The Quality is really first rate. I am waiting on a C Compiler to come in. My business is booming and I have little time to try out new things too often.

Q:
I just bought one of these from you yesterday:and I have been reading up on the DS89C450, so my question is since it is rated as capable of 33 MHz, if I were to change out the crystal would the board still work correctly @33 MHz or a little less?
Asked by:

- 10/26/2013
A:
I would not do that because the thermal effect of such high freq. Also such a high freq might not be compatible with the 9600 baud rate needed for downloading the program into the chip.

A:
Not sure what Administrator means by "thermal effect".
Daniel- You should have no problem with running a different xtal, up to 50MHz I beleive the part is spec'd for. The serial loading program uses an auto-baudrate detect, so it incorrect to say it must use 9600 baud for programming. If this is similar to Atmels serial loading, the software sends an upper case "U" to the micro (55h or alternating 1s/0s); the micro detects the baudrate from these 10 clock pulses (including start/stop bits) sets its internal baudrate generator to the same speed and replies with "U". Baud rate for your application would of course depend on the settings of the SFRs and timers or baudrate generator you choose to implement.

Q:
Can the 8051 be programmed wirelessly?
Asked by:
tony stewart
- 10/15/2013
A:
The training board can be programmed by RS232. If you can add an xbee, bluetooth or another 2 way radio transmission that can convert at the end to RS232, then the board can be wirelessly programmed. As shipped, the board requires an RS232 interface.
