Issue using PA12 #69

Closed PAk-CatchFire closed 5 years ago

PAk-CatchFire commented 5 years ago

Hi there. I am having an issue using a B-L072Z-LRWAN1 board and wanted to use PA12 as an output pin. I have checked variant cpp and added (in the digital block - position 3) the line:

{ GPIOA, STM32L0_GPIO_PIN_MASK(STM32L0_GPIO_PIN_PA12), STM32L0_GPIO_PIN_PA12, (PIN_ATTR_EXTI), PWM_INSTANCE_NONE, PWM_CHANNEL_NONE, ADC_CHANNEL_NONE },

I have alse changed:

void initVariant()
{
    //CMWX1ZZABZ_Initialize(STM32L0_GPIO_PIN_PA12, STM32L0_GPIO_PIN_PA11);
CMWX1ZZABZ_Initialize(STM32L0_GPIO_PIN_NONE, STM32L0_GPIO_PIN_PA11);

}

Then in variant.h I have added: #define PIN_D3 (03ul) but with no luck.

On the other hand, I have done the same for PA5 (as Analog1 - A1) and it worked fine for that pin.

Is there anything I am missing? Thank you

GrumpyOldPizza commented 5 years ago

I might be wrong, but there is SB15, which is not fitted per default. Without that one PA12 is not routed to the headers.

PAk-CatchFire commented 5 years ago

Thank you for your answer Thom. I have tested it with SB15 already fitted and in a custom board I have made, where I use that pin to control a switch, but with no positive results.

Is there any incompatibility as it is a USB pin? Regards

GrumpyOldPizza commented 5 years ago

I don't think there is an issue with USB vs. not. Only if you have USB enabled of course.

PAk-CatchFire commented 5 years ago

Thank you again. Would you mind to check if it is working for you?

I have used:

/*
 * Pins descriptions
 */
extern const PinDescription g_APinDescription[PINS_COUNT] =
{
    // 0..13 - Digital pins 
    { GPIOA, STM32L0_GPIO_PIN_MASK(STM32L0_GPIO_PIN_PA3),  STM32L0_GPIO_PIN_PA3,            (PIN_ATTR_EXTI),                               PWM_INSTANCE_NONE,  PWM_CHANNEL_NONE, ADC_CHANNEL_NONE },
    { GPIOA, STM32L0_GPIO_PIN_MASK(STM32L0_GPIO_PIN_PA2),  STM32L0_GPIO_PIN_PA2,            (PIN_ATTR_EXTI),                               PWM_INSTANCE_NONE,  PWM_CHANNEL_NONE, ADC_CHANNEL_NONE },
    { GPIOA, STM32L0_GPIO_PIN_MASK(STM32L0_GPIO_PIN_PA10), STM32L0_GPIO_PIN_PA10,           (PIN_ATTR_EXTI),                               PWM_INSTANCE_NONE,  PWM_CHANNEL_NONE, ADC_CHANNEL_NONE },
    { GPIOA, STM32L0_GPIO_PIN_MASK(STM32L0_GPIO_PIN_PA12), STM32L0_GPIO_PIN_PA12,           (PIN_ATTR_EXTI),                               PWM_INSTANCE_NONE,  PWM_CHANNEL_NONE, ADC_CHANNEL_NONE  },
...

Thank you

GrumpyOldPizza commented 5 years ago

I cannot check that here, because my B-L072Z-LRWAN1 is setup for SFOX, so I don't want to mess with PA11/PA12 ...

Mind asking why you want to do that in the first place ?

PAk-CatchFire commented 5 years ago

Nevermind, it was a bad soldering on that pin. The variant.cpp file is working fine.

Just one last question, is it possible to control the DBG_SX1276_DIOX pins from the code? Thank you

GrumpyOldPizza commented 5 years ago

No there is no control over the DBG_SX1276_DIOx pins. They are directly handled by the radio driver internally.
