Re: How to display image on webserver
However, the issue is when I try to display the image together with other html elements on my index page. I would like to display the logo, some text, some tables and other things: The html and the image should be separate HTTP requests*. Headers are sent first, including the Content-Type which spe...

Re: esp_partition_write for OTA
if ((received = httpd_req_recv(req, buf, MIN(remaining, 512))) <= 0) ... ESP_ERROR_CHECK(esp_partition_write(partition, 0 + (iterator * 512), buf, MIN(remaining, 512))); You're unconditionally writing 512 bytes of the buffer, despite perhaps having less available. Everything after the actual number...

Re: How can I place a variable at an absolute address? Pass value between bootloader hook and application.
I don't think it's possible to specify an address. You would need to maintain a custom esp_system component with your new section specified in the relevant linker script. I had a need for the same thing this week - reserved RTC slow memory without having to have an entire esp_system hanging about to...

ESP32 datasheet, section 2.3: • In scenarios where ESP32 is powered on and off repeatedly by switching the power rails, while there is a large capacitor on the VDD33 rail and CHIP_PU and VDD33 are connected, simply switching off the CHIP_PU power rail and immediately switching it back on may cause a...

Re: WiFi switch without disconnect.
Yes you can change modes without needing to stop and restart the driver.

Re: GPIO Interrupt from a class file
ANSI_Encoder.h: uint32_t C_cnt; rotary_encoder_example_main.c: #include "ANSI_ENCODER.h" printf("CNT C: %d\n", C_cnt); ANSI_Encoder.c: uint32_t C_cnt; C_cnt++; By including ANSI_ENCODER.h in your main.c, you declare a C_cnt in that translation unit. This is not the same memory as the C_cnt in the A...
