I'm using a STM32L4P5G Discovery Kit board with the external OctoSPI PSRAM in memory mapped mode to store a framebuffer for a SPI display. The board runs at 120MHz and uses the board support file by ST for initialization. The SPI transfer to the disp...
Hello, I am using a NUCLEO L552ZE-Q board, can some one please tell me what are the maximum and minimum voltages that it is safe to apply to an ADC input without causing damage to the Microcontroller. Thanks in advanceStephen
Hello, I'm wondering why there are big execution times (peaks) when doing PIL tests because the execution times are smaller when doing SIL tests (no peaks). Please find attached the comparison between SIL and PIL. Do you have some explanation and som...
According to the OctoSpi Documentation, only one of the five phases needs to be active in order to configure OctoSpi. "20.4.3 OCTOSPI Regular-command protocol When in Regular-command protocol, the OCTOSPI communicates with the external device using c...
I've just noticed this: which is true, but shouldn't be in RM0090... :)JW
Hi,I am trying to measure the duty cycle and the frequency of a standard servo PWM signal (50Hz and 5% to 10% duty cycle) using STM32F446. I have configured the timers to be in PWM input mode, and I can read both the frequency and duty cycle. The mea...
I've got a strange situation with a custom board with two STM32F4 chips. My master STM32F4 transmits data over SPI in blocking mode every few 100ms. At the moment the data size is 12 bytes but in theory it should be any size. The Slave chip is in SPI...
From the datasheet PA0 is listed as a 5V tolerant IO (FT type). Does this maximum of 5V still hold if the pin is mapped to the ADC input? If not, what is the maximum reading for this case?
How to give the STM32L4 series LPTIM1 timer an initial value,It seems the register address is closed to the public
