Posted on November 07, 2017 at 15:58HelloI have a problem with the Timer2 on STM32F767.I use the Timer2 as simple timer in Countermode Down. With this timer I want to realize a countdown to start another process once after the underflow interrupt ha...
Posted on November 08, 2017 at 09:15On STM32F777 I have configured TIM2 as encoder counter with a period of 8192 (i.e. the CNT will wrap at 8192, see ARR register).Everything works as expected until I reset the CNT by setting TIM2->CNT=0. In this c...
Posted on November 03, 2017 at 22:27Hi ST,I have just downloaded 'STM32Cube_FW_F4_V1.17.0' and found it has 'libarm_cortexM7l_math.a' in CMSIS folder.There is no cortexM4 file so I am confused if M7 library is compatible with M4.I think this is a mi...
Posted on November 08, 2017 at 05:58Hello,I have a hardware using STM32F303RCT6 and Can Transceivers TI SN65HVD232. I want send data from Canbus to Terminal using USART1 and blink LED at GPIOC_PIN_9. I just used ARM, and i used to STM32cubeMX to con...
Posted on October 28, 2017 at 12:45 I have my own product board with STM32L073VBT6.The power comsumption increase to 10mA (an other is 4mA) when enter low power mode.So I had removed all other chips only left the STM32 and found out that the MCU cos...
Posted on November 06, 2017 at 20:47I am using the STM32F427 micro and a Keil compiler. I have ADC1 and 2 configured for dual simultaneous mode and scanning through 12 conversions. Three ADC conversions for each of four different dual ADC channel in...
Posted on November 07, 2017 at 21:22hello,i'm working at a project. it's a digital effect processor for singing, something simple just some delay and reverb, but i don't have enough sram memory on the stm32f407...the conversion is on 16bits at 48khz...
Posted on November 07, 2017 at 20:25So, I have 5 TDM data slots being used in my SAI1 master TX using circular DMA. I have a buffer that is 10240 bytes in size (5*1024*2). So, to start the TDM signal, I call: HAL_SAI_Transmit_DMA(&hsai_BlockA1, &D...
Posted on November 06, 2017 at 14:46Hi,Is there an evaluation module for the above said MCU- to test its capabilities or to add other control modules?What kind of software support will be provided if in case we choose this MCU for our product?#stm32...
Posted on April 08, 2017 at 00:00I am trying to implement UART in DMA mode to transmit a simple string every time a push button is pressed.So I have used CubeMX to generate the code and I have configured UART2 TX DMA in normal (not circular) mode an...
