Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems and a programmable graphic and text processing tool.<\/em><\/strong><\/span><\/p>\n

Bitmap2LCD : Serial Communication<\/h3>\n

 <\/p>\n

\n

The target here is to directly connect a serial Graphic LCD on a USB port of the computer using a FTDI chip based USB adaptation module<\/p>\n

Visit this Website for modules and and drivers :<\/p>\n

http:\/\/www.ftdichip.com\/Products\/Modules\/DevelopmentModules.htm<\/a><\/p>\n

The USB to UART Com<\/strong> option is already working while the RS485, I2C and SPI Serial Interface adapations are currently under development ( begin of 2017<\/em> )<\/p>\n

 <\/p>\n

In the same Window as the Text editor<\/strong> and the Hex Editor<\/strong> , there’s also a Serial Communication<\/strong> Tab and Panel. In the local Menu ( red arrow<\/span><\/strong> ) you can connect (open) <\/strong>the selected Serial Port<\/strong>.<\/p>\n

You can choose the Transmit Only<\/strong> or the Transmit and Receive <\/strong>mode. Remember that the Transmit and Receive<\/strong> mode scans the serial interface for received chars, this loop is computing time consuming. You can close the serial port<\/strong> to stop this loop when not needed.<\/p>\n

You can write data to send in the upper field and start the communication by transmit<\/strong> , and see the received<\/strong> chars in the lower field. You can also transmit the content of the Text editor.<\/strong><\/p>\n\t
