VREFBUFF is not available in STM32L431RCTx series, in datasheet it tells that "internal voltage reference buffer is not available", is there any other option to give External ADC reference for this series of STM32.
I need to generate PWM on a non-PWM pinI know one method is to use an ISR triggered by a timer, but because I need to run the PWM at 10kHz, this will put a huge load on the CPU just to toggle 1 pin.I've seen examples of using DMA to send data to the ...
we are reading pH sensor by using nucleo 32L746RG.even though both VDD and sensor value looks stable on tester like 3.3v+-0.1mv/ 2v+- 1mv, the adc value shows about 10% up/down around the true value.the adc value seems to repeat increasing and decre...
As titled, with little definition, how do I configure the NVIC_Type struct ? Directly use the numbers that are difficult to maintain later? Or in fact they have official definitions, but they were hidden somewhere else ?And another question, where ca...
I use the UART RX DMA mode to receive the data from the peripheral. This peripheral could endless send the data after powering up. However after serval rounds UART IRQ handler execution, the UART port couldn’t enter the IRQ handler anymore while the...
I Want to use the TIM2 with two channels in "Input capture mode". CH1--> PA0CH2-->PA1 Now I have two trigger pulses which I will connect to PA0 and PA1, Signal at PA0 will start the TIM2 and signal at PA1 will stop the TIM2.So how I can get the count...
I am trying to use one of the Firmware Package demo projects using Keil v5. With the STM32F072 Discovery Board connected, the Device Manager shows the STM32 STLink driver is working properly under Windows10. In particular, I've loaded the DAC_SignalG...
Hello?I am a developer using the nucleo-f411re board.I had a problem while trying to update the firmware by cutting the st-link part. The firmware is uploaded successfully, but the result of the printf function is not printed on the serial monitor.Is...
My board is STM32F103C8T6.I am generating complementary PWM using TIMER 1 with DMA for changing duty cycle.to be precise SINE WAVE PWM (or SPWM) using CENTRE ALIGNED MODE 2.Now i also want to generate SQUARE wave from channel2 , the wave should have...
