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 August 22, 2012 at 17:22Hi The objective is to create a variable frequency pulse train with as little CPU intervention as possible. This was quite straightforward with the TMS320 TI MCU. It had a feature called ''PWM chopper'' where it was...
Posted on June 21, 2017 at 11:14Hello,im working with the STM3210-C Eval board (F107VC microcontroller). I recognized that for F1 series there is in CubeMx (ver.4.21.0) only a LwIp version 1.4.1 available while for F4 series there is version 2.0.0 i...

Posted on July 05, 2017 at 12:11Hi,i'm working with little project on STM32F105, but libraries have never been corrected from STM and bugs are presents also on last version* @version V1.0.4* @date 29-April-2016.Now i have a little doubts about STM l...
Posted on June 12, 2017 at 16:04I noticed that fatfs when performing single readblock_dma operation occasionally ends up with error SDMMC_OCR_ADDR_OUT_OF_RANGE when issuing command:SDMMC_CmdReadSingleBlock(hsd->Instance, BlockAdd);Any advice on to w...
Posted on July 04, 2017 at 10:50Hello everyone,we need to protect certain calibration data we store in a STM32L051 microcontroller from being deleted by mass erase operations.The scenario is as follows:1- Our production stores some calibration bytes...
