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 25, 2015 at 09:45when use i2c and remap pin , __HAL_AFIO_REMAP_I2C1_ENABLE(); function must be run before __HAL_AFIO_REMAP_I2C1_ENABLE(); /**I2C1 GPIO Configuration PB8 ------> I2C1_SCL PB9 ------> I2C1_SDA ...
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 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 ...
