Re: i2c bug in 3.0, works with older idf

Current master is technically "3.2-dev". It does look like i2c_master_clear_bus code is not quite right. Previous version was slightly better, still not totally right. This may be better static esp_err_t i2c_master_clear_bus(i2c_port_t i2c_num) { I2C_CHECK(i2c_num < I2C_NUM_MAX, I2C_NUM_ER...

Re: A2DP source, connection to two bt speaker

Slightly off topic, but how does UE PartyUp mode work? They can direct multiple speakers to listen to the same single stream from the src? Essentially telling the additional speakers to passively clone (eavesdrop) the connection of the primary sink? Obviously this requires specialized software in th...

Re: ESP32 PSRAM support

They probably aren't manufacturing the 32mbit for whatever optimization reasons. But it will be a bit difficult to use all 64mbit since it would be 32mbit per CPU unshared so any task using spiram would have to be pinned to the appropriate core and not share memory with tasks on the other core.
