Hello,I am implementing a Modbus Master on a STM32F722. First, transmissions and receptions were managed through Rx/Tx interrupts. But as I got a lot of overrrun errors while getting my slave's responses, I decided to transfer received packet through...
Hello.I am creating a board with an STM32H7R3Z8J6. I am wondering what I should connect DVDD to? My intuition and "experience" says that this is the "Digital power supply pin", but it doesn't really make sense to make that distinction on this type of...
Hi all,I am using a mass-produced PCB board for a project, the chip model is STM32F429BIT6. The PA1 pin is used as ADC1-IN1 for access to the sensor.However, I found a strange phenomenon that after configuring the ADC, the initial reading of the pin ...
Hi,I need to implement a Bootloader for an STM32L452RET6 as follows:- using a uSD card over standard SPI (not Quad SPI)- using the BOOT0 pin option- using the ready available ST libraries My questions, if someone could please help out, are:1) which l...
So I’ve been following a udemy course and I’ve been picking things up and learning how to change registers for peripherals and how to enable them and such but the course just tells me what I need to enable bit wise to enable the specific peripherals ...
Hello, I have an issue with my code where I have configured SysTick and it triggers on every clock cycle, but I dont know how to make things trigger inside the main while loop #include "main.h" #include "functions.h" #include <stdbool.h> #include <st...
The QSPI is working fine, I can write and read using the standard library.But when using external loader, it can never write the data correctly, though I can read using Cube programmer.this is the data I am getting instead ofI am using the loader fil...
Posted on July 06, 2018 at 16:09Sorry for my stupid question, but this makes me really confused. I was just looking for the the bus with connected with the EXTI, then I found that APB2 bus is connected as it is shown in the reference manual in here ...
Hi, I am using battery voltage charging as a part of my project. For some reasons my voltage reading in the prototype is 1.18 V and the ADC reading in my debugger is 1.25 V. This totally different for different module. Physically all modules are meas...
Any writes, erases or reads to flash range greater than 0x8100000 fails. When I inspect the region via Memory browser in STM32Cube IDE all memory beyond 0x8100000 appears as a "?" indicative that a read is not being allowed. Being new to this control...
