Posted on October 29, 2015 at 09:00I'm having a big problem.I have an USART which uses a circular buffer with DMA to receive characters.The machine sometimes has to save some informations in internal EEPROM.After some time, from minutes to many hour...
Posted on October 28, 2015 at 08:49 I am using an STM32F4 discovery board and my intention is to set one of its GPIO pins at high impedance, which I have done as below: GPIO_InitStruct.Pin = GPIO_PIN_12; GPIO_InitStruct.Mode = GPIO_MODE_INPUT;...
Posted on October 29, 2015 at 08:47Hi,I am using STM32F051R8 eval board I am trying to read temperature sensor and internal voltage values but some times I am getting wrong ADC conversion valuesvoid MX_ADC_Init(void){ ADC_ChannelConfTypeDef sConfig...
Posted on October 26, 2015 at 09:51 I checked the code, it works when picture is in memory. But I can't make it work with MicroCD. I rewrote the code for work with FatFs, but STM32 freezes on f_lseek() function. There is my code, I purpo...
Posted on October 20, 2015 at 11:34 Hello, I updated ST library and got huge delay during I2C transfers when I have some errors. previously I manage timeouts in my firmware now some timeout hardcoded for example: #define I2C_TIMEO...
Posted on October 25, 2015 at 18:59is there is any example of STemWin using FreeRTOS? I am using discovery kit STM32F429 I have my main function has only GUI_Init(); I keep getting this error region `RAM' overflowed by 1919320 bytes
Posted on October 28, 2015 at 13:28 Hello, I have following problem with copying hex data. for (i = 0; i < 6; i++) { printf ( ''%02x'' , packet[i]); // copy packet to FIFO } Printf copy data from packet[] to FIFO...
Posted on October 28, 2015 at 14:20Hi,I am working with a STM32 data logger with a pulse counter, SPI accelerometer and ADC connected. I am puzzled: how can I design a common 4/8Kb buffer for time-synchronous sensor values for later SDIO SDcard stor...
Posted on October 28, 2015 at 19:36Hi everyone,MCU: STM32F302I have to configure 2 differents analog comparators (Comparator 1 and comparator 2). Each comparator are linked internally to TIM1_OCRefClear. Is that a problem to control the same signal ...
Posted on April 21, 2015 at 15:18Hi everyone.In a new development with STM32F407I i have some problems with backup domain especially with internally switch Vdd/Vbat to backup domain.I use a CR3032 backup battery ( 3V lithium ) connected to Vbat pin ...
