Posted on May 04, 2016 at 10:02Hi all. I am trying to reduce power consumption in my device by disabling the GPIOs ports clocks. I did it by writing '0' in the RCC_AHB1ENR register at the required locations. However, It did not work... Then, I did ...
Posted on April 29, 2016 at 23:43Hi,I've been utilising the x-nucleo-idw01m1 projects that come with the wifi shield on the STM32f401re nucleo board and they work great. I've decided to port one of the examples to use my 429zi nucleo project. I've g...
Posted on April 12, 2016 at 11:39Hi there, we are prototyping a product that involves an STM32F042. It was working great but ... two units got the STM32 blown up! It just gets really hot and nearly pulls the VDD down.Some details and ideas:- We didn...
Posted on April 20, 2016 at 09:38 Hi! I try to measure GPS PPS (pulse per second) duration by TIM2. Setting code: TIM_TimeBaseInitTypeDef TimeBaseInitStruct; TIM_ICInitTypeDef ICInitStruct; TimeBaseInitStruct.TIM_Prescaler = 0; TimeBaseIn...
Posted on May 04, 2016 at 10:58hello every onei want to design stm board which should has device firmware upgradebut in this case i have no access to boots pinsmy upgrade data will be send by 3g (GSM module) to board and 3g module just have serial ...
Posted on May 04, 2016 at 11:27Hi All,Sometime ago, I developed a bootloader for firmware update over the air (GSM/GPRS network) for STM32F0xx SOC; many thanks to ample information shared by the community members and ST's documentation. To make the ...
Posted on May 03, 2016 at 23:27We set ADC1 on the M0 micro-controller to listen to a GPIO pin. Under low power mode, the reading is shifted.The low power mode for ADC setup is as following: .Instance = ADC1, .Init.ClockPrescaler = ADC_CLOCKPRE...
Posted on May 02, 2016 at 19:45Hello!I would like to ask, if anyone knows, if there is a DSP instruction for Cortex-M4, which would calculate x*x + y*y. I saw that there are some quite complex instruction which are intended for similar calculations,...
Posted on April 16, 2016 at 16:40Hi all, I have trouble getting a LDC Display on the STM32F429 FMC to work in 8080 Mode. I use the same hardware connection like withe STMF4Discovery Expansion Board and the STM32F4DIS-LCD Modul.FMC_D0 (PD14) -> LC...
Posted on April 22, 2016 at 11:07Hello communityI am having troubles when doing DMA with USART on an STM32F030. Thanks in advance to anybody will help.Not sure if i did the homework correctly so I need someboody to check thisTMy application aims to ...
