Mark, How do I load audio onto these and program the macros? i.e. what hardware do I need? It seems like they are programmed using SPI via the nuvoton USB dongle, is that correct?
The most likely other alternative I would go for would be some variation of this https://circuitdigest.com/microcontroller-projects/arduino-audio-music-player though I would want avoid using a SD card module and build it directly on to my circuit board instead. I will probably try both. - Paul From: Mark Moulding Sent: Saturday, September 29, 2018 6:58 PM To: neonixie-l Subject: [neonixie-l] Re: Adding audio clips to a clock... I've used the ISD chips quite a bit, including building them into products, and I've generally had very good experiences with them. They've gotten considerably cheaper over the years, and they're available in more high-volume packages than they used to be, but they're still fundamentally the same chip. Sure, if I wanted to have a long recording time, or DC-quality audio, I'd go for a flash-based digital solution. But for things like clock chimes in Nixie clocks (short duration, limited frequency response that actually can make the chime sound better, and very limited production quantities), they're a really good fit. There's essentially no programming needed to use them, and although I now have a semi-permanent breadboard jig to load the audio, for a long time I just used a few clip leads. So far, I've noticed no sound degradation even in devices that are nearly 20 years old, which tends to support their claimed 100-year retention time. ~~ Mark Moulding -- You received this message because you are subscribed to a topic in the Google Groups "neonixie-l" group.
