I want to run the NUCLEO-F042K6 on external 3V3 supply. I understand that in this case ST-LINK remains down, and I cannot use its crystal for clocking. I want to use a crystal to clock the MCU.Looking at the schematic[1], I wonder if I can use the sa...
Hello everyone,I have to freeze watchdog during debug mode because it geneates problems (the same old story).I tried to use __HAL_DBGMCU_FREEZE_IWDG(); before main loop, but this is not the right solution.Have some tips?Best regardsPS: I use an STM32...
My first goal is to reach the sampling time of 2us. I am using timer2 as interrupt to read an analog signal from AN0 and to measure the adc sampling time, I am toggling a led every time I read a value in the callback interrupt and checking the toggle...
I'm using a STM32L486RG and i try to chain TIM5 to TIM3 and it fail (TIM3->CNT doesn't increment). The other chaining combinations work correctly. Here is my test code:#include <assert.h> #include <stdbool.h> #include "stm32l4xx.h" #define TIM_MA...
Posted on April 29, 2017 at 07:40Hi , all:I use STM32CubeMx to generate MDK V5 project for my stm32f746g-discovery board.I found I can't use the SD with FATFS after add STemwin Lib to my project , but it works fine only if i just use SD and LTDC ...
STM32F746GDiscovery, CubeMX. Selecting RCC-> LSE causes the Clock Configuration error. I want to use this clock.
Hello,for most reference manuals, e.g. RM0390 Rev 4 for the STM32F446 the timer block diagrams (e.g.Fig 110 for RM0390) miss the source for the TRC signal. Reference manuals for recent devices (rm0433, rm0438) mark the source. Future revisions of STM...
From STM32F373xx datasheet, SAR ADC characteristics, page 99/137, for Vdda = 3V, i can see thatED - Differential linearity error is max +/-1 LSBEL - Integral linearity error is max +/-1.5 LSBBut in SDADC characteristics, page 111/137, the difference ...
Hello,i found a strange behavior having 2 timers running.My initial intention was having 4 input captures on the 32F746GDISCOVERY spread over two timers (no timer with 4 pins connected to the Arduino Header) one running as master and triggering the s...
