First install in Windows PC, is CH341SER.rar &#8211;> Un pack\u00a0that file and inside you can find SETUP.exe<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">2. Double click and install SETUP.exe. This will install driver software for Arduino Nano to work properly<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">3. Now to upload into Arduino Nano the hex file &#8212;\u00a0F5NPV_v6.hex.\u00a0For that use the uploader program\u00a0called XLoader which can be found in XLoader.zip file. (All these files were shared by VU3AVE.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">4. After successful\u00a0upload\u00a0of hex file in Arduino nano, it is ready to be inserted in LMR SDR board<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Arduino board was connected to the desktop computer using Mini-B USB connector at the Arduino end and standard USB at the computer end. When the XLoader was used initially with the default baud rate of <strong>57600<\/strong>, it did not work. That baud rate is meant for older versions of Arduino bootloader. Then I changed the baud rate to 115200, it worked well. COM port is selected according to what is displayed in your Device Manager of Windows. Another issue was that the hex file was shown as 102 KB, while the upload value was only 28 KB. That is because the memory size of Arduino Nano is just 32 KB and the uploader uploads only the bare essential part of the original hex file.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After the initial power on of the LCD, I have followed the instructions from VU3AVE regarding uploading of the hex file to the Arduino Nano: 1.
