I'm trying to generate an arbitrary waveform on PA_5 pin, tim2 channel1 in PMW output, using stream5 channel3 DMAI tried to do exactly what is written on the application note AN4776 using a nucleo F446RE but it doesn't work here are all my code:dma.C...
Hello,I have problems to initialize my SPI1 interface, and send a request. My Logic Analyzer Says that, after powering without a STLink. SPI_HandleTypeDef hspi; RFM23::RFM23() {} bool RFM23::init() { hspi.Instance = SPI1; hspi.Init.Mode = S...
Hello!A simple setup to run the ADC1 in continuous conversion mode runs as expected, but the measured values are incorrect as inspected via the debugger console. When connecting the ADC1 input pin to GND or 3.3V volts the measured value doesn't chang...
Maybe in some register the baud rate is saved?
Problem type - ADC readings excess uncertainty when reading internal reference (channel 17) - got to this point after excess ADC reading uncertainty on device pins, trying to isolate cause.Hardware Details - small 2-layer board (about the size of a L...
//MASTER while (1) { /* USER CODE END WHILE */ ret = HAL_I2C_Master_Transmit(&hi2c1, peripheralNucleoAddress << 1, bufferTx, 1, HAL_MAX_DELAY); if (ret != HAL_OK) { strcpy((char*) bufferTx, "Tx"); HAL_UART_Transmit(&huart2, b...
Hi everyone, I feel like I am running out of options as to why this is occurring as the RM isn't that accurate to setup DMA + PWM using Timers. The goal is to use TIM15 as a PWM generator running @ 800kHz running until 24 pulses are outputted and the...
HiI have successfully managed to configure and implement a TIM4 channel 1 as a PWM channel and connect it to DMA. Upon disabling the DMA after a transmit, the output goes high - this was the default and is desired. However, I've taken this further to...
Hi, I am using DMA to generate an arbitrary waveform on PIN PA_8 using TIM1_CH1. My HCLK is at 180MHZ, APB2 timer clock at 180 MHz and APB2 peripheral clocks at 90 MHZ.Even though having this clock, when comparing the oscilloscope and the value of AR...
