Posted on June 29, 2017 at 16:01Configured USART1 of mcu to 500 kbit/sec using STM32CubeMX Version 4.21.0.Code created by Cube seems to be correct.Measurement shows that bitrate is 250 kbit ( a 10 bit character needs 40 µsec).See Attachements.USART...
Posted on June 29, 2017 at 08:03Hi,I prepared several project files for a few DISCOVERY boards (I shared examples for STMF429, STM32F746, STM32F412, etc), but this time it seems to take more time than I expected. Maybe someone from you guys already ...
Posted on June 22, 2017 at 20:13Any reason not to drive 6 L6472 daisy chained devices directly from the STM32F303 SPI bus? Running at ~1MHz.
Posted on June 27, 2017 at 12:54I recently bought a X-NUCLEO-IDB04A1 and wanted to use it with Arduino. How do I go about it ? Please help me out.My aim is to collect the sensor data from http://www.st.com/en/ecosystems/x-nucleo-iks01a1.html and sen...
Posted on June 22, 2017 at 14:35Hello,the Ethernut (http://www.ethernut.de) STM32 Ethernet driver from svn head (/sourceforge.net/projects/ethernut/files/) works reliable for F107/F2/F4 and F74. However for F767 Revision A chip (no Rev Z chips avail...
Posted on June 29, 2017 at 06:35I am looking for a method to build uart rx/tx circular buffers for STM32L476 which communicate using DMA. In 40.5.2 of http://www.st.com/content/ccc/resource/technical/document/reference_manual/02/35/09/0c/4f/f7/40/03...
Posted on March 22, 2015 at 17:50I found the problem. When I quickly connecting/disconnecting USB device(LS HID mouse) from STM32F207 USB host FS port the occurs another situation: USB constroller stop generate host channel and/or port/disconnect ...
Posted on June 27, 2017 at 15:02Hi.I'm trying to use DMA to drive PWM output for led effects. MCU write seems to be OK, however there's few very weird consepts related to DMA configuration I don't seem to be able to wrap my head around.void HAL_TIM...
Posted on June 28, 2017 at 03:19Dear allUseing CAN1 of STM32F205, 32-bit Mask Mode filter, filter bank 0-13 work all right for now. Then I am trying to configurate CAN2SB = 28d, for letting CAN1 use all 28 filter banks.But it doesn't work, here is m...
Posted on June 26, 2017 at 01:13I am experiencing some issues with the ADC on my L0. I configure it with PCLK as the input clock in CKMODE, start it up, and take a sample. Everything works fine. I then decide to set the oversampling mode (which is i...
