Hello guys, its been a long time i was here.
Here is my question: I need to flash program into Nuvoton microcontrollers W78E516D. It's pretty old IC, based on 8052 standart. I need an IC-programmer simple inough to build it myself in couple days. Some schematic and programs will be helpfull.
I can not buy somthing ready-to-go, like ChipProg for example. Local market is poor on this things. But also this week our borders was closed for caranteene, nearest 2-3 weeks nothing gets in and out. Appreciate any suggestiones and help.
P.S. I'm into AVR, STM32 and a little Microchip. But I have no time to design IC programmer specialy for Nuvoton from zero. O, one more thing. My chips are empty, so there is no bootloader on board that I can use.
