Mbed 4dGenie class
Dependents: Genie_Test 039847382-S3_DS1621_and_LCD_V1
This is a work in progress.
4dGenie class to use with 4dLCD screens that are using the genie environment.
There are still some rare occasions where the 4dLCD might crash, for now i have no solution to this except doing a reset of the 4dLCD.
Please make sure to have the most up to date PmmC loaded on the screen.
usage example :
Mbed4dGenie test program
#include "mbed.h" #include "mbed_genie.h" DigitalOut myled(LED1); /* The Mbed4dGenie class requires 3 parameters 1 - Tx pin 2 - Rx pin 3 - Reset pin */ Mbed4dGenie lcd4d(PTE0,PTE1,PTB9); int main() { int temp = 0; printf("Mbed Genie demo \n\r"); lcd4d.Start(); /* for example, in this loop we increment the thermometer0 object from 0 to 100 */ while(1) { if(temp >= 100) { temp = -1; } else { temp++; } lcd4d.genieWriteObject(GENIE_OBJ_LED_DIGITS,1,temp); myled = 1; wait(0.05); myled = 0; wait(0.05); } }
