Hello everyone,I am fairly new to embedded so bear with me. I am trying to understand bare metal programming.So basically I managed to turn on the LED on soldiered on the board (PA5) but now am trying to create a delay using basic timer TIM6. My issu...
Hi there, Ive gone around in circles for hours on this. I'm just trying to read a frequency, around 150Hz typ. using the 32 bit timers, for now just TIM2, 4 channel but behaviour same on all channels. Using 16MHz clock the timer overflow happens arou...
Hi everyone! I designed the board shown in the attached picture. It’s built around an STM32H745 microcontroller, along with crystal oscillators, a DAC, an EEPROM, and an NE555 that generates a reset signal when a button is pressed long enough. Afte...
My colleague is working with the stm32h743.Initially PC7 was setup as a PWM output. That worked fine.When he changed the pin to GPIO_output, no code was produced to set up the pin.By manually entering code, we could get the pin to be configured as w...
Hello @D.Botelho @mƎALLEm I had an issue of ThreadX and FDCAN transmit as below.I use the stm32g474 and config a threadx and fdcan with stm32cubemx, so far it works well.but when i add some fdcan transmit code, it comes strangely.the code as belowvoi...
Hi, I'm trying to communicate two microcontrollers (STM32H503CBT6 and a NUCLEO-H503RB) via FDCAN but the STM32H503CBT6 is not sending any messages.Both have the same configuration, but the NUCLEO-H503RB can send (I have checked it with an oscilloscop...
The goal of my project is to turn on an LED on the recieving side through CAN. Both my reciever and transmitter have the transciever circuit. Both are Nucleo boards, TX: F303RE, RX: F446RE.The data i am sending through is 16-bit, but as long as my re...
Dear all,I am facing very poor performance with the STM32N657.I have some benchmarks that manipulate arrays of data in different ways.I ran these benchmarks onNucleo_H753 @ 480 MHz, with caches ONNucleo_N657 @ 600 MHz, with caches ONFor the STM32N657...
Hello, I am starting a timer interrupt to send data over can data at 50 ms below is the configuration for the same and callback function when pulse is complete volatile uint8_t send_ch0_flag = 0;volatile uint8_t send_chx_flag = 0;volatile uint8_t se...
Hi,I’m using an STM32U385 (Cortex-M33) and trying to enable the Micro Trace Buffer (MTB) using ARM’s MTB-M33 register addresses (0xE0043000 base).No matter what I try, the EN bit in MTB_MASTER never sets.Does the STM32U385 have the MTB component?Than...
