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...
Posted on May 02, 2016 at 17:36Hello,As far as we know, is it possible to get CAN bus master running from HSI clock at 1Mbps. However, is this reliable enough? should we go for a HSE clock scheme?Thanks so much. #stm32 #canbus
Posted on May 02, 2016 at 15:12A Nucleo144 landed on my desk. As with every new board, there has been a stare-and-criticize session, and somebody noticed four pads at the four corners of the chip, at a 45 deg. angle. They are roughly of 0805 size an...
Posted on May 02, 2016 at 11:03hi I have problem with adc sampling and controller calculating at each period of sampling(each sampling time) .I fond this from st,com . I have some questions : 1.what is the meaning of first line exactly and how I ca...
Posted on May 02, 2016 at 08:34Hi, in chapter 1.1.4 of AN4661 is descriped that if DSI is not used at all then: ''The VDDDSI pin must be connected to global VDD'' There is also written: ''The VDDDSI pin must be grounded.'' Is this a typo? What is c...

Posted on April 19, 2016 at 17:38Hello, We are using the STM32F439 in our application.While using the simulation with IBIS model (Hyperlynx), we have discovered undershoots on FMC pins.The voltage in undershoot is about -866mV and the current limit ...
