Variable frequency pulse train for pulse transformer application
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...
CubeMx LwIP update for F1 series?
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...
STM32F7 USB host CubeMX does not detect USB pendrive if it is inserted before reset
Posted on July 05, 2017 at 18:30STM32F7 USB HS host, in FS speed, with external PHY, no VBUS control (always on). The stack fails to detect USB pendrive if it is inserted before reset. I found there is interrupt but seem like the driver does not in ...

SDMMC_OCR_ADDR_OUT_OF_RANGE Error on L4
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...
How to protect non-volatile data from mass erase?
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...
STMCubeMX 4.18.0 generates incorrect PLL timing
Posted on December 05, 2016 at 21:55I am using STMCubeMX 4.18.0 configured for STM32F446ZET. When I set Clock Configuration HCLK to 180 the following lines in main.c cause the processor to hang: RCC_OscInitStruct.PLL.PLLM = 4; RCC_OscInitStruct.PL...
