Hello everyone! After countless hours of self-grind, talking to different LLMs about it (and mostly failing), I may have started to get some faint idea about what I am doing. I am mostly writing this post for a sanity-check. Currently, for a medical ...
I'm getting unexpected signal in PWM output on timer1 channels.Signal screenshots are attached.getting unexpected signal (around 500nS) in between PWM duty cycle pulse. Below is timer configuration : NOTE*: CCR values changes with software as require...
For my project I'm using an STM32F743VIT6 with ADC1 and ADC2 in 16-bit differential mode.In the reference manual (RM0433) §25.4.7 it is written:Converted value = ADC_Full_Scale / 2 x [1 + (VINP-VINN)/VREF+].For 16 bits, ADC_Full_Scale is 0xFFFF. What...
Hello,I have a question about the usage of the MCE in the STM32H7RSI have the STM32H7S78-DK boardI'm starting with a project that show images to LTDC with images on the flash (copy with DMA2D) and the framebuffer is on the PSRAM.My project works with...
Hi All,I have written a baremetal code to initialize the USART2 of STM32F401RE and print HELLO WORLD. The code does not use HAL and rather accesses and writes to USART2 peripheral registers using the C pointers. I have cross verified the code multipl...
I'm working on a DMA routine for my SPI DAC, and I've loaded up a buffer with the commands to make a sine wave. But when I check it with the oscilloscope, it's just stuck at 2.05V, which is actually the very first command in my sequence.I've spent ho...
Hello,I'm attempting to make my MCU shift between STOP and RUN mode using a button. When I press the button the CPU stops, however, upon pressing again it fails to start the CPU. I know this form the LED indicators.The strange part is that when I pla...
Split from How to make the FDCAN with DMA - which is solved.TL;DR: STM32s don't support DMA for CAN or FDCAN.Hi, thanks for the clarity.But, the doubt I'm having was, then how to handle that much data rate like eg.5mbps in FDCAN without any help of D...
[Request]I would like to know the correct procedure for initialization using the INIT bit of the FDCAN's CCCR register.[Situation]1) To reset the FIFO status, we are only performing the initialization start using the INIT bit of the FDCAN's CCCR regi...
I'm having problems enabling USB on STM32H503. This happens on both my custom board (STM32H503CBT6-based), as well as on MB1814B (STM32H503RBT6-based). I observe no USB connection, no USB IRQ being invoked, no hardware handshake. Here's the simple...
