I have a new board design that interfaces an STM32L4A6 with a uSD card using 1.8V I/O. The SD Card is powered by 3.3V and supports the LVS mode of SD. The STM32L4 does not seem take account the SD specification 6.0. There is no auto detection mecanis...
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...
