I've discussed to a friend of mine that is familiar with 89C51, and he told me that according to the Atmel's datasheet of serial programming of the 89S51 chip, it's actually technically possible to program the chip with Arduino or Raspberry Pi, but he's not sure if it's doable with USB to TTL(UART) converter. I've searched on the internet about how to program the chip, but most of the information and circuit diagram involves serial RS-232 port, or parallel printer port, or some other expensive commercial programmer products.Īs I don't have a RS-232 or printer port on my computer, I can't follow these diagrams or tutorials. I have a USB to TTL (UART) converter (using the PL2303HX chip), an Arduino Uno board, and a Raspberry Pi board. I am new to microcontrollers, especially the MCS-51 series, but I've heard that MCS-51 is the "right way" to do microcontroller stuff, and I would like to try about learning it. Recently, a have a chance to get a AT89S52 chip, but I do not have a suitable programmer for it.
