FEASA LED ANALYSER
ICT VERSION
Synchronous Serial Mode
Step-by-Step Sequence for LED Analyser Capture for PWM LED's
1.
Initialize the board
- Set Addr0/LA_Select = 0
- Set Clock_in = 0
- Set Data_in to 0
2.
Clear Comms Buffer
- Set Data_In to 1
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
3.
Set Data_in to 0
4.
Set Addr0/LA_Select to 1
- Data_Out goes to 0
- RyBy_bar goes to 0
5.
Wait 1m
6.
Initialize the capture
- Set Data_in to 10101010
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
- Data_out goes to 1
- RyBy_bar goes to 1
7.
Send one capture command from the following list
- (0xB1) PWM Manual Range #1 (Low)
- (0xB2) PWM Manual Range #2 (Medium)
- (0xB3) PWM Manual Range #3 (High)
- (0xB4) PWM Manual Range #4 (Super High)
- (0xB5) PWM Manual Range #5 (Ultra)
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
8.
Send the PWM Averaging Time as follows
- Set Data_in to one value between (0x01 to 0x0F) (Default 0x07)
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
9.
Read back the Capture Acknowledge as follows
- Set Clock_in to 1 and 0 repeat [8] times to clock in each bit
- Read back 8 bits after each falling edge of the clock
- (0xD5 is positive response) (0xEE is an error response)
