I've been trying to run the fmc and lcd over an 8-bit data line for a few days. Yesterday I managed to read the ids of the lcd correctly, but because I messed up the timing settings of the fmc (timing settings were working randomly), I can't get any ...
I am working with a STM32H723 micro, capturing 2048 samples of data on ADC3. The ADC is triggered by the overflow of TIM1 and transfers samples successfully the first time HAL_ADC_Start_DMA(&hadc3, (uint32_t*)adc_buf, ADC_BUF_LEN); is called.In the H...
I have Nucleo-H563ZI board and I'm trying to power it through external 5V source (E5V). When I connect the 5V power source and set PWR SEL jumper (JP2) to E5V, I can see the power LED (LD5) light up and even the ethernet controller seems to be active...
I am using STM32F103ZGT6 I have initialize code From STMCubeMx with settings-> PLL -ON , HSE -ON , LSE- ON for Internal RTCI have written code to retain date for internal RTC. I want the event when RTC switches from VDD to VBAT , as per my applicat...
Hello.I am developing a product with STM32F769I-DISCO development kit.Unfortunately, by my mistake, I think I connected 24VDC to the power terminal, so I couldn't use the power IC that looked like a regulator marked U4.Can you check the exact name of...
Hi,Im using stm32h7 mcu for my project.Which is an iot product.I need to use low power mode on it i need to wake the mcu using an gpio external interrupt or either by an uart .Device is switch to some mode with a constant current consumption which i...
With STM32L071, I've been fighting a problem of losing UART RX characters. The RX path uses HAL_UART_ReceiveIT to queue a single character buffer, and then re-queues it from HAL_UART_RxCpltCallback. The received character is then stored in a software...
I was promised the recording, presentations and a voucher but never received any. Where can I get thesr?
