Posted on August 22, 2017 at 04:23I'm experiencing strange behavior of QSPI peripheral (or may be flash chip itself -- N25Q128 in SO8; chips are not shiny new, but never used; datasheet Rev. 8 July 2014): despite what is stored in NVCR/VCR registers...
Posted on August 24, 2017 at 16:11Is it possible to configure mac init as enable with cubemx, until now, it is always disable?macinit.ReceiveAll = ETH_RECEIVEAll_DISABLE;
Posted on August 24, 2017 at 16:06Can I use STM32F301 PA7 and Pb0 as normal AD input and disable opamp on STM32F301?I do not want to use internal opamp. Layout is already connected to PA7 and PB0 for current sensing and I want to use these two input...
Posted on August 16, 2017 at 21:39Hello,I'm working with STM32F0 and CAN communication, sometimes the CAN peripheral stops, doesn't send or receive messages.In the past I asked the same issue and the answer was that it could be the HAL_LOCK funtion ...
Posted on March 27, 2017 at 14:15Start with new CubeMX project, selecting NucleoF303ZE board. Enable 1 single ended channel on each of ADC1 and ADC3. Select Regular Conversion Trigger for both. CubeMX generates this line in MX_ADC3_Init(): hadc3.In...
Posted on August 24, 2017 at 15:33I played with PA9 on a DISCO-F4 board in its OTG_FS_VBUS function. This is a non-AF function, i.e. it's connected to PA9 all the time, and is supposed to be governed by USB_OTG_FS settings. I am not interested in OT...
Posted on January 25, 2017 at 20:33I seem to have an issue with receiving CAN messages. It is set up on an interrupt, but the interrupt only seems to fire once, and when I receive the 2nd message, nothing happens. There seems to be very little on ...
Posted on August 24, 2017 at 11:00Hello, I'm working on a project where I need to shut down my device, when it finished it's task. I use an STM32L443 microcontroller to control the device. The circuit was designed, that if happens a falling edge o...
Posted on August 21, 2017 at 14:58I'am trying sending speech data between two STM32F4 board with. I take speech data from PCM buffer. But the data that in PCM buffer is 16 bits. I need to send this data with UART. I know that, UART data register is ...
