Today came in a new batch of PCBs from DirtyPCB.com, of which one is a new revision of the BlackMagicProbe. This revision is almost the same except it has a polyfuse in its powersupply to the target, a dedicated voltage regulator instead of P-FET, its programming...read more
Recently I got a voucher to try Seeed PCB manufacturing, and decided to compare them to my regular PCB manufacturer DirtyPCBs.com. It is always nice to have an alternative to an existing supplier. At first glance they look very similar but some (small) differences...read more
When you get started on ARM microcontrollers things are very overwhelming at first... After coping with the first few hurdles like installing a toolchain and IDE, the next part should be getting a tool to program the chip. Many vendors have some kind of bootloader...read more
