Why USART transmission depends on function calls order?
Posted on July 23, 2014 at 17:22 Hello, please help me to solve next problem. I have application, which consists of three main modules: io_init(), lcd_init() and usart_init() �? io_init() configures button inputs and some outputs used for relays ...
Using structure causes Hardfault exception
Posted on July 23, 2014 at 23:49Hi everybody,I'm trying migrate a program from 28335 to stm32f407. I was using a structure to store some data, and passing the pointer to this structure to a function. Now I find that if I define the structure variabl...

Use DAC of STM32F103RET6 to create meaningful sound.
Posted on July 14, 2014 at 12:47Hello Everyone , I am using STM32F103RETG to create a sound.I am also using elua and minicom to execute the program onto the uc. My plan is to - *first use the DAC wave generator to create a simple noise. I will be us...
Set GPIOs to high impedance
Posted on June 27, 2014 at 10:11Hopefully this is an easy question: To set up a GPIO to high impedance mode, I have to configure it as input? If I want something connected to ground at this pin, I can set it to an output with low level? What I actua...
Configure the timers count at 32-bit
Posted on July 18, 2014 at 08:39Hi, I'm using the device STM32F030C8T6 that has all the timers count at 16-bit. I need using the timer count at 32-bit. In the data sheet in the page 67 reads ''Maximum possible count with 32-bit counter''. How can I...
STM32Cube SDHC capacity bug (solved)
Posted on May 11, 2014 at 17:21Hello, in stm32f4xx_hal_sd.c line 1554 :pCardInfo->CardCapacity = ((pCardInfo->SD_csd.DeviceSize + 1)) * 512 * 1024;should be :pCardInfo->CardCapacity = (uint64_t) ((pCardInfo->SD_csd.DeviceSize + 1)) * 512 * 1024;or...
USB MSC ''STORAGE_GetCapacity_xx()'' bug
Posted on July 23, 2014 at 05:09Hi allI am sure this has been discussed (although I cannot find any reference to it):The SDIO capacity bug also extends to the ''STORAGE_GetCapacity_xx()'' functions where it enters with a pointer to a uint32_t value ...
ADC: first injected channel creates voltage peak
Posted on July 22, 2014 at 10:53Hello!I have a problem with the ADC on my STMF4Discovery Board.I am reading two analog voltages with ADC1 in triggered injection mode.The voltage on the pin with injection rank 1 always has a peak at the injection eve...
