Posted on June 28, 2017 at 13:34Hello. My application hangs after setting the ROP to LVL1 and resetting the whole device. I have found some people had this issue as well and power cycling helped (which is my case as well). But it is kind of an incon...
Posted on November 10, 2017 at 14:09Hello, I'm working with STM32F4 Discovery Board and trying to generate a 16-pulse signal with variable duty cycle like this on the picture below.Currently i can generate 16 Pulse through One Pulse Mode. However i ...
Posted on November 10, 2017 at 07:40 Hello. I need read temperature from internal sensor. But when i use code from examples, all time i have result more then 30 degrees of Celsius(~1760 - factory calibration value, ~1740 - ADC value in cold st...
Posted on October 26, 2017 at 15:57I'm using STM32F0 Discovery and need to store values in SRAM when MCU is powered off.I already removed SB1 shunt. Then VBAT is not powered from VDD but pin3 of P1 (VBAT pin supplied with 3V).When I turn off my STM2...

Posted on November 07, 2017 at 06:31I am using STM32F0308 Dicovery Board. I want to use external interrupt on PIN11 of PORTB. Problem is that I am not able to invoke the PORTB. Microcontroller is still uses PIN11 of PORTA. I know that pins of ports ...
Posted on November 10, 2017 at 09:52hii have a problem in pwm.i want to generate a pwm signal by nucleo stm32f103rb board,i use keil for the compiling,and i don't get the pwm.this is my code :&sharpinclude <stm32f10x.h>TIM_TimeBaseInitTypeDef TIM_st...
Posted on November 10, 2017 at 07:28I have used STM CubeMX and Keil u5 and i have interfaced a Potentiometer with Nucleo STM32F103RB Devkit so i am getting ADC Values using these function, ' HAL_ADC_Start_DMA(&hadc1,ui32ReadADCBuffer,3); ui32...
Posted on November 10, 2017 at 09:29Hi,In the application I'm currently working with, it is possible to have several devices (UART controlled) but it is not known if the device is connected or not. I use USART3, UART4, UART5. I measure each USART/UA...
