Hi! I'm working on a project based on an esp32s2 board and I need to interface with an SD card, using the SPI peripheral. The datasheet says: ESP32-S2 family features four SPI interfaces (SPI0, SPI1, SPI2 and SPI3). SPI0 and SPI1 can only be configured to operate in SPI memory mode; SPI2 can be conf...

strange, if I run the same command in a python shell it works fine: C:\Users\kw\esp-idf>python Python 2.7.17 (v2.7.17:c2f86d86e6, Oct 19 2019, 20:49:36) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from future.utils import iteritems ...

Thanks for your reply! It sounds good... the only problem is that I can't run the mkdfu.py utility on my Windows laptop: C:\Users\kw\esp-idf>mkdfu.py Traceback (most recent call last): File "C:\Users\kw\esp-idf\tools\mkdfu.py", line 25, in <module> from future.utils import iteritems ImportError: No ...

Hi! I'd like to use DFU mechanism: https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-guides/dfu.html to upload my sketches on a devboard based on the esp32s2 chip. At the moment it seems that a specific menu choice is not available, but is it there a way to do it manually? For what I...

Hi can't compile the library (freshen.h) with the latest esp-idf... In file included from C:/msys32/home/kw/tutorial/freshen/main/main.c:11:0: C:/msys32/home/kw/tutorial/freshen/main/freshen.h:1644:15: error: field 'conn' has incomplete type struct conn conn; ^ C:/msys32/home/kw/tutorial/freshen/mai...

thanks again, it works fine!

Hi

thanks for your response.
How can I pass the two structs to the driver? I have to call the function esp_ble_gap_config_adv_data(&adv_data) twice?

Hi from what I could find, it seems that a function to set the scan response data is missing in the framework. We do have the corresponding event: ESP_GAP_BLE_SCAN_RSP_DATA_SET_COMPLETE_EVT and we also have a member (set_scan_rsp) in the esp_ble_adv_data_t struct that it seems to suggest that you ca...

Undestood, thanks!

Hi thanks for your reply... I was able indeed to use the read value in: esp_adc_cal_get_characteristics(V_REF, ADC_ATTEN_DB_11, ADC_WIDTH_BIT_12, &characteristics); but this method assumes you measure the voltage for each board you program and adapt the code accordingly... I was looking for a "softw...
