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 ...
Posted on October 26, 2015 at 16:29 I'm using STM32F303 Discovery board. I try to evaluate how much code can be performed intimer's IRQHandler without causing desynchronization with PWM of the same timer. //interrupt code if (T...
Posted on October 28, 2015 at 17:30My fault. Post invalid. I looked at the schematics of the nucleo boards and mistook SD_VREF+ for VREF+. Sorry.Hi.In STM32F334R8 PB12 is connected to VREF+ for the ADCs.I have made a HW design using PB12 for other p...
Posted on August 26, 2015 at 16:26I am trying to use CubeMX to set up the IRTIM feature on pin PB9 on an STM32F051. The feature is complicated, as it used TIM16 and TIM17 as well. After configuring PB9, TIM16 and TIM17 in Cube as I would expect, PB9...
Posted on October 23, 2015 at 09:46Good morning, i've already working with a STM32F030R8T6 MCU but i need more flash memory.Is STM32F091RC pin to pin compatible with no code changes?There is a MCU similar to STM32F030R8T6 but with more than 64K Flas...
