Hi everyone, a lot of time since my last post on this forum and noticed many things has changed, in better. I want to spread (spam) my boosterpack project, Aida DSP boosterpack It's a boosterpack dedicated for audio and for now available only for TivaC. With this boosterpack you can do 24bit/192kHz pristine audio elaboration, since it has a DSP on it, so while this DSP is occupied with audio elaboration you can do a lot of things with your mcu: read audio signal envelope, manage a user interface and -why not?- a complete keyboard or a rich display, ecc. http://www.aidads

Hello chaps! What I'm basically trying to do is record as much audio as I can (about 30k samples from a line-in source) then dump it all over serial. I'd like to use the Audio Booster pack (http://www.ti.com/tool/cc3200audboost) which does all the codec magic for me. But - I can't get it to work with energia. (to be honest, the documentation for how to actually use the thing is pretty poor regardless of programming tool...) I did my best to duplicate the needed parts of the (also terrible) Wifi audio demo app from TI's official SDK but to no avail. Has anyone had success at

I'm creating a kind of Yak Bak for a project I'm working on for my small son. The basic idea is that I'll start recording audio when one button is pressed, and start playing it back when another has been pressed. My initial plan was to just use something like an msp430g2553's onboard ADC to sample a microphone, and play it back using a PWM output. From what I can tell, I should sample my audio at 8 kHz to satisfy the Nyquist theorem. It looks like an msp430g2553 (and all comparable processors I've looked at) have a maximum sampling rate of at most, 500 samples/second -- taken from the

Hi, I am currently working on a code in Energia that will allow me to upload and send a binary file wirelessly from a client site to the CC3200. So far, the code has successfully accomplished the following: -the board establishes a Wi-Fi network -commands from a laptop can interact with the board (the Energia Simple Wi-Fi Server example (LED ON/OFF) code was tested to ensure this was working) -a 9 byte binary file is sent through Wi-Fi to the board's volatile memory, saved from volatile memory into an on-baord flash memory file, and confirmed by sending it back to the laptop through a -
My (crazy) project is getting closer to completion so time to start a project topic. I have verified my Tiva C based controller design and are now waiting for PCBs - will arrive from China in a few days. My background is from Radio/TV servicing and medical electronics, but for the last 25 years I have mainly been working on a large database application written in OpenEdge. Two years ago my preamp that I made some 30 years ago started to fail due to the rubber based switches rotting (a bit like my brain these days...). Since I did not want to buy one I decided to make a new - again with no

Hello Can someone please walk me through a suitable MCU for AIC3254/AIC3253 audio codec? From the codec's eval kit, a controller with 32kB mem with I2C/SPI is enough. Is MSP430G2744 suitable? It has 1kB RAM, 32kB flash, 16MHz and 1 I2C, SPI each. The codec would not be used for digital audio. Preferring to keep it simple. One more thing. Since there isn't much of know-how on this from my end, I would prefer outsourcing the development. Generally speaking, what should I know before committing someone to take the task? Like 1) Would I also require a separate compiler/develop

I've been looking for a while and can't find a good example showing how I can play any sort of music or speech files (mp3, au, wav, etc.). I've got a configuration setup that allows me to read files for things like LCD screens, I'm looking to read a music or speech file and play it through an amplified speaker. I'm not looking to make just tones, rather to play full music or speech files. I've found projects for Arduino such as (http://hlt.media.mit.edu/?p=1963), but nothing that works with MSP430 and Energia. Has anyone done something similar to this with Energia?

Anton Veretenenko created a simple FM Radio with a TEA5767 compatible chip. The RDA5807P is an I2C (Or spi) controlled FM Radio Tuner. He used a generic AC Powered PC Speaker, added a 3.3v regulator, a rotary encoder, and stuffed it in. The post and code don't mention it, but from the pictures, the stated 2kb limit, and the use of USI, it's using the G2231 on a v1.4 Launchpad.

VTL On the Hackaday Forums was able to use a 2kb Msp430 to trick a Audi Concert Stereo into thinking it has a CD-Changer connected, enabling Aux Inputs. The code is a Port of a Arduino Port of a AVR Port of the VWCDPIC project (PIC Based). Using a MSP430G2231, VTL was able to implement two different Uni-Direction Protocols, through Timer_A1 and the Watchdog Timer using extra software delays. The same protocol is used in B5, B6 and B7 Audi A4s i.e. Generation I, Generation II and Generation II+ Audi head units. Unfortunately, the code is no longer available, but the post is still a

Hi there. Probably some of you know already the existence of this MIDI boosterpack published on 43oh forums (check the original thread here). This board is a great tool for musicians and/or audio engineers, it features two DIN-5 MIDI connectors (MIDI IN and MIDI OUT) along with two switches and potentiometers. It allows to receive and send MIDI messages through the mcu's UART modules, and the incorporation of the potentiometers help for applications such as arpeggiators, sequencers, harmonizers and everything you can imagine. The original author provides some code examples for MSP

I am sure everybody has seen the Auduino code (Grain synth for arduino). I don't really understand the way that the PWM is setup, so I have no idea how to make this work on the MSP430 (or if it even can). Could someone explain how the timers are setup in this code? and the interrupt vector as well? I am just curious how one would setup the timer on one of the MSP430's? // Auduino, the Lo-Fi granular synthesiser // // by Peter Knight, Tinker.it http://tinker.it // // Help: http://code.google.com/p/tinkerit/wiki/Auduino // More help: http://groups.google.com/group/auduino // // Analog

This is a continuation of this project. While playing around with my WS2811 strips, I figured that it would be nice to have a board like this one. Could be used with one or two EQ chips and as a stand-alone board. The question is: with booster pack support or without?

There's a few threads on MSP430 audio playback and they've prompted me to wonder what's the best way to actually play the audio (i.e. drive a speaker, piezo) for a simple battery-powered kid's toy? A lot of stuff I can find on audio generation stops at the output to an amplifier. I've seen a few examples of directly driving a speaker (via a low pass filter) from a microcontroller pin but that doesn't seem ideal. The background to this: My 1.5 year old son likes sitting on and starting my motorbike and I've just got him his first balance bike. I'm sure he'd love a starter button and some en

Found this through hackaday. Sunrise Alarm Clock. Uses a G2553 (Programmed via Launchpad) Uses a DFC-77 Atomic Radiowave Time Receiver for, well, atomic time. Standard Character LCD (via a shift register) (and pwmed backlight) Settings through Pushbuttons Simple Alarm via PWM melody. 10mm LEDS to provide Sunlight (These could/should be replaced with high current 1a/3a type leds imho) And battery backup (with backup status recognition on p1.4 interrupt) via three diodes! A full featured project, though it could use better leds, and unless you are in Europe, a different cloc
