Posted on April 11, 2016 at 19:07I am an engineer at a startup developing a new flight controller for hobby aerial vehicles. We are using the STM32F103RET6 microcontroller. I am currently having an issue using I2C2 and UART4 simultaneously.We rece...
Posted on March 29, 2016 at 21:05Is there some bug tracker or feature request branch on forum? How can I leave feedback for this software? Anyway, here I'll post my proposition. CubeMX generates initialization of periphery like this: /* Initialize...
Posted on December 16, 2015 at 12:26Hi, I noticed this after the latest 4.20.0 update. This is experienced on a CubeMX project creation (Keil uVision). I think, the naming for the Hard Fault ISR function is wrong in stm32fxx_it.c file. I think it sh...
Posted on November 28, 2015 at 18:00Hello all, I made a new project with latests CubeMx 1.9 for stm32f4 My problem is that the autogenerated code does not trigger the ISR. I found out that when I __HAL_RTC_WAKEUPTIMER_CLEAR_FLAG(&hrtc, RTC_FLAG_WUTF...
Posted on February 13, 2016 at 22:31Hello, in the new CubeMx STM32F4 1.11 library there is a new bug introduced. There is this new feature:Add new define USE_SPI_CRC for code cleanup when the CRC calculation is disabled. The codegenerator generates...
Posted on April 08, 2016 at 14:56Hallo.I need to combine PGA and ADC for cases when the analog signal becomes very high or low.Is there an example how to do that?Additionally I would like to use one ADC for two synchronous signals by scanning two in...
Posted on April 12, 2016 at 13:12Hi All New to STM32 but not new to MCU's (Have done projects on TI, Microchip, Atmel, etc) I'm busy to evaluate Contiki on STM32L053 Nucleo to compare to the MSP430 implementation of the Contiki stack. On MSP430 I h...
Posted on April 04, 2016 at 09:06Hello. I use STM32F407VET6 device. I try to use USB Host (Mass Storege Host Class). Project (for IAR) generate correctly. I try to compile for C++ and have ( Error[Pe067]: expected a ''}'') multiple errors. I use fri...
Posted on April 12, 2016 at 08:56We're using the STM32CubeExpansion_BLE1_V2.5.2 on a STM32L4-Nucleo + BlueNRG-Expansion. It comes with low power manager drivers. The STM32L4 switches between RUN and STOP mode every ~ 1 sec. It uses RTC wakeup timer ...
Posted on April 09, 2016 at 22:47I'm designing a product that uses the STM32F446. The reference manual states that Vcap is increased to 4.7uF (from 2.2uF for the F405) on page 15 and later on page 72 (power supply scheme) it lists 2 x 2.2uF caps on ...
