I tried to use LL library for stm32f10x without CubeMX ( * @version V1.1.1 * @date: 12-May-2017) and almost immediately found some problems:
1) You can't actually download LL library without CubeMX, even if you don't want to use Cube. That's not a but, that's just irritating.
2) It seems that you can't enable clocking of any periphery because there is no equivalent of RCC_AHBPeriphClockCmd in ll_rcc module.
3) If I enabled GPIO blocking with something like RCC->APB2ENR |= RCC_APB2ENR_IOPCEN; and then try to do:
RCC->APB2ENR |= RCC_APB2ENR_IOPCEN;
LL_GPIO_StructInit( &initStruct );
initStruct.Mode = LL_GPIO_MODE_OUTPUT_10MHz;
initStruct.OutputType = LL_GPIO_OUTPUT_PUSHPULL;
initStruct.Speed = LL_GPIO_SPEED_FREQ_HIGH;
initStruct.Pin = LL_GPIO_PIN_9; // that equals 0x04020002
LL_GPIO_Init( GPIOC, &initStruct )
This code will actually init PC.2 to output push-pull.
Why? LL_GPIO_Init does this:
pinpos = POSITION_VAL(GPIO_InitStruct->Pin);
#define POSITION_VAL(VAL) (__CLZ(__RBIT(VAL)))
obviously, pinpos will be equal to 1.
Then current pin will be calculated like this:
currentpin = (GPIO_InitStruct->Pin) & (0x00000101U << pinpos);
so currentpint will be equal to 2.
LL_GPIO_SetPinMode(GPIOx, currentpin, GPIO_InitStruct->Mode);
will be called, despite the fact that LL_GPIO_SetPinMode should accept parameters like LL_GPIO_PIN_x.
4) And here we have another 'bug' - all inline functions in header files do not check their arguments with assert_param!
I'm actually startled, how something as simple as this can be broken and not tested?! Or maybe i'm horribly wrong and just using LL library in the wrong way?
