Posted on November 29, 2015 at 03:54I have a simple timer interrupt based GPIO toggling code to be tested on STM32F401 discovery board as shown in this link http://codepaste.net/fhmh2v . The problem is this code doesn't toggle the LED/GPIO. I set a ...
Posted on November 29, 2015 at 15:58Hi all,I just received my new layout based on STM32F2 and I can't upload via SWD (Vlink V2).Always the same mistake : Can't reset the core...I checked VCAP1 & 2 at 1.2V and all SWD lines.But perhaps I made a mista...
Posted on November 27, 2015 at 03:50Please help,I was programming my STM32F4-Discovery with an ''ADCInterleaved'' code (from template) using Keil and suddenly my board get disconnected from my PC. The program load was smooth though, but after i want...
Posted on November 25, 2015 at 21:59I am confused with the HAL I2S libraries as there does not seem to be support for 16bit stereo (2 channels).I admit, I am a bit new on I2S but I suspect that with 44100 sampling frequency with two channels of 16 b...
Posted on November 28, 2015 at 19:06Hello, I have a question about voltage reference of DAC on STM32f407. Is it possible to change voltage reference of the internal DAC at 0 to 2.5V.And the second question: is it possible to programming this change ...
Posted on September 04, 2015 at 13:33NOTE: edited by moderator on Oct 6th, 2016I'm working on my board to erase or download the program to the MCU. my MCU is STM32F103RBT6 and my programmer/debugger is J-Link. I have wired up the JLink to MCU like t...
