Re: VS1053 in encoder mode - enter PCM 16 bit mono 8 kHz

Hello, Support! Thank you for your help! I see no more reason to look for a lot of vs1063 to vs1053 suit my purposes! Sorry, what Panu's patches? I mean what about Panu patches wrote above...... David Rowe (creator of Codec2) made draft-version of Codec2 at 700 bit/s, which sounds as 1300 bps! See s...

Re: VS1053 in encoder mode - enter PCM 16 bit mono 8 kHz

Hello Henrik!

I saw datasheet for VS1053 - there are ADPCM and Ogg Vorbis recording. No PCM recording.
Only with Panu's patches, but samplerate 8kHz profile does not exist.

Is really VS1053 builtin-firmware can encode RAW PCM (not ADPCM !) 16 bits and 8 kHz samplerate?

Re: VS1063a: How to connect mini speaker in mono mode?

Hello users and support! I wrote some firmware for this device. There are some results presented: Transmitter output power: +20 dBm (100 mW), Frequency 430.7 MHz, antenna: full L/4-wave 1) MP3 En-Coder 32 kbps: receiver sensetivity -113 dBm, stable Link distance 400 m - very purely :( 2) MELP 2400 b...

Re: VS1053 in encoder mode - enter PCM 16 bit mono 8 kHz

Hello, Panu! Meaning, maybe that software could be modified to support 8 kHz. How I can enter 8 kHz samplerate to 48 khz or 24 kHz profiles? Hmm, do you see some other firmware which would be close to your need? I saw "vs1053-vs1063-pcm-recorder-130.zip" and decided, that this program is suitable fo...

Re: VS1053 in encoder mode - enter PCM 16 bit mono 8 kHz

Hello, Panu! I read "VS1053B / VS1063A WAV PCM RECORDER" article in pdf-file, there is 48 kHz and 24 kHz profiles. I need in 8 kHz profile. What about it? Need full configuration : PCM, 16 bit, 1 channel(Microphone), 8 kHz samplerate. Or, how I can enter 8 kHz PCM recording mode for this plugin/appl...

VS1053 in encoder mode - enter PCM 16 bit mono 8 kHz

Hello, Support and another users! Happy New Year! :) Considering that the VS1063 chip is very rare, and its previous version of VS1053 more common and available for radio amateurs. Please enter the chip VS1053 encoder mode PCM 1 channel 16 bits at a sampling rate of 8 kHz. This is a very useful appl...

Re: VS1063a: How to connect mini speaker in mono mode?

Hello, Panu. At the expense of the simplest example in the source code - I'll think about it. This is multifunction device - for example, VS1063 codecs can be used without the STM32 DSP features (as vocoder). In this case receiver sensitivity will be worse, because it is requires more bitrate for VS...

Re: VS1063a: How to connect mini speaker in mono mode?

Any chance for you to publish the source code? ;) Hello, Panu. I think it is not necessary to untie the hands of idlers. All chips available documentation. However, I alone have spent a lot of man-hours and money in the creation of this project. Repeat the device, I think, perhaps, my firmware or w...

Re: VS1063a: How to connect mini speaker in mono mode?

Hello!

I developed project with VS1063A chip - Low Power Walkie-Talkie at 4xx MHz.
It works nice, thank support for help and VS10xx chips! :D

In current mode - vocoder 2400 bps (STM32) + PCM FIFO (VS1063).

Re: VS1063a issue beetween ENCODE and DECODE states

Hello, Pasi!

I know about "0xFEFE". It would be great even if the power supply to the ADC and DAC were separated.

In next chip it is planned, or not? And remove ADC-swap hardware issue?
