Fix playback truncation (reduce amp capacitor to 10nF)

Real-world example: Bus announcements & Community access control

I screwed up so hard.

Does anyone in #EmbeddedDev have the document "Programming Sharp Memory LCDs"? It was a document they themselves created for the obvious purpose and no longer host.

I thought I was keeping all my datasheets locally but I can't find these ones.

I've just pushed an update to my #blog!
In this post:

• Get yourself some updates regarding the state of PETI, my ongoing virtual pet development project!
• Patch rants with unusual brevity about decisions made by major corporations.
• True facts about Patch's Starfield, Fallout 4, and Dwarf Fortress playtime statistics in Steam.

So among the things I did yesterday that I was putting off for fear of their complexity, but which later turned out to be quite straightforward, was writing a custom export module for the font editing tool we've been using for PETI. This new exporter lets anyone use fontedit to spit out a font in a much more standard format, which can then be edited with any additional tooling of their choice which supports it.

It's an unfortunate bit of yak-shaving, but it should get me unblocked on creating the new glyphs I needed to finish the evolution features and get the next update out to you guys much more quickly.
