STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello everyone,I successfully used USART1 and USART3 in my application. However, when trying to use USART4, Rx is working but not Tx. The idle signal stays at 0V all the time. Here is what I already check:UART initstatic void MX_USART4_UART_Init(void...
Hi... Greetings... We're planning to use STM32H503 MCU in our application. To brief about our application, we've a parallel RTC IC which has gone EOL. This RTC receives commands from the motherboard MCU. So, we're mimicking the RTC's functionality u...
Hello, I want to communicate with a PC using FDCAN with the Nucleo-H743ZI2 development board. According to the information I found,the STM32 board requires a transceiver for CAN communication,and since the PC does not have a CAN port, a CAN to USB in...
I'm using the stm23F103C8 and I would use the RTC internal cloak/calendar. The program is working fine and I have used the LSE osc (32KHz..) as clock source. I have connected a 3V battery to the VBAT pin. My problem is that the switching off the main...
Dear all,i have a custom pcb with a STM32H753XIHx.I want to use CAN1 Interface to receive PDO and SDOs (Baudrate: 125k, CANopen).My receive routine looks like this: // CAN 1 receive interrupt callback void HAL_FDCAN_RxFifo0Callback(FDCAN_HandleTypeDe...
I am using ADC channel with DMA to get linear hall sensor data ,its giving bur after some time adc pin not working. but same code working with another board, what can be problem.
Hello,I have an STM32F107 microcontroller that uses DMA and USART to receive 250 bytes every 10 ms. The RTOS tick is 1 kHz, so osDelay(1) results in a delay of about 1 ms.The sender transmits 200 bytes every 5 ms, and during this phase, it is not cri...
Hi i am struggling to make SPI work on my nucleo-h723z board. I am using Cubemx to configure and i press when asked to used the default setup for the nucleo board when creating the project.CubeIDE is v. 1.15.1CubeMX is v. 1.11.1my code is very basic:...
i am using STM3210e-eval board which has stm32f103zgt6 MCU no i am just sending data over uart to my pc the uart is interfaced with rs232 port so for the looking at the schematics i have connected it's tx and rx to ft232rl's rx and tx respectively an...
We use a STM32F7xx microcontroller with LQFP144 casePart of the ADC Pins are on the 1-36 pin side.Unfortunately this is also the side where the Quartz (Pins OSC_IN and OUT, PC14-OSC32_IN, PC15-OSC32_OUT) and the RMII_CLK are mapped.This leads to add...
