Posted on March 29, 2014 at 02:21 Hi, I'm entering in STOP mode with the command: PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI); But, when it resume from STOP, I cannot write to EEPROM anymore. I'm unlock...
Posted on October 29, 2013 at 15:56Hello everybody, I'm looking for a working example using OUT Endpoint on STM32F4 Discovery board. I have no success with it. I modified Demo sample for an OUT Endpoint and Custom usage, and try to send one byte rep...
Posted on March 29, 2014 at 17:53 Hello stmGuys. I'm having a problem configuring my DMA. I've tried everything I can imagine and it still doesn't work. I want the DMA to transfer data from a memory array to the GPIOD->ODR register. Here is my DMA...
Posted on March 30, 2014 at 08:39Hello,I want to use WFI, but I'm wondering how it works, what triggers the WFI to exit low power.I've defined systick for 1uSec (I'll use it later for some delays).I've defined timer2 for 100mSec.I need to do some ca...
Posted on March 28, 2014 at 21:35 Hello, For a project I am working on I would like to generate interrupts on both edges of the HSI clock, for synchronization purposes. The sysclk is based on the main PLL, sourced from HSE. ...
Posted on March 19, 2014 at 19:43Dear All,I would like to create a 1.5 MHz Sine Wave using TIMER + DAC + DMA.I have started from the DAC_SignalsGeneration example for Discovery board and then I have modified the TIM_TimeBaseStructure.TIM_Period fro...
Posted on March 29, 2014 at 15:32I have some IoT application, where power gets quite critical. Comparing the current/MHz of different suppliers, I found the best STM32 in the STM32L0 line at about 80uA/MHz. Atmel proposes a pico-line with 70uA/MHz (...
Posted on March 29, 2014 at 09:18I am using DMA to transfer ADC data to a uint16 variable @ 1MS/s Than the value is shifted with another DMA channel to SPI and sent to an external DAC. Unfortunately the external 14 bit ADC does not allow for left a...
Posted on March 29, 2014 at 00:40Is anyone aware of any documentation that contains an easily parseable system register specification for an STM32 MCU that one could use to generate code, documentation, etc... from? Something like the reference man...
Posted on March 28, 2014 at 16:42I want to generate sine wave (single cycle) and then change the frequency using DAC. basically Sweep the frequency... How would I do that.Thanks for your help in advance. #stm32f4
