Hello, Datasheet recommends connecting both MUTE and STBY pins on TDA7293 using R-C for delay to avoid pop noise. I would like to know if I can connect MUTE pin using R-C, as recommended, and connect STBY pin directly to VCC. Thanks!!
Greetings. I need to use the mp3 codec library specifically developed for STM micro-controllers for my audio project (mentioned on the ST website). Nevertheless, I neither found the library to download it nor was I able to know which STM32 family members it supports. I am currently using the stm32f405 MCU. Any help will be much appreciated!
Hello Community, Does the SAI sub-block clock source matter when it is in Synchronous Slave mode with the other sub-block? In other words, should the two sub-blocks have the same clock source? Thank you.
The STA326 datasheet (DocID11531 Rev 9) is unclear on a couple of points, so: * Does the STA326 output power level depend on the output stage supply voltage (VCC[AB] on pins 4,8,11,15), or does it depend only on the digital signal chain (digital input signal and volume and effects settings) ? The output clipping level will of course…(Show moreShow less)
Hi, I'm quite new to the STM32F4 and am currently trying very simply to play audio from a binary file flashed into memory. I'm using eclipse with the ARM tool chain and the supplied drivers. I'm getting stuck on playing a binary audio file flashed into the chip at a specific address. I've very simply based my code on some of the example files,…(Show moreShow less)
On the steval-mki138 MEMS microphones dev kit, using the STAudioHub firmware and tools, I am observing a significant time drift between 2 developments kits acquiring the same audio signal at the same time. I am now looking for ways of improving this situation. Is the STAudioHub firmware source code available somewhere? Did anybody try difference…(Show moreShow less)
Hello , Could you kindly recommend me any STM kit that can be applicable for MEMS microphone ? This kit should be USB interfaced with PC, my plan is to connect it to VL812 USB 3.0 Hub Controller . Is it possible to make PDM interface with STM kit?
We are seeing some of our opamps failing, outputting the VCC rail regardless of input! The input signal is a BLDC fan current sense resistor and cell a is a non-inverting gain of 3x. Our sleep circuit was implemented incorrectly, during sleep Vcc is actually 1.5V instead of 0V, can this damage this part (note: other pins should be at 0V…(Show moreShow less)
We use osxAcousticEC library on STM32F401CBY6. For only one MCU, we can use OSX LicenseWizard to get license and this function is ok. But we are going to mass production, could you tell me how to batch obtain license? Thanks.
