Thats more or less the following spaces: SPI 0x3FF42014 - 0x3FF420BC GPIO/MUX 0x3FF44004 - 0x3FF484C4 ULP RTC 0x3FF48818 - 0x3F...

Hello Jacques,

A pointer to memory is stored in PCNT_U0_CONF0, so far so good. Why the index [0] is used to get access to the memory ? Background for the problem: I tried to meas...

Hello together, I use a ESP32 WROOM module and tried to program the internal PCNT module via register access with the machine function mem32. Unfortunately, it doesn't work as expected. I tried to manipulate the PCNT_U0_CONF0 register >>> bin(mem32[0x3FF57000]) '0b11110000010000' >>> mem32[0x3FF5700...
