Re: single iot-button with a range of long-hold intervals for different modes

Ended up not being able to use espressif iot-button as I'm already using esp-idf-lib and that has a 'button' component as well. Apparently there isn't a way to disambiguate two components with the same name. What I ended up doing is using esp-idf-lib's button module and wrapping it in a state machin...

single iot-button with a range of long-hold intervals for different modes

I have a use case but it isn't clear if this is something iot-button can accommodate directly. What I'd like is to use long holds to enable selecting multiple actions on a single button. For example if the user presses the button there is a beep, if they continue to hold for 5 seconds I'd like to be...

correct way to enable esp32-s3-wroom-2 psram ecc to get 85C operating temperature

Hello. Looking through menuconfig there is the ability to enable psram ecc if one enables CONFIG_SPIRAM (Support for external, SPI-connected RAM) (https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-guides/external-ram.html) It was my understanding that the esp32-s3-wroom-2 has externa...

example showing usage of blufi along side of another ble service

Hello. I'd like to provide a blufi interface to enable mobile clients to configure wifi while at the same time providing a BLE interface to enable them to control and query my device. I've reviewed the ble_multi_adv example, and tried to combine the blufi example with a peripheral example. In that c...

Re: esp-idf posix / linux support for pure software system testing?

How much support is provided via QEMU? It looked like a pretty good approach actually. For example would we get networking support? In our case we've got some hardware to mock, like we drive a motor with a pwm, so I'm guessing we'd have to make that a software virtual device. Is the QEMU approach a ...

esp-idf posix / linux support for pure software system testing?

FreeRTOS has a posix backend, letting you run freertos on linux or any other posix environment. Zephyr has support for native posix target, https://docs.zephyrproject.org/latest/hardware/emulator/index.html, which means you can build and run Zephyr and Zephyr apps on Linux. Both of these things help...

ESP32 wifi connected AC power load management system

Hello! I just launched a product using the esp32 as the controller in an AC load management system. You can take a look at it at https://op.solar I'm using it to divert solar energy to our electric hot water heater if we are net generating. It can be used to control any resistive AC load from 100-25...

Re: ADC Calibration Factory Fuses?

Following. I've switched to an i2c adc due to the issues with the esp32 adc. Would love to switch back to using the esp32 adc if the calibration brings the accuracy and error down to a reasonable level.

Re: ESP32-SOLO-1 ADC clarification

Hi @kt819gm.

Have you made any progress here? I've been looking forward to ESP32 ADC calibrations being in place for some time now, how can we tell which modules have been calibrated vs. not? It that a chip issue, are these older chips prior to the calibration being put in place?

Re: Need help to download firmware into ESP32

ESP_Angus is right. Almost all FTDI chips can only supply 50mA, so when the WiFi goes live the BROWN OUT happens. On the FTDI there is usually a voltage select jumper 3.3V/5V. I piggy backed a LM1117-3.3 and tied the center pin to the LM1117 output (no more jumper) and brownouts stop since the 1117...
