I don't know if it's possible to do this for ESP 32 with internal memory. It is not known what kind of memory is installed in this ESP 32, I did not find the specification. For SPIHD, there is also a solution for ESP8266 (in DIO mode), but it already requires the intervention...
电容式触针也可以用来唤醒ESP32的深度睡眠。 GPIO4 (T0) GPIO0 (T1) GPIO2 (T2) GPIO15 (T3) GPIO13 (T4) GPIO12 (T5) GPIO14 (T6) GPIO27 (T7) GPIO33 (T8) GPIO32 (T9) 模数转换器(ADC) ESP32有18 X 12位ADC输入通道(而ESP8266只有1 X 10位ADC)。这些是可用作ADC和相应通道的GPIO G...
I read on a Russian forum that for ESP8266 (in DIO mode) there is such a solution as to tell flash memory not to use WP, but to use a software WP. I.e. the memory will ignore the input signals. This instruction is given when loading the program, via SPI into the SRP1 and SP0...

Re: ESP32-C3FN4 12,13 GPIO by AntBDokk » Mon Oct 09, 2023 5:01 pm The pins are still connected to the flash, and putting random levels on these pins may still affect what the flash does. I read on a Russian forum that for ESP8266 (in DIO mode) there is such a solution...
现在比较常见的支持Arduino的主控芯片, Mega328p / Mega2560 / Mega32u4 / stm32 / Esp8266 / esp32 等。这些芯片之间最主要的区别在于主频,支持不支持蓝牙,Flash,运存等差异。 所以与设计PC程序不同的是,在设计Arduino程序时,要尤其注意资源的消耗,因为这些芯片的可用空间真的非常小,可能有的只有2KB而已。
