The PKA peripheral can precompte the montgomery parameter, which is documented as "R2 mod n". If I compute this offline with R being the normal (2 ^ b) [b the numbers of bits in the modulus n], I am getting a different result than what PKA computes. ...
Hello everyone! Currently I'm working in STM32L496ZG-p Nucleo board, I have written code for both MCU specific header file and Driver specific header file and I started to build a simple project to make a LED blink. But I haven't got the proper resul...
Hi all.We are using a bidirectional UART with hardware-flow control lines (RTS/CTS) between two microcontrollers.One of the controllers (A) is an STM32H7, the other controller's type (B) should not be relevant. I write this from the perspective of A....
Hard fault with DMA on TIM3_CH2 (but on TIM1_CH1) for WS2812B LEDsI am trying to control WS2812 addressable LEDs. This example (Interface WS2812 with STM32) works great using TIM1_CH1 to generate a PWM signal on output PA8. It uses DMA to adjust he d...
I have been reading a bit about neopixels and the communication protocol they work. I have been searching for a library for the WS2812B neopixel but could not find one that would work out of the box hence I have decided to write my own neopixel drive...
Hi! i am doing example pwm ws2812 with dma, configure the time 1 with ARR=60, using clock= 48 mhz, my pwm not working full buffer i don´t know why not work full buffer, the pwm have 12 pulse, i am sending for one led ws2812 is 24 pulse./* USER CODE ...
I'm trying to do some debugging using SWO on an STM32G474. After a very short amount of time no new packets are displayed in CubeIDE (usually after ~2500 packets). I limited the SWO frequency to various values between 100kHz and 8 MHz. Using an oscil...
Hello,I am using STM32U575 and would like toimplement a PWM output. This should also work in Stop2-Mode.Clock for the LPTIM is LSE. It works with LPTIM1 and 3 without any problems.To generate a PWM in Stop2-mode, I use the LPBAM with LPDMA. Now I wou...
Hi there;I have been trying to get analog signal from three channels on my STM32 for 2 days. I could get the signal from each potentiometer using polling with single channel conversion, but when I try to use multiple channels with DMA, all I get is z...
page 1320; timer 2 input pwm mode"1. Select the active input for TIMx_CCR1: write the CC1S bits to 01 in the TIMx_CCMR1 register (TI1 selected).2. Select the active polarity for TI1FP1 (used both for capture in TIMx_CCR1 and counter clear): write the...
