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 July 26, 2016 at 19:52Hi, I am trying use sd card on stm32l476 with HAL driver. I can initialize and read any block and it work fine. Write block not work and always got SD_DATA_CRC_FAIL error. I have same board with stm32l151 it work fine...
Posted on July 27, 2016 at 15:29Hi all,I would like to know if the MCU is broken/burned without giving power to the MCU. The chip is STM32F407VGT6 (the one used in STM32F4 Discovery Board).Thanks in advance!Cheers,Ogulcan #stm32 #debug #power
Posted on July 27, 2016 at 15:00Hello everyone.I am writing an application for a STM32L4 that is 99% of the time in stop mode 2 to save power, and some time it wake up (with an exti) based on an externall event. When it wakes up it takes a measureme...
Posted on July 27, 2016 at 11:13Hi: I used STM32F401RE nuclo board test RDP found that if i changed RDP level0 to level1 ,the code can't run. At the same time,i used the st-link utility to test it,found same question,i download the hex(LED demo) the...
Posted on August 03, 2012 at 06:16Hi, guys Recently, i'm working on a board based on STM32F417ZG chip. And i connect the FSMC bank1 NE1 to M29W128GH NOR flash chip, the address is 0x6000 0000. My tool chain is ARM MDK + J-link, and i make the flash ...
Posted on July 25, 2016 at 23:29Hi, I am trying to stream a 1024 sample buffer to PWM in timer1 channel1 using circular DMA. But how will I control the speed of streaming from RAM to PWM at 44KHz? I couldn't find any option like triggering option...
Posted on July 27, 2016 at 05:06The processor is an STM32F373VCT6. I am software triggering SDADC1 every second using this call each time: HAL_SDADC_InjectedStart_DMA( &hsdadc1, (uint32_t *)SDADC1_Data, SDADC1_Data_Size ); The DMA buffer size has 20...
Posted on July 26, 2016 at 17:28I have been using a busy for loop to create my delays, but now I need precision. I want a function that will wait for n microseconds. How should I go about doing this? The Systick timer is not accurate enough (already...
Posted on July 26, 2016 at 23:07I am trying to configure an external audio codec to work with the STM32F4 discovery board. I have got the onboard codec working via the spi driver (stm32f4xx_spi.c) and was wondering how I would have to configure thin...
Posted on October 17, 2011 at 21:30can i but 9 bits in the SPI Tx buffer configured in 8bit mode and have it still clock out all 9 bits???
