Looking at the wiki I see the base address and offset configuration that allows 4 analogX modules on a single CAN bus.

Skimming through code on github I see

Code: Select all

 // CANFilter shiftx2_can_filter = &#123;1, 0, 1, 0, 0x000E3700, 0x1FFFFF00&#125;; // g_can_base_address, ANALOGX_CAN_FILTER_MASK
.
.
.
offset |= palReadPad&#40;GPIOA, ADR1_ADDRESS_PORT&#41; == PAL_HIGH ? 0x01 &#58; 0x00;
offset |= palReadPad&#40;GPIOA, ADR2_ADDRESS_PORT&#41; == PAL_HIGH ? 0x02 &#58; 0x00;

Are there limitations that would prevent loading a revised firmware to analogX, with different base address or offset, values so that more than 4 modules could be on the same CAN bus?

Hi,

With updated firmware, you can have it listen on any CAN base ID as needed. No limitations.

Thanks Brentp. One step closer to purchasing more than 4.

What tools are needed to compile the revised firmware and load it to analogx?

Hi,

We have updated the documentation here, which will be sufficient for a knowledgeable engineer to program and update the firmware.

If you are looking for a quantity OEM-style purchase, we can be contracted for these services. Just email [email protected] and we can help out.

Thank you,
