Posted on April 13, 2014 at 03:03I got several lines of code in TIM1_CC_IRQHandler and need to know its exact running time because some real-time requirements.So when I run simulation I got a time span between the entrance and the exit of the ISR. I...
Posted on April 11, 2014 at 18:27In my programm I use uart4 with 115200 baud. I want to receive data from devices - so I configure UART in RxMode. I enebled only one interrupt source for itUSART_ITConfig(UART4, USART_IT_RXNE, ENABLE); My interrupt ...
Posted on April 12, 2014 at 08:14 Guys, Why can't I use 50MHz for SDIO ? GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; it worked only with 10MHz GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz; 1. /*!< Co...
Posted on April 11, 2014 at 15:27I wonder how to read all port simultaneously such as GPIOA0 up to GPIOA7 or the equivalent of arduino codes DDRA = B00000000; // sets Arduino Mega Digital pins 22(PORTA0) to 29(PORTA7) as inputs allBus = PINA; //re...
Posted on April 03, 2014 at 22:50Hi I'm working with the STM3240G-EVAL Board and trying to drive a BLDC Motor from Maxon EC-max 30 type 339923 (maxon.com) On the motor side I have Hall sensors and an encoder with 500impulses / turn, 2 channels A+B a...
Posted on April 11, 2014 at 13:09Hello, I am trying to use STM32 Nucleo board under Linux (tried Ubuntu 12.04 and 13.10). After connecting, a mass storage and ACM devices appear, mass storage for firmware uplading works, but I can't get the ACM devi...
