I'm slowly picking away at the updates to the board as issues are found. glink, when you get some free time can you please double check the 113.5mm dimensions? I drew the board up to 113mm across the top and bottom hole spacing but it looks like it might be 115mm. The .5mm difference won't be enoug...

This should be accurate measurements taken with digital caliper. Except the dowels are Ø3.0mm...
All measurements are center to center wrt the holes/dowels

If you need help testing please PM me. I have have a test rig and both the 110KW and 160kW inverters available (although they are probably the same without the Nissan brain)

Thanks, had a look at the code to understand the algorithm, and undrestand now the relationships :-) My problem was that having -25 potnom on the generator side worked fine from 0 RPM and up at given motor side Pot, but not going from 0 potnom to -25 potnom on the generator side wit same Pot on moto...

Hi, tried to wrap my head around the regen setup when testing out on the bench with a "dyno" setup with two em57's against eachother. I want to control the regen with CAN, but I see very different behaviour when regen is controlled by CAN vs when I "set" potnom using offthrotrege...

Hi, the settings here has helped a lot. I have set up a "dyno" rig to try to find out how to configure my setup for my boat using only 48V. I'm using Auris inverter (about the same spec as Prius inverter I guess) and Nissan EM57 motor. The KV of the EM57 is 18.46 according to sources, and ...

I have some recent experience with this and I'm using the boost circutry to boost to 120vdc because I thought I needed it to achieve higer rpm on the Leaf motor, but I'm only able to get 3kw output resulting in about 1000rpm in my setup...asked about this on another thread btw. Have tried boosting t...

Thanks, thought it was the buck-boost hw that might be limiting the amps? Around 60 amps only.

I have a running system in my boat with Toyota Auris Inverter boosting my 48v battery pack voltage into the Leaf em57 motor, but I'm only able to get 3kw out of it. Have tried boosting in the range of 120V to 300V but that does not change real output much. Everything runs smooth and nicely, but expe...

Hmm, maybe I have the resolver wires messed up as well, but thought it was only one permutation that would work

First I assume you've calibrated your potmin and potmax. Second, spinning without throttle usually indicates an incorrect syncofs setting. Have you calibrated that yet? Thanks to both! Haven't calibrated anything, I do the POT adjustment with CAN communication. Potmin=0 Potmax=4095 Throtcur=1 No, I...

I know this has been answered, but not able to find it. Question is how to control the low speed using the FOC firmware? (Using 5.0 now, but same with previous version) With my setup, I'm not able to start my Nissan Leaf motor from the Toyota Gen 3 inverter unless setting POT to 1300 (out of max 409...

Hmm... Reset should happen if the board is built 'properly'. Is there a manual reset you can try? For now, the culprit imho is the FTDI board. Uploaded a sketch with the Atmel ICE, but still no serial I/O. Until I get a new FTDI board I will program using the Atmel ICE, but it's a bit more cumberso...

0xf0 - at least you're getting a response. Is the board resetting properly? And have you tried the 'atmega328p (old bootloader)' option? They changed baud rate a year or two ago... EDIT Also be sure you're using the right COM port, COM4 is suspiciously low. Thanks for having a look, have tried the ...

I think you have the programming cable in the opposite direction, the gnd (black) should be facing the center of the board and not the edge. The silk screen (white text on the board) should read "blk" where the gnd goes. If none of this works, try swapping rx and tx on the programming cab...

Hi, lots of advanced discussions, great! But do we have some descriptions for actually getting the code into the 328p? Nothing here: https://openinverter.org/wiki/Toyota_Prius_Gen3_Board#Atmega328p_Firmware, and I'm having trouble and probably not setting stuff up correctly :-) I think you have the...
