Inno3Pro / I2C : Read back PI_COMMAND registers, Read back multiple telemetry registers
i have two questions regarding I2C communication with Inno3Pro.
1. ) Read back PI_COMMAND registers
It tried to readback PI_COMMAND registers (e.g. 0x10 - CV) without success so far.
Datasheet and innoswitch3-pro-mcu-library only cover readback of telemetry registers (READ10-READ15). There is no example with an I2C transmission diagram for reading back PI_COMMAND registers, although the registers are marked as W/R-Byte or W/R-Word respectively.
Is there a I2C transmission diagram for these, or is it not possible to read them back?
2.) Read back multiple telemetry registers
Reading back telemetry registers allows me to set a start and end register address in the write part of the transmission. How does the read part look like if start and end address differs. Do I just have to read back the number of registers times 2 bytes in one chunk with 2 bytes for each register?
@ 1.) Read back PI_COMMAND registers
just recognized that most (if not all) registers and flags are mirrored into the telemetry data area.
So this question also disolves in thin air.
