3. We haven’t found the firmware for the MCU on Control Unit. Could you please tell me where I can download this firmware?
thanks.
The firmware is now up on github at https://github.com/BUNPC/ninjaNIRS21 .
I'll push to get some documentation up there. Please post any questions you have in this forum.
1. These connectors are not used in NinjaNIRS2020. In previous versions they were used to connect optodes to the control unit without using the breakout boards. See attached picture for the mating PCB with solder pads for the optode cable.
2. There is a programming adapter PCB to allow uploading the firmware to the optode via JTAG. We will add documentation for this shortly.
3. The firmware is on the website in the "Accelerometer" section under "Arduino firmware for control unit". Note it is a very simple firmware only to read out the accelerometer and send the data to the main FPGA.
@bernhard-zimmermann Thanks for the explanations. We have another question related to the 9-axis sensors (IMU, BMI160) in each source-detector module. Would it be sufficient to use 1 IMU for all modules or it is necessary to equip each module with an IMU?
I think it turns out that we never used those IMUs in the source-detector modules. Bernhard probably never wrote the firmware for it. We moved on to NinjaNIRS21 with source only optodes and detector only optodes and we made a separate module for the IMU. Bernhard and Joe O'Brien are working to get the NinjaNIRS21 documentation online on this website.
@dboas Thanks for the explanation. We got another question related to the FPGA in each of the source-detector module. But we did not find the firmware of it. Is the FPGA for source and detector optodes, for the IMU, or for other purposes? If it is for the optodes, where can we find the firmware?
@dboas For the NinjaNIRS21, is the FPGA of the control unit is the same as the one used in NinjaNIRS20?
The firmware is now up on github at https://github.com/BUNPC/ninjaNIRS21 .
As we said above, this is the firmware for ninjaNIRS21.
