Posted on January 22, 2013 at 08:32Hi, I am using STM32f4discovery board and am trying to write a code which will take moving average of accelerometer data. For this purpose my average variable have to be in floating point. But during initialization...
Posted on May 10, 2014 at 14:12 Hello, I am having a strange problem where my UART1 remap is getting dependent on I2C1 remap. Following is the scenario: If I configure only UART1, remapped to PB6/7 it does not workWhen I enable the rema...
Posted on May 09, 2014 at 22:09Hello everybody.I want to solve a read problem in a special hardware, the configuration of each pin is input:RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA | RCC_AHB1Periph_GPIOB | RCC_AHB1Periph_GPIOC | RCC_AHB1Periph_GP...
Posted on May 09, 2014 at 19:14I have been reading the ''PM0075'' Programing manual STM32F10xxx Flash memory micro-controllers and I am trying to understand the mass erase feature. In the manual it states:''Bit 2 MER: Mass eraseErase of all user pa...
Posted on April 29, 2014 at 20:24I'm working on the STM32F439-EVAL. I've created my own project using STM32Cube and am able to use SWO output and see the logs on the IAR terminal IO window (I'm using IAR). In order to compare some of the bootup proc...
Posted on May 09, 2014 at 15:48Hello, i'd like to do output compare on four pins: PE13, PE9 (LEDS), PA10 and PA12. Everyone works except PA12. I tried to do that with TIM16 and TIM4 with no luck. And i reconfigured the channels, i understand how the...
Posted on May 09, 2014 at 14:34I have been looking in the stdlib libraries (v 1.0.2) for the STM32F401VE, and there does not seem to be any support for SPI4, even though it is listed as existing in the datasheet and reference manual. What gives?Have...
Posted on May 09, 2014 at 15:48Hi, Has anyone started using V1.0.7 Keil.STM32F4xx_DFP.1.0.7.pack? We are considering to use it as a part of medical product development. I also do not see any example codes as a part of this pack (particularly requir...
Posted on May 08, 2014 at 17:48Simple question - should be answered in datasheet, errata sheet, or ref manual but I cannot seem to find it. I am wondering how much ADC readings drift relative to the reference voltage with temperature. If I have a co...
Posted on May 06, 2014 at 07:17Is there a tutorial or lecture series for beginners working with a STM32F3 demo board? I have programmed simple project boards like Arduino, but not anything like the STM32 boards. I have tried to work backwards from t...
