Have you tried this on actual CC3200 architecture or just unix version? There seems to be an error with this line: any help appreciated. >>> s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: no such attribut...

Found this on timer synchronization, but am lost in translation. https://github.com/micropython/micropython/wiki/STM32F405-Timer-Triggering Then this code: https://www.rapitasystems.com/blog/chaining-two-16-bit-timers-together-stm32f4 /* enable the timer peripherals: */ RCC->APB1ENR |= RCC_APB1Perip...

What is the easiest way to synchronise two timers, say Timer 1 and Timer 8 ? At first sight, micropython is seemingly unable to guarantee realtime execution of two subsequent lines of code, which is crucial for exact timing sequences. Random time delays occur between the exectution, possibly to mic...

Hi, Edit: Now it works, updated from github, compiled with macports, failed with crt0.s missing, continued compilation with 4_9 toolchain and it worked. Have no idea what has changed, except upgrading from github. Original: installed fresh gcc-arm-none-eabi-4_9-2015q2 from https://launchpad.net/gcc-...

Found the only solution that works, but the code is definitely buggy. Follow the previous post for code setup ### MASTER: >>> i2c.scan() [] ### SLAVE: >>> i2c I2C(2, I2C.SLAVE, addr=0x42) >>> i2c.recv(3, addr=0x00 , timeout=122000) ###MASTER: >>> i2c.send('abc',addr=0x42,timeout=100000) ###SLAVE: b'...

Reporting similar issues. I can not get the I2C SLAVE talking back to I2C MASTER. However, both devices do work with a designated I2C slave digital potentiometer flawlessly. ############## SLAVE device ########### import pyb from pyb import I2C from pyb import Pin pyb.freq(168000000) i2c = pyb.I2C(2...

testing WiFly RN-171 wifi module with stack plugged on UART3.

Correct.

Thank you for the pyboard.py example, looks like Ctrl+a, Ctrl+b Ctrl+c Ctrl+d all are implemented, perfect!
