Support for STM32 #87

Open dasaki opened 6 years ago

dasaki commented 6 years ago

In order to add support for stm32duino platforms the following definition is needed:

#if defined(__arm__)
#ifndef __NOP
#define __NOP __asm volatile ("nop")
#endif
#endif

Adding the definition to the file Ucglib.c worked with a maple mini clone and a ST7735 TFT: Ucglib_ST7735_18x128x160_HWSPI ucg(/cd=/ PA2 , /cs=/ PA4, /reset=/ PA3);

Confirming that the definition works with Ucglib_ILI9341_18x240x320_HWSPI() on a Blue Pill as well.

NOT WORK FOR with Ucglib_ST7735_18x128x160_HWSPI ucg(/*cd=*/ PA1, /*cs=*/ PA0, /*reset=*/ PA2); on a Blue Pill. BUT WORKS just with #define __NOP __ASM volatile ("nop"); added to Ucglib.cpp : line 43

Works on China board with stm32f103 rc (diymore)

Hi, for me WORKS just with #define __NOP __asm volatile ("nop"); added to Ucglib.cpp : line 43 and in IDE I use: Ucglib_ST7735_18x128x160_HWSPI ucg(/*cd=*/PB1, /*cs=*/ PB12, /*reset=*/ PA4); (STM32103FC with STM32duino core 2021.2.19)
