Re: How to flash a WROOM module using an FTDI programmer?

Same thing here is the screen shot. You can just drag your .jpg file into the post, then click place inline. That works for me.

Re: FreeRTOS Task notification crashing esp32.

The first thing that jumps out at me is that your stack allotment is to low for using a printf.
Kick them up to at least 2048 and try it.

xTaskCreatePinnedToCore(task1, "Task1", 2048, NULL, 1, &task1_handle, 1);
xTaskCreatePinnedToCore(task2, "Task2", 2048, NULL, 1, &task2_handle, 1);

Re: Proper way to power ESP32 from the main supply

Would a 0-2.4A self-regulating unit work well? Any regulated 5v splly will work, assuming it can provide enough current for your board. I.E. its not a 5v 100ma supply. There are many quality supplies. https://www.digikey.com/products/en/power-supplies-external-internal-off-board/ac-dc-desktop-wall-...

Re: Proper way to power ESP32 from the main supply

Any reputable 5v-5.1v 1A wall wart will be fine.

Re: FreeRTOS Task notification crashing esp32.

Probably be better to answer the question if you posted your code.

Re: Trouble powering ESP32 using Raspberry Pi

Do you have a volt meter that you can measure the 5v on the HUZZAH32 regulator

Re: Trouble powering ESP32 using Raspberry Pi

What are you powering the RPI with? You should have one of these in your arsenal. https://www.amazon.com/Eversame-Multimeter-Voltmeter-Indicator-DC3-6-30V/dp/B07JYVPLLJ/ref=pd_bxgy_3/143-1917623-3400526?_encoding=UTF8&pd_rd_i=B07JYVPLLJ&pd_rd_r=ca332788-e36a-4aed-9f28-e59d9f67b3db&pd_rd_w=6m6tg&pd_r...
