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...
Posted on February 27, 2015 at 05:59my application works perfectly in debug mode.as soon as i get disconnected from debug mode and tries to restart application by pressing reset button ,lcd goes white on stm32f429.i mean i dont know whats happening ...
Posted on February 26, 2015 at 05:00Hello. I created MODBUS firmware bootloader and it works good, but when I upload main firmware it does not program flash. Bootloader is compiled with base 0x08000000 and uploaded by JTAG. Then main firmware is com...
Posted on February 27, 2015 at 11:58 Just wondering if it's possible to send/receive I2C data using re-starts instead of Stop/Start. So I transmit data with: if( HAL_I2C_Master_Transmit(&hi2c2, ADDR_DS, i2c_data, 5, 1000) == HAL_OK...
Posted on February 27, 2015 at 10:21We are using TIM16 for pwm audio output. We want to make it more efficient by using DMA. The DMA triggering is done using TIM6 which controls the rate.I would use a direct access to TIM16 by configuring DMA_Perip...
Posted on February 26, 2015 at 09:35I use cube1.3.0 lwip on STM429. It can work and ping ok in release mode. But in debug mode when I use keil and st-link, it always timeout. I have tried ping and TCP recv/send, it's response 2-3 seconds. Link bel...
Posted on February 26, 2015 at 18:51HI.I have a board with stm32f407. I Have ported UCOSII on it and in one of tasks enable USART3 and its interrupt handler. USART works correct at sending but my probelm is this:I can not recieve any thing on my in...
Posted on February 05, 2015 at 19:44The application is to use a STM32F4, but not allow the core to enter any level of ISR at the time it's supposed to service a TIMER interrupt. The application needs the TIMER events to be repeatable down to clock c...
