Yes, but it's probably specific to a manufacturer and/or model. You measure the rotational speed of the output axis of the gearbox. How those rpm translate into a given speed depends on the car wheel size.
Depending on the car you could also get the speed by reading the ECU through the OBDII port.
I once made an rpm meter. I remember counting the pulses within a given time period, like half a second was much easier and yield higher resolution than measuring the time between pulses. On the other hand counting the pulses in a given period gives you a much smaller refresh rate than measuring...
Are you working in C language or assembler? or something else?
In C it looks quite simple:
if (((BCD_Hours * 60) + (BCD_Minutes)) == ((EEPROM_Minutes_High << 8) + EEPROM_Minutes_Low))
While someone can know exactly how to solve this error, most of us will need some more context. It seems that you are feeding the function a data type that it's not expecting.
Which line of code is generating the error? You should check on the prototype of the function which data type it uses.
If you need Modbus Master I asume there is a slave nearby that you need to connect to. In that case, modbus devices sometimes come with a lengthy manual describing the protocol. There should be something, since you need to know what's on every register to understand the information. You should...
That would allow us to keep most of the dynamic C code at least. Its an option. I guess we'll have to put options into costs and see what they decide. Thanks
Yes, the price is not that high, but I feel a 10 dollar PIC32 and a few peripherals would be enough to replace the Rabbit module. I appreciate you feedback on the matter, I think you are right about the module not going away any time soon. Regards
Hello everybody, I'm a long time reader of this forum but I never had the chance or the need to post before. Thanks for all this years of knowledge. Here's my issue:
I'm working with a customer on upgrading the industrial equipment they manufacture. They have a main terminal based on a RCM3000...
