Hi John, Just bare-metal program it then with GCC. You can use the onboard boot loader to program it. If you want to connect a debugger you will have to hack out the SWD JTAG lines. Peter Homann - (from my mobile) http://www.homanndesigns.com > On 9 Jun 2020, at 12:31 pm, Chris Albertson w

THose parts, even the $2.80 development board are gross overkill for an ELS system. They have hardware quadrature counting up to a few MHz. and an available real-time OS if you want.real One compromise that I think really is worth making is to look at JLPSB's short list is "basic" components. T

My TI Delfino F28379D Launchpad kit just arrived. This has dual processors, dual floating point units, QEI modules, CAN bus and a fair amount of memory. And around $40 with shipping. There's lots of support for using these as AC Servo motor controllers but I'm still looking at ELS replacement

No, I had not seen this one. I like the shape of the case I might use parts of the case profile. This looks like it might fit the hand well. He also had a great idea to design the case so that it can be mirrored for left or right-handed use. The 20 characters wide display would not fit but the
