Posted on May 29, 2015 at 19:48In the datasheet of STM32F407 it is stated (Table 4, 2.2.21), the max speed for TIM1 is given with 168MHz, whereas TIM2-5 only run with max. 84MHz. This is quite clear, as TIM1 connects to APB2, running at max. 84MHz, ...
Posted on June 08, 2015 at 08:25hi every one i wrote a c project for a stm32f103ret6 in keil & download it with jlink v8 to mcu ,it work fine. but know i want to program same project to the stm32f103rbt6 but it dosent work correctly i download the p...
Posted on June 16, 2015 at 09:53Hi all, We had procured some sample STM32F105VCT6 ICs and were able to program the device through the serial port (USART1). Later we procured some from a local vendor. These are not getting programmed. On searching th...
Posted on May 20, 2015 at 14:40i want to make two pulses tdelay1 and tdelay2 with different pulse width after rising edge of an external signal(let's name it sync pulse) also i want to calculate starting time of many signals so i decide to use timer...

Posted on May 30, 2015 at 00:30Here are a few parameters that are not filled in by the generated code that are then caught by the 1.6.0 library code:HAL_TIM_ConfigClockSource needs these values to be filled in with something:sClockSourceConfig.Clock...
Posted on June 16, 2015 at 12:35 This is not a question, just something I developed and I wanted to share with the community. I am fairly new to ARM and STM32 and perhaps there is some things I haven't come across yet. I realise that many...
Posted on February 20, 2014 at 18:00I am using a STM32F4 as a SPI slave. The STM32F4 receives a packet of data over a USART line and must have the data immediately available for use in the SPI communication. I am using a DMA Tx memory to peripheral ...
Posted on February 18, 2014 at 09:01 Hello all, I've run through couple of SPI DMA threads here, but I didn't find what I was looking for... On my STM32F103 I'm sending data to host over SPI: - my STM32 acts as SPI slave - SPI trans...
Posted on June 16, 2015 at 10:45Hi, I want to use the state of a GPIO Pin (It is driving a chip select on an SPI device) to determine that the SPI transfer has completed. I do know about the callback on the CMSIS code, but I'd prefer not to use tha...
