Thanks PCM Programmer,

I tried this, along with a few other addresses, and nothing seems to work. I also commented out the I2C stuff and tested the pins as general IO to verify they are actually f ...

Hello,

I'm having some trouble getting a DSPIC33FJ12MC202 to act as an I2C slave (not acknowledging data and not entering the interrupt). The I2C master is a FTDI FT4222 chip where the SCK and SDA ...

Where's the declaration of 'ii' ? Where is 'i' ever initialized to 0 ?

They are both just above the code I copied (i is also=0 above the second code block). ii is uint16.

One possible concer ...

Thanks for the help!

I was using the UART pins for something else on my demo board so I took that device off and connected the OpenLog. I also removed the code which prints to the debug monitor an ...

I'm hoping someone can help me out with an issue I'm having. I purchased an OpenLog module for a process control/data recording project I've been playing around with. I can create files and log, to ...

Ha! Software vs. hardware setup was it! I guess this may be the downside of blindly copying max6675 code off a forum...

The numbers are a bit off but I'll chalk that up for calibration and being ...

Still nothing but I borrowed an o-scope from work. It looks like the CS line is dropping low as it should; however, I'm not getting anything on the CLK and DI lines. Could this be a SPI setup issue? ...

Thanks Ben,

I commented out the recommended line; however, I'm still not reading anything.

Yes, the MAX6675 should be straight-forward...

Updated code:
void init_temp()

Hello,

I'm having trouble getting a MAX6675 to work with my CCS USB demo board. I am continuously reading 0 from the chip. Is there anything obvious in my code? The LCD portion works fine. I ca ...

OK. I was measuring "blink times" using an o-scope and everything looked fine besides the ICD value. I will ignore it for now. On to other issues...

Hello,

I've just started using CCS C after a four year hiatus. The project I'm working on uses a PIC18F2550 to communicate, via USB, to a computer and act as i2c master to communication with two P ...

Based on a previous post I had already changed the "delay_cycles(1)" to "delay_us(1)." This didn't help the problem.

The "as-is" flex LCD driver didn't work but comme ...

PIC connections:
PIC D0 = LCD pin 6
PIC D1 = LCD pin 4
PIC D2 = LCD pin 5
PIC D4 = LCD pin 11
PIC D5 = LCD pin 12
PIC D6 = LCD pin 13
PIC D7 = LCD pin 14

Vdd = 5V for PIC and LCD

I am working on a project where I am trying to connect a Varitronix LCD (digikey P/N 153-1078-ND) to a PIC18F4520. The problem I am having occurs in the LCD.c file at the while(bit_test(lcd_read_byte ...
