I want to use an SR latch to detect the alarm pulse on the tamper pin ( STM32F103C8T6), is this possible in Vbat mode? if it is, then what amplitude is this pulse (I am asking because it might be possible that the pulse wasn't high enough for the sr...
HI all,I have a custom board with stm32h743vit6 microController.I configurated SPI1 for comunicate with a SPI display (ili9488 managed by touchgfx with partial frame mode).My problem is that I can't reach high speed (more than 25mhz on SPI) else the ...
Posted on March 31, 2016 at 12:11Hello I'd just like to know why CubeMX strongly recommends to use other timers besides SysTick as source? I've always thought that the SysTick timer is basically intended for use with an embedded OS? Thanks
Which STM board has both input and output, digital and analog pins?Thanks in advance.
Hello, guys!My name is Luis and I bought the board STM32L562E-DK for testing purposes for a new project.I have been executing many examples based on freertos and I am very happy on how the STM32L562Q could be my solution in a future project.However, ...
Hi, I am having data transfer problem with Modbus only when I use a specific RS485 Converter .I am using STM32H750VB as my main IC for a fuel dispenser project. I am having a problem with my MODBUS based on the RS485 converter.i)If i am using...
Hi there,I have problems when I m using the FDCAN controller. I m using the NUcleo STM32h745ZI with a shield with a can controller on in CLASSICAL CAN mode (NO FDCAN).If a run an example in the HAL_Driver folder it works ( @1MHz Fdcan kern freq = 40M...
I'm using PB14, TIM15_CH1 for my PWM signal. Since it's TT_a I/O structure 3.6V tolerant.
Hello,I'm working on a nucleo-f401re board, with HAL library.I'm trying sampling a signal and measure its duration, to do it I'm triyng to use the TIM2 of my board to detect rising and falling edges of the start signal, and this works fine.I would al...
Does anyone know how you're supposed to get a clock speed of 480Mhz when the lowest PLLP1 divider is 2, and the max "wide" VCO freq (Input source / DIVM1 * DIVN1) is 836Mhz? Ie This seems to cap the max speed at 418Mhz. Of note, Cube doesn't complain...
