Re: New $23 ESP32 audio board on Kickstarter

How do you get the mentioned 16 MB Ram / how you declared 4x4 via MMU? 16 MB RAM (available as 4 x 4 MB banks via MMU) Do you pick something off the eMMC? That would be very interesting in a possible direction. Not that it isn't possible - it's just FLASH, but I'm already curious. Thank's so much f...

New $23 ESP32 audio board on Kickstarter

I'm happy to announce my new ESP32 audio board called "WVR" is up on Kickstarter today. It pairs an EPS32 WROVER-B with 8GB of eMMC memory, a hifi DAC, and an opto-isolator for MIDI, and its only $23 USD. There are also 2 different dev boards, a USB MIDI HOST add-on, and a stomp box version availabl...

Re: port IDF project to arduino

I have had SOME success with using absolute #include paths to my installation of esp-idf, but this approach is not portable, I imagine, so the end user of this board will not be able to compile their code from Arduino.

Do I just need to write everything within the esp_arduino framework?

port IDF project to arduino

I am designing a new dev board based around esp32 wroverB, and I have a large code base that I wrote in esp-idf (v3.3) which does all the setup for this board. Now I want the end users to be able to work in the Arduino IDE, to write their code for the board. What is the best approach here? When I si...

Re: eMMC module

my understanding is that there is a latency overhead with both read and write operations associated with the 'S' for secure in SD ... My speed tests support this.

getting starting with wroverB bare module

I am trying to migrate from using the wroom devkitC, to a wroverB bare module. I have searched the internet and not found a good tutorial on this process, can anyone point me to one? I have a ftdi connection established, and received "flash read err, 1000" Do the WroverB modules ship with a 2nd stag...

IO MUX or GPIO matrix with TOUCH pins and ADC pins.

I'd like to be able to assign different pins for both the TOUCH sensor, and ADC peripherals. How can I use the IO MUX and/or the GPIO MATRIX to achieve this? I havn't been able to find any mention of it in docs, datasheets, or online, so maybe it is not possible at all? I have a WROVER Dev board, an...

Re: example of HTTP server in AP mode?

unfortunately the suggestions above do not work for esp-idf version 4.
Is anyone able to suggest code to run a softAP http server in v4.1?
or perhaps able to port the code?
