3.2 3.9 Test on CAN

If the user want to connect the CAN device, please use the CAN8200。

The steps for the CAN connection:

1. The steps for setting:

Set the CAN baud rate as 125 k/bits, and enable the CAN devices.

[root@OMAP3EVM bin]# /usr/bin/ip link set can0 type can bitrate 125000 triple-sampling on

[root@OMAP3EVM bin]# /usr/bin/ip link set can0 up

ti_hecc ti_hecc.1: setting CANBTC=0xc00a8

2. Send the data:

Input the following commands for send data as " 1122334455667788".

[root@OMAP3EVM bin]# /usr/bin/cansend can0 111#1122334455667788

3. Receive the data:

Input the following commands for receive the data:

[root@OMAP3EVM bin]# /usr/bin/candump can0

Receive the data that your send:

can0 80 [8] 01 02 03 04 05 06 07 08

3.2 3.10 Test on ADC

The user can input the analog voltage for PIN1~8 (/dev/adc7 ~ /dev/adc0) on connector J5, the

input analog voltage rate is 0v ~ 3.3v, for the 12 bit AD conversion, the system will display the

digit voltage.

Input the following commands to check the PIN1 analog voltage:

[root@OMAP3EVM /]# adc_test -d /dev/adc7

The channel: /dev/adc0 0x0fff data: 3.2990 V

If it is the pin2, the commands is "adc_test -d /dev/adc6". When the pins is empty,

the digit voltage is 2.2V.

3.2 3.11 Test on SD card

1. Connect to the SD card to the SOC8200 board, if the appear the following information on the

debug port, the SD card had detected.

mmc0: new high speed SD card at address 0001

mmcblk0: mmc0:0001 APPSD 1.85 GiB

mmcblk0: p1

2. Input the following commands to mount the SD card.

[root@OMAP3EVM /]# mount -t vfat /dev/mmcblk0p1 /mnt

[root@OMAP3EVM /]# ls /mnt
