Hey guys.After having a lot of problems i had with fmc and nand flash finally i made it work.But when i was looking at HAL_NAND_Read_Page_8b hal function i saw that instead of using CMD_AREA for read command 0x00 it uses ADDR_AREA. But read and write...
Hi, I am trying to measure the amount of time between the rising edge on two different GPIOs using TIM5. one assumption I make is that one of those GPIOs will happen first. Actually 3 gpios are involved in the application, PA0, PA1 and PA2, PA2 is co...
Hi everybody!First of all sorry for my language. I just started to learning programming of STM32. My problem is that i made a delay function. I wanted to test it with the input capture mode. I setted the prescaler to 16000 - 1. I wanted to get an 100...
Hey everyone. During my work with the RTC on the STM32H753, I've noticed that you can't set the century or millenium in the Date Register (RTC_DR). Is this correct?Therefore, I can infer that the hardware is hardcoded to work within the 21st Century,...
Hi, I've designed a custom board that has a STM32F411 and a STM32f446 on it. I would like to be able to have customers update the firmware on the boards as easily as possible. Currently, I program the chips using an ST-Link but can also program over ...
Good morning when compiling a project to which I added files (.h and.cpp) returns the error of "undefined reference" on a function that is in these files. I also add that I added other files (always .c and.h) of which I called a function without havi...
Is it OK to tie NRST lines together for 2 or more processors ?In this case, they are STM32F042C6T6I would think so but just thought I'd ask.boB
I use pin PB4 on STM32G474QE as normal GPIO output. The external load is ~20kOhm to GND.There is a strange behaviour after reset without any further initialization:1. It seems to be an internal pullup <10kOhm that drives the output to high2. Another ...
I need to hook few external signals to STM32H7x3I-EVAL rev. E, if possible without soldering or losing access to FMC, QSPI memories.This board is much busier than Nucleo, I can find only few free pins on the default pinout.The user manual (UM2198 rev...
HIWe bought a AMT102-V encoder from CUI devices. It is a 1024 pulses per rev encoder.We are using a STM32H745 nucleo board and the HAL library with inbuilt pulse detection for quadrature encoders. Code is being run on the CM7 core.Every pulse increm...
