Posted on November 11, 2017 at 15:07Hello! I try to use a TIM1 in a PWM bipolar mode (chip is stm32f030f4p6).I use CubeMX . But after compilation of the project the timer doesn`t work. Must I write my own code for start this timer? Thanks a lot for ...
Posted on November 09, 2017 at 08:07I have a problem on negative output when use the TIM8 with 6 complementary output (same on TIM1).the problem is the polarity setting on Negative channel not work if not enable one of the output (positive or negati...
Posted on November 10, 2017 at 05:42 Hi, I used STM32F103 MCU before and was new for STM32F3x MCU. My stm32f103 codes was migrated to stm32f302 codes for stm32f302r8 MCU.The code problem is that after power on, MCU turned on LED normally and prin...
Posted on November 10, 2017 at 23:09I'm working with a Nucleo F767ZI and BSP F7 V1.8.0.When setting up a pair of ADCs to do dual simultaneous conversions, DMA access mode disabled and mode 2 are the only choices. Access mode 1 and 3 are missing fro...
Posted on March 28, 2016 at 23:29Recently the STM32F407 discovery board changed part numbers from STM32F4DISCOVERY to STM32F407G-DISC1. The old boards could be powered directly via the 5V pins on the headers, or via a USB wall-wart, but the new boar...

Posted on November 10, 2017 at 21:03Hi, I need to calibrate my RTC crystal that is drifting about 7 seconds every 18014 that according to my calculations is about 389 ppm. I Tryed to perform the calibration with the following initialization code, bu...
Posted on November 10, 2017 at 18:21I have an STM32F103C8T6 uC and an ASIC chip with memory. They communicate with SPI interface, ST being the Master device. On the uC lies a Firmware by the vendor of the ASIC device. I have been trying to shape it ...
Posted on November 09, 2017 at 15:07Hi,i use a STM32L496.I configured the SPI to communicate 8bit but it always generates 16clk e 16bit data.SPI : MASTER- halfduplex 2wire(1clk , 1Mosi/Miso) /* Enable clock for SPI2 */ RCC->APB1ENR1 |= RCC_APB1ENR1_...
