Hi!I am new to Microcontrollers so the question could be not really exciting but I think it could help me to understand how clock and timers work. I want to toggle the LD2 every 1 sec through a TIMER. I have set up the SysClock at 2MHz and a TIMER r...
I am trying to wire a graphics application on an STM32H745i-DISCO board, and place the framebuffer in external SDRAM.So I configured the FMC as follows:Then, under Cortex-M7 I set up the MPU:But when running the program and attempting to write to 0xD...
Hi ST,Using the STM32L476 for a custom battery-operated application, on trying to implement the USB 2.0 through a type C receptable, I need clarity on the connections of the USB.AFAIK the VBUS sensing on PA9 should be connected through a resistor div...
I’m working on a project using the STM32F446RE microcontroller and I’m trying to set up the debugger's printf viewer in Keil MDK. I would like to use the printf function to output debug information to the debugger’s terminal.I’m having trouble seeing...
Are there any guides or tips on making an STM32 MCU last in a high temperature (~150°C) environment? Specific voltage or clock speed tweaks?The MCU would sleep most of the time, but now and then take and store some measurements.Would certain families...
Hello,I'm trying to record the execution trace of my firmware running on a STM32H753. For this I'm using the ETM functionality of Cortex M7. I don't want to use external tools but rather to use the ETF (Embedded Trace FIFO) that can be accessed direc...
I am in the early stages of writing an application that writes audio data to an SD card and, on request from the RPi, writes the same data from the SD card to the Pi. The project requires that it's done this way, as I would like a copy of the data on...
Hello,I'm following this example: How to use the STM32 ADC's internal reference volt... - STMicroelectronics Community I'm using ADC4 rather than ADC1. I checked off Vrefint Channel and Vbat/4 Channel, and I let the IOC take care of the sequencing (i...
Greetings,I tried to setup a L0 using SPI to connect with LSM6DSR, all codes are generated using CubeMX (also the driver code for LSM6DSR with X-CUBE-MEMS1)The weird thing is, when ever it tries to utilize SPI functions (Transmit, Receive, and Transm...
Hi,I'm getting this below compile time errors... undefined reference to `MX_RTC_Init' However, I have included the rtc.h header file, which contains the declaration of the MX_RTC_Init(void) function. #include "main.h" #include "cmsis_os.h" #includ...
