| 8051 ISP Programmer | Simple ISP programmer that only needs a simple cable connecting the PCs LPT port to the board. It can program Intel HEX files. Tested only with AT89S51 and AT89S52. With source code, but program messages in Brazilian Portuguese, easy to understand/transla | |
| 89C450 ISP using Python | Python code to download a intel format file to a 89C450 via a serial link and very few hardware (check manual of 89C450). Tested on Linux and XP. Use as "python dwl.py filename". | |
| Linux terminal for NMIY-0031 series 8051 | The NMI 8051 development boards use a monitor program that expects the user terminal to wait for it to echo a character before it sends the next one. Most terminals don't do this so I wrote this tcl/tk terminal script which does. | |
| Simple interface to Kanda SBC | Tcl/Tk app to program Philips 8052 chips using ISP | |
| tcl/tk ISP application for 89V51RX2 | This ISP programmer connects via serial port to the 89V51 chip that i have on my ibot board ( robotics control board ) supports 8051 phillips chips like P89V51RD2FN. | |
