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 26, 2015 at 19:30Hello, I've tried to run default RTC configuration at STM32L Discovery demo board using cubeMX but even if I tried to switch between clocks my code always get error with function:RTC_EnterInitMode() in ''Wait till ...
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 |= ...
Posted on January 21, 2015 at 14:09Hi all, i'm using STM32F407/F417 with 12MHz crystal, and i would like to save power as possible, because i need to run it on batteries, i need to have USB connected, i read in manual that i could underclock ......
Posted on September 08, 2014 at 23:47I am working on the STM32F302 Micro and I currently unable to receive data on the CAN bus, I have a break point set on the interrupt routine. I am able to transmit data. I am seeing the micro sends an acknowled...
Posted on January 21, 2015 at 19:27Hello there!I need to develop the device which has to sustain heavy mechanical shocks (a peak of 10 000g). I am going to use http://www.ti.com/product/MSP430F5438A-EPSTM32F405RG. What level of mechanical shock can ...
Posted on January 26, 2015 at 14:26Dear all,I face a strange behaviour of a timer. I appreciate any comments and suggestions.The timer is configured in one pulse mode and with slave mode 'trigger' from channel 1. With a rising edge the timer is trig...
