T89C51 Development Board – Tips

If none of the above help, you might want to post the schematic of the setup you are using. Dec 248: In Flip, the RS setup utility has to be run each time the microcontroller is reset into bootloader mode, before the chip is programmed, or it will give the timeout error.

Check for proper reset circuit too. Dec 242: ModelSim – How to force a struct type written in SystemVerilog? To run the program after it is loaded, PSEN is floating or high at reset.


The correct com port needs to be selected in RS setup. What is the function of TR1 in this circuit 3. Distorted Sine output from Transformer 8. PNP transistor not working 2. Hierarchical block is unconnected 3.

Last edited by FenTrac; 24th December at So what i have to do? Losses in inductor of a boost converter 9. But press only when the post helped you Of course, the right device has to have been selected under the device tab. The bootloader requires that PSEN is held low at ratasheet to enter programming mode.

Heat sinks, Part 2: Turn on power triac – proposed circuit analysis 0.

Choosing IC with EN signal 2. I can also do RS Communication and my program can send data and i can receive that data on hyperterminal I am at899c51rc2 RS Connection If yes then how can u programming this IC?

Synthesized tuning, Part 2: PV charger battery circuit 4. The EA pin should have a pullup resistor say 10kto 5 volts.

In the RS setup, the maximum baud rate I can use isso lower baud rates can be tried datashwet see what works. Equating complex number interms of the other 6.



The PSEN pin needs to be grounded at reset to enter bootloader mode. I got error “Timeout” Input port and input output port declaration in top module 2. That also creates this kind of errors.
