Posted on January 02, 2015 at 11:44HelloI have 2 questions :1 - According to this library and sample examples , HAL_Init() function is called at the start of the main() that configures the systemtick timer for generating 1ms interrupts , but after t...
Posted on February 28, 2015 at 03:34Hi all,I am using STM32F103RCT6 and CP2102 as UART controller driver.I have problem with USART when I use SysTick Timer to generate 1us Delay.The problem is that when I configure SysTick at frequency 1Mhz, the pro...

Posted on February 28, 2015 at 10:47Hi. I'm trying to set the spi at max speed (in theory 30mbit/s spi in stm32F2), but I just get 15mbits on SPI output.This is my spi initialization (for SPI3). I'm using DMA to transfer a buffer, but in theory that...
Posted on February 28, 2015 at 09:18 I have checked the demo in: STM32Cube_FW_F4_V1.3.0\Projects\STM32F4-Discovery\Examples\UART\UART_TwoBoards_ComIT I setup same configuration following STM32CubeMX and I can Tx but I can't Rx. Instead...
Posted on February 27, 2015 at 08:20Hi.To start i'm using STM32F207I have a 15Mhz signal (that sometimes is enabled and sometimes it is not) connected to TIM3 ETR. I just want to count pulses and generate a pulse after few of this clocks (from 1 to ...
Posted on February 27, 2015 at 19:44Hi all,I'm doing some testing with STM32L151, and I'm trying to send a bulk of data over SPI.I'm using SPI in interrupt mode, my CPU is set to 32MHz, SPI is set to 16MHz.When I send a byte, I'm waiting for a SPI_I...
Posted on May 27, 2012 at 10:40Hi,I am using the STM32F107 micro, and tied an SD card into its SPI3 remmaped pins. As i saw in the datasheet the RXNE bit responce after the trasnmission is at worse 1 bit clock in duration. As you can see from the DS...
Posted on February 27, 2015 at 17:54Hi, do ST provide an mcal layer for use with an Autosar OS on the STM32F4 range of micros? Thanks Andy
Posted on February 27, 2015 at 11:12Hello everybody, Im working on a project with a nucleo-F103RB with the IDE EM::Blocks and I have some issues with the Systick Timer. I read some relative post but none of them solve my problem. This is the way i c...
