Hello Andy, For disabling the stepgens in config string, I think the value of "num_stepgens" be changed :Does this is all I need to do for disabling stepgens ? num_stepgens [optional, default: -1]Only enable the first N stepgens. If N is -1, all stepgens are enabled. If N is 0, no stepgens are enabled. If N is greater than the number of stepgens available in the firmware, the board will fail to register.
And I saw some option of sserial_port_N: Should I need to change something in this as well ? See below: sserial_port_N (N = 0 .. 3) [optional, default: 00000000 for all ports]Up to 32 Smart Serial devices can be connected to a Mesa Anything IO board depending on the firmware used and the number of physical connections on the board. These are arranged in 1-4 ports of 1 to 8 channels. Some Smart Serial (SSLBP) cards offer more than one load-time configuration, for example all inputs, or all outputs, or offering additional analogue input on some digital pins. To set the modes for port 0 use, for example sserial_port_0=0120xxxx A ’0’in the string sets the corresponding port to mode 0, 1 to mode 1, and so on up to mode 9. An "x" in any position disables that channel and makes the corresponding FPGA pins available as GPIO. The string can be up to 8 characters long, and if it defines more modes than there are channels on the port then the extras are ignored. Channel numbering is left to right so the example above would set sserial device 0.0 to mode 0, 0.2 to mode2 and disable channels 0.4 onwards. The sserial driver will auto-detect connected devices, no further configuration should be needed. Unconnected channels will default to GPIO, but the pin values will vary semi-randomly during boot when card-detection runs, to it is best to actively disable any channel that is to be used for GPIO.

Flashing a different firmware is not a modification, and it entirely reversible. But first you should try disabling the last stepgen in the configuration string and using software PWM on the associated pin. This will need you to add the write_gpio function to the fast thread, as suggested by Seb. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
