FEASA LED ANALYSER
ICT VERSION
Synchronous Serial Mode
Step-by Step Sequence to Read xy & Intensity (xyi)
Initialize the board
- Set Addr0/LA_Select = 0
- Set Clock_in = 0
- Set Data_in to 0
2.
Clear the Comms Buffer
- Set Data_In to 1
- Set Clock_in to 1 and 0 [8] times to clock in each bit
3.
Send the command to read xy & Intensity as follows
- Set Data_In to 0X50 (01010000)
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
4.
Send Fiber Number to Read
- Send (0x01 to 0x14) (1-20 decimal)
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
5.
Read back 7 bytes of data
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
x
high byte]
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
x
low byte]
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
y
high byte]
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
y
low byte]
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
Intensity
high byte]
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
Intensity
middle byte]
- Set Clock_in to 1 and 0 repeat [8] times to clock out each bit
- Data_Out = [
Intensity
low byte]
