Posted on June 21, 2017 at 13:00Hi,I am using two I2C busses with STM32F411 uController (I2C1 and I2C2) and I need to implement a pass-through between those two: messages coming from I2C1 shall be forwarded to I2C2 and viceversa.Is there any example...
Posted on June 19, 2017 at 12:46Hello, I am trying to compile the example project provided by ST for the X-CUBE-SPN7 motor control kit. The kit includes a Nucleo-F302R8, X-NUCLEO-IHM07M1, a brushless motor and an ACDC power supply. I proceeded to do...
Posted on April 21, 2017 at 15:58HI Iam interested in dsp and audio processing using STM32F4 and STM32F7 and I found STM32 AUDIO 100A app note . It refers to an X-CUBE-AUDIO-F7 firmware library but I cant find it anywhere. Can someone help me please...
Posted on June 21, 2017 at 10:39I'm looking to use the STM32L151 in low-power run mode with I2C. The datasheet says I2C can be used in this mode (DocID022799 pg.17) but to operate in low-power run mode, the system clock needs to be the MSI set to 13...
Posted on February 19, 2017 at 18:58Hi,I need to change sampling rate from 48kHz to 16kHz and came across SRC236 which is part of X-CUBE-AUDIO-L4 library. Unfortunately there is no source or download link avalible anywhere on ST website. I found onl...
Posted on June 20, 2017 at 13:47Hi allI'm using a STM32F405RG with CubeMx and Keil (over SWD for flash & debug)it's embedded on a 3party board that (obviously) we didn't designunfortunately they didn't put the USB - VBus sensing pin on PA9 as it sho...
Posted on June 21, 2017 at 08:37HelloI'm using the STM32 Window Watchdog (WWDG) to make sure my firmware behaves, as it should. My problem is, as soon as the MCU wakes up from STOP-Mode, the WWDG makes an immediate reset. As i saw in the reference m...
Posted on June 20, 2017 at 00:07 I've been working on a board based on the STM32F3 with a large number of ADCs and other peripherals. I'll also be using multiple I2C and UART peripherals; the responsiveness of I2C and UART is much higher than the...
Posted on November 06, 2015 at 04:33 I am using interrupt based UART IO (no DMA). HAL_UART_Transmit_IT function sets EIE bit in CR3 register. According to STM32F407 datasheet (and real behaviour), this generates interrupt only in multi buffer...
Posted on June 16, 2017 at 02:07Hi there, Has anyone been considering migrating from the STM32F4 chip to the upcoming H7 chip, and how involved\possible that process might be? My specific chip is the STM32F4ZIT6, but I'm curious about others' experi...
