Posted on May 02, 2018 at 03:43The TIM2 timer on an STM32F0 seems to not be resetting to 0 once the counter reaches the ARR value on occasion. I am periodically changing the ARR value, but the values are all in a small range. After a random amount o...
Posted on May 03, 2018 at 10:39I am quite new to STM32 and never worked with a Nucleo before. I am trying to control two motors (from a hoverboard) with a Nucleo F446RE. I found a perfect example with libraries and example code on GitHub, but someh...
Posted on May 03, 2018 at 14:00I'm working with stm32vldiscovery and I'm going to use max232 for USART. I'm using usart1 (pA9 and pA10 as TX and RX).The question is witch is the best way to make it wortk correctly and safetly specially with the RX p...
Posted on April 11, 2017 at 22:31I use the following code to initialize the GPIO for EXTI interrupt handling.I want GPIO F14 to trigger on the falling edge and most of the time it works properly.However, every 1000 or so interrupts, the EXTI Interru...
Posted on April 30, 2018 at 06:27STM32F769I DISCO board has 2 input options (mics and line in) and 2 output options (headphones and speaker). According to the examples in the CUBE package, we have the option to use both outputs simultaneously. Is it...
Posted on May 03, 2018 at 23:36Hello,I am making a custom board based on STM32F3 discovery board. My custom board is an exact copy of the discovery board with additional sensor components. I can easily program STM32F3 board as st-link is already bui...
Posted on May 03, 2018 at 13:37I have recently acquired an STM32F769I-Discovery board and am trying to drive a strip of 60 addressable leds (ws2813b).Because I don't want to use the processor to bit-bang data to the leds (I want the processor free t...
Posted on May 03, 2018 at 19:43I'm trying to program STM32L4-discovery board using the registers of ST32L4 only. I wanted to modify flash latency and see if the register value really changes by using gdb. However, it turned out that the following si...
Posted on April 03, 2018 at 20:44I've configured a number of pins on the 767 as EXTI but there is no option in NVIC to enable the interrupts and no code generated. The pins are correctly identified in the GPIO configuration tab.Moreover, the exampl...
Posted on April 25, 2018 at 16:40Hi,I�m working on a project with the STM32L4 on a custom board. We want to access a eMMC to store acquired data. First, we used the HAL_sd.c library, but since it�s not compatible with eMMC, we now want to use the lo...
