Posted on December 11, 2012 at 09:30Hello all experts, I configured the TIM2 in my STM32F4 discovery board such that it gives me interrupts every 50ms. The code is as follows. ********************************* void TIM2_IRQHandler(void) { if (TIM_...
Posted on June 07, 2012 at 08:55I have read through many posts about SPI problems and configuration questions. I feel I have everything configured correctly, however I do not receive any data transferred across the MISO line. Below shows the confi...
Posted on December 03, 2012 at 10:23I am a beginner about the microcontoroller. I use STBee. I want to connect a STBee and a sensor(IMU 6DOF ITG3200/ADXL345). At first I want to let you display a value of the x-axis. Please teach a solution. &sharpi...
Posted on December 10, 2012 at 11:23Hello All, I am using STm32f2. I am using USART1 , i wnat to read and write some data to the device connected to USART1 I am setting 9600 as baud rate, i could see RXNIE RE,TE ,SBK,WAKE,PS,PEIE,IDLEIE,TCIE bits se...
Posted on November 20, 2012 at 17:00Is a basic reference design available for the STM32F4 family for things like power & programming header? I've looked at the data sheets but it seems that there are many different ways of programming, all spread th...
Posted on December 10, 2012 at 17:26Hi All, Is there a chance to get USB descriptor parts That implement USB Audio Class 2? Your suggestions please Abdul
Posted on December 07, 2012 at 09:40Hi, I have my own homemade board designed from a STM32F4 in LQFP100. It is supplied by +3.3V power. The JTAG is connected like that : - TMS : p.72 - TCK : p.76 - TDO : p.89 - TDI : p.77 - nRESET : /reset ie p.14...
Posted on December 10, 2012 at 01:57The manual says that the STM32 supports only 8 and 9 word length for UART.But I need 7 data bits.How can I configure the 7 data bits? #7-databits-uart-usart
Posted on December 08, 2012 at 04:37The device I am trying to connect to via serial interface requires constant clock ticking. I have enabled USART clock with USART_ClockInitTypeDef USART_ClockInitStructure; USART_ClockStructInit(&USART_Clo...
Posted on December 09, 2012 at 00:00 Hey again all, I have a multi master i2c setup, each and every device is also an STM32L. Each device is configured as below I2C_InitTypeDef I2C_InitStructure; GPIO_InitTypeDef GPIO_Init...
