I'm currently using STM32l496G-DISCO for my project which requires to sample an analog signal and get certain amount of samples in certain time. I tried doing that using a PWM generated by a timer and my ADC1 is triggered by timer1. Activated DMA to ...
Hi,I'm trying to talk to WS2812 RGB Leds. I'm using TIM1 CH3 PWM Output with DMA. Everything looks almost fine. I'm always sending the same data using:HAL_TIM_PWM_Start_DMA (&htim1, TIM_CHANNEL_3, (uint32_t *) pwmData, (24 * NUM_OF_LEDS) + 50);Here p...
Hi,I'm tasked with creating the documentation for assesing the compliance of our product in regard to EN18031.The standard requires us to have checked if the relevant hardware has any publicly known security vulnerabilities. But when I asked our hard...
Anyone familiar with using I3C in HAL? I'm using I3C to talk to an IMU sensor and I got through DAA and can successfully perform private reads (can read from whoami and other registers also tested) but I couldnt get private writes to work.I followed ...
GreetingsI am using STM32F030C8T6TR for ADC on two channels IN1 & IN3. It works. However I wanted to add DMA. When trying to add DMA , It shows on two channels channel 1 and channel 2 , Though the datasheet mentions DMA is available for 5 channels. I...
Hi ,We are working on configuring an ISSI Octal Flash memory in DTR mode on the STM32U5 platform and would like your assistance. We successfully executed the example provided for Macronix in document an5050 example (II. Octo-SPI FLASH in Regular-comm...
Hello,I am trying small example LED blinking written in assembly only - see below. LED is placed to PB15. I am able to compile the program without error using this commands:arm-none-eabi-gcc -save-temps -nostdlib -nostartfiles -mcpu=cortex-m3 -ffrees...
Hi,I'm new to the ST32 world and would like to know if this is possible before I start experimenting with an STM32F405:Is it possible to use both USB interfaces as a USB host at the same time (only full speed and low speed, no high speed is required)...
Trying to make a phase shift PWM for a DAB converter, i managed to do this exact functionality with normal TIM1 (Asynchronous mode), but im very very lost with HRTIM. I am able to produce complementary PWM signals for TIMA1 and TIMA2, and TIMB1 TIMB2...
Hello,I need to understand the implementation of using output compare with timers as a basis to tackle a more advanced project. My start point/goal is a timer with a period of 3 seconds and it toggles when CNT equals 800ms(CCR1). Clock is running at...
