I read the code of Uart echo program in the tiva C, and found the code below, there are ROM_IntMasterEnable(), ROM_IntEnable(INT_UART0) ROM_UARTIntEnable(UART0_BASE
I have plenty of GPIO spare so rather than add gate hardware to enable and disable 1 of the 3 multiplexed channels, I thought I could use uart_set_pin(...) to assign my UART to different sets of GPIO pins for Txd, Rxd and RTS (for RS-485 TxEnable). I don't use CTS so have...
We want to perform these in the MCU that before and after stop mode Many thanks. Regards, HMYu +2AL_Renesas1 年多前回复HMYu Hello HMYu, I attach pins setup for uart configuration. You can also find it on...

Introduction There are many possible ways to access the System Bootloader in STM32 devices and, in this tutorial, we will cover how to easily perform
The timer counts once the TE bit is asserted, once the timer reaches TCMP value it wraps around and can optionally generate an interrupt by asserting INTE. This also toggles the Q and NQ lines that come out of the timer and are routed to pins on the board (see the constraints filetop....
Description When using ESP32 and RP2040's UART for RS485 communication, how to handle the fast flipping of RE/DE pins, the different transmission speeds at different baud rates, how to know whether all data on UART has been sent, and how...
GPIO 33 – Built-in Red LED There is an LED red colour on the board near the reset button. When shining bright, it indicates that there is some operation going on. UART Pins There are two interfaces of UART, UART0 AND UART2 on the ESP-32 S chip. TheGPIO 1(Tx),GPIO 3(Rx), an...

Some I2C devices have additional external "address pins", so as to operate more than one device on a single I2C bus. If this applies your device, check the required conditions (pull-up/pull-down) are met. In general, getting such low-level busses like I2C or SPI are almost impossible ...
