ECANxSelectTxBuffers

ECANxFilterDisable

Prototype

sub function ECANxSelectTxBuffers(dim txselect as word) as word

Description The function designates the ECAN module’s transmit buffers.
Parameters -

txselect

: transmit buffer select. By setting bits in the txselect lower byte corresponding buffers are

enabled for transmition. The ECAN module supports up to 8 transmit buffers. Also, by clearing bits in

the txselect lower byte corresponding buffers are enabled for reception.

Returns

- if input parameter is valid

0xFFFF

- if input parameter is invalid

Requires

The ECAN routines are supported only by MCUs with the ECAN module.

Microcontroller must be connected to ECAN transceiver which is connected to the ECAN bus.

The ECAN module must be initialized. See the ECANxInitialize routine.

Example

‘ Buffers 0 and 2 are enabled for transmition:

ECAN1SelectTxBuffers(0x0005)

Notes

- ECAN library routine require you to specify the module you want to use. To select the desired ECAN

module, simply change the letter

x in the routine prototype for a number from 1 to 2.

- Number of ECAN modules per MCU differs from chip to chip. Please, read the appropriate datasheet

before utilizing this library.

Prototype

sub procedure ECANxFilterDisable(dim fltdis as word)

Description The function disables receive filters.
Parameters -

fltdis

: filter disable selection parameter. Each bit corresponds to appropriate filter. By setting bit the

corresponding filter is to be disabled.
