Posted on May 02, 2016 at 19:45Hello!I would like to ask, if anyone knows, if there is a DSP instruction for Cortex-M4, which would calculate x*x + y*y. I saw that there are some quite complex instruction which are intended for similar calculations,...
Posted on April 16, 2016 at 16:40Hi all, I have trouble getting a LDC Display on the STM32F429 FMC to work in 8080 Mode. I use the same hardware connection like withe STMF4Discovery Expansion Board and the STM32F4DIS-LCD Modul.FMC_D0 (PD14) -> LC...
Posted on April 22, 2016 at 11:07Hello communityI am having troubles when doing DMA with USART on an STM32F030. Thanks in advance to anybody will help.Not sure if i did the homework correctly so I need someboody to check thisTMy application aims to ...

Posted on April 22, 2016 at 10:39 Hello, I'm starting out using the CubeMX software to configure my NucleoF103 and one of my first test applications was the I2C bus. I got it working by polling. Then I started looking into the DM...
Posted on May 02, 2016 at 16:41Hi, I have a conceptual question about DMA data transfer and timers. I'm using an STM32f103RBT6 and would like to output a square wave signal that is non repeating. What I would like to do is to create a buffer of ca...
Posted on April 30, 2016 at 16:20I'm using the STM32F446 nucleo board and am trying to simply trigger a DMA transfer onto gpio when an OC triggers. Although I've done this many times on other boards (particularly F0 boards) I cannot figure out why i...
Posted on May 03, 2016 at 06:34Greetings allI'm using HAL_TIM_PWM_ConfigChannel() to set the Pulse value for my PWM output but I want to modulate it (think IR LED on/off keying) so I'm currently using HAL_TIM_PWM_Start() and HAL_TIM_PWM_Stop(). The...
Posted on May 02, 2016 at 10:50Hi. I'm trying to set LTDC clock to 54MHz but I am measuring 385.7kHz instead of the true value with oscilloscope. Scope has 350 MHz bandwidth. I'm configuring the PLLSAI with std_periph libraries; RCC_PLLSAIConfig(432...
