I am using STM as i2c slave. When other i2c master reads, first byte is always 0xFF and rest are correct data from STM with 1 byte shift so master needs to read 1 extra byte. Also I get HAL_I2C_ERROR_OVR error during that. Please suggest.
Hi,I'm having an issue which I can't seem to resolve:I'm trying to change the output value of Pin9 (Port C) through an interrupt routine (TIM3).If I put a simple XOR statement for this pin in the interrupt routine it works as expected.However if I tr...
I have configured the UART for multiprocessor communication over RS485. I can receive and transmit data correctly, but if the data contains a '1' as MSB it is interpreted as an address. Now it is clear from the documentation that this is the correct ...
Hi, i need to measure rms voltage and current choosing ADC channels in stm32f103.i selected two channnels in ADC1 to read adc values . By using these channels i need to calculate rms voltage and current . But i am confused how to do it . is it nec...
Hi,I am trying to implement CAN bus using STM32F072RBusing normal mode.I have found successfully transmission & reception from both the nodes.I am having one doubt regarding the frame formation.CAN is having the format asSOF|11 bit identifier|SRR|IDE...
hello, I try to use the AD9834 with the nucleo L476RG and I have some issue. I use Spi 1 , send that I think good, but it's not work.here are my code, I hope someone can help. thanks and sorry for my englishint PINSW = 1; //int led = GPIO_PIN_5; in...
I am using NUCLEO-L010RB.When operating RTC (standby mode) using LSE,What is the current consumption during RTC?
Hi,In STM32L073, the ADC conversion time is stated as 0.875us with 12-bit resolution.Even in the actual test, it has been confirmed by the continuous operation of 1ch of ADC.However, I set the ADC results to be transferred by DMA, the ADC conversion ...
I want to generate a PWM signal through the Timer.(STM32F104RB) In CubeMX, "channel 3" of timer1 (TIM1) is set to "PWM Generation CH3N", and "channel4" of timer1 is set to "PWM Generation CH4".The parameter settings are the same as shown below.(Presc...
