Posted on March 26, 2015 at 15:48Dear All, I am new to an embedded world in general and to the STM32F4xx controllers in particular. In order to learn the trade, I got the STM32429I-Discovery board and along with the hardware, I have installed: ...
Posted on February 10, 2015 at 14:30Currently I'm developing a battery powered application with lcd and stm32f103 (1MB).Because a full screen update is ugly-slow on 32 MHz I'm looking for ways speed up to 72 MHz. But since this doubles the current c...
Posted on September 20, 2012 at 03:51I have EXTI example running on my stm32f4 board but I am having trouble changing the PIN which causes the interrupt. Here is the initialization method:void EXTILine0_Config(void) { GPIO_InitTypeDef GPIO...
Posted on March 26, 2015 at 15:01I was wondering what the negative input can be on an ADC pin. We have an analog signal that can be very rare -38mV for a short moment. In the datasheet page 60 of the F411 i can only find Absolute maximum ratings: In...
Posted on March 26, 2015 at 14:59Hi,I am trying to program stm32l051 MCU using IAR workbench and stlink V2 debugger.I am facing an issue while trying to program it when MCU is in stop mode. In normal mode it works fine.It is also observed that durin...
Posted on March 26, 2015 at 14:47I have an STM32F427 / LQFP144 design and am interested in migrating to the STM32F446. What changes do I need to consider (hardware and software)? Primary Peripherals: SDCARD (SDIO), Codec, SDRAM(16M x 16bit), USB (as...
