Posted on November 14, 2016 at 22:07In a new project there are several identical STM32F031 devices in a role of a slave mcu, driving LEDs and reading in various input signals. As their functionality is very similar, it is tempting to have only one s...
Posted on February 23, 2017 at 00:04Device: STM32F437I am using ADC3 channels 5 (rank 1) and 8 (rank 2) in interleaved mode, the input for channel 5 is 0 volts and the input for channel 8 is near upper limit. Trapping after the first interrupt the 3...
Posted on February 24, 2017 at 14:25How to jump to another application in Flash memory on stm32f4-discovery board? Can anyone give complete ibstruction step by step? I have already written bin file to flash. Now I want only to run it. I looked throu...
Posted on February 24, 2017 at 13:28Hello,as L1/F2/F7, Stm32F4 has no explicit Gpio Bit Reset register. To reset a Gpio bit , the bit in the uppper halfword of BSRR has to be set.In some recent Cube update, definition like#define GPIO_BRR_BR0_Pos (0...

Posted on February 23, 2017 at 11:48Hi,In the current datasheet of STM32F103 (DocID13587 Rev 17) it is written:5.3.14 NRST pin characteristics The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU (see ...
Posted on February 09, 2017 at 13:38Hey,I'm using the Input Capture of TIM8 to measure the period of a signal. The Timer runs at 16MHz and the MCU (STM32F405) at 144MHz. I'm also using the ICFilter at the moment. The value is set at 0x02. My questio...
Posted on February 23, 2017 at 19:53Hello,I have need to bring up SPI1 (PA4,PC5,PC6,PC7) on an STM32F103 in master mode using the least code possible. I have a function that (is supposed to) initialize the SPI. I am using the bit-band region to mani...
Posted on February 23, 2017 at 04:59I have X-NUCLEO-IHM02A1 expansion board.And downloaded the its firmware file of X-CUBE-SPN2.The file can not be unzipped.Please check the zip file and upload latest one as soon as possible.thanks
Posted on February 22, 2017 at 22:05Hi,I'm working on a stm32F101CBT6.The board has a 16 MHz HSE (connected to PD0.PD1) and a 32.768 KHz LSE (connected to PC14/PC15).The board will use SPI1, SPI2, USART1, USART2, I2C1 and a few GPIOs.I've worked wit...
