Posted on June 29, 2017 at 13:50Hello ST engineers,According to the MCU (STM30F303RCT6) datasheet, the absolute maximum rating of IO's Vin is 4.0V (page 56).In our application, operating voltage is 3.3V (Vdd=Vdda=3.3V), but the input voltage of PA0 ...
Posted on May 11, 2018 at 13:28Hi all, I'm using a STM32F215 MCU with a supercapacitor (like XH414HG-IV01E;SEIKO) connected to Vbat through a 0 Ohm resistor in order to backup RTC registers. I attach an image:Well. If I measure the voltage in VBAT p...
Posted on May 10, 2018 at 19:06Hello, I have a board with stm32f446rc processor and I don't get to connect bootloader with stm32 flashloader.Following below this function used to access the bootloader on chip. I am using USART1 (PA9,PA10) to connec...
Posted on May 09, 2018 at 08:37 Hello! I need to capture signals on inputs with constant frequency for further investigation. I use the following scheme: set timer frequency needed with update DMA request and capture size for DMA, then get data fro...
Posted on May 06, 2018 at 14:15On page 177 the definition of bits 4:0 and 12:8 of RCC_DCKCFGR appear to be incorrect.Should these be PLLI2SDIVQ and PLLSAIDIVQ respectively?
Posted on May 11, 2018 at 11:16Hi, I'm working with the RTC (LSE source) and I'm getting a bad format value, not a wrong value.I call HAL_RTC_GetTime(&hrtc, &sTime, RTC_FORMAT_BIN); and HAL_RTC_GetDate(&hrtc, &sDate, RTC_FORMAT_BIN); to get the actu...
Posted on May 07, 2018 at 15:37Hi All,Am trying to fix the RAM addresses for new global variables in .data segment. For this, I have divided RAM into sections and by using attribute Am fixing address for newly created global variable. It was looks f...
Posted on May 11, 2018 at 12:55Hello , Which STM32f7 discovery board has on board CAN transceiver ??I checked both these they lack this feature . http://www.st.com/en/evaluation-tools/32f746gdiscovery.html http://www.st.com/en/evaluation-tools/32f76...
Posted on May 08, 2018 at 19:54HI.I recently bought myself a board with a STM32f411 nucleo. And there was a problem in the fact that CUBEMX hovered and did not close it. What should I do? Thank you in advance!
Posted on May 10, 2018 at 11:12Hello,I have a small big problem. I configured my stm32 (F429) in CubeMx, everything works after sending positive data from the computer to STM32, but sending 0 resets the remaining bytes.E.g:I send: 1 2 3 4 5 0 7 8I r...
