Posted on September 24, 2017 at 23:23I want to write and read file using FATFS and USB DÄ°SK Host Only middlewares on stm32f411ve but the processor jumps to hard fault when it makes 'f_open(&MyFile,'example.txt',FA_CREATE_ALWAYS|FA_WRITE)!=FR_OK' c...
Posted on September 22, 2017 at 10:14Hi everybody! I'm using the input capture digital filter function of TIM15 on STM32F070CB. I need to filter out pulses shorter than 1.5ms and I want to keep FCLK at 48MHz.Problem is, in this case, I can't have a ...
Posted on September 25, 2017 at 03:20Hi.I'm looking for example of Software Interrupt in STM32F10x_StdPeriph_Examples, STM32F4xx_DSP_StdPeriph_Lib_V1.8.0Can I find that in Examples?
Posted on September 25, 2017 at 00:19Hello friendsI defined a variable uint16_t x;in my code I will compare x >= 500 Most of the time works fineBut sometimes variable is Overflow in 256 i see in debug variable is 0 after 255+1i using IAR , STM32F103...
Posted on September 24, 2017 at 08:01I'm about to start implementing driving a single GPIO pin with DMA timer-driven bit-banging and I have a bunch of questions. I'm throwing them out here first in case people know the answers to some (or all) of th...
Posted on September 23, 2017 at 16:27When is the ISPR register used?ISPR [0] | = 0x00000001 << 6; // (EXTI0 Position)Does this code convert the EXTI0 interrupt into the pending state so that the EXTI0 interrupt should not be executed?But the interru...
Posted on September 22, 2017 at 23:14hi i need start timer with external pulse at falling edge at one pin and i need stop timer with external pulse at falling edge at one pin can convert two 16 bit timer to one 32 bit timer ?on stm32f103c8t6 my time...
Posted on August 30, 2016 at 11:56Hi,I'm trying to figure out, how to use the CubeMX generated project for touch sense aplication. I'm able to detect the change on the 3 touch buttons, but i can't figure out, how to detect on which touch button did ...
Posted on September 26, 2016 at 16:23I need to simply capture an input level and then output the same logic level as soon as possible on another pin.This can be simply done with EXTI, but I was wondering if there is a passive peripheral based soluti...
Posted on September 19, 2017 at 23:41I have a custom board using an STM32L452. I'm doing some testing of the ADC and am finding pretty high levels of noise.I have a rail-to-rail op amp driving the ADC pin with a 300 ohm resistor from the amp to the ...
