I got an error in functions max() and min() parameters, I "fixed it" casting max_buffer_size as int, but when I executed and wrote some data in serial monitor I got another an error, I think it is something about invalid memory...
I am new using arduino ide and esp32 and need to write a code to read from a SPI master some temperature data (16 bits), nothing more than that, I don't need to write to master neither gpios. How could I change this example to do that?

Hey there,
I could fix the compile errors and warnings, which turned out to be just 2 tiny problems.
At the moment I do not know if it makes the program work.
Fix #1
The same name is used for a static member and an instance member.
In SlaveSPIClass.h @ line 2
static int size;becomes
static int size_;In SlaveSPIClass.cpp @ lines 2, 6, 14: replace occurrences of SlaveSPI::size with SlaveSPI::size_.
Fix #2
The compiler messes up the implicit conversion from integer literal to t_size.
SlaveSPIClass.cpp @ line 41
driver = new spi_slave_transaction_t{t_size * 8 , 0 , heap_caps_malloc(max(t_size,32), MALLOC_CAP_DMA), heap_caps_malloc(max(t_size,32), MALLOC_CAP_DMA),NULL};becomes
driver = new spi_slave_transaction_t{(size_t)(t_size * 8) , 0 , heap_caps_malloc(max(t_size,(size_t)32), MALLOC_CAP_DMA), heap_caps_malloc(max(t_size,(size_t)32), MALLOC_CAP_DMA),NULL};
I feel like something else is wrong with size and size_.
Fix #3
It does not make sense that an instance value is used in the constructor SlaveSPI::SlaveSPI() because size is only used to affect the static member SlaveSPIVector.
SlaveSPIClass.cpp @ lines 20 to 33: replace every size with SlaveSPI::size_.
Possible fix
The instance's size is not explicitly initialized. It looks like a buffer count. It should probably be initialized to 0 in the member initialization part of the constructor. The default value is to be checked.
EDIT #1
Yes! My fixes #1 to #3 made it work somehow! I was receiving nothing at all without the fix #3. Now I'm receiving a corrupted message but at least I have a correct piece of it.
I am using platform IO, and after implementing all the fixes above, I cannot compile:
My error is inline 29 of .cpp file: tx_buffer = (uint8_t *)heap_caps_malloc(max(max_buffer_size, 32), SPI_MALLOC_CAP);
the error is: no instance of max(size_t,int)
any help or suggestions?

cannot compile (with ESP32 Arduino core v1.0.1) , get the following error:
