I haven't and it looks like that's exactly what I need. Thanks!

Hi

I'm trying to run the CDC-ACM Usb Host example with an FTDI RS485 adapter but my ESP32S2 fails to identify it as a serial device. The bDeviceClass, bDeviceSubClass and bDeviceProtocol fields of the device descriptor are all zero.

Code to list some of the fields:

usb_device_handle_t current ...

I get linker errors when I try to use regexes with rtti enabled (by adding "build_unflags = -fno-rtti" to platformio.ini). It does link without rtti.

Here's the sketch:

#include <Arduino.h>
#include <regex>

void setup() {
Serial.begin(115200, SERIAL_8N1);
}

void loop() {
std::regex reg("man ...

No, sizeof(size_t) equals sizeof(size_t*), 4 on the ESP32. I was thinking what if there's a 'new' running before my sketch and the memory is released with my custom delete, that would cause a corrupted heap. So I used the extra memory as a tag, turns out there are 5 objects getting deleted that ...

Hi,

I' trying to override the new/delete operators to add some data to any dynamically allocated memory, like this:

void * operator new(size_t size)
{
size_t* ret = (size_t*)malloc(size + sizeof(size_t*));
*ret = 0;
ret++;

return (void*)ret;
}

void operator delete(void * ptr)
{
size_t ...
