Posted on January 16, 2015 at 13:48Hello, I have implemented SD Card with FatFS using firstly STCubeMX driver in a polling mode, secondly by adaptation of the \STM324xG_EVAL\Applications\FatFs\FatFs_uSD example in DMA/Intr mode. I am writing a line...
Posted on October 22, 2014 at 09:37How will itsupportSTM32F1inCubeMX?It isplanned toadd Clock configuration tools or Power Consuption Calculator?It isplanned toadd Firmware Package for Family STM32F1?If sowhen?If notwhy?
Posted on January 27, 2015 at 02:44Hello, I am testing an application on a Discovery STM32F4 board (MMB997C) I need a counter for very low frequency generation: 5Hz to 100Hz, so it looks like Timer 2 is the only one that will work OK to do the job a...

Posted on January 24, 2015 at 23:09For security reason, we would like to remote flash STM32F429, just like GPS online update, there is a way to do that? Thanks
Posted on January 26, 2015 at 03:47On the Discovery user Guide: DM00039084_STM32F4_Discovery_User_Guide On Page 39, there is a power switch: STMPS2141STR that has +5V connected to the input side. The data sheet for this does not indicate and voltag...
Posted on January 23, 2015 at 02:11 Hello, I am new to this forum and have migrated from Freescale to STM32 based projects. I am implementing a switched mode power supply (SMPS) on the STM32F4Discovery board. I have successfully configure...
Posted on January 16, 2015 at 13:27Hello, I have double checked all connections of SD card socket to uC on our board. We also have pull-up resistors there. Required setting of 4-bit access can be seen in the SDIO_CLKCR.WIDBUS register during debuggi...
Posted on January 26, 2015 at 16:13Hello,We have purchased HM301 evaluation board. However, we could not achieve to inject current for impedance measurement. It seems that all the software configurations are correct. What may the problem be? If I am...
Posted on July 21, 2014 at 15:54 Hello, I just ran into a trap with STM32F0xx_StdPeriph_Lib_V1.3.1 and have a suggestion for a fix. In function ADC_ChannelConfig() of file stm32f0xx_adc.c, the line 724 ADCx->CHSELR |= ...
