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...
I aim to set the IWDG (Independent Watchdog) to STANDBY mode to ensure that our MCU remains in that state without being awakened by the Watchdog. To achieve this, I utilized the following command with STM32_Programmer_CLI.exe:After executing the comm...
My STM32F0 won't show up under "Ports " in my device manager. It does, however, show up under "Universal Serial Bus Devices". I'm trying to print to a serial monitor. I've spent over 12 hours (low guess) trying to troubleshoot this issue. Here is wh...
In RM0351 Reference manual Figure 420. USART block diagram, the positions of shift registers and data registers (of both Transmit and Receive) are wrong; their positions should be swapped.
