Re: Gen 3 Prius Transaxle P410 Makes Clunky Noise.

Did today's testing unequivocally show that the inverter temperature is signed 8 bit?

If so then the GS450 tmphs/temp_inv_water still needs fixing

temp_inv_water=int8_t(mth_data[42]);

the part you have missed is it also comes with a 50% increase in size and weight. Tom's data above shows it's possible to get the same or better performance with 2P configuration.

Re: I just bought a Mitsubishi Outlander charger. - Now What?

That's the rear inverter to motor cable.
That price is very cheap for both cables. Was this listing for just one of the cables and did you get the right one?

Re: Setting Up CAN reader - STM32 Nucleo board

You can not just change board type and expect it to compile . The STM32 core library does not support can so an external library is needed, ( or write your own ). Even then a lot of changes are needed to get it to work.

Non of the libraries I am familar with support STM32F334.

Re: ISA Shunt With ZombieVerter VCU [FINISHED]

The SPI connections are on the connector marked "SPI", just look up Arduino Due pinout for actual pins.

If you intend to run Savvycan then you only need one or two CAN transceivers, either a MCP2551 or SN65HVD230.
CANRX - CAN0 RX, CANTX - CAN0 TX.
DAC2 - CAN1 RX, Pin 53 - CAN1 TX.

They are load capacitor for X2 which is a crystal for the real time clock. As this uses an internally generated clock the crystal is not fitted and the capacitors are not needed.

I think this is the correct part Sumitomo 8100-3455. I buy parts from here https://www.auto-click.co.uk/6189-1240
Not so good from outside the UK but is a least a good source of infomation.

Re: Webasto HVH50

If I use the max 8 bit value of 255, by the formula of (255-256)*40 = -40, right??? No, the simplist way it to put the code back to how it was originally with the power sent over LIN the required power / 40. The 400 - 256 is just truncating a 9 bit number to 8 bits, it's not a general formula for c...

Good to see that you are getting heat but I think you are looking at the status ID data rather than the measurement ID. From your update in the wiki this seemed a posibility and checking back in some of the previous data there was also a response on ID 23. Maybe check if ID 23 is Read Meas and 39 is...

Re: what am I doing wrong ??? ESP32 flashing

It might be the mismatch in stop bits between the stm32 terminal and the ESP32. I've only used the ESP8266 with uart but had to modify the stop bits to 2 for the initial 115200 baud rate.

Looking forward to the next video were we get to see the charger right side up! The connector is also used on the GS450H transmission ( ECT solenoid ) Toyota 90980-12326 . The wiki page pin out table is a bit confusing as the pin numbers from the schematic do not match the numbers on the connector. ...

The scaling is for the value sent/received over linbus. Just set the temperature and power that you require. Power is in step...
