I have NUCLEO-144 H723ZG board. I created a frequency meter app for the NUCLEO board, but the quality of the frequency measurement a sinusoidal voltage is very poor. I have a generated 720mV RMS, 126.7Hz signal between 0 and +2.5V (max) biased to +1....
I am using STM32F429ZIT6 - NucleoI have TIM2 as master in encoder mode generating TRGO on OC3REF to TIM1 & TIM8 slaves in Output compare One pulse mode.I can generate pulses on both Channel 1 of TIM1 & TIM8 but I would like to have a ration:1 of one ...
I am testing Readout protect using STM32F103. When the watchdog timer function is stopped, both level �?0 → 1�? and level �?1 → 0�? of Readout protect are operating correctly.If level �?1 → 0�? works correctly, it seems that the program has been eras...
Hello,Im working on a multi-channel A/D DMA projectI updated the version of STM32Cube from STM32Cube_FW_H7_V1.9.0 to STM32Cube_FW_H7_V1.0.0Due to SW version upgrade,A/D calibration now times out and leads to an infinite loop.What could be the cause?
I am reading 4 values, AN0, AN1, Temp, and the Reference. (But reference may go away.) I am over sampling 16x. and eventually will be starting a sequence every 100 us. I wanted two buffers, so I could work on one, while filling the other. I thought a...
I have stm32f4 standby which works as expected if wakeup PA0 is low - my mcu wakes up once I apply high to PA0I have the problem if PA0 line is constantly high I get wake up right after standby. My understanding is it's supposed to wait for rising ed...
I am trying to create two PWMs with same frequency and different duty cycle. Since my alloted pins are from different timer channels, I am looking to create a master - slave timer with same PWM frequency and different duty cycle. Is there any example...
Dears,Is there any SMBus Slave read word and write block example and technical documents of STM32F407 for reference?I found AN4502 Application note, but it only supports STM32F0 Series, STM32F3 Series, STM32G4 Series, STM32H7 Series, STM32L0 Series...
Hi,I am using stm32h745zi controller in my custom board. I want to use uart in DMA mode.When i send data through uart i got an interrupt only for first time. How can i get Interrupt everytime. and how to use uart DMA in both cores(Both tx and Rx).
