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
Posted on March 26, 2014 at 11:26In the user manual: AN2606 - STM32 microcontroller system memory boot mode it describes that when using a 14.7456MHz clock crystal the bootloader configures the PLL to run at 48MHz. How is this achieved? What setting...
Posted on March 28, 2014 at 11:46Hello all,I am trying to connect a sensor to the stm32f4 discovery board. what i want to do, i want to be able to write to the sensor and read from the sensor the data. would you please guide me to any web resources...
Posted on March 18, 2014 at 16:34I've the problem that STM Studio is not able to import arrays (fixed size) of variables. That is, they are not in the list based on the imported elf file. Array of bytes are not a problem but arrays of all other typ...
