Im having a confusion on my diagram about the EV2. Why does the EV2 happens during the transfer of data1? and it does not happen during transfer of data2? Or could someone explain about my master transfer diagram? the MCU model is STM32F302R8
master side :uint8_t TMP102_ADDR = 0x08;uint8_t REG_TEMP = 0x01;int result = 0x01;(result is numerical data which i want to transfer to another stm 32 ) HAL_I2C_Master_Transmit(&hi2c3,(TMP102_ADDR<<1),&result,sizeof(result),100);slave side stm 32 pro...
Hello. I have written a program to run the DAC in the STM32F107VC and I have used STM32CubeMX and HAL functions. But I don't see any waveform in the DAC output (PA4 pin). I was able to run the DAC using set the DAC registers. But I don't succeed with...
I am struggling on SPI Master receive on STM32F407-disco board.I plan to interface to the microphone using SPI2 master receive.I setup the DMA but I always get to HAL_SPI_ErrorCallback().I setup the same setup using Nucleo-G474 but it can go to HAL_S...
Hi forum.. I developed a bootloader for flashing a hex file present in usb key. The text from the usb key is transferred via UART to another micro.. The bytes are then flashedin the flash area.. You can find the HEX file in the usb key here ..When I ...
Several MCU are described with the label 'value line' but I could not find an explanation what that mean. I assume it is related to a system architecture, right?
Hi folks.. I did a bootloader for the STM32F4 microcontroller.. I read a text file and I flash the bytes.. i really don't understand the following parts of the HEX file ,.. :020000040800F2 :040000050800ACB98A The other parts of the fix are addre...
