Hi Peter; My 6040 gantry mill has I think, a 2x7i76 firmware in its 5i25, with a 7i76D on the 5i25's p3, and an ATM a std Sainsmart bob connected to p2. The current config string for the 5i25 has 4 stepgens, no encoders, and no pwmgen. An readhmid shows identical setups for both p3 and p2.
Trying to figure out how to get a single signal out of the 5i25 to pulse the power to one of these teeny peristaltic pumps in the form of a pwmgen to pulse it, at variable pulse widths and there by control its delivery. Can I enable a pwmgen in the 5i25 config, getting its output from the bob on p2, in which case what terminal on the bob will be the pulse output? There is not a load on the bob attached to p2 at the present time, and a grep of the .hal file only returns the addf's for gpio.read and gpio.write. No gpio in actual use (yet...) Enabling one pwmgen shows it on 5 and 6 of p3 in the dmesg list. Is that the stepgen-4 on the 7i76? In which case that could work. It turns out I have to enable pwmgens=2 in order to get to the p2 connector at [1501700.940971] hm2/hm2_5i25.0: IO Pin 025 (P2-05): PWMGen #1, pin Out1 (Dir or Down) (Output) [1501700.940980] hm2/hm2_5i25.0: IO Pin 026 (P2-06): PWMGen #1, pin Out0 (PWM or Up) (Output) What should I do?
