Missing insput param on Twi_Read?

#1 Post by vladaepro » 30 May 2008 11:01

Hi

I need to use Twi_Read function with acknowledge (for sequential read from eeprom 24cxxx), but compiler doesn't accept any params in that function. In help files, there are one input params - acknowledge on/off (tmp := Twi_Read(0);).

Is it a bug?

Thanx

Hi,

this is the help error, we apologize.

Twi_Read prototype is:

Code: Select all

function Twi_Read: byte;

Thanx for reply

I understood it's a help error, but it's very logical to have param for ack in that function. As i said, you can't read sequential from TWI devices if don't send ACK on TWI_Read.

Ok, i fixed it with directly set/reset twea bit:
TWCR.TWEA := 1;
while TWCR and (1 shl TWINT) = 0 do nop;
data := TWDR;

Hope it will be implemented in next build of library...
