Posted on April 19, 2016 at 15:18Hi, I´m using TIM3(output compare mode) in stm32f072 to generate waveform via GPIO. My function principle is: - timer initializing - timer is still running, only is enabled TIM_IT_CC3 a output TIM_CCER_CC3E (BUS_Set_...
Posted on April 28, 2016 at 07:11Hi, I have made a custom bootloader, but it sometimes freeze when going from bootloader to the actual firmware. Usually the bootloader should just go to the firmware by doing the following:uint32_t startAddress = *(...

Posted on April 29, 2016 at 07:22Hello, I have discovery board , which runs with stm32f407vg MCU. i want to measure the system core clock by bringing it on the gpio or any other means ??Is it doable ? please help me how to do it #clock #stm32
Posted on April 24, 2016 at 06:25Simple question If I set some interrupts priorities to 0, should I expect time measurements (down to the microsecond) to be inaccurate? ( using SystemCoreClock and SysTick->VAL )
Posted on March 28, 2016 at 18:59Hi,I would like to share an idea here about a way to auto-test our boards (based on STM32F215 LQFP64) to prevents shorts in both contexts:1. after reflow process as partial QC,2. during the product life: after each s...
Posted on April 28, 2016 at 07:44I'm using the STM32F105R8 on a custom 4 layer board. Boot0 is pulled to ground via a 10k resistor. Boot1 is floating. The board is based on some open hardware with associated open source software. I'm using the sa...
Posted on April 26, 2016 at 08:28hello I get overflow on DCMI .please see my code.DCMI config : hdcmi.Instance = DCMI; hdcmi.Init.SynchroMode = DCMI_SYNCHRO_HARDWARE; hdcmi.Init.PCKPolarity = DCMI_PCKPOLARITY_RISING; hdcmi.Init.VSPolarity = DCMI...
Posted on April 28, 2016 at 15:20Dear all, I have problem transferring relatively large block data (>= 600 bytes) over USART. All blocks smaller than 600 bytes can be sent successfully from MCU and the host at the other end receives that correctly. ...
Posted on April 28, 2016 at 08:31Hi, i want to design the mapping of my board. I need CAN3. In the STM32F767 Datasheet an unconsistency. In chapter 3 Table 10 (pin and ball definitions) is descriped that at pin PA8 the CAN3 is possible as alternate ...
