Posted on June 26, 2014 at 11:40 I would like to optimize next snippet: void write16Data(u16 data) { GPIOA->BSRR = 0x00ff0000 | (u8)(data & 0xff); GPIOB->BSRR = 0x00ff0000 | (u8)(data >> 8); } Any ideas?
Posted on June 05, 2014 at 14:30Hi, I am using TIM3(PC6 to PC9) for PWM output in STM32F215. In this I want three 50Hz PWM signals and one 8KHz signal. So I have configured PC7,PC8,PC9 as 50Hz PWM signals. For this i have assigned PrescalerValue_50...
Posted on June 26, 2014 at 12:24Hi, I am using stm32l152r8 in my custom board.In this while I running the code I am getting error which is can not access the memory. After some time i found the error which is if ((RCC->CR & RCC_CR_HSERDY) != RESET)...
Posted on June 26, 2014 at 12:50Hi, I am using STM32F215(master) in my custom board. In this controller is connected to the MPU9150 sensor(slave) via I2C interface.I tried to read the slave Id of the slave device, but i am getting whatever i am se...
Posted on October 16, 2012 at 13:47Hello! I already found a library packet for using the STM32 USB as Virtual COM device. What I need is a library for a Virtual COM host, so I can connect a CDC device to my STM32. It's just for one specific CDC dev...
Posted on June 24, 2014 at 09:41Hi ST,I am using the STM32L151 processor on a custom made PCB. I use the I2C2 port as a slave and a GUI on my computer as master. The I2C1 port is setup as a master to control 12 slaves. The purpose is that the GUI sh...
Posted on June 24, 2014 at 23:21 Does anyone have such issue? /* TIM3 clock enable */ RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE); /* AFIO enable */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO | RCC_APB2Periph_GPIOC | RCC_APB2P...
Posted on June 24, 2014 at 13:09Hi allI am looking at programming the digital filter in the input stage of a TIM2 capture/compare channel.The filter is configured using the 'IC1F' bits in 'TIMx_CCMR1'The different bit configurations make reference t...
