I am new to programming microcontrollers, Freescale, and I can not build a program
that transmits data to the computer via an RS232 port.
I'm using a MC9RS08KA8, please someone help me
I found the attached CW project, applicable to the MC9S08QG8 demo board. The code is capable of testing the various peripheral modules, and communicates to a computer using the SCI module.
Hello, and welcome to the forum.
Unfortunately, the 'RS08KA8 does not contain a SCI module, the hardware that will support serial communications. While it is possible to simulate SCI operation in firmware, this is a more complex process, and the timiing is critical.
If you have little previous experience with microcontroller programming, I might suggest that you consider using an alternative device that contains a SCI module. Additionally, the use of the RS08 family will add further programming complication, because of some limitations of this "scaled down" family.
I might suggest that you choose to experiment initially with an evaluation board from the '9S08 family. Most of these devices provide a SCI module. Depending on your ultimate requirements, the '9S08QG8 might be a reasonable choice.
I am grateful for the attention.
Indeed I have very little experience in programming and thanks for the advice.
Seizing the opportunity, I wonder if you have any examples for HCS08 or GQ I take a look.
Thanks in advance.
Thank you very MAC.
