Re: Any information for SYSTEM_EVENT_AP_STAIPASSIGNED callback?

You can use wifi_sta_list_t station_list; esp_wifi_ap_get_sta_list(&station_list) wifi_sta_info_t *stations = (wifi_sta_info_t*)station_list.sta; to get the stations list. Than you can iteraatee trough stations list to get the stations IPs: for (int i = 0; i < station_list.num; ++i) { ip4_addr_t...

Re: ESP-WROOM-32 and extending the flash

AnalogLamb has ESP32-WROVER Breakout Board for 1.99 US$, but without USB2UART chip, and ESP32 Fixer Board for ESP32-WROVER, but it is not cheap (18.88 US$).

Re: ESP-WROOM-32 and extending the flash

I have replaced the original Flash chip with W25Q128FV on several ESP-WROM-32 modules and it works without any issue (QIO mode/80 MHz). I don't see any reason why it shouldn't work as external Flash also. By the way, it is easy to add the SPI-RAM to. http://loboris.eu/ESP32/ESP32_Feather_psRAM.jpg E...

Re: ESP32 TFT display library

@rolobr Thank you. Any help on making SD Card using SPI and this library work together ? I am stuck now since this an important requirement for me :( I have SDCard in SPI mode and display working together in my MicroPython project. It requires some changes to esp-idf sources ( sdmmc_cmd.c , spi_mas...

But $2/mbit vs $0.10/mbit

And max size 128 KB + max clock 20 MHz, quite unusable as ESP32 external RAM.

Re: Reading values of Onboard Temperature sensor

The exaple code in test_tsens.c can also used for reading the internal temperature sensor.
It looks like temprature_sens_read() function from librtc.a always returns 128 with the latest master esp-idf.

Re: SPI RAM - Support for other chips

Hi all, I love the fact that the ESP32 supports SPI RAM. I understand that there are limitations to putting a lot of RAM on-die, so I appreciate the option of being able to implement external RAM. However, I was surprised to see that the only chip that's supported is the PSRAM chip manufactured by ...
