Posted on February 18, 2015 at 12:42 Hello everybody, I have a problem with I2C on STM32F4 I communicate with a touchpad controller: everything is OK, I can configure this I2C controller and get its datas. But when I communicate it...
Posted on February 18, 2015 at 14:14Hi, i am trying how to connect stm32f429 to lcd screen. Screen supports de and sync mode. I don't know what mode should i use. Know,that stm32f429 has embedded tft controller, does it support de mode?
Posted on February 18, 2015 at 10:07I use a STM32f4vgt6 and I configured the PWM to control a DC motor. The problem is that when I measure the output PWM tention I notice that it does not exceed the 3V. When I connect the VDD pin to 5V, the problem ...
Posted on February 16, 2015 at 12:59Hello all,I am having problem in updating the code to STM32F103ZCT7 using ST link V2.I am getting the error as ''Can not connect to divice; Internal Command Error''I am using three pins SWDIO, SWCLK, NRST. I have ...
Posted on February 12, 2015 at 09:28Dear all, Do you know if it is possible to get from a single pin a capture PWM input (and get the frequency) and on the same pin, to be able to count the number of pulse ? Currently I have ''capture PWM input'' on...
Posted on February 17, 2015 at 17:36Hello, I want to have a fast interrupt with the STM32F429 at 168MHz. I use EXTI interrupt who toggle an gpio for test. I measure the time with a scope between the exti pin front and the gpio output front. I made...
Posted on February 17, 2015 at 14:5802/17/2015STM32 users can now choose from three IDEs from leading vendors, which are free of charge and deployed in close cooperation with ST. Users can choose between: CooCox CoIDE: support all STM32 devices b...
Posted on February 17, 2015 at 14:10Hello,the STM32F4 Library has an example for DFU over USB (usbd_dfu.c). However, it is implemented the DfuSe way, so it does not follow the DFU standard and can't be used with software which follows the standard. ...
Posted on February 17, 2015 at 11:08I have successfully made it work with STM32F072 board using the dac, dma, tim6. The timer is responsible of triggering the dac and there is a double buffer mechanism when dma finish handling the current buffer. ba...
Posted on February 17, 2015 at 09:12Hi, I couldn't find a value for the lifetime of the microcontroller. I just found these very big and complicated stuff in the datasheet, but no value or something. Maybe somebody could help me out. I expect someth...
