i am using stm32f207ve microcontroller ,im receiving continuously data from another controller using 50 buffer using interrupt, after the 50 buffer is filled then again the data not receive in buffer 0 ,what i do now????
I have setup a STM32L0 as a slave to another micro. The ST must reply to the master with requested data received from a wireless source using SPI. I can get the received data easily. The transmit is sending nonsense to the Master from the ST uC. The ...
Hii All,The requirement is,1) 12 Capacitive keys 2) 12 GPIO3) I2C4) Sleep/Deep sleep mode current : less than or equal to 5 micro-ampere.5) Active mode current : - 20 MiliampereKindly Suggest the Ultra Low power controller part number. Regards,STAR...
I use STM32F429BIT6 controller in our instrument. When Power is ON after initialization STM32F429 controller is Reset. This happen only Once time after power on the instrument. It is not continuous reset.What can i do
For example, here is the function definition for the STM32H725:/****** TIM Instances : master mode available (TIMx_CR2.MMS available )********/#define IS_TIM_MASTER_INSTANCE(INSTANCE) (((INSTANCE) == TIM1) || \ ((INSTANCE) == TIM...
Hi Team,I am using Smart battery in my product. While reading the battery voltage or current I'm getting the PEC error in smbus line, but the received PEC value is correct. In smbus line three devices were connected, Host(mcu (stm32h7)), Master(Batte...
Hi,everyone.I'm use NUCLEO-L496ZG platform.ADC1 sample at a frequency of 5M,ADC3 sample at a frequency of 12.8K(PWM trigger).when only run ADC3,ADC3's waveform is normal.when ADC1 and ADC3 run at the same time,ADC3's waveform has a lot of interferenc...
Recently, I've been worked with the esp8266 and stmf407 discovery board.I used stm32f407 (master), and connect to esp8266 (slave) via SPIHowever, the package I got always missed 1 package. To be more specific, I've tried to send some uint8_t dummy da...
I'm looking to use this controller for aerospace applications and was wondering if there was any performance data at the -55`C temperature extreme. A required warm-up period or something similar is what I'm expecting to need, but any more detailed in...
Hi,I have a problem When I use Dac output of stm32h7 . Dac output go high (3.3v) for 200ms and then it go to adjusted value. Why?How can I prevent this event?
