I am using TIM1 for medium-frequency PWM and TIM8 for high speed ADC sampling with a STM32F765VIT6. TIM8 triggers ADC1, ADC2, and ADC3 where DMA streams collect the data. The frequency of TIM8 is a multiple of TIM1 so once it is started it will remai...
Hello,I have been struggling to make this post because I wanted to post a very clear question after I had found the source of the problem. However, I have been working on this problem nightly for two weeks now and even still I can't pinpoint precisel...
First time i set up SPI, not using HAL.In the debug, i see that not a single bit is set.What am i doing wrong? SPI_HandleTypeDef spiHandle; spiHandle.Instance = SPI2; // SPI_CR1_CPOL SET_BIT(spiHandle.Instance->CR1, SPI_BAUDRATEPRESCALER_256...
Posted on February 26, 2016 at 03:02The processor is an STM32F373VC using STM32CubeMX generated code with the FREERTOS option enabled. I have attempted to add the code: NVIC_PriorityGroupConfig( NVIC_PRIORITYGROUP_4 ); to the code in main.c as instr...
Hi, I'm working with a STM32F411RE6 on a pcb and i've noticed that trying to read an input from PB5 and PB6 just returns 0. I've tried fiddling with the registers eg. setting them to analog input mode, pullup, pulldown and left floating but none of ...
Hi guys,I am using the stm32f103rct6 microcontroller, and there is a hardware watchdog in the peripheral circuit to monitor the operation of the program, but after my program runs away, the watchdog will pull down the nrst pin flat, and sometimes the...
Hi, I am trying to sense a signal through TIM1 channel 1 by configuring as Input capture and Measure the signal frequency and Pulse width. Now I want to generate a signal with a phase delay after the falling edge of the input capture pulse. It should...
Hi, I am trying to communicate with i2c DMA without interrupt. My MCU is STM32G474RET6.I've read that it is possible but can't find how to do it. How can i communicate in slave mode with i2c dma? Since my interrupts disabled, can't use the callback f...
Hi We use an STM32L452 with an external LSE (32.786 kHz) oscillator. We would like to use PC13 as a GPIO input with interrupt. In the errata sheet for the STM32L452 (ES0388 Rev9) I find the following entry:“2.2.12 PC13 signal transitions disturb LSED...
Hi, I have a confusion between these 2 USART Block diagram. Figure 1 and Figure 2.Figure 1 shows that the flow of the RX is from RX ENDEC block -> RDR -> Receiver control.Figure 2 shows that the flow of the RX is from RX ENDEC block -> Receive shift ...
