Posted on October 14, 2016 at 01:13Hello, I am using STM32F4 Discovery board (with STM32F407VGTx) with the latest HAL libraries. I am interested in varying PWM pulse width (duty ratio) in a while loop. Looking at MX_TIM3_Init function (also attached...

Posted on October 13, 2016 at 00:41Hello, Will the following generate a 50 Hz pulse?(Since htim3.Init.Period = 19999 which I think equates to ~20ms) htim3.Instance = TIM3;  htim3.Init.Prescaler = 83;  htim3.Init.CounterMode = TIM_COUNTERMODE_UP;  ht...

Posted on October 12, 2016 at 19:24Hello, When using USART, is stm32f4xx_usart.h the only file I would need to include?I currently have this:#include ''stm32f4xx.h''#include ''stm32f4_discovery.h''#include ''stm32f4xx_usart.h''#include <string.h>But...

Posted on October 12, 2016 at 14:46Hello, I was working off of TIM_PWM_Output (Peripheral_Examples from FW_V1.1.0) and would like to add UART connection to it.How do I initialize UART if using FW_V1.1.0?Thanks, Sel 

Posted on October 05, 2016 at 02:31Hello, If a pin is configured as Push Pull, can we still specify a pull up resistor to go with it?(Is the pull up used to avoid floating conditions even in Push-Pull configurations?) /**USART2 GPIO Configuration   ...
