Posted on January 16, 2017 at 10:17Hello,I have added an audio task to the stm32f746g discovery project netconn udp echo server (Freertos + lwip ).The audio task is very simple.I capture the audio data from the microphone and i play it back.The aud...
Posted on December 29, 2016 at 15:53Hi,I'm quite new to STM32 and Cube HAL. Hardware is custom, mcu is STM32F042G6Ux, created initial code with Cube MX. IDE is SW4STM32.The issue is that the ADC value is alternating somewhat between two values (roug...
Posted on January 15, 2017 at 14:15Hi,I am working with Nucleo-64 board STM32F401RE.I connect 2 similar devices to the same computer and the name under windows device manager is identical (except to COM port).Is there any way to edit STM32F401RE:1. ...
Posted on January 12, 2017 at 06:10I am new to ST and need support. I want to use USB in my project but I am unable to find a example to use usb as a storing device. Please any one share complete example or any tutorial.Thank you in advance #clive1...
Posted on January 13, 2017 at 13:29Hi, i have problem, i can's understand, can i connect STM32F407 MAC(RMII) to MAC(RMII) KSZ 8863 without PHY level. In STM datasheet shown only RMII->PHY connection. I use lwIP lib, but it need PHY level. What can i...
Posted on January 15, 2017 at 21:27I am working with a Nucleo L031K6 board and my application showed strange behaviour that I could finally track down as two C variables sharing the same memory location....Not being a specialist in neither C nor the...
Posted on December 10, 2016 at 22:07I am testing the microSD card. The weird thing is that it works well in debug mode, but doesn't work in normal mode.I set the breakpoint to a line at the very end in debug mode, before which the operation of micro...
Posted on August 02, 2016 at 18:05Please add GNU ARM Eclipse, with a reference to http://gnuarmeclipse.github.io, to the list of free, open source, development environments with strong support for STM32 devices.Regards,Liviu #free-development-ide...
Posted on January 15, 2017 at 08:37Hello,I'm currently trying to write a library for the stm32f4 to output dmx via the uart. With other mcu's I've done this by generating the required start code etc by changing the port baud to a specific speed, sen...
Posted on January 14, 2017 at 14:30I have stm32 gpio pin connected through 5k resistor to the 12V supply. What voltage can I expect on the pin depending on the gpio configuration and processor model? Is there any internal clamping in the MCU?Do I ne...
