I have an interrupt which I'm trying to streamline (for an STM32F031K6). I am using some commands like GPIOA->BSRR |= (1<<4);and i was surprised to see how much there is in this command in the disassembly. Is there any faster way of implementing thi...
Hello everyone, I have currently two issues with the STM32F411CC STOP mode, it could be great to have some support.I want to wake up each 1sec by an RTC interrupt. Here is my sequence to enter STOP mode:Clear RTC_WUTF flagClear PWR_WU flagEnable wake...
I'm trying to program stm32h750vb to run ws2812b RGB LED. My RGB LED is connected to TIM1CH2N. I'm unable to generate desired PWM signal with my DMA settings. I have tested PWM signal without DMA it is working fine. So, as per my knowledge my timer ...
I use the STM32F7 and I want to change the baud rate of the USART6 from 115200 to 921600 during runtime, how can I do that?
I would like to attach 2 high speed A/Ds connected via parallel GPIOs and run them at 50 MHz each, or 100 MHz aggregate. One A/D is 12 bit and the other is 8 bit so I could take advantage of FIFO packing on the memory side. The capture buffer size ...
I've been wondering this for a while. Are there any restrictions on the US government or its contractors with regards to using STM32 chips in their hardware? For instance, would there be restrictions against a government contractor developing a new s...
Hey There,Ive got a Semtech SX1261 Board (LoRa- tranceiver) and iam trying to read its registers with my STM32L432KC (with SPI)Ive got working arduino code to read all its registers, but its giving me different results when i try the same thing with ...
Hello everyone,I'm using STM32F429 MCU (STM32F429I-DISC1 board). I was generating PWM signals on PA1, PA2,PA3 and PA5 using TIM2 ... The important part is that the PWM signals on PA3 & PA5 are fine where the high digital state is at 3.3V. For PA1 & P...
I am using Stm32l0 and am receiving data from GPS via uart but I am facing this problem.uart receives the first byte and then repeats the number of bytes it wanted to receiveFor example:AL_UART_Receive (& huart1, buf, 80, 200);It receives the first l...
I have an RS485 device, the time for which it turns on is about 3-4 seconds.In response to a request, it can send an indefinite amount of data, so I run HAL_UART_Receive_IT with a margin of a few bytes.But I only receive 1 byte and then an OVR error ...
