Re: WWVB timecode from blue pill

One other project I had considered was converting a really cheap AM radio from fleabay to pick up the MSF signal on 60kHz , and then use the audio output from that to feed a micro-controller. MSF, DCF77 and a lot of others radio stations (mostly european radios, I believe) can be heard here http://...

Re: WWVB timecode from blue pill

I have some radio controlled clock working using DCF77 ( one of then is multistandard) that works at 77,5 kHz.

I too live a bit too far so some of them works perfectly, some others need to be in the north part of my house.

Re: L476RG audio recorder

It records a Wav on a SD, you don't need Arduino to hear it.

Re: L476RG audio recorder

The TMRpcm example uses 16KHz sample rate on an Atmega328p. The quality is still poor, maybe because of noise, bad analogic circuit or other reasons.

Re: L476RG audio recorder

There is an example how to use it. This one. Never tested on a STM32. Remember that you have to use a MIC with a decent amplifier like the cheap ones that use a MAX amplifier otherwise you will get only noise. Using MAX you will get noise but not ONLY noise! /* WavRecAndPlay was Recording example of...

Re: New CPU+GPU+MPU chips from ST!

But what prevents them from moving away from Broadcom is not only history, but what makes the Rpi such a cash machine: the exclusivity they have on the CPU and the lock with the GPU blob. Otherwise, they would have been cloned by Chinese manufacturers a long time ago. The GPU blob should be inside ...

Sheepdoll, you forgot Mt Etna! It's about 3 days that is emitting ash, there was others ash emissions starting from the small eruption on December 24 ( a small dike intrusion visible on SAR images) and small activity on the summit craters from August 2018 small eruption. I took this today during a p...
