R u using any programmer or using ISP?

Part and Inventory Search. 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.

The time now is How reliable is it? The timeout error can datashewt communication is not established with the microcontroller in bootloader mode. If yes then how can u programming this IC?


If none of the above help, you might want to post the schematic of the setup you are using. To run the program after it is loaded, PSEN is floating or high at reset.

So what i have to do? I can also do RS Communication and my program can send data and i can receive that data on hyperterminal Last edited by FenTrac; 24th December at CMOS Technology file 1.

Turn on power triac – proposed circuit analysis 0. How do you get an MCU design to market quickly? Distorted Sine output from Transformer 8. Dec 248: Digital multimeter appears to have measured voltages lower than expected. That also creates this kind of errors.

The EA pin should have a pullup resistor say 10kto 5 volts. PV charger battery circuit 4. AF modulator in Transmitter what is the A? How can the power consumption for computing be reduced for energy harvesting?


The bootloader requires that PSEN is held low at reset to enter programming mode. Dec 242: Check for proper reset circuit too.
