With Teensy, you don't have to use the Arduino IDE. It is a Cortex M7. There are at least four good, professional-level development environments all the way up the STM's "Cube" A good compromise is ARM's Mbed. It is almost as easy as Arduino but includes a multi-tasking real-time OS with

Re: [Emc-users] Working on Pendant and debouncer PCBs, comments welcome.

Hi Peter, I'm far more interested in the dual processor TMS320F28379D than the ST family. I've already ported my ELS code over to a PIC32 and through a buffer board have a 40 pin ribbon cable plugged in place of the PIC18F. It will be trivial to lay out a board that does this and uses the

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

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.

Re: [Emc-users] AC power for stepper motor drivers?

I 'rebuilt' a smaller lathe and mill, new steppers, drivers etc, but I wanted to keep the knobs/switches on the enclosure working like they used to. So I just ended up doing everything with DC.  I only found out there are drivers that actually use DC (after I upgraded one of them), else I

Re: [Emc-users] AC power for stepper motor drivers?

I just re-discovered Antek. They make toroidal transformers for CNC and high-end audio. They also make unregulated DC power supplies using these transformers. If you need 5.6 amps at about 80 volts DC one of these will work https://www.antekinc.com/ps-5n84-500w-84v-power-supply/ Note that it

Re: [Emc-users] AC power for stepper motor drivers?

I have one that does both,  for a larger stepper motor. It can take a bit of effort to find a DC PSU that can actually provide 5.5A the motor can 'pull', it's a lot easier to get a transformer for one (my driver is 48VAC-80VAC OR 24VDC-110VDC) Jus a transformer will provide the amps your

[Emc-users] AC power for stepper motor drivers?

Some of the larger size Stepper motor drivers will use AC input power. I assume all that is needed is a transformer that is rated for the required current (and a fuse.) Most people are using these Meanwell-style switching power supplies but it seems AC power might be better Questions Is there
