Does anyone know of a sample code to get an RCM4300 talking to an LCD2S?
I’m looking for the basic amount of code to be able to send some strings to the 20x4 LCD display.
Thanks
did you ever find a sample program to do this?
One thing I didn’t realize about the “serial” display I bought was that it only had SPI and I2C interface, no standard RS232 async spec. I went ahead and bought a true RS232 board from Siliconcraft with the same 4x20 display. In trying the SPI interface I ran into too much trouble trying to program the proper signals to the proper pins from the RCM4300 to even send commands to the SPI.
With a standard RS232 async port it is easy to send the proper hex commands with a SerCputc(0x??); for commands and serCputs(“???”); for text strings.
My application actually needs to read hex data from one serial port, parse it and convert it to decimal values for display on another port. This is what I’m working on right now.
