Micro ECU with PIC programmer

The MicroECU contains a PIC18F24K50, fitted with microUSB socket and an internal bootloader for reprogramming.

Programming software is available from the Matrix web site.

The connections are:

A - A1
B - C2
C - A0
D - C1
UP - C0
DOWN - C6
RESET - MCLR
OK - C7
LED - A5
LCD SDA - B3
LCD SCL - B1
LCD A0 - B2
LCD Reset - B4
LCD CSB - B5

The LCD is a HZYO12832E.

The supply voltage is 5 - 12V. The MicroECU can be powered from the +V and 0 pins or from the MicroUSB socket.
Each of terminals A, B, C and D is fitted with series 220 resistors between the microcontroller and the output pin and will sink or source 20mA.

Terminals B and D can be programmed to output a PWM signal. Flowcode components for the PWM outputs and LCD display are available.
