Posted on August 16, 2017 at 17:33In TIMERS/03_InputCapureOnTI1/main.c and TIMERS/04_PWM_Input/main.c the flags after an interrupt are being cleared this way:TIMx->SR = ~(TIM_SR_CC1OF | TIM_SR_CC1IF); /* Clear the flags */Shouldn't it be like below?...
Posted on August 16, 2017 at 04:00There is much information for the hard fault:SCB->HFSR: 40000000SCB->CFSR: 400MSP: 2000fb58 PSP: 200193b8 LR: fffffff1 r0: 0 r1: 2000dcd0 r2: 8000529 r3: 1 r12: 0 LR: 0 PC: 8030ba0 PSR: 2100000fwhat method c...
Posted on August 09, 2017 at 13:57Hi,I'm using STM32F030F4 MCU for LED blinking function. I used below code with Keil IDE. But I'm not able to get the output. Boot0 pin pulled low for internal flash boot loader.Added Corresponding ST pheripheral lib...
Posted on August 16, 2017 at 16:46Hi, I am having trouble getting an interrupt working with the TIM3, roughly following this guide: http://www.micromouseonline.com/2016/02/03/tim3-arr-regular-interrupts-stm32f4/ but adapting for the STM32F0308. TIM3...
Posted on July 26, 2017 at 14:19Hi All,A brief background:I'm a hardware guy and new to all things ARM and STM32 MCUs. I've now jumped on board because ST has an agreement with Keil for STs Cortex M0/M0+ MCUs. I've programmed before but only 8-bit M...
Posted on July 27, 2017 at 12:47Hallo,I am trying to Read GPS data from a uBlox LEA via I2C with a STM32L073RZ (Nucleo Board). I am able to read EEPROMs with the HAL Libraries in Blocking and Interrupt Mode. The EEPROM i am using is a 24LC64 and it...
Posted on August 16, 2017 at 18:56How can I trigger ADCs for injected conversion at CTR=PRD when my TIM8 is configured for up-down counting? I don't see any mechanism that can do this.
Posted on August 14, 2017 at 23:13I need help setting up and enabling (and disabling) the Spread Spectrum Clock on STM32F405.AN4850 is not enough, as it has no code example; says nothing about what to do with MODPER and INCSTEP once calculated.I se...
