I think like this is good for configuration of periodically transmitted PDOs
both on ordinary CAN network and CANopen over Ethercat and possible others.
Pins available for component in hal file come from mapping entries. From 0x1600
to 0x17FF for RPDO mapping parameters. From 0x1A00 to 0x1BFF

I think we're actually all saying about the same thing. A controller like a PC
or a Pi3 needs some sort of external hardware that can deal with high speed
quadrature encoders. Whether it's done with a STM32 or FPGS doesn't really
matter for the sake of discussion. Meanwhile, as Jon

Yes the PRU is unique. This is both good and bad. Bad because using

Not all devices allow changing the PDO Mapping entries. Some of them first
require setting the unit into a programming mode. Then you write to those
locations. Then send a save command. On power up the device fills them in
itself. You need to use SDOs to change those locations so you will

What market share gives a product familty is suport for a while eco

Hi Chris,
Way back the MC6805 was listed as having the most market share. I'm not sure
whether the STM32 has the most or if it's really just the ARM architecture.
Numbers like that always get thrown around to appeal to the "Join the Popular
