Posted on February 05, 2016 at 22:20Hello, my board designed with STM32F0 (100 pin) controller with 28 pins as input pins and 32 pins as output pins. All of the GPIO Inputs are time critical, required to sense both rising and falling edges. For this...
Posted on January 30, 2016 at 22:18I have found a problem with the latest version of STM32CubeMX 4.12.0. Each time I generate the sources with an MDK-ARM V4 project it duplicates the source files in the .uvproject file. The attached picture shows th...
Posted on February 08, 2016 at 17:03Hi,I'm having an issue setting up TIM1 for PWM on the STM32F446.In the following code, the PWM works for TIM2 but not for TIM1.Any ideas?Thank you. RCC->APB1ENR |= (1UL << 0); // TIM2 clock enable TIM2->PSC = ...
Posted on February 08, 2016 at 09:59 Hello there, I am using STM32F4. I am trying to make an application, where I could be able to modulate the frequency (not pwm) of one channel for example in range of 1k - 20k Hz. The problem i encountered...
Posted on February 04, 2016 at 13:57Hello everyone, I want to use a LCD with i80 Interface on my Eval Board MCBSTM32E. But I am failing to activate the FSMC in i80 mode. The uController stalls every time i try to Access the Memory area of the LCD. M...
Posted on February 08, 2016 at 09:02Hello. I try to use bit-banding feature in a STM32F303 uC on GPIO registers (exactly to change mode of a pin in MODER register). But as I see, all GPIO registers in that uC are on addresses which starts with 0x48....
Posted on February 07, 2016 at 09:54Hi I configured 2 EXTI (PA0 & PB1 ) and work perfectly. But when I configure Port B pins output and connect a led to them ( or even a wire!) inerrupts occure! (I pulled up intrnally and externally PA0 & PB1 and in...
Posted on February 06, 2016 at 16:12I made a custom board using stm32f105rc with external 8MHz x-tal.I think I would set the system clock with HSE,PLL,72MHz.But each stm32f105 board's SysTick_Handler timing are not same. 10,000 tick is 1 sec. In som...
Posted on February 07, 2016 at 19:55 Hello, I have an array, that should contain structures for the input and output pins as follows: typedef struct inputStruct { uint16_t pin; GPIO_TypeDef *port; }input_t; struct inputStruct inpu...
Posted on February 07, 2016 at 09:12Hi all,I have an issue with SPI on the STM32F401VC microcontroller. What seems to be the problem is that the SPI device (SPI1) doesn't seem to drive the completion flags correctly on the hardware. For example, I...
