To follow up on last week’s upload articles, I’m going to turn a couple of these boards into Black Magic Probe programmers:
From left to right: an STM Nucleo F103RB (any Nucleo will do, though), a board from eBay (many vendors, search for “STM32F103C8T6 board”), and Haoyu’s HY-TinySTM103T.
And let’s do it right, with a couple of custom PCB’s – here are three versions (the first one will keep its original firmware, actually). Each does have slightly different usage properties:
- Use any STM Nucleo as programmer – Wed
- From eBay “C8” µC to BMP tool – Thu
- The HY-Tiny can also act as BMP – Fri
Each of these supports uploading, serial “pass-through” connection, and h/w debugging. Building one of these, or getting a pre-built & pre-loaded one, is a really good investment.
