Re: Some invalid I2C register reads
May want to play with those; enable internal pullups or change to e.g. 5k. I did try 1k and 4k7, but that did not make any difference. The error persisted. But I'll use 4k7 from now on, thank you for the info! 0xA3 happens to be (0x51<<1)+1, which may be a hint that the first bit (MSB) gets missed....

Some invalid I2C register reads
ESP32 Wrover-E IDF 4.4 ADF 2.4 Hi, I'm currently facing some problems when reading registers from an IC via I2C. I'm getting like hundres of correct reads, but at some point I get an incorrect one. I've watched the I2C lines with an oscilloscope and the data looks fine, so the problem happens intern...

Re: How much SRAM is actually usable?
That's sad news unfortunately.
But thank you for your answer!

How much SRAM is actually usable?
I'm developing a relatively large application on an ESP32-WROVER-E. Currently I'm running into an issue, where i need more RAM. My goal is to store a JPEG (640x480), but i have only 35kB left, which isn't enough in some cases. I don't wanna go into discussions about using dynamically allocated mem...

Re: A2DP sink volume cap
I've looked into that problem again and still didn't find an answer. In `btc_a2dp_sink_handle_inc_media` in the file `btc_a2dp_sink.c` the incoming data gets converted via `OI_CODEC_SBC_DecodeFrame`. If i check the data directly after the conversation i can see the same problem as in the output. A v...

A2DP sink volume cap
ESP32 Wrover-E IDF 4.4 ADF 2.4 Hi, i've set up an A2DP sink ( https://github.com/espressif/esp-adf/blob/master/examples/player/pipeline_a2dp_sink_stream/main/play_bt_music_example.c ) and modified it. I can play music via bluetooth and the remote control also works well. However i have difficulties ...

Re: Flash Encryption and non-OTA updates
I want to achieve a goal similar to what @M-Schiller wants.
Does someone have answers to his questions?

A2DP sink controls stop working
Hi, I'm currently trying to get this example to work on my custom-board: https://github.com/espressif/esp-adf/blob/master/examples/player/pipeline_a2dp_sink_stream/main/play_bt_music_example.c I changed it up a litte. The code is below. My problem is, that the controls (prev, play, pause, next) stop...

Re: ESP32 IDF SPI slave not receiving any data
Let me share my results with you: At first the most important info: You need a CS for an ESP32 as a SPI slave, if you don't want to overcomplicate your software. 1st issue I had: What the ESP32 IDF really needs is the end of the transaction as a rising edge on CS. Else it doesn't know when the trans...

Re: ESP32 IDF SPI slave not receiving any data
I tried pulling a GPIO to low (CS is active low) and selected it as CS, but it isn't working. I'll try using a CS line from the master to the slave, but it will take a while since we have to modify our custom board. => Sharing my results later! But I think in general this implementation is just inco...
