Im trying to write to and read data from 10 eeproms in parallel. I first transmit the data in parallel to all the eeproms via spi, I then read data in parallel by first transmitting the address of data stored in the eeprom and then transmitting dummy...
I know its clock is provided from the APB1, but I can't figure out how to calculate and what are the relations between fdcan_ker_ck and fdcan_pclk
Hi to all!I have an Nucleo-F767ZI board and I noticed a problem, in the I2C1 periperical.I have redirect the I2C1 pins on PB8 and PB9 for comodity and left PA6 and PA7 free and the I2C1 work well.After a couple of days, i have used the PA6 pin as out...
Hi,I would like to have more informations about the both integrated comparators in the stm32l052 because we only have the propagation delay informations in the stm32l052 datasheet.I would like to know the rise/fall time and propagation delay vs. over...
I have noticed some very strange behavior with the I2C controller. It appears that when it has a slave address match, it sets the ADDR ISR flag and raises an interrupt ( if enabled ). If I have a breakpoint in the interrupt handler, the ISR BUSY fl...
https://www.st.com/en/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus.html#resource tells that REV 3 is available. However the version that I can download is still Rev.2
I've been struggling for quite a while now on my SPI setup.The setup is as follows:- SPI Slave is a Nucleo STM32H743 in simplex mode, clocks at maximum (sysclk 400MHz, hclck 200Mhz, APB clock 100MHz)- SPI master is another identical Nucleo in simplex...
Hello. I have the following scheme for reading the output of humidity sensor that communicates via I2C:How would I execute this sequence with STM32CubeMX IDE and HAL libraries? The output of the sensor is as follows: All I have now is this code: uint...
I'm trying to erase the entire eMMC chip using an STM32F405.I send CMD35+CMD36+CMD38 and get the expected R1 response from all 3 commands. After CMD38, the D0 line goes low to indicate the chip is busy erasing. About 1000 SDIO clocks after CMD38, the...
