ESP8266 with IMU, Barometer and Battery

esplocalizer

##ESP Localizer Board The esplocalizer-tight design is open source and leverages the versatility of the ESP8266 microprocessor and WiFi along with the 10 degrees of freedom sensors and integrated battery controller. The unit comes with basic sensor code loaded and tested on the board.

##ESP-12-F: ESP-12F WiFi module is developed by Ai-thinker Team. core processor ESP8266 in smaller sizes of the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode, Clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antenna. The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users can use the add modules to an existing device networking, or building a separate network controller. ESP8266 is high integration wireless SOCs, designed for space and power constrained mobile platform designers. It provides unsurpassed ability to embed Wi-Fi capabilities within other systems, or to function as a standalone application, with the lowest cost, and minimal space requirement.

##BMP280: BMP280 is an absolute barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow for the implementation in battery driven devices such as mobile phones, GPS modules or watches

##LSM9DS1: The LSM9DS1 is a versatile, motion-sensing system-in-a-chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DOF) in a single IC.

##STBC08: The STBC08 is a constant current/constant voltage charger for single-cell Li-Ion batteries. The ESPLocalizer comes with a connector for hubsan-type lithium ion batteries.

esplocalizer's Issues

Missing PCB file in hardware

I would like recreate this device but the hardware section is missing the pcb file. Could it be included in the repository?

Fast Acc CSV Stream is empty file

I'm having trouble reading the accel and gyro data from a websocket. The default /firmware-c web interface gives a link to the CSV file, but I'm getting 0 bytes or "unable to connect" errors at /d/fastacc.csv

I'm able to create websockets to these endpoints I found in the source:
/d/ws/echo
/d/ws/evaltest
/d/ws/issue

My hunch is I'd have to create a new endpoint: /d/ws/fastacc which the ESP sends websocket packets to connected devices through.

The web interface and fastacc() in /firmware-c/user/user_main.c looks like the device should already be sending this data, I'm not sure the endpoint to connect to or if this is a problem with my setup.

When I click on the Fast Acc CSV link in web interface, this function should write to socket. 'Save link as' doesn't make a difference:

static ICACHE_FLASH_ATTR void fastacc()
{
	//char mydat[128];
	//int len = URLDecode( mydat, 128, curhttp->pathbuffer+8 );

	char buf[1024];
	int times = 20;
	int len = 0;
	int16_t data[10];

	if( first_acc == 1 )
	{
		first_acc = 0;
		len += ets_sprintf( buf+len, "gx, gy, gz, ax, ay, az\r\n" );
	}

	for( ; times > 0 && lsmhead != lsmtail; times -- )
	{
		int16_t * data = &lsmdata[6*lsmtail];
		lsmtail = (lsmtail+1)%LSMBUFFERSIZE;
		
		len += ets_sprintf( buf+len, "%d, %d, %d, %d, %d, %d\r\n", data[0], data[1], data[2], data[3], data[4], data[5] );
	}

	if( len )
	{
		START_PACK;
		PushBlob( buf, len );
		END_TCP_WRITE( curhttp->socket );
	}

	if( i2cmode == 0 )
	{
		curhttp->state = HTTP_WAIT_CLOSE;
	}

}

esplocalizer firmware-c example missing files

Cloned esp82XX-basic example compiled and flashed to esp without issue. Everything works great.

Unable to do make all in /esplocalizer/firmware-c, compiler missing 'lib' files. What does libmain.a do and where can I get it :) ?

Missing annotations in schematic ( Component: U5 Regulator )

What is the power consumption in sleep mode?

Is it < 20 uA?
That would make it a really useful IoT device.

Which LDO did you use?

Can you please expose more information on the parts you used? Especially the LDO you used.

How to fix it?

Fails to start wifi

New install following instructions, cloned esp82XX-basic example, successfully flash firmware with "make burn" and "make burnweb" (no errors), but doesn't start a wifi hotspot. Serial output on reset shows:

esp82XX Web-GUI

Boot Ok.

I'm not sure how to debug why the Opmode would be 0 (wifi off) for this example project. Any pointers would be really helpful, thank you!

Autoimporting KiCad pretty footprints from hardware/*.sch

Hello @cnlohr,

Thanks much for publishing your projects as open hardware as well as the firmware, always inspiring stuff to learn from you.

I have been trying to reuse your .sch since I have a couple of modifications in mind to your design.

Sorry if this sounds obvious (I'm a relatively new KiCad user), but how can I auto-import the footprints for pcbnew without manually importing each .pretty library/module? as the KiCad docs state, i.e:

https://github.com/jdunmire/kicad-ESP8266

I thought about giving this giant meta-pretty-repo a shot, but the ESP footprint doesn't seem to be there:

https://github.com/monostable/kicad_footprints

I understand you might be using your existing installation/footprints from past projects, but what would be your advice to semi-automate this process of importing footprints?
