Re: Power Specifications

We will add detailed tech specs with this info to our website. In the mean time, here they are: Active (WiFi Station mode) MCU @ 80MHz ---> 14mA Active (WiFi AP mode) MCU @ 80MHz ---> 45mA Suspended (WiFi Station mode) ---------------> 850uA Suspended (WiFi AP mode) -------------------> 30mA Hibern...

Re: Porting to mbed

I just started trying to port it to another mbed board. The board has more than 100K flash, so that will not be an issue. I am still learning about the board and mbed, which might be a bigger issue in porting mircopython to my board :( Question, where can I find makembedpins.py, and do you have anyh...

Re: RedBear at Kickstarter

It seams that they made the stretch goal and will support Python: https://www.kickstarter.com/projects/1991736672/redbear-duo-a-small-and-powerful-wi-fi-ble-iot-boa/posts/1422670 To me it is not clear if this will be microPython or not. From the comment sections: We have just announced our 2 Stretch...

Re: Setting pin alternate function

Dani, While talking about the timer class, I think there should be a more accurate way to set the duty cycle. Using integers in the range of 0...100 is easy but very limiting. Another, second way of setting the dutyc cycle could be this: t1 = timer(mode=PWM, timer.A, T=1000, Tpos=500 # 50%; set peri...

Re: Setting pin alternate function

Hi, You need to provide at least the frequency for the timer channel to be initialized: tim_a = tim.channel(Timer.A, freq=10000) I know that the Timer API is inconsistent... we really need to define a proper one as part of the new Hardware API. That is what I tried first and did not work either, so...

Re: Setting pin alternate function

I have some issues getting the timer.channel part working. >>> gp = 'GP10' >>> pout = Pin(gp, mode=Pin.ALT) >>> for x in pout.alt_list(): # why should I find the alt number for PWM of the system already knows it ... if 'PWM' in x[0]: ... pout = Pin(gp, mode=Pin.ALT, alt=x[1]) >>> print('pout:', pout...

Re: running from 3v3?

To be sure I studied the datasheet: The TPS796xx PMOS-pass transistor has a built-in back diode that conducts reverse current when the input voltage drops below the output voltage (for example, during power-down). Current is conducted from the output to the input and is not internally limited. If ex...

Re: running from 3v3?

HI Daniel,

Yes works indeed with 3V3 only. Now I need to learn the WiPy and get all the network, PWM and power savings working

thanks

running from 3v3?

Hi I have a LED driver that I want to control via the Wipy to make a smart LED lamp. The driver has a 3.3 to 3.5V aux supply which I want to use to power the WiPy. If I connect this to the 3V3 pin and leave VIN open, will this work? The CC3200 should be fine with these voltages, however I do not kno...

Re: received my Wipy

Hi Dani, Both boards are working. I can connect with FTP in Chrome, however ftp.exe in win7 has some issues when using the DIR command. Using telnet (from PuTTY r0.65) is working fine too.
