Posted on January 23, 2018 at 10:37I found a strange behavior of the STM32L NUCLEO cards. I installed a sensor network using Contiki and I implemented an RTC. If I try to set RTC_SYNCH_PREDIV to a value above 1023 (for example 2047, 4095, ... up to ...
Posted on January 23, 2018 at 14:43Should the NRST external reset (PINRST) be set on an STM32F407 after a power reset?I want to be able to count the number of each type of resets in my code. The problem that I have is that the NRST pin reset is alwa...
Posted on January 22, 2018 at 19:15Hello to all. I noticed that in the latest release of firmware for the STM32F7 (v1.9.0) the example application FatFs_USBDisk no longer works. During any fs_open command, an error is generated, and the app halts.Th...
Posted on January 23, 2018 at 13:24Hi,I am developping an application with a STM32F746ZG using the SPI interrupt to send data to a DAC. I am using the HAL_SPI_Transmit_IT() function to send this data in order to send a waveform. The fact is that I w...
Posted on January 23, 2018 at 12:57Hi,I am using I2C to send data between two STM32F4 MCUs with the same MCU working as a Master always. The master MCU controls a display and sends the slave a massage just when the user changes a parameter.I am usin...
Posted on January 19, 2018 at 15:52hello, I'm working with the stm32f4-discovery Board , in fact i have a problem using the DMA with an ADC 'injected channel'. I've configured the DMA to transfer the converted data from the injected data register 'J...
Posted on January 15, 2018 at 14:36I am new to STM32 controllers and I wanted to create a sample code for counter in TIM1. I am facing a problem that the update interrupt flag, which is supposed to go high when counter equals ARR register, is going ...
Posted on December 18, 2017 at 07:18when used the 103 series MCU, the SWD port will been disabled in follow step.1) enable the SWD interface. 2) enable tim3 CH1 PWM function and remapping the output pin to PB4. 3) when the tim3 init code run to __H...
Posted on January 17, 2018 at 11:38Hi,I was doing IAP&App in STM32F030rc. When I finish IAP and APP, and run from IAP to jump to APP, it can not be realized. I have try many ways, but useless. Please help me, I have waste a lot of time for this func...
Posted on January 23, 2018 at 02:24I want to add crc function in STM32F030RC, so I add HAL_CRC_Init, and related functions. But there is always 'no definition for 'HAL_CRC_Init'' error when link. I have include 'stm32f0xx_hal.h','stm32f0xx_hal_crc.h...
