... 1.) Wait for start bit 2.) Delay 0.5 bit and sample the bit again to verify that it still is a startbit and not a glitch. If a glitch - go back to 1. 3.)...
Jay, You can program the COPCTL register to enable the COP Watchdog, then to invoke an immediate Reset by writing a data different from $55 and $AA to the...

Hi there, I'm currently experimenting with an Adapt912B32 board, using it to control a couple of motors via PWM. A variable resistor is being used to create a...
Jay, Your step 1 will have problems if there is noise or noise filtering between the transmitter and the receiver. A very narrow pulse to 0 at the instant when...
Yeah, it's a Spice front-end, I think. The schematic entry is better than most CAE tools. The demo seems to last forever (I have an old one) but it is...
... ========================== That would be at 16 times the bit rate. Could maybe do it with a dsp...... they used to do a pretty good 4800 baud bit banger...
Hi i have set one of the pin PTA2 and PTA1 in PORT A on 68HcS12 as input. when i am trying to read that portA I dont see PTA1 and PTA2 being read. I have set...
Kittu, Using the PORTA pins as general purpose I/Os is possible only in Single-Chip modes. In Expanded Modes and Emulation Modes the PORTA pins are used to...

We're using the 9S12DP256C in a product that will hopefully soon go into production. The development cycle has been rather painful thus far - we started with...
Sam, The MC9S12DP256 was the first silicon that Motorola released in the HCS12 - STAR12 family, and as such it has suffered from a large number of initial ...
Hi All, I notice that the group seems to be silent on the use or implementation of the emBetter tcpip stack as per the Alarm Control Panel reference design (or...

Have a look back in November at "start 12 with ethernet interface" I don't think it mentioned Alarm Control Panel. I 'll be interested in your findings incase...
Hello, By the 9S12E128DGV1/D figure 1-4, 9S12E64's RAM size is 4K. By the MC9S12E128FS, It's RAM size seems 8K. And from the test, it seems RAM size is 8K. ...

Namsh, Currently the MC9S12E64 is using the same silicon and mask-set as the MC9S12E128. This is the reason why in practice you see 8K RAM and 128K Flash in...

... Thanks. It's damn thing. Because I need 8K, I added external SRAM and wanted to use next settings. 0x1000 = external paged SRAM (4K page) 0x2000 = non-page...

Hi, Namsh's point is very important. If you have as I am working on to have up to 31K of RAM in near memory were a portion of is internal - thats fine, but if...
