I have not looked at the asm for ESP32, but it is quite the chip. I now the Arduino IDE has a model for it, Anyone thought about porting GCB to if it is microchip or AVR like inside? I do not like C, but have been using it with the ArduinoIDE just to play with the chip. Cheap, lots of i/o, wifi, blue tooth...

I took parts of code and made the below program. The LCD shows > 13 on the screen. Temp is 13 for some reason, and if I jumper (no keypad yet) D7 to D8 still 13 on display? Any ideas #chip mega328p, 16 #include <UNO_mega328p.h> HI2CMode Master #define HI2C_DATA #define LCD_IO 10 #define LCD_I2C_Address 0x4e '// Change to 0xFE for SainSmart ELSE 4E #define LCD_Backlight_On_State 1 '// These may need to be reversed #define LCD_Backlight_Off_State 0 #define KEYPAD_ROW_1 DIGITAL_11 #define KEYPAD_ROW_2...

4.7K pull-up seems to have done the trick. Thanks Will have keypads today and give the real test.
-
OK, another question. Anyhone have a 3x4 or 4x4 routine? None of the info mentioned pull up or down on anything, So I pulled from the examples and jumped D7 and D8

The below code displays > 13 on the LCD I jumper D7 and 8 and no change as well. Any ideas? ~~~ #chip mega328p, 16 #include <UNO_mega328p.h> HI2CMode Master #define HI2C_DATA #define LCD_IO 10 #define LCD_I2C_Address 0x4e '// Change to 0xFE for SainSmart ELSE 4E #define LCD_Backlight_On_State 1 '// These may need to be reversed #define LCD_Backlight_Off_State 0 #define KEYPAD_ROW_1 DIGITAL_11 #define KEYPAD_ROW_2 DIGITAL_10 #define KEYPAD_ROW_3 DIGITAL_9 #define KEYPAD_ROW_4 DIGITAL_8 #define KEYPAD_COL_1...

Since this is my thread. I will post here. I grab some code and made the below. Keypad it on order, but will just short a row and column. When I run it I get my "> " and 13 (with no row/col shorted. If I short 7 and 8 still a 13 on display. Anyone see what I missed? ~~~ #chip mega328p, 16 #include <UNO_mega328p.h> HI2CMode Master #define HI2C_DATA #define LCD_IO 10 #define LCD_I2C_Address 0x4e '// Change to 0xFE for SainSmart #define LCD_Backlight_On_State 1 '// These may need to be reversed #define...

I made a post and do not see it. Going to bump this thread and see if somehow my account is not working. I get GCB stuff all day. I posted and like it never made it. I guess mods have to approve new topics or something (if I see this comment show up). Like to get keypad working this weekend...

I have never use the Arduino IDE (other that the (ESP). Only GCB on uC/AVR. On TX/RX high. The user has used two NANOs and same results. I will be on vacation tomorrow and bread board it with 2 LEDS and see what I get. Workng with someone that likes Arduino, all new to me. Normally I use a PIC and AVR and asm or GCB.
-
I will update the compiler tonight and see if that helps. Not sure on not enough info either time... Last post has source code, error and assembler program name. Also, first post on the UNO assumtion, in the title I mentioned the Arduino name (NANO),. Also lost on the Y or N part?

chip mega328p,16 dir portd.0 out dir portd.1 out do portd.0=!portd.0 portd.1=!portd.1 wait 1 sec loop Get gcasm symbol 11.0 has not been definded
-
Teaching someone GCB and wanted a full 8 bit port got a 5.5" 7 segment display, can use PORTC and fake the one bit, but I wanted to keep it simple.
-
It is a NANO. But seems the same issue as the UNO. Should I not be able to set portd.1 off and drive it down. The USB cable was use to program it via the bootloader, but was not connected when in-circuit. Power is running on RAW pin using the onboard regulator. Hope someone has figure it out before.
-
I want to use PortD on the Mega328p. For some reason PortD.0 (RX) and PortD.1 (TX) are always high (can not set off)? Is this a Arduino bootloader issue as they are marked TX/RX? Maybe I have a bad nano. Anyone found this before?
-
Opps. Works if I flipped the #define parameters, works both ways. Had I/O and equate/label flipped.
-
Thanks Stan. PD2 and PB5 from nano. Thanks.
