In normal times I would never thinking about buying from a no-name small Chinese seller, but I'm very desperate ATM
I am having this problem with a variety of signals but let's take for example a 10 kHz signal. I am using the repetition counter to count 9500 times (950 ms) and then be off for 50 ms before turning back on. During the repetition counter part my sign...
The IRQ is setup as follow:__weak HAL_StatusTypeDef HAL_InitTick(uint32_t TickPriority){ /*Configure the SysTick to have interrupt in 1ms time basis*/ HAL_SYSTICK_Config(SystemCoreClock/1000U); /*Configure the SysTick IRQ priority */ HAL_NVIC_SetPrio...
Hello,I am using an STM32F103RB MCU in a specific Hardware design.The Hardware was always working fine (it is a final product of medical customer) until I flashed a software which implements the stop mode (deep sleep mode) management (by setting the ...
Hello,I have a G431 working with TIM8_CH1 and TIM8_CH3 generating DMA interrupts for a peripheral to memory transfer. I am not getting the correct number of transfers on TIM8_CH1 which is a capture compare triggered by an external input pin. TIM8_CH3...
Hello,On a pcb on which there is the STM32F030K6T6, I am facing a strange issue.First, the context is that I am using different timers, interruptions, DMA, UART, analog inputs and digital outputs (PWM, ON/OFF signals).2 of the i/o's are concerned by ...
I have two device on the Rs485 line, one of them transmit the data, another receiving the data.Transmitter, transmit rs485TxBuffer, it is include `uint8_t rs485TxBuffer[2]={0xAA,0xBB}`.I expect the receiver fill the receive buffer with these data. Bu...
