Once hardware issues are solved, I need to be able to program the chip. I have installed Kiel with C51 addon.
I believe this is all I need to write the program.

Following this, how will I write the software onto the chip? What software will I require to do so? Whilst there are some tutorials online, they all provide basic information, not enough for a beginner. I’m hoping that any answers will be detailed enough to assist other beginner people like myself.
Whilst advisable, it is not always necessary to insert resistors here. Doing this removes the need for the HC, opting instead to do it manually. To then use the chip, these three steps need to be undone as they apply only to programming.
Yes, USB to serial Provided it is of the 5v TTL type, as opposed to the conventional rs found in a computers serial port removes the need for the A transciever. This is only required for the computer Serial ports due to datasheet different logic level. Keil C51 is suitable to programming for the chip, although other packages are available.
To flash the chip, the best datashdet to use is the manufacturer supplied MTK which can be downloaded off their website with a bit of searching. Whilst this software is designed for set serial ports and baud rates, custom ones can be used although compatibility is not allways assured.
Home Questions Tags Users Unanswered. If you’re truly a beginner, why start with an obsolete architecture? But I dafasheet you would mention: There are two kinds of “USB to serial”.
I would like this answer even better if it linked directly to the manufacturer’s recommendations for programming — the schematics in the “DS89C Datassheet Kit” documentation k and the “In-System Programming with Based Microcontrollers” application note a.
