Hello,I am working on a STM32F723E-Disco,I am learning the use of timers and their functionalities.In particular, I try to use the output compare.What I'm trying to do is to use the output compare to turn on a LED when the output compare is triggered...
Set the APB2 timer to 180MHz to generate a 25MHz clock signal in output compare mode.And it tries to increase the decoder signal by 1 by counting every 513 rising edges.However, the decoder input signal is toggled on more than 513 signals.By changing...
The problem arises because by selecting both HCLK and HCLK/8 the SysTick is always initialized like this:SysTick->CTRL = SysTick_CTRL_CLKSOURCE_Msk | SysTick_CTRL_ENABLE_Msk;thus selecting HCLK as clock source in both cases.Maybe the correct code sh...
I'm working on a batch of prototypes using the STM32L031 series, but can't seem to wake up the device using the WKUP3 pin. Waking it up through WKUP1 goes without problems, but I also need WKUP3.In my stumble I've come across a few possible hints:In ...
Hi everyone,I'd like to be able to locate some functions in ITCM RAM instead of FLASH using section attributes. I have a Nucleo-H743ZI. I already have it semi-working in that this code works as expected and runs from ITCM_RAM (checked with gdb):stati...
Generally, a basic circuit design to generate a 4 to 20 milliamp current loop would use an op amp, FET and handful of resistors in addition to an input voltage or current which, in this case, would be the DAC. (please see attached) Can the interna...
Hello,I am using SPI1 on STM32H743ZI MCU.When I use SPI Transmit Function it works well.But when I use :HAL_SPI_Receive(&hspi1, ads_buf, READBACK_LENGTH,500);ads_buf is still full of 0, it does not get filledI checked with logic analyser and it is wo...
I wants to get ping another device such as PC using lwip. I find some file in :https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Middlewares/ST/STM32_Network_Library/servicesbut the problem is that i can't use these functions. How can i u...
hi, i have to read and write to eeprom ic . i am able to write but i am not able to read from my ic . void write_eeprom_reg(uint16_t reg_addr, uint8_t value){//uint8_t d[3];d[0]=(reg_addr>>8) & 0xFF;d[1]=(reg_addr) & 0xFF;d[2]=value; while(HAL_I2C_I...
Hi all, I have an application under test with MCU STM32F411 that working in impulsive high magnetic field generate by a big inductor. Below the specification:duration of impulse 400us;intensitiy of magnetic field is 2,5 Tesla peak;magnetic filed has ...
