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...
Hello!I have strange issue with DMA mode for UART7. I have callback for data transfer complete, but if i sending new data - i have broken data. If i added timeout - all data sending Ok.does anyone have any thoughts?
Hi,I want to implement custom bootloader in STM32H730ZB, It has 128KB of Flash and only one sector. If I want to load image using bootloader then, I need to erase particular portion of flash. Is there any support to erase flash by flash word? If I er...
Hi guys,I'm a little confused about the trigger voltage for rising-falling triggered interrupts. As my previous understanding, the trigger voltage should be Vih and Vil. But some one told me Vih and Vil is not for edge triggered interrupts. The thing...
I want to interface to an existing RS-485 bus where the 9th bit (normally reserved for parity) is set to 1 for the first two packets of each frame (as an addressing mechanism) and then cleared to 0 for the subsequent "data" bytes.If I set PCE=0 in r...
I need the callback, to clear the cb4.DMA_Active flag and update a pointer when it finishes. I cannot step through it because it starts sending data over and over as I step through it and does not call the callback. First time msg points to "12345678...
