@me-no-dev
it's still some programming, just at a different level
Victor Tseng
@Palatis
I dunno, I wrote the cloud service, the android app, and the mcu firmware.
total solution provider, eigh?

@me-no-dev
He expects to see something change all of the time :D
Victor Tseng
@Palatis
but I'm stall, I don't have the required hardware to continue my progress /_\
there's a 8051 used as an IO expander to control LEDs, Buttons, and some ADC. I just offload the work to a n00b fw engr. :-P
and now I have to review the hw schematics because the hw can't get the UART upload interface right...
really a headache
Me No Dev
@me-no-dev
there is also this
no BT though
Victor Tseng
@Palatis
dunno, anyway, even now, I don't get the I2S DAC, so I dunno if my "dumping wav from SPIFFS to I2S" codes works or not.
this is like super high price
E30.99
he wants to have a BOM cost of around USD$15
rejected bcm solution because the module cost $5...
esp-wroom-02 is like $2
Me No Dev
@me-no-dev
I have no idea how much esp32 will cost when out
it might be even more than $5
Victor Tseng
@Palatis
around $2 ~ $3
per 1k MOQ
Me No Dev
@me-no-dev
that is for bare chips right?
Victor Tseng
@Palatis
esp-wroom-32
Me No Dev
@me-no-dev
that is a good price
Victor Tseng
@Palatis
and because it would have enough pins, we can eliminate the 8051.
Me No Dev
@me-no-dev
I expected it to be more
Victor Tseng
@Palatis
and just connect everything back to the mcu module
yeah if you want just 1, it's $5
if buy at bulk, the price would be a lot cheaper
may even get to $1.5 or $1.75 per 10k
dunno
the smaller pcb size also cuts the price down a bit, since we don't need the 51 anymore

axTLS v2.0.0 has updated in esp8266 with arduino IDE? TLS1.2 is working now?
is TLS1.2 working now?*

@beikeland
Love the ESP8266AVRISP lib, but avrdude didn't like -P net: on windows, is there any examples of http uploading to the esp?

thats actually not a bad idea, would allow in ide flashing as well. thanks!

hi @martinayotte , I intend to make 1-6 channel touch socket wall with ESP module , I read couple of schematic for standalone touch socket which is directly control relays , also I find couple of IC with I2C interface (CY8C21234) which is probably suitable for ESP module , I was wondering if you have any clue or guide for such project
Martin Ayotte
@martinayotte
Unfortunately, I've never done such things. BTW, the Cypress chip you mentioned is probably not needed since you have already the ESP.
Maybe you could simply used an 4 channels ADC such as ADS1015
Mehrdad K
@mkeyno
I read your post , where you offer use multiplex and ESP ADC pin , but maybe it is just fit for fun project not the actual project , that's why I'm looking for a chip that can read its data by ESP
I find many design but most of them not use any MCU and work stand alone
Martin Ayotte
@martinayotte
Yes, maybe the ESP ADC with a multiplexer such CD4051. But you need to try it out. For the ADS1015, you can find cheap boards on eBay.
Mehrdad K
@mkeyno
do you know any link which is tied ESP with ADS1015 or CD4051
Martin Ayotte
@martinayotte
Using CD4051, it is only a mux, so you need some GPIOs to select the desired input, and output will go to ESP ADC. For ADS1015, it is an ADC with the mux built-in and you are driving it thru I2C bus.
So, ADS1015 is more expensive than CD4051 solution, but it takes less GPIOs.
Mehrdad K
@mkeyno
do you think process 4 sensor with mux along with other normal webserver activities will be problem for ESP?will it make unstable ?
Martin Ayotte
@martinayotte
@mkeyno , I don't see any pitfalls if properly managed ...
beikeland
@beikeland
btw was unable to use virutal serial port with the ESP8266AVRISP, suggestions on which programmer to choose in the IDE? I believe i tried all of them.
On the bright side an extremely helpfull fella on #arduino figured out how to patch avrdude
