Posted on May 02, 2016 at 15:12A Nucleo144 landed on my desk. As with every new board, there has been a stare-and-criticize session, and somebody noticed four pads at the four corners of the chip, at a 45 deg. angle. They are roughly of 0805 size an...
Posted on May 02, 2016 at 11:03hi I have problem with adc sampling and controller calculating at each period of sampling(each sampling time) .I fond this from st,com . I have some questions : 1.what is the meaning of first line exactly and how I ca...
Posted on May 02, 2016 at 08:34Hi, in chapter 1.1.4 of AN4661 is descriped that if DSI is not used at all then: ''The VDDDSI pin must be connected to global VDD'' There is also written: ''The VDDDSI pin must be grounded.'' Is this a typo? What is c...

Posted on April 19, 2016 at 17:38Hello, We are using the STM32F439 in our application.While using the simulation with IBIS model (Hyperlynx), we have discovered undershoots on FMC pins.The voltage in undershoot is about -866mV and the current limit ...
Posted on April 29, 2016 at 05:08Everything is working, just not as I thought it should be. As the logic analyzer shows below, the main loop is interrupted for almost the same amount of time the I2C operation takes. Notes: - I'm using Cube generated...
Posted on May 02, 2016 at 04:09I am using the latest STM32CubeMX (V4.14) and the latest version for the STM32L4 family (version number escapes me right now) and I am trying to understand how to properly use the Discovery board to act as a USB Audio ...
Posted on October 28, 2015 at 14:57Hello everybody, with this code, no matter what I do, I always get 4095 (max). I've tried looking at Clive examples or IAR's examples I just can't see it. Could someone take a look and see what am I missing. I need...
Posted on May 01, 2016 at 17:49Hello, I am stuck in implementing USB composite (VCP+MSC) using FS-Device_Lib_V4.0.0 (STM32L151). Individually both works but when I try composite VCP+MSC, MSC works well but PC can't communicate via VCP (although it c...
Posted on May 01, 2016 at 17:49Hello ST team, I like to see a critical section implementation similar to atmel avrlib ATOMIC_BLOCK implementation. example: ATOMIC_BLOCK(5) { uint8_t status get_spi_device_info(); if(status == 0) return; d...
