I am having an STM32F411E board and I am trying to read values of MAX4466 analog mic using the onboard ADC interface(12 bit resolution). I get values starting from around 1000(0.8 V) and whenever I make sounds it slightly increases and that's it. I'v...
Hello everyone,I am currently using the WM8904 audio codec in my project. The audio is stored in external flash memory, and I am reading it in chunks of 1024 bytes at a time. The audio format is 16-bit WAV with an 8000 Hz sample rate.For playback, we...
We are implementing two TDA 7293 amplifiers in a Master / slave configuration, for a 35 watt, 30 kHz drive of a high frequency device that operates between 2.8 ohms and 7.1 ohms on the output pins (5.6 ohms to 14.2 ohms per amplifier). We have a coup...
Hi, I am trying to interface a graphical LCD (ST7567) with the STM32G0B1RCT6 using the U8g2 library and a software SPI interface. I have the U8g2 driver, but I don't know how to configure the ST7567 driver with the STM32G0B1RCT6. I will attach the...
Hello,Please find the below image we design schematic and doing testing of this circuit. This design functionality is working but during capturing the waveform of current waveform and Xfmer input voltage waveform we observed high spike as highlighted...
Hi ST TeamI have a question about the TDA7266D13TR product.Checking the TDA7266D13TR datasheet gives the specifications for the TDA7266D and lists the operating temperature as 0°C to 70°C.The temperature specification I need is -20~85°C or higher.Ple...
Hello,I have a couple of diodes that needs replacing, but I can't decode the markings. Is there a reference manual or an easy way to find the right diode?The markings are:ST-logoT01C029Can anyone help?Thanks! Elco
Hi, I'm trying to read an LCD 8 bits information, so I need to quickly change PA0 ~ PA7 to input, then read the IDR register, and return them to output after reading the 8 bit bus, but I need help. Thank you all.
Hi,I am posting this question, same as I have posted on the stackoverflow to find some clues into my problem.I had been programming my STM32F407 MCU for almost 6 years using OpenOCD's GPIO Bit bang driver over Raspberry-pi for Serial Wire Debug for a...
I am trying to implement a gesture recognition system using tensorflow lite and mpu6050 but for that I have to use tensorflow lite micro in my STM32F446re but after downloading it from github repository I saw it is being build by Bazel but I usually ...
