Question 1

In this LIN Transceiver, the RXD pin requires an external pull-up. For LIN, I need 2.2k pull-up on the RXD line for proper operation. If I pull-up the 2.2k to 3.3V, the maximum sink current through ...

Question 2

Is it possible to convert an RS485 signal to TTL and then to LIN without using microcontroller?

Question 3

I'm making a VCO for use as a module in a synth. The oscillator part is working fine. I also need to translate a 1v/oct voltage input to a log scaled voltage output in order to get the correct freq ...

Question 4

I am looking for a can it be done and, if someone is willing, a how to. I am building an OBD2 breakout box for easily scoping automotive computer data lines and want to add LEDs as a quick visual of ...

Question 5

In numerous articles by IC manufacturers and measurement device makers, I've encountered references to LIN PID indicating the expected length of data bytes in the response. ...

Question 6

I am using the UART of an STM32F103C8T6. When selecting the Asynchronous mode via the CubeMX everything works fine using either of the functions ...

Question 7

What is the proper value for FB1 in relation to the surrounding capacitors in this diagram? The FB1 resistance is measured to 0.76ohm and package size is 0603. All components are AEC-Q200 rated. The ...

Question 8

I can see there is 50 mΩ in LIN bus with LIN ICs. But I don't understand why it is there. Does anyone have an idea why I see 50 mΩ in the bus line?

Question 9

I am doing research about some communication protocols: CAN, LIN, I2C, and how they're used mainly in the automotive industry but I'm getting confused as to when each of them are used and if their use ...

Question 10

I use MC9S08DZ96 MCU (NXP). I wrote the corresponding registers to create a break at the beginning of the data LIN frame. The data frame is sent correctly, but the problem is that the break part is ...

Question 11

What would happen if I pull down the INH pin of this IC to GND? I am unable to understand what would happen if I pulled to GND or make it HIGH? Can someone help me ?

Question 12

I've got an older vehicle that is wired for a CD changer. I'm using a few components to trick it into playing Bluetooth. Components MCP2025 Transceiver for car's LIN bus Regulates voltage (>12V ...

Question 13

I understand that how open collector works on protocol like I2C. However, from my understanding, the automotive protocols like CAN and LIN also use open collector to talk to other devices. LIN is ...

Question 14

I'm using the MCP2021A for my project. In this component, there is a voltage regulator but I have no use for it. They usually power microcontroller like the PIC18F2455 but I'm using a Raspberry Pi ...

Question 15

I'm trying to understand what protocol is used on a particular device in order to decode it and send custom values. So far I was able to record the data with a logic analyzer but couldn't figure out ...
