Hi, i'm trying to configure the SDMMC device to be driven by the HSI48 clock, here is my configuration at the moment. Previously, i had configured the SDMMC with the PLLSAI clock and it worked at certain frequencies (38KHz.etc) but i've read in the s...
I am doing one project with STM32H743ZI.I am using the external interrupt and copy the signal and set the output as input.But is shows about 700us delay.I do not know the reason why its gives such a big delay.
I am using an STM32H753. I2C1 (for an EEPROM) and I2C3 (for a touchscreen) are set up in the same way. Interrupt priority 10 for both, 400kHz. I can transfer data via I2C3 using interrupts, but when I try the same with I2C1, the interrupt handler is ...
Works: printf("hello world\n");Does not work: printf("goodbye world !");I have tried to find the answer in gcc´without success.
I am working on a project where I am using two boards to communicate via SPI. The master board (TMS320F28377S) is sending data successfully via SPINow, my receiver board is running on a STM32F439 processor, I'm relatively new to this micro. I configu...
int Pulse(void) { TIM_TimeBaseInitTypeDef TimeStruct; RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2,ENABLE); TIM_SelectInputTrigger(TIM2,TIM_TS_ITR3);// TIM_SelectSlaveMode(TIM2,TIM_SlaveM...
In Keil.STM32L4xx_DFP.2.5.0.pack, which can be downloaded at https://www.keil.com/dd2/pack, the memory information for stm32l452 says that the ram size is 0x00020000 = 128kB, but it actually is 0x00028000 = 160kB (SRAM1 + SRAM2).Using this file for m...
How should a UART interface be designed so that a robust communication possible can be established between two MCUs. The following table is shown in a data sheet from Texas Instruments. You can see the error rate depending on the baud rate. According...
Hello All, I want to find the Vref Voltage on which my ADC is operating. For this I am trying to find the VDDA. To get the VDDA I need to find the VREFINT_CAL value of my Microcontroller. I am unable to find the memory address for the same in both da...
I make a simple file system with 256 files. In the header I want to put data about the file system.The data is presented as an array of structures:typedef struct { const char name[20]; const char textExtension[4]; const uint32_t size; ...
