Re: UART with GSM SIM800L

Sorry for the double post :? So, I tested what you suggested Roberthh and it did not work at first. Then I try to switch the TXD and RXD pins...and it worked...now, I know what you think but I checked again and my pins were correctly linked to the RXD and TXD of the board, at least the pins wrote as...

Re: UART with GSM SIM800L

Hello @gabi, If you think that the connection is right (TX(Wipy) to RX(GSM), RX(Wipy) -> TX(GSM), GND to GND), the I would first verify that WiPY can send and receive. The simplest method would be to just disconnect GP16 and 17 from the modem and join GP16 and GP17. Then you should receive back wha...

Re: UART with GSM SIM800L

Did you connect TX from the UART to RX on the SIM800? And RX from the UART to Tx on the SIM800? And also connect grounds beteween the two devices? Hi :) Yep, I have linked every pins from the WiPy to the GSM board: the GND and the 5v (from an USB cable that I have customize) (I have the LED flashin...

UART with GSM SIM800L

Hello guys (and girls), I am currently trying to work with a GSM module: the SIM800L ( http://wiki.seeedstudio.com/images/4/46/SIM800L_Hardware_Design_V1.00.pdf ) I connected my UART 1 Pins to the RX and TX of the board but I could not get anything from the board: when I send an ATI message, I get n...

Re: SPI and MFRC522 Module: SPI read/wirte not working

Hi, a while ago, I ported exactly that library you mentioned for WiPy and ESP. You might want to have a look at the results here: https://github.com/wendlers/micropython-mfrc522 regards, Stefan Hi, Oh, that's great, thank you! :) I've took a look and I have some questions ^^ - In the __init__, Why ...

SPI and MFRC522 Module: SPI read/wirte not working

Hello everybody! After a while, I finally get back to play with my WiPy :D So, I want to use a RFID reader module: the MFRC522 ( http://www.nxp.com/documents/data_sheet/MFRC522.pdf ) I found a python library on github: https://github.com/mxgxw/MFRC522-python And I want to make it work in micropython...

Re: Read temperature with TMP-36 and WiPy ADC

Hello, As stated in the docs, the maximum input on the ADC pins (when used in ADC mode) is 1.4V. What value are you feeding into GP3 (or any of the other ADC pins)? If you put more than 1.5V when the pin is in ADC mode you will damage it. Cheers, Daniel Hello, Yes, I saw that already and my calcula...

Re: Read temperature with TMP-36 and WiPy ADC

Hi Daniel, Thank you very much for your reply :) (and sorry for the late answer, I did not see it before ^^") Here are the software running on my WiPys: (sysname='WiPy', nodename='WiPy', release='1.0.0', version='v1.4.6-21-gff736d6 on 2015-09-27', machine='WiPy with CC3200') and (sysname='WiPy', no...

Re: IRQ on Pin throwing TypeError: can't convert to int

@Gabi the definitive guide is here http://docs.micropython.org/en/latest/pyboard/reference/isr_rules.html Thank you for that :) Well, I have decided to store the callback as a global variable in order to be able to get the IRQ flag to know whether the handler has been triggered by a RISING or a FAL...
