Just in case there is still anybody using my S12X/XGATE assembler. The project is now hosted on GitHub. The URL is: http://github.com/hotwolf/HSW12 ...
Hello all, I m very new to micro controllers. I have following micro controller 68HC12 :: MC9S12DG256B I have a GPS module and a Stepper motor. Now i m...
Parallax sells 3 GPS modules, you don't specify which one. The GPS should be connected to the SCI port, not the SPI. The connections should be +5, ground, rx,...
Short answer: If it's the gps module I think it is, you need to connect it to the SCI port, not the SPI. You'll need to connect the SO pin to both the TXD &...
Hello all, ... Thank you very much... I have been on this from 1 day... I have studied the data sheet of Processor.. But as i told you i m new i understand all...
Yes, use gnd, vcc, ttlRX, and ttlTX. Connect ttlRx to PS1 and ttlTX to PS0. You will have to set up DDRS to make PS0 and PS1 into serial port bits. For the...
I have following micro controller 68HC12 :: MC9S12DG256B I have connected my GPS Module to pin PH0. Now please help me communicating with GPS Module via PH0. ...
I have following micro controller ... Ok this is what i have done.. SPI0BR = 0x12C0; SPI0CR1 = 0x54; SPI0CR2 = 0x0; WOMS = 0x0; while (1){ while (!(SPI0SR &...
As far as your code goes, Rather than 0x12c0, use a define ie. The first issue is you should use the SCI port, not the SPI. SCI is an asynchronous (it...
Thanx for your nice and brief explanation to what i have to do. But the thing i m confused is that in case of PSI do i connect SIO pin of GPS to both PH0 and...
His instructions are quite clear. Either you are not reading them or you have to ask your instructor to explain the difference between the SPI and the SCI. ...
Thank you for your kind reply. I m doing this at my own, i have no instructor. I have viewed his reply very carefully and in detail. I know the difference...
I don't have the data sheet for the part but... There will be two pins associated with the SCI interface, TXD (transmit data) and RXD (received data) refer to...
Hi all, I am Grad. student intending to do my course project using 6812. Would you all give me your opinion on following que. 1) Is it possible to port any...
I did a course on using a custom RTOS and the hc12 to control heater/cooling system to control temperature. It was a 4 month course. One month from zero...
Hi , Thanks for your reply. Sorry don't know if I am asking too much but I saw on freeRTOS link that its supports the 6812 machine. http://www.freertos.org/ Do...
I brought up uC-OS/II on a 68332 a while back, it also has ports for the HC12. One month, no way. There is a lot of "stuff" to deal with when bringing up an...
I would recommend that you look at the book: the HCS12/9S12: An Introduction to Software & Hardware Interfacing by Han-Way Huang. This book was a great...
I M USING FOLLOWING MICRO CONTROLLER : MC9S12DG256B (68HC12) I HAVE CONNECTED MY GPS (SIO PIN) TO SCI PORTS (PS0 AND PS1). MY GPS MODULE TAKES FOLLOWING INPUT...

Since I am kind of new to all of this terminology, do you know what section it could be under? I am looking at this 450pg.++ user's guide to the microprocessor...
From the beginning up to the end would be the best. Plus not less important reading, CPU reference manual. If you are not going to use these MCUs seriously,...
