Where could it get the firmware for the Microchip PIC 18F2550 microcontroller.

i did not get 60 percent o what you said in the first post ut that is frikkkiinn awesome
Hello
Where could it get the firmware for the Microchip PIC 18F2550 microcontroller.

I am sorry lordin but the firmware is proprietary information and can not be distributed.Originally Posted by lordin
Hey Alok...have you been in touch with the writers about making a plugin for the new CF3?
Hi Alok
need a small help here with tpms..
I am using Robbys Skin and have only modified to 5 tires ( instead of 4 )
All works out fine but for the Aural warnings...
I am not able to get the audio warnings for the press or temp...
I01,219,80,40,71,"TMS_ALERT_FL:B"
I02,381,79,39,72,"TMS_ALERT_FR:B"
I03,216,346,40,76,"TMS_ALERT_RL:B"
I04,385,345,38,74,"TMS_ALERT_RR:B"
I05,644,28,138,161,"TMS_ALERT"
I06,693,513,28,18,"TMS_SILENT:B" ( DO I HAVE TO REMOVE THIS LINE )
I07,288,408,68,71,"TMS_ALERT_ST:B"
B01,630,507,97,86,"TMS_SILENT","" ( Or DO I HAVE TO REMOVE THIS LINE or both )
B02,727,507,67,86,"EXIT",""
if i do it like this /B01,630,507,97,86,"TMS_SILENT","" the red indiacator doesnt work any more and still there is no audio warning..
ive tried all 3 combinations but still i get no AUDIO warnings..
The music keeps playing.. ( so it means the vol is ok and not mute )
Can you pls help from here
Thanks

what u on about noob
anyway, does the dark haired one have a name, much prefered to the blond.
omg i'm sinking.......

This is what we have discoverer so far:
Raw Data Buffer
Byte 0: Pressure Byte (Bar)
Scaling = 0.025 Bar/LSB
Zero Point = 0x28
Formula:
P = (PB - 40)*0.025
Samples:
0x26 = -0.05 Bar
0x27 = -0.025 = -0.03 Bar
0x28 = 0.00 Bar
0x6D = 1.725 = 1.73 Bar
0x7B = 2.075 = 2.08 Bar
Byte 1: Temperature Byte (Celsius)
Scaling = 1 C/LSB
Zero Point = 0x28
Formula:
T = TB -40
Samples:
0x2D = 5 C
0x2E = 6 C
0x3E = 22 C
0x40 = 24 C
Byte 2: Battery Level Byte
Relative level of battery. I think the range is from 0x00… 0xFE.
For the manipulation of this byte to actual “V” I need to know lowest battery voltage on which the sensor could work and type of the battery.
Byte 3: Sensor Mode Byte
It sounds like this byte represents status of the sensors, as per below table (Sensor Modes).
NormalMode = 0x01
Sensor Modes
http://www.mp3car.com/vbulletin/port...erface-19.html
Mode Description
Storage Mode
If the pressure is below 1.5 bar, pressure is measured every 60 seconds but no data is sent. If the pressure increases above 1.5 bars, the sensor shifts into the Initial mode.
Initial Mode This mode occurs if the pressure increases above 1.5 bar from Storage mode. In this mode, pressure is measured every 0.85 seconds and data is sent every 0.85 seconds. This sequence is repeated 256 times. After the sequence is repeated 256 times, the sensor shifts into the Normal mode only if pressure is above 1.5 bar. If the pressure is below 1.5 bar, the sensor will shift into the Storage mode.
Normal Mode
Pressure is measured every 3.4 seconds and data is transmitted every 60 seconds. If the measured pressure differs by more than 200 mbar from the reference taken every 60 seconds, the sensor enters a Pressure Alert mode.
Pressure Alert
It is the same measurement and transmitting pattern as the Initial mode.
High Temp Alert
If the temperature exceeds 120°C, the sensor device enters into the same measurement and transmitting pattern as the Initial mode.
------------------------------------------------
HID Protocol
To poll a sensor data:
1. Host writes one byte to device with required sensor number coded as 0x20 + SensorIndex. First Sensor index equals to 1.
2. Host reads the four bytes buffer from device. Structure of buffer is explained above.
Please help me to fill the gaps and misunderstandings.
Thanks
I'm hoping someone Robby or Lok or Dejan still has the PIC chips by them self for sale?
