Re: [Answered] Calling tcpip_adapter_get_sta_list() in an event handler for SYSTEM_EVENT_AP_STACONNECTED

The post you replied to already is pretty old (that is, when keeping in mind esp-idf is pretty young), and I think the API has changed. If you look in the API docs, you'll find that esp_wifi_ap_get_sta_list probably does what you want.

How exactly are you having difficulty with this? What have you already tried?

Re: Urgent Need for Pulse Width Measurement, Register/Hardware Descriptions Would Work

I think the motor PWM unit may actually be able to do it. Not sure if that's in the TRM yet, though...

Re: Baremetal ESP32

Agreed. All the ESP32 stacks required rely an underlying OS of some kind. Why do you have the requirement to write bare-metal stuff? If any, you may able to do the radio stuff under FreeRTOS on one core, while doing whatever needs no OS on the other one.

Re: same sdkconfig but different memory layouts

ESP-IDF gives back memory used for BT Classic to the heap pool when Classic is not needed, but only does this since pretty recent ESP-IDF versions. One of the reasons for what you're seeing is that one of the examples is compiled with an old esp-idf version. Run make clean && make flash in b...

Re: Sleep timer motion sensitivity

What hardware did you use, by the way? The only things I can think of that are sensitive to motion that would be found on a normal PCB are ceramic caps; maybe they do something weird on your PCB triggering something in the ESP32.

Re: Direct IO Port Manipulation

Ah yes, using OUT0 is also an option, but it's usually not recommended because it's not atomic.

Re: Direct IO Port Manipulation

The GPIOs have a configuration register each, but the value is set using 4 32-bit registers, namely GPIO_OUT_W1TS/W1TC and GPIO_OUT1_W1TS/W1TC. You use the GPIO_OUT_* register to modify GPIO0-31, you use GPIO_OUT1_* to modify GPIO32 and higher. When you write an 1 in a bit in a W1TC register, you'll...

Re: LCD SPI & I2S - Serial & Parallel - Speed vs Ressources

FYI, if you use the esp-idf SPI driver, the transfer should be done entirely in DMA, freeing up the CPU to do other tasks. We're aware of the 4K limitation in that driver, and I expect a MR that amongst others fixes this limitation to come through within a few days. Wrt 8-bit LCD mode: there used to...

Re: when use ESP-WROVER-KIT,always getting the message"Localhost:3333:Connection timed out."

Sorry, that's not possible. The SDMMC and JTAG pins conflict, so if you use the SDMMC pins to drive a SD-card, you cannot use JTAG. On the WROVER at least, the hardware does not interfere, so if you do not use SDMMC, JTAG works fine.
