Thank you for your huge help,
I am optimistic and 2,3,5 should work!
Thank you also for pinMode https://www.espruino.com/Reference#l__global_pinMode and 'modules' link, https://www.espruino.com/modules/
both are great,
now I found js codes
Ok, so I checked Pixl.js documentation.
I didn't get anything maybe I am just dumb.
According to Pinout https://www.espruino.com/Pixl.js#pinout of Pixl.js, there is a Note:
"Pixl.js has one available I2C, SPI and USART (and infinite software SPI and I2C). Unlike other Espruino boards, these peripherals can be used on any pin."
However, I also found additional information when I put my mouse cursor on these "!" two descriptions on D0 and D1 pins:
D0 - "Serial Console RX when Bluetooth is disconnected"
D1 - "Serial Console RX when Bluetooth is disconnected"
Moreover, "Purple boxes" show pins that are used for other functionality on the board. You should avoid using these unless you know that the marked device is not used.
I don't see "Purple Boxes, I see "Purple circles" on the PCB layout https://www.espruino.com/Pixl.js#pinout
Further below there are "Purple boxes" with "Pins not on connectors.
H0 3.3v LCD
H1 3.3v BTN1
H2 3.3v BTN2
H3 3.3v BTN3
H4 3.3v BTN4
H5 3.3v LCD
H6 3.3v LCD
H7 3.3v LCD
H8 3.3v ! LCD
H9 3.3v LCD
In conclusion I have a few pins rs-232 cables 2,3,5,7,8 ready and no idea where to put them in pixl.js
To which Espruino devices I can solder pins and get data from rs232 port
I'm going to decode NMEA data from external GPS/GNSS receiver (it is a Novatel Flexpak6 RS-232 DB9)
Which Espruino Board can I use to read and store rs232 data (it is ASCII format NMEA, ?
How to connect pins to the espruino board?
There is no power on the pinout of Novatel's rs232 com1 port as follows
1 COM1_RTS/422TX- 8
2 COM1_TXD/422TX+ 2
3 COM1_RXD/422RX+ 3
4 COM1_CTS/422RX- 7
11,14 Ground 5
I want to grab some data from rs232, use that data for GPS position computation, and I want to store data and export it from espruino board.
Which equipment do you suggest?
Temperature sensor Example for Bangle2:
I used some codes from Espruino channel from youtube.com and from existing repositories here: https://www.espruino.com/modules/
