Compiling with STM32duino
PC0, PC1, PC2, PC3 defined in Renderer3D.inl conflict with #define pinout definitions of the STM32.
Suggest to change to _PC0, _PC1, _PC2, _PC3. That seems to resolve the compile issue
i also added this to misc.h. i haven't checked yet if stm32 has a native sqrt implementation.
#if defined(ARDUINO_ARCH_STM32)
#include "Arduino.h"
#define TGX_ON_ARDUINO
#define TGX_USE_FAST_INV_SQRT_TRICK
#define TGX_USE_FAST_SQRT_TRICK
#define TGX_USE_FAST_INV_TRICK
#endif
and defined(ARDUINO_ARCH_STM32) to the following.
#if defined(TEENSYDUINO) || defined(ESP32) || defined(ARDUINO_ARCH_STM32) // On teensy, 8K give good results... #define TGX_PROGMEM_DEFAULT_CACHE_SIZE 8192 #else // make it bigger on CPU... #define TGX_PROGMEM_DEFAULT_CACHE_SIZE 262144 #endif
STM32 could use a bigger cache than 8192 as it has more memory, but in most applications 262144 will be too big. so for now I'm sticking to 8192.
Hi,
Thanks for the suggestion !
I implemented the changes so hopefully it helps with STM32Duino compatibility. Beware that the changes have been made on the improved_drawing_primitives branch which has many bug fixes, some speed improvement and a much better 2D drawing API and which will become the master branch 'soon'.
As for the existence of a fast sqrt on STM32, I do not know but I suppose it is very similar to Teensy since it also use ARM Cortex-M cores so I am using the same presets for both.
Best,
