Touch pad FSM implementation

Hi,

it is not clear to me if the FSM related to the touch pad sensor is implemented either in the ULP or it is an hardware component?
If it is implemented in ULP, where can I find the code?

Best regards,

Stefano

Touch pad FSM timer mode priority

Dear Sirs, I configured the touch pad FSM to run in timer mode (hardware timer) with touch_pad_set_fsm_mode(TOUCH_FSM_MODE_TIMER) . I experience some extra noise in the result value (count) when the system is busy. Is it possible to give higher priority to the FSM hardware timer? Which timer is used...

Asynchronous SPI slave example

Hi, I don't know how to get asynchronous communication (that is with "spi_slave_queue_trans" and "spi_slave_get_trans_result") working when in SPI slave mode. My code is the following: Init #define PIN_NUM_MOSI 23 #define PIN_NUM_MISO 19 #define PIN_NUM_CLK 18 #define PIN_NUM_CS 5 static spi_bus_con...

Re: SPI as only input pins in slave mode

Hi,
in the reference manual (chapter 5.4) it is stated that the maximum input clock frequency of the ESP32 GP-SPI slave is fapb/8.
Does it mean that in SPI slave mode the maximum communicatino frequency is 10 MHz?

Best regards.

Re: tcp socket speed 10Mbps only. How can I speed up?

Hi, interesting results. I'm facing similar problems, but worse, I can get only less than 1 Mbit/s. My configuration is: only one esp32 module connected to the AP and the computer sending the data to the module (connected to same AP via cable). Please, could you share all the example code to compare...
