Hi, I am unable to communicate via i2c with the TLV320AIC3104IRHBR chip, the bus response is always busy. I'm just using the STM's internal pullup, I check it on the oscilloscope and the pins are high but no communication happens. Below is my i2c con...

Hi everyone, I hope someone can help me find or create a driver to communicate the tlv320aic3204 with the stm32f405 on my own custom board. I have been trying to replicate this tutorial (STM32 I2S ADC DMA & Double Buffering - Digital Audio Processing...

Hello guys, I hope you're doing well, I'm currently trying to replicate a video I saw on YouTube about audio processing using stm, I'm just starting to develop for stm and I'm having some doubts, mainly in terms of libs. I'm trying to convert between...

Because I'm from Brazil, and unfortunately in the national market I can only find the V2 for sale, importing the V3 is very expensive. I have a V3, or at least I did, but so far I can't find it here at my company. I'm still looking and if I don't fin...

Hi Guys, I managed to communicate with the STM via USB and record a hello word on it.I didn't have access to st link v2 and v3. However, I managed to correct the layout errors on my custom PCB. The crystal oscillator was actually on the wrong pins an...

I'm still going to install the capacitors, I'm going to a store to buy them as I don't have that value here in the laboratory. I will post the resolution of the case here as soon as the capacitors are soldered to the MCU and I use the ST LINK V2 to c...

Excellent, I haven't found the ST V3 in my laboratory, so I'm going to buy this V2.
