Re: ESP32 PullUp- PullDown

When calling the pinMode function specify mode INPUT_PULLUP to enable the internal pullup resistor or specify mode INPUT_PULLDOWN to enable the internal pulldown resistor. For example, to enable the pullup resistor for GPIO17 do this: pinMode(17, INPUT_PULLUP); To enable the pulldown resistor for GP...

Re: tick example code

And there's also the esp_timer API described at https://docs.espressif.com/projects/esp ... timer.html with an example of it's usage at https://github.com/espressif/esp-idf/tr ... /esp_timer

Re: tick example code

Hi, is there any example code related to os_tick_start and os_tick_handler. thanks, Madhu I'm not aware of functions called os_tick_start and os_tick_handler in an esp-idf context. If the goal is to use timers then esp-idf does offer timer support. See https://docs.espressif.com/projects/esp-idf/en...

Re: Wifi won't connect on certain boards

The DFRobot log shows the following:

Code: Select all

I (756) wifi station: connect to ap SSID:1 password:123456
Are the SSID and password for the access point really 1 and 123456? Or did you forget to modify the code and set the SSID and password to the correct values?

Re: ESP32 Azure IoT Kit

I'm not sure if it's exactly the same but the esp32_azure_iot_kit example in the esp-iot-solution project look like the demo that runs on a stock ESP32-Azure IoT Kit.

See https://github.com/espressif/esp-iot-so ... adme_en.md

Re: vTaskDelete sometimes hangs current task

If the following line is added directly before the call to vTaskDelete, does it print the name of the task that should be removed?

Code: Select all

ESP_LOGI(TAG, "deleteting task with name %s", pcTaskGetTaskName(todel->task));
If the correct name is not printed, todel->task doesn't contain the correct handle.

Re: Is it safe to read and write UART from different tasks?

There's an esp-idf example called "UART Asynchronous Example with Separate Receive and Transfer Tasks" at https://github.com/espressif/esp-idf/tr ... _rxtxtasks so it looks like it can be done.

Re: Which version of the 3.3 branch is most recent

Which version of these two 3.3 branches of the IDF is the most recent and up to date? v3.3-dev-278, or v3.3-beta1-223? I'm not sure where the numbers 278 and 223 are from but the esp-idf git repository has two tags called v3.3-dev and v3.3-beta1. v3.3-beta1 is newer than v3.3-dev. All the tags for ...

Re: ESP-WROVER version for new design

For a new design shall we choose ESP32-WROVER-I or ESP32-WROVER-IB? The Espressif Product Ordering Information lists the ESP32-WROVER-IB as "*Recommend" but it doesn't list the ESP32-WROVER (IPEX) as "*Recommended". My personal interpretation of this is that the ESP32-WROVER-IB should be used for n...

Re: IOT-Solution examples on ESP-wrover-kit V3

@Alen59 To the best of my knowledge no additional resistors are needed. Is the latest version of esp-iot-solution being used and was the menuconfig option "Select Backlight Active Level" set to "Backlight Level Low"?
