Hello Darryl

Thank you for that. It now looks fine.

I did try reversing the bytes but didn't think about reversing the result, so I guess I was about halfway to solving it.

You have saved me...

Hello

I'm using Darrel's CRC routine to calculate a CRC but the results are not as expected.

Here is Darrel's routine -


CRC VAR WORD
CRC_IN VAR BYTE
Idx VAR BYTE

I don't know much about this device but if you disconnect the i2c data or clock connections, the output latches will contain the values from where the communication stops. Without seeing the program...

Thanks for that Darrel

Unfortunately this gives me the same result as previous. This works ok but it is only in steps of 8. Typical values from the adc are 288,280,272 etc. This means my actual...

I'm using the TSOT package which has a fixed slave address. The ADDR pin is used as an alert on this one.

I think using an address of A3 should work on my device but it doesn't. I get a response...

I am having problems reading a ADC121C021 12 bit ADC with PBP.

From the data sheet it appears that the slave address is 54h and the conversion result register is 0h.

However, when I use the...

Problem solved

lcdout $FE, $80, $B0, $C0

Displays the character B0C0h on the first character position on the display.

I forgot the $80 the first time so you actually helped anyway Melanie.

Thanks but I can already display the ascii characters.

This particular controller has a simplified chinese character set that can be accessed between A1A0h and F7FFh.

Hello

I'm trying to use the LM3037 LCD display which has a ST7920 controller. This seems to be much the same as the HD44780.

I can display the normal ascii character set using LCDOUT but I need...
