Re: Please Help Me!!(PIC18F47Q10_I2C)

It's Solved. Thank you very much MARTIN. I post programs for others. But there are some problems. Values are well read. However, the values measured and measured with an actual multimeter are different. Using a 10Kohm volume, low voltage was applied to both sides, and the voltage drawn from the midd...

Re: Please Help Me!!(PIC18F47Q10_I2C)

I think I am wrong. So, I modified the program using another MCU (PIC18F26K22) and another ADC (MCP3428).

But the result is not good. The first byte value comes in. However, only the value "255" comes in the second byte.

Pullup = 4.7KOhm

Somebody ask for advice.

Re: Please Help Me!!(PIC18F47Q10_I2C)

With your help, I2C works fine. Thank you.
However, when reading in 16bit, the first byte comes in and the second byte is fixed at 255. I upload my modified program.

Thanks for your help.

Cleared the delay timer. And I looked at the datasheet. But I definitely used CH1. I don't know what's the problem.

Re: Please Help Me!!(PIC18F47Q10_I2C)

I pulled up 4.7Kohm resistors on SDA, SCL.
And when viewed with an oscilloscope, the clock is not generated in SCL.
Heart count monitors MCU operation status. Heart count doesn't make sense here, but it works fine.

Re: PIC18F47Q10 ADC not working

I want to use the touchpad. But it doesn't work. It works well with programs created by others (MPLab X IDE).
However, it does not work in FC8, and only 0 is displayed.

Re: PIC24fj256GA406 RS-485 Based Modbus RTU

I changed the MCU to PIC18F47Q10 and tested it. However, the result is not good. When I used MAX485 and tested it in RS-232 TTL mode, the data is not perfect due to timing problems, but it works well. However, MODBUS RS-485 mode does not work. PIC18F47Q10 has UARTINT0, but UARTINT1 is not visible. S...

However, it is not received from the communication program (Modbus Poll). If set serial TTL instead of Modbus mode, trans...

PIC24FJ256GA406 SPI Channel4 Different

Hello everybody!

I designed to use SPI by referring to the PIC24FJ256GA406 manual. The pin definition of SPI channel4 and FC8 are different in the manual. MISO and MOSI have been changed. My PCB is already made.

Is there any way to solve this?

Thanks for your advice. Share the schematic. As I advised, I knew there were some things I didn't know. I have no experience with FET. So, I want to use the FET Gate driver. Gate Driver wants to use ZXGD3001E6. The power supply voltage is 12V and the control voltage is 3.3V. However, the Vin voltage...
