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...

Re: ESP32 goes into unknown state
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...

Re: ESP32S2 custom dev board design, schematic check please
Could use some more capacitance, especially either side of the LDO and ESP32 VCC Need a ~1uF capacitor on ESP32 EN Suggest grounding the pad of TP4056 Suggest a reasonably high resistor (eg. 10-100k) on VBUS to GND, in order to tie TPS2113 VSNS low when VBUS is disconnected There's no protection on...
