Posted on April 29, 2016 at 12:19 Hello I have question about i2c. My mcu i2c pin connect to i2c pin evaluation board BU945 My i2c init like this I2C1Handle.Instance = I2C1; I2C1Handle.Init.AddressingMode = I2C_ADDRESSINGMODE_7B...
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. ...
