器件型号：TRF7970A 工具与软件：
您好、先生、
您知道如何通过 MATLAB 与 TRF7970AEVM 通信吗？ 我知道我应该发送什么命令、但芯片完全没有响应。
clear all;
clc;
ports = serialportlist;
% Set up serial communication (assuming UART interface)
s = serialport(ports, 115200, "Timeout", 3); % Modify COM port as needed
% Function to send command to TRF7970A and read the response
function response = sendCommand(s, cmd)
write(s, cmd,"uint8");
pause(0.1); % Small delay to allow processing time
response = read(s, 32, "uint8"); % Adjust read length as needed
end
% 1. Send a simple command to test the response
% Example: Send a command to read a TRF7970A register
simpleCmd = [0x01 0x08 0x00 0x03 0x04 0xFF 0x00 0x00]; % Example: Idle command
response = sendCommand(s, simpleCmd);
% Display the response for debugging
disp('Simple command response:');
disp(response);
