I haven't been here for a while and probably missed some things, but the LCD sample code for HD44780, worked on 1v44, doesn't work more on 1v63.

var lcd = require("HD44780").connect(A1,F2,A3,F4,A­2,C5);
lcd.print("Hello World!")

Could some one say why? thanks!

Hi,
I know that is because the B20 differs from S20, but could u recomend, how I can get correct temp? Now I have 3,25 °C when real temp is ~25. Will It be correct to just multiple to some koef. and\or shift the value?
Sorry for possible offtop.
Thanks.

Ok, thank you for the explanations, I keep doing my exercises :-). And also, It's really amazing project! Thanks for your job!

Hi, Gordon!
If I use

var lcd = require("HD44780").connect(A1,A2,A3,A4,A­5,A6);

It works well on My vldiscovery board, I can give out text and variables to LCD.
If use also

var sensor = require("DS18B20").connect(B1);

it gives me a lot of errors like

ERROR: Function not found! Skipping. at line 1 col 30
var lcd = require("HD44780").connect(A1,A2,A3,A4,A­5,A6);

    lcd.setCursor(4,1);

Is It the restriction of non-multitask, or someth. else? Thanks.

Gordon, I didn't say about It, because I didn't think that is affects, but i have LCD pin connected to A0. Yes, I'm an Idiot. Because of my stupidity, I stole a lot of your time. Sorry, I'm sorry.

ok, It starts working after
load()

No it doesn't, It says:

after reset button.

no, no, 'OMG' is my own addition, sorry.
dump()

sure...I tryed to include save(); on right panel, also tryed to put save() and enter - no effect..
Tryed erase chip in st-link and erase all the sectors, then download the firmware. After downloading sample code I've got

OMG!!!

Dear StuntMonkeh, could you please help and repeat the code snippet from this topic with onInit function: http://forum.espruino.com/conversations/­334/#comment3836 thanks!

I write code pasted above, download, LED1 lights, after power off-on It doesn't light. I connect web IDE LED1 doesn't light.
It stops lighting even without Off/On after reset (by reset button) also...

Yea, It lights immediately after downloading. i use VLDISCOVERY board and supply it from the USB-TTL converter.

Hi, Gordon,
thanks for firmware update, there are really no more errors during the saving, but your sample
function onInit() {
LED1.write(1);
}
save();
still don't work after power reset. Could you help?

update: moved to the Ver1.44. - everything the same.

Hi, I didn't. Try to use Ver1.44 https://espruino-nightly.noda.se/2013-12­-13/stm32vldiscovery/
but It didn't help me. I asked Gordon about It once again: http://forum.espruino.com/conversations/­334/#comment3774

Gordon, I've uploaded:
function onInit() {
LED2.write(1);
}
save();
And Led2 doesn't light after power off - power On.
I used espruino ver1.43 compiled from github.
If I upload the code from webIDE not first time, I've got the message like

save();
=undefined

There were 257 errors!
Even after reset(); save();
What the errors, and how can I manage this situation?

IDE is from chrome store

sorry, Hi, all
in web IDE if I put
require("Encoder").connect(A1,A2,functio­n (direction) {
step += direction;
print(step);
});
i get
ERROR: Function not found! Skipping. at line 1 col 20
require("Encoder").connect(A1,A2,functio­n (direction) {
at the moment I have connected internet
Gordon, what can be problem?

Thanks a lot!
According to your question, for me, I'd like to have a choice: to do it simple straight way, or using some complete procedure. I'd like to have many possibilities. LED1.write(1); it's ok for noobs like me, because it simple.

but
var1=true;
save();
saves var1.....

Hi, and thanks a lot for the explanations. Have I understand It correctly, that embeddedadventures module will not work with Espruino? Is their module workable in common? What the problem with It?

Hi, Gordon, Hi all!
according to the TI instructions I tryed to initialize cc3000. (i've got the module from
embeddedadventures)
here is the code snippet, I've used:

SPI_OPERATION_WRITE=0x01;
HCI_TYPE_COMMAND=0x01; 
HCI_COMMAND_SIMPLE_LINK_START=0x4000;
SPI1.setup();
digitalWrite(B0,0); 		// Disable the module by setting EN(B0) low 
while(digitalRead(C5)==0){};	// Wait for IRQ line (C5) to go high
digitalWrite(B0,1);			// Enable the module by setting EN high 
while(digitalRead(C5)){};	// Wait for IRQ line to go low 
digitalWrite(C4,1); 		//Set CS line (C4) high
temp1=2;
while(temp1-->0){};			// Wait 50 µs (probably it takes not 50us, is it critically?)	
SPI1.send(SPI_OPERATION_WRITE,A4);
SPI1.send(0x00,A4);			// Send via SPI: 0x00 (length MSB)
SPI1.send(0x05,A4);			// Send via SPI: 0x05 (length LSB)
SPI1.send(0x00,A4);			// Send via SPI: 0x00 (busy 0)
temp1=2;
while(temp1-->0){};			// Wait 50 µs 	
SPI1.send(0x00,A4);			// Send via SPI: 0x00 (busy 1)
SPI1.send(HCI_TYPE_COMMAND,A4);
SPI1.send(HCI_COMMAND_SIMPLE_LINK_START & 0xff); 	//Send via SPI: HCI_COMMAND_SIMPLE_LINK_START (LSB)
SPI1.send(HCI_COMMAND_SIMPLE_LINK_START >> 8); 		//Send via SPI: HCI_COMMAND_SIMPLE_LINK_START (MSB)
SPI1.send(0x01,A4);			// Send via SPI: 0x01 (1 byte payload)
SPI1.send(0x01,A4);			// Send via SPI: PatchesRequest (0x00 = Don’t load patches 0x01 = Load patches) 		
digitalWrite(C4,0); 		//Set CS line low
while(digitalRead(C5)==1){};	// Wait for IRQ line to go low
ans = SPI1.send(0x00,A4);

monitoring "ans" variable by lcd indicator shows me always zero, but must contain the answer from the module.
what is my mistake ?

I'm terrible sorry, for my previous topic, I just forgot to set jumpers CN3, responsible for swd programmer mode.
Sorry again.

Hi, Gordon, hi All!
After dodwnloading some code like A#.write(1); B#.write(1) etc. , I've checked that It works.
then I put reset(); command, and the board stoped and couldn't connect again. But trying to reload the board thru the ST-Link utility i see only "couldn't connect to target" and recomendation from this forum to download thru the "press and hold the reset button of the board and choose the Menu item "Target" -> "Connect" (or click on the connect icon). Release the reset button." doesn't work even after tens of attempts.. ouhhh, did I kill It ???

Update: I connected thru the terminal, and now the log looks like =undefined

echo(0);
=undefined
save();
=undefined

Whath the errors? how can I reset the board?
Thanks!

Dears! Sure, a lot of people here looking forward for espruino based WEB/Wi-fi/CC3000 solution, aren't they? I'm itching to have small device for tricks, controlled from the web...
