Reliable Second Source for ESP32 PSRAM

Hello all, one of the industrialization issues of the ESP32 WROVER moduls is the availability of ESP32 PS RAM, coming from a more or less single source. Manufactured by Espressif as well on the module itself it should usually not be so much of an issue, as Espressif has the control. But pretty surel...

Re: ESP32 Webradio

Hello Guys, I am still pretty new to the ESP32 and I think it has a very capable set of features. Impressive part really. In a project I am working on a webbased radio. I know there are implementations with the ESP32. The two main approaches I found are: - ESP32 with ext. VS1053 audio Decoder and Di...

Re: ESP32 WROVER MP3/AAC/(IP Audio Stream) Decoding, digital Audio Filtering and SPI Colour Display control

Hello ESP Sprite and Psycoacoustic, sounds like good news. The questions was of that nature to sort out wether or not we have a chance to do so in ESP32. We will likely contract a 3rd party copayn to evaluate the capabilities as ESP Sprite said in more detail. Currently there is not enought resource...

Re: ESP32 GPIO Muxing Function posssibilities: I2S, I2C, SPI, UART, int RAM/ROM, touch and some GPIOs

Hi ESP Sprite. Thanks. I know about the limitiations of the SDIO/QSPI interface for external use when internal PSRAM/FLASH is used. We intend to use RAM/ROM so we preserve for that by not using those pins. If all others can be used more or less freely than this is good info. I was concerned if there...

Re: ESP32 GPIO Muxing Function posssibilities: I2S, I2C, SPI, UART, int RAM/ROM, touch and some GPIOs

Hello guys, I guess I overdid a bit with the first request, so I try to simplify. do you think it is possible from the I/O pinmux point of view to run both I2S AND a VSPI Interface (or other faster SPI IF) for the display in parallel, maybe considering the other interfaces above? Is there any guide ...

Re: ESP32 WROVER MP3/AAC/(IP Audio Stream) Decoding, digital Audio Filtering and SPI Colour Display control

Thanks ESP_Sprite. These indications are a good hint. Could you let me know what HW (ESP32 EValsystems or Modules) you use for it? In the meantime I have found the audio development framework section, which seems to answer a lot of questions. But usually these are single functions (like MP3 etc deco...

ESP32 WROVER MP3/AAC/(IP Audio Stream) Decoding, digital Audio Filtering and SPI Colour Display control

Hello guys, I am aware the ESP32 (Dual Core) can decode mp3 and other streaming audio formats (basically in SW). Too, I am aware the ESP32 can drive a Colour TFT via SPI (standard 4 lane). Basically I would like to get your feelings for possibility of parallel operation (MP3 decoding AND display con...

ESP32 GPIO Muxing Function posssibilities: I2S, I2C, SPI, UART, int RAM/ROM, touch and some GPIOs

Hello ESP developers, My company and I are defining a System with the following interface needs: - WiFI/BT (as wireless frontends), both 2.4GHz CoEx - I2C (System config) - I2S (or PDM) (ESP32 Audio output to Amplifier/DAC) - touch button Matrix 2x3 (user input) - SPI (to config and feed a small LCD...
