Re: ESP32 with ACS712
You read 2900 which is near 2.5v. You should use voltage divider to halve output of acs712, keep in linear region of ADC, then calibrate and convert.

Re: App. upload UART2 how to: for ESP32 Adafruit demo board
You may have to do the opposite. This happens in ROM code. But you could potentially add your own uart2 OTA loader in a custom 2nd stage bootloader or in firmware code.

Technical Reference I2S Clock config section is confusing
For the configuration of I2S0 peripheral clock output: When PIN_CTRL[3:0] = 0x0, select and output module clock on the CLK_OUT1 in the IO_MUX Pad Summary; When PIN_CTRL[3:0] = 0x0 and PIN_CTRL[7:4] = 0x0, select and output module clock on the CLK_OUT2 in the IO_MUX Pad Summary; When PIN_CTRL[3:0] =...

Re: spi and rtos panics
Does msdelay use vtaskdelay? Probably want bigger stack size.

Re: RTC battery supply
Depending on what is the goal... If the goal is to keep just the RTC working in the event of loss of power, then powering VDD3P3_RTC with a battery-backed supply is enough. If the goal is to also save main memory contents, then VDD3P3_CPU should be battery-backed as well (although this will likely ...

Re: ESP32 Pin Layout (for QFN 5*5), Pin25, Pin26
So either pin 1 is on the 10-pin side and numbering is clockwise or pin 1 is on the 14-pin side and numbering is anticlockwise? Numbering shown from (rotated) bottom view by mistake?

Re: Interact with a bluetooth 3.0 game controller
Probably none because Bluetooth classic is not implemented yet.

Re: RTC battery supply
Does battery have to also connect to VDD3P3_CPU sinceESP_igrr wrote:You can connect both battery and main supply to the RTC via a couple of diodes (or a more complex switching circuit).
or is it OK to cut power to VDD3P3_CPU but not VDD3P3_RTC?VDD3P3_CPU is also the input power supply for CPU
