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 June 16, 2017 at 00:32STM32L476I can't seem to glean the needed settings from the RM0351 rev 5 to get this to work like I thought it would.It seems to somewhat work but I can't get any counting to happen with transitions on input 1 (PC0). ...
Posted on June 28, 2017 at 18:41Hi everybody,I'm wondering why the HAL library does not allow to program an auto wakeup for a STM32F042.It is not allowed via CubeMX GUI neither.I've looked into hal files :every function used to init/use the auto wak...
Posted on June 29, 2017 at 14:30I try to make some noise using a small 8 OHm @ 1 kHz Buzzer connected to the STM32F446 DAC_OUT1. Seams the PA4 pin got damaged due to high or reverse voltage induced by the buzzer. I used th push/pull GPIO config. Is ...
Posted on June 16, 2017 at 23:56From the STM32F412G-DISCO demouint32_t HAL_GetTick(void){ return (DWT->CYCCNT / (HAL_RCC_GetHCLKFreq() / 1000)) ;}How exactly does this wrap properly within the 32-bit number space? Answer: IT DOESN'T
Posted on May 23, 2017 at 10:55Hello,I am trying to reduce the HCLK frequency down to 8MHz or less on an STM32F405 MCU.Using STM32CubeMX, when I configure an HCLK clock lower than 30MHz with the clock configuration tool, the box with the HCLK freque...
Posted on June 29, 2017 at 16:01Configured USART1 of mcu to 500 kbit/sec using STM32CubeMX Version 4.21.0.Code created by Cube seems to be correct.Measurement shows that bitrate is 250 kbit ( a 10 bit character needs 40 µsec).See Attachements.USART...
Posted on June 29, 2017 at 08:03Hi,I prepared several project files for a few DISCOVERY boards (I shared examples for STMF429, STM32F746, STM32F412, etc), but this time it seems to take more time than I expected. Maybe someone from you guys already ...
Posted on June 22, 2017 at 20:13Any reason not to drive 6 L6472 daisy chained devices directly from the STM32F303 SPI bus? Running at ~1MHz.
Posted on June 27, 2017 at 12:54I recently bought a X-NUCLEO-IDB04A1 and wanted to use it with Arduino. How do I go about it ? Please help me out.My aim is to collect the sensor data from http://www.st.com/en/ecosystems/x-nucleo-iks01a1.html and sen...
Posted on June 22, 2017 at 14:35Hello,the Ethernut (http://www.ethernut.de) STM32 Ethernet driver from svn head (/sourceforge.net/projects/ethernut/files/) works reliable for F107/F2/F4 and F74. However for F767 Revision A chip (no Rev Z chips avail...
