# people-seven
People Counter - Receiver Node
Program receives values over i2c and displays in an array of
6 x seven segment displays
Programmed to run on Teensy 3.2
### TODO
```
- Receive value over serial / i2c https://www.pjrc.com/teensy/td_libs_Wire.html
-- Read values from custom header
- Implement timers
-- display duty cycle (fade)
-- update display
-- stream values
- Add hardware listing to README
- Add file header
- Extend Symbol Encoding for alphanumeric
-- Simplified serial receiver should handle char
```
### Implemented
```
- Serial for debug and comm
- Create lookup table for numeric characters
- Write simple values to displays
-- Use PORT instead of digitalWrite
```
### EXTEND
```
- Real values
- Different display modes
- Write ID to EEPROM? https://www.pjrc.com/teensy/td_libs_EEPROM.html
- i2c dynamic address
-- ("does anyone have address a, no reply to assign address")

-- https://github.com/PaulStoffregen/Wire/blob/master/examples/Scanner/Scanner.ino
-- https://forum.arduino.cc/index.php?topic=37304.0
- Extend lookup table for alphanumeric characters
- Extend display for spatial applications
- Fade with Shift PWM
-- Write faster shiftOut
-- Display is class?
- Debug Mode
```
### COMMS - HEADER DESCRIPTION
```
- 0x3F. Protocol check '?'
- 1. Datatype description
-- 0x00. Write new value (bin)
-- 0x01. Write new value (char)
-- 0x02. Set Brightness
-- 0x03. Reboot
-- 0x04. Change Mode
- 2. Do acknowledge
-- 0x00 no ACK
-- 0x00 ACK
- 4. Data byte 1 | Value (Brightness)
- n. Data byte n
- \r. End with CR
```
### SCREEN MODES
```
- 0x00. Display array
- 0x01. Display All
- 0x02. Display None
- 0x04. DEBUG
```
