Help is needed for the Spindle encoder.
I have a Lathe setup running with X-Z axis.
Spindle working for commanded speed.
The shared home switch also working.
But I have phase-A on pin 8.
Index on pin 10.
in hal show nothing to show for encoder related.
Please look at my spindle.hal for modifications.

Small progress, now phase A working. but hal hal show encode.0.velocity do not match with commanded S300 M03 in MDI.
Tried to run G76.ngc do not run.

[code]I hope to get some guidance on the issue regarding the ARISC driver.
I am currently adapting a new development board, which is similar to the Raspberry Pi and Orange Pi. I am not quite sure how to configure some of the settings in the `api.h` file. Where should I obtain these configuration details from in the chip's manual?
[code][code][code]#ifndef _API_H
#define _API_H
...
#define ARISC_CPU_FREQ 450000000 // Hz
#define ARISC_FW_BASE (0x00040000) // for ARM CPU it's 0x00040000
#define ARISC_FW_SIZE ((8+8+32)*1024)
#define ARISC_SHM_SIZE (4096)
#define ARISC_SHM_BASE (ARISC_FW_BASE + ARISC_FW_SIZE - ARISC_SHM_SIZE)
#define GPIO_BASE 0x01c20800
#define GPIO_R_BASE 0x01f02c00
#define GPIO_BANK_SIZE 0x24
#define GPIO_PORTS_MAX_CNT 8
#define GPIO_PINS_MAX_CNT 24
#define PWM_CH_MAX_CNT 16
#define PWM_WASTED_TICKS (160/2) // number of ARISC ticks wasted for calculations
...
static inline
void shmem_deinit(void)
{
munmap(_shm_vrt_addr, ARISC_SHM_SIZE);
munmap(_gpio_vrt_addr, 4096);
munmap(_r_gpio_vrt_addr, 4096);
}
#endif
Are there any additional configuration changes needed apart from the ones mentioned above?
Thank you for your help.

Quick question on this.
Is there a way to configure the arisc module to control a cw and ccw pulse rather than step/dir ?
I got it running just fine with step/dir, but i have a rather old and somewhat difficult to change servo/amp that can only be run using cw and ccw pulse mode.
Thanks in advance.

Normally yes, very easy, just change the stepgen_type from 0 to 1 in the hal file for the axis/joint you want.
Or might be 2, not sure, it was a long time ago, but a quick search for stepgen type linuxcnc should get the results.
