I am trying to read VBAT value through channel ADC1_IN18.VBAT should be between 2.3 and 3.3V.VREF+ pin is connected to VDDA=1.8V.Values measured using ADC are linearly related to the real VBAT value, but I have not been able to get the exact value.Fo...
Hello to the community!I've run into a strange problem on my STM32F7:I init, mount and open a file directly after the uC initif I read this file often (from my main() while(1)), I never have read problems (it can works for hours)if I don't read the f...
Hi all, I’m trying to test the can bus function with the STM32F042, I’ve studied all the Datasheet but I’m trying to find the best solution for an efficient store for incoming messages..My question is if I don’t know the right amount of incoming ID ...
Looking at the datasheet of the STM32L452xx family, it's noted that SRAM size is 160K.The memory mapping on page 86 notes the address range from 0x2000'0000-0x2028'0000.But 160K is 0x2'8000 and not 0x28'0000, which would make the range from 0x2000'00...
Over the past month, I've been trying to figure out if the DAC in the STM32F3 actually has a silicon bug. I observe a sawtooth with an approx 1 minute period in the DAC output (as measured by the ADC on the same chip). The first large "tooth" is alwa...
Hi All,I'v been working on a project wherein I use some portion of the flash to store certain data. Initially, after the manufacturing and assembly procedure, I don't usually get any issues at all, but after several months, the board starting to give...
Page 118, Table 38 has "1.78" in Peripheral column instead of TIM1.Page 115, fourth bullet says "... is given in Table 39. The power...". The table number should be 38.
Hi all, I'm using nucleo STM32 L4R5ZI .Using systick 120Mhz as clockand set timer 2 , channel 1 as TIM_TS_TI1FP1 (Trigger and rising edge)Then, using int count = __HAL_TIM_GetCounter(&htim2); to sample the count for every 1ms. Input 40KHz . By right...
I am French.There is now more than one week that I try, see youtube and some comments on forum. I need your experience for solving the initialisation of a "simple" PWM.Thanks in advance.Joëlhere under my code. in the main I have launch : PWM1_CH3N_se...
