Posted on October 21, 2012 at 19:43I have a problem with programming a Stm32f0Discovery board,When i have a code built and the board connected with STM32 ST-LINK Utility, and i click program it says: No Stlink detected.What am i doing wrong,
Posted on October 22, 2012 at 14:13I am trying to make i2c driver with stm32f0 cotext M-0. I am a very newer. I am reading specification, RM0091 and following the instruction. I set STM32f0 i2c as a master and I followed the RM0091 (24.4.9 I2C maste...
Posted on October 22, 2012 at 13:20Hi all,I bougth a STM32F2 evulation board and iam trying to use high speed IO's but i didnt succes. here is the code;RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOF, ENABLE); /* Configure PG6 and PG8 in output pushpul...
Posted on August 06, 2011 at 02:56I want to use low power mode (STOP). i put two configurations here... In the first configuration i am putting 2 STOP mode but first runs... When i wait the same external interrupt despite i enable this, i cant run b...
Posted on October 19, 2012 at 17:49I'm trying to use the ADC on an STM32L1xx to read a single channel with a sample rate based on TIM2. I plan to use a double-buffering scheme, so I want to set it up to DMA into a buffer with half-complete and full...
Posted on October 16, 2012 at 17:14Hi all, I'd like to make 2 STM32F407 share 1 external RAM as a common memory. Chip #1 would store some data in RAM for chip #2, then stop all accesses and signal to #2 that there is some data for him. Chip #2 would...
Posted on October 19, 2012 at 18:51The STM32L1xx reference manual has this text in the DMA section: The 7 requests from the peripherals (TIMx[2,3,4,6,7], ADC1, SPI[1,2], I2Cx[1,2], USARTx[1,2,3]) and DAC Channelx[1,2] are simply logically ORed...
Posted on October 19, 2012 at 16:47Hello, I am having problems with the syStick timer. The handler for sysTick stops being called after one or two interrupts from TIM3 (set < 1Hz). The TIM3 interrupt has no problem (LED keeps toggling). I started ...
Posted on October 18, 2012 at 17:56Hi,I'm having a bit of trouble configuring the SPI2 clock frequency on an STM32F407VG, or perhaps I am confused as to how it works.Using a 25Mhz external oscillator, boosting up to system clock frequency of 168MHz....
Posted on October 19, 2012 at 10:18Hello All, I am using STM32Fs series and I am writing a code for SPI2 . I have to read and write from the slave device. I have to read the data when RX buffer is full and write data continuoulsy to another device....
