STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
Posted on May 03, 2018 at 18:03Hello,I'm working on a board based on STM32F427 MCU. The board is implemented as a USB Host.I'm trying to get SiLabs' CP2102N working as a USB device. I understand I'll need to change the driver to make it work. Have a...
Posted on March 26, 2018 at 07:10I am using STPM32 with STM32F4 microcontroller series. We are using UART communication. When we trying to reset the whole framework the controller only receives 0 values for 48th register. When we are trying to set t...
Posted on March 29, 2018 at 13:55Hi, today I have observed and solved a problem when I started to develop my simple program for NUCLEO-F746ZG. A problem was following: EXTI15_10_IRQHandler interrupt fired always - regardless of my changes in progra...
