Stm32F4 internal temperature reading with stm32F4 peripheral library V1.4.4
Posted on October 03, 2016 at 11:36Hi,I want to read the internal temperature of STM32F429II. I am using stm32F4 peripheral library V1.4.4. Below is my code,// Initstatic HAL_StatusTypeDef ADCx_Init(void){ hAdc.Instance = ADC1; if (HAL_ADC_DeInit(...
STM32F411 SPI RXNE bit is automatically clear
I'm very first to embedded programming, i have written a application using SPI protocol to communicate with 2 STM32F411 broads. And I got trouble in slave code, when the data from the master are sent to slave, then slave RXNE bit is set and go to SPI...
Resolved! HAL_NVIC_SystemReset() gets stuck, same with IWDG.
Hi. When I call HAL_NVIC_SystemReset(); or NVIC_SystemReset(); the system just freezes up instead of restarting. I figured forget about it and moved on to try out the watchdog, well the same thing happens. Watchdog is enabled and working fine, then I...
STM32CubeMX SD CARD Code Bug
Posted on January 31, 2018 at 12:48Hello,A while I used stm32cubemx for generating a code for SD card connection to my stm32f4 with SDIO and FATFS middleware and it worked fine but after the recent cube update the similar code does not works for sd ...
STemWin's GUI_Init() hangs in call to DMA2D_FillBuffer()
Posted on June 01, 2016 at 22:41This appears to be a different GUI_Init() hang problem than those mentioned elsewhere on the Forum. My app enables the CRC module via the following Cube-generate call MX_CRC_Init(). This code is running on the 469i_Di...
How to use eval board under windows 10
Hello,I used a STM32F103C8 eval board under windows 7 and everything worked fine. But I have to change to window 10 and I tried now for several hours to get a functional connection by reading many discussion of about stm32 vitual com port, etc.Can yo...
STM32439I-EVAL: Using a memory daughterboard without interference from the SDRAM
Posted on July 07, 2016 at 23:47HiI need to use the CN11 and CN12 connectors to use the FMC Bank 1 interface with an external memory board. Looking at the manual and schematic, it doesn't look like there's a way to disable the chip select on the eva...
stop NRST pin being driven by flash programming algorithms.
It looks like I made a fatal mistake by connecting the NRST pin to the PA0 pin on an STM32F778AIY. This is a part with no internal voltage regulator for the core so the PA0 pin acts like a power on reset. This hasn't caused problems with power cyclin...
I2C base clock 8 / 16 / 48 / 100MHz? What to use best?
In the STM32H7 RM (July 2018) chapter 46.4.9 ("I2C_TIMINGR .. examples") you give example settings for i2c_ker_ck frequencies of 8 / 16 / 48MHz (thank you, very helpful - just a bit awkward that you use there the term "fI2CCLK" for the frequency ... ...
