Hey! I have an MCU R8C/15 R5F21154, and I am faced with a problem, I do not know what program can be used to write via UART to my MCU? I have looked at a lot of information on the Internet, but I haven’t found what I need. The FDT program has this MCU, but it only works with E8A, and I don't have it, I need to write and read through the UART, thanks.

ちょっとぐぐると自前で書き込みソフト作られてる人もいるし参考になるのでは

↑を見るとFDTは動作保証の関係でE8aを推奨としてるものの他の装置でも動く場合もあるのでは?

↑のライターはFDTが付属しておりUSBシリアル変換はありがちなFTDIのチップで行う構成のようです。
