- Thu Mar 23, 2017 10:03 am #64138 I am trying to run the following code on an esp8266-01 module with 1meg flash and I am getting the following error message...

Failed to reach end of input expression, likely malformed input
syntax error

This error happens where ever the first oledprint statement is.

I know that the advanced oled functions are only available on modules with 2 meg or more of memory, but I thought that the basic oled functions should still work on the smaller sized ram modules.

oledprint
oledcls
oledsend

I am running ESP Basic 3.0.Alpha 66

thanks

Code: Select allmemclear

- Thu Mar 23, 2017 11:43 pm #64163 For a quick test try this piece of code:

Code: Select alllet v = 100
i2c.setup(4,5)
lcdbl 1
oledcls
oledprint "Hello", 0, 0
oledprint v, 3, 3
wait

Change the I2C setup values for your own configuration, I suppose you have something like SDA = GPIO0 and SCL = GPIO2.

- Fri Mar 24, 2017 8:20 am #64173 Nope! (I had to delete the LCDBL 1) and changed the i2c.setup(0,2) [according to the docs sda=0 and scl=2 is default]

But still getting the...

Error at line 4: Failed to reach end of input expression, likely malformed input
Error at line 4: Syntax error

If I go back to the old version 2.0 A24 that is linked to on the download page it works but I have to eliminate the commas as 2.0 A26 dosn't need commas and 2.0 doesn't have 12c.setup
So this works in Ver 2.0a26...

Code: Select alllet v = 100
oledcls
oledprint "Hello" 0 0
oledprint v 3 3
wait

But this does NOT work in the latest 3.x version

Code: Select alllet v = 100
oledcls
oledprint "Hello",0,0
oledprint v,3,3
wait

Does it work for you in a 3.x version?? Specifically on an esp8266-01 module with 1Meg memory.
thanks

Code: Select alllet v = 100
i2c.setup(4,5)
lcdbl 1
oledcls
oledprint "Hello", 0, 0
oledprint v, 3, 3
wait

is working as expected on a ESP12-E and F
Version : ESP Basic 3.0.Alpha 68

I don't have around any ESP-01 module.
