• Comparison between ADC inputs and voltage references.
• Register bits of DIDR1.
• LIN Break Delimiter.
Diagnostic frames of LIN 2.x use “classic checksum” calculation. Unfortunately, the setting
of the checksum model is enabled when the HEADER is transmitted/received. Usually, in
LIN 2.x the LIN/UART controller is initialized to process “enhanced checksums” and a
slave task does not know what kind of frame it will work on before checking the ID.
Problem fix / workaround.
This workaround is to be implemented only in case of transmission/reception of diagnostic
frames.
a. Slave task of master node:
b. For slaves nodes, the workaround is in 2 parts:
Before enabling the HEADER, the master must set the appropriate LIN13 bit value in
LINCR register.
– Before enabling the RESPONSE, use the following function:
void
unsigned char
}
temp = LINBTR;
LINCR = 0x00;
LINBTR = (1<<LDISR)|temp;
LINCR
LINDLR = 0x88;
lin_wa_head(void) {
= (1<<LIN13)|(1<<LENA)|(0<<LCMD2)|(0<<LCMD1)|(0<<LCMD0);
temp;
// It is not a RESET !
// If it isn't already done
