Hi, yes that makes sense. I was using uint8_t for addr because I wanted to access the memory as a byte, but yes, it makes sense that the compiler would question it. I'll change it and see. I was going to use a Union instead, which seems neater but maybe not as efficient. Thanks for the support. Pete

I'm getting a 'suspicious pointer conversion warning' for the following code; it works OK and does what I want, but why the warning? /* Convert int16 to bytes ---------------------- */ void int2Bytes(int16_t parameter, uint8_t *pMSB, uint8_t *pLSB) { uint8_t * addr; addr = ¶meter; *pLSB = * addr...

That works, fantastic. Basically I had the interrupt vector wrong.

Thanks again for the great support

Pete

I tried slowing down the clock to the IO pins (APB2), but this didn't help.

Thanks
Pete N.

Hi Jovana, thanks for replying to my post. Please find attached the project zipped up. I am doing the development on my own hardware, but this bit is a LIS3DSH accelerometer connected to PB5, with a 82K pull up. I can see the INT pin activity on a scope. Also, if I put some code into the micro to de...

Hi, I'm trying to get an external interrupt to work on port PB5. Interrupt on the rising edge. I can see the IO pin going high on a scope, and if I put some code in to detect PB5 going high it works. I just can't get the interrupt routine to work. Here's the code: I can see the EXTI_PR bit go high i...

I sorted it, being daft!

GPIO_Config(&GPIOA_BASE,_GPIO_PINMASK_8,
_GPIO_CFG_MODE_ALT_FUNCTION | _GPIO_CFG_SPEED_50MHZ | _GPIO_CFG_OTYPE_PP);

GPIO_Clk_Enable(&GPIOA_BASE);

Cheers

Hi, How do I configure pin PA8 on an STM32F105 to output the system clock? On another project that used a STM32L053C8 i used: GPIO_Alternate_Function_Enable(&_GPIO_MODULE_MCO_PA8); GPIO_Clk_Enable(&GPIOA_BASE); and set the MCO to output the system clock in the project and it worked no worries. Howev...

Hi, I'm trying to get the PWM working on a STM32L053C8 and have the following code: uint16_t ratio = PWM_TIM2_Init(10000); GPIO_Alternate_Function_Enable(&_GPIO_MODULE_TIM2_CH1_PA0); PWM_TIM2_Set_Duty(2500, _PWM_NON_INVERTED, _PWM_CHANNEL1); PWM_TIM2_Start(_PWM_CHANNEL1, _GPIO_MODULE_TIM2_CH1_PA0); ...

I have this bit of code on a STM32L053C8: uint16_t ratio = PWM_TIM2_Init(10000); // Set the output frequency GPIO_Alternate_Function_Enable(&_GPIO_MODULE_TIM2_CH1_PA0); PWM_TIM2_Set_Duty(2500, _PWM_NON_INVERTED, _PWM_CHANNEL1); PWM_TIM2_Start(_PWM_CHANNEL1, _GPIO_MODULE_TIM2_CH1_PA0); It's to try ou...
