I want to build a GUI software by myself not supported by TI, and the software can receive directly data and analysis data from AWR1642 ES1.0. So I need to know the protocol when Eval board transmits data to PC by UART. I'm closing this thre...
Hi, I am trying to read two analog channels using the ADC_Measurements APP in my H-Bridge 2 Go kit and send it via UART to my PC to debug the data.
The purpose for this project is to learn how to configure the UART device on the STM32F429ZIT6 development board. There are several exercises to go through in order to understand the way UART device on this microcontroller works. The transmit and receive of data between the UART and PC is...
The high throughput UART to DSP interface (UDIF) maintains UART functionality while integrating dual Transmit (Tx) and Receive (Rx) FIFO buffers that are optimized for more efficient interaction with their respective I/O processors. The portion of the interface design interacting with the DSP, the...
Why does the XPS UARTlite v1.00b not transmit any data during HDL simulation? Solution The status_reg signal in the uartlite_core.vhd is not properly initialized. To work around this problem and maintain the current hardware functionality, perform the following: 1. Open C:\Xilinx\10.1\EDK...
