I am writing to an SD card using the Adafruit_Shield BSP library on the STM32L4R5ZI Nucleo board. I had it writing 10 values, from 0x00 to 0x09 but the second byte (with a value of 0x01) was getting corrupted as set to 0x00. I changed the array so ...
Hi all, Working on STM32H745: when enabling the M4 at M7 main(), the 'D2 domain' SRAMs (1,2,3) are being reset, causing issue, as the M7 and the OS are using these SRAMs, prior of the M4 enable (RCC register). Is there any option not to reset the ...
I had a board assembled through JLCPCB, which included mounting an STM32L071. When the PCB arrived, I loaded a program with a blinking LED in an infinite loop. Unfortunately, the program didn't behave as expected, and during debugging, I encountered ...
Dear ST support team, I am using STM32-H755 for my motor control application. I am using Hardware Semaphore for synchronization between two cores. What I did, I developed the notification release in M4 in a timer interrupt routine as below: void TIM...
Setup:I am developing an application where the Nucleo-144 board sits in a cabinet adjacent to a computer. The Nucleo-144 board is powered externally via a 12v power supply. I have selected this with the vin jumper and confirmed that JP2 is bridging p...
STM32G051C8Tx: I am having issue setting up the global interrupt on I2C1. I am not able to find the EXTI 23 in the STM32CubeMx. It only shows up to EXTI 15.
I am trying to design a digital SMPS with an STM32G0.ST has lots of literature stating that the comparators can be used to control the duty cycle of the PWM from a timer.I understand the use of a comparator to detect a fault and output to the BKIN in...
I designed a board that uses the STM32G431C6 and is intended to connect in a chain with other similar boards, but I am having problems when powering them up. They turn on and work fine sometimes, but sometimes boards won't turn on. Each board I desig...
Hi, I have a TFT screen that is using 3-wire 9-bit SPI (DC bit as 9th bit) has anyone got and experience or examples of this with HAL? I think I have it explained below, the problem is when I test on the oscilloscope the SPI data is reversed as MSB i...
I took the default STM32F101VFTx, enabled PB8 & PB9 as GPIO Output, and then tried to pull the pins low. I am having an issue that caused me to create this isolated test. Configurations, code, and scope on the pins below. Repo for this test case ...
