Posted on June 12, 2016 at 08:51Hi!Im trying to use two EXTI on PE2 and PE3 pins simultaneously. Two push bottons are connected to these two pins with a pull-up resistor and a capacitor filter prohibitting debounce phenomenon. As shown in the code b...
Posted on June 08, 2016 at 05:37By the DM00032020 Reference Manual, when TIM2 is used as slave, it's trigger source can be IRT0 from TIM1, ITR1 from TIM8, ITR2 from TIM3, IRT3 from TIM4. But now, when choose trigger source ITR1 in the 'pinout' card....
Posted on June 11, 2016 at 20:40Hi,i m using 103RB nucleo board and keil compiler. I have configured code for one interrupt. CubeMX is generated code for handler also. But i m not able to find out how handler function is linked to vector address..I ...
Posted on June 11, 2016 at 01:55 Hi to all, I'm giuseppe and I'm new here, I've a big problem with the generation of pwm signal, in the code below i'm trying to create a pwm of 50% duty cycle in port PA0, the pwm would be of a period of 1s, s...
Posted on July 26, 2013 at 04:06I have been trying to make a slave I2C device communicate with my STM32F0 board, with no success. Can anyone give me an example code to config, init and send and receive data through the I2C bus.
Posted on June 11, 2016 at 12:51 I am using STM32L100This is put into deep sleep so pins are set to inputI am using FET to control power to external devices. this is connected to PB9 pulled down by 100k resistor. I find that the pin has a voltage...
Posted on June 10, 2016 at 11:45 Hi Guys, Want to ask for a quick bit of advice please. I have a STM32F407 running on a board that has been configured to count frequency (number of pulses per second - period and duty cycle are va...
Posted on June 09, 2016 at 22:16Hi.When read protection level 1 is applied to MCU, is it possible to read flash content somehow?I would like to store CPU status register, PC and some other variables into flash in case of hard fault. But MCU was read...
Posted on May 30, 2016 at 20:10I tried to migrate from STM32CubeMX 4.14.0 to 4.15.0 and from STM32CubeF7 1.3.1 to 1.4.0. I found some bug in CubeMX 4.15.0. It is not possible to set the clock for SDMMC using CubeMX. My controller is STM32F746ZGT6, s...
Posted on June 08, 2016 at 20:10 Hello everyone, I started with STM32F103 two days ago and I need to generate a PWM on GPIOB pin6 using TIM4. I need a PWM of period 20ms with a 1us precision (System Clock is set to 72 MHz) I have...
