Hello, i have the following setup code for i2c and DMA, where i use i2c1 to send some buffer data to a display. DMA_DeInit(DMA1_Channel6); DMA_InitStructure.DMA_BufferSize = DMA_I2C_BUFFER_SIZE;//BufferSize; DMA_InitStructure.DMA...
Hello,i am using on stm32f103 timer2 where channel1 & channel2 are used as input capture for reading a external rotary encoder.Since my design is quite tight ( using almost all pins available), i need to generate a PWM for an external LCD backlight ...
i want to generate 50 % duty cycle at freuency (100khz-200 KHz), but i am not getting 50% , i am getting 33-34% duty cycle.this duty cycle change when the frequency change.
HiI am working with a project were i am using two DAC channels and a SPI port set to receive mode and I want to use these in DMA mode. I am using the CubeMX to set this up and if I only setup the DAC and SPI in DMA mode, then it works as it should, w...
This is DMA error: SDMMC_ERROR_RX_OVERRUN meaning Receive FIFO overrun. This typically occurs after about 1 week of normal running. I have a test mode that simulates SD card usage to recreate 100 days of usage in 22 hours.If the SD card is kept on, t...
Hi there! I’m an electronic engineering major, and I currently enrolled in a graduation side-project activity in robotics and mechatronics. During this process, I’m supposed to work with STM32H743. By now, I need to read a single-ended voltage value ...
Hi, I want to use OTA in stm32h743, for that I need to switch between two bank after flash write, as per reference manual//HAL_FLASH_OB_Lock(); HAL_FLASH_OB_Unlock(); /* Set OPTSTRT Bit */ SET_BIT(FLASH->OPTSR_PRG, FLASH_OPTCR_SWAP_BANK); /* Wa...
The calibration at a DIV256 works most of the time but some MCU must be calibrated with a DIV1 otherwhise I get an offset of zero. We use VREFBUFF as reference. We try to swap an MCU with good result (DIV256 worked). One MCU calibrated but with error...
