It works fine, when i switched to the old commit 27.07.2016 with same mpconfig and same code. I think it's a bug. Strange

the code ist simple

what happened if you don't use Switch Button. I'm using STM32F407 on my modified Board similar to Discovery Board without Switch.

Before built, i've disabled has_switch to 0 on mpconfig, I think, it would nothing happen if you press ctrl +c during while loop without using switch button there.

Hello,

i have tested recent build of micropython on STM32F407 Discovery Board, Unfortunately the KeyboardInterrupt 'ctrl+c' does not work, no effect. The build about 3 weeks ago, it worked well. I've using minicom on OSX10.5

Does anyone know, how to solve it.

Thanks in advance.

LOL , i have still connected BOOT0 to VDD. now it works thanks!! Welcome to minicom 2.7 OPTIONS: Compiled on Oct 17 2015, 05:42:37.

i've deployed as you suggest make USE_PYDFU=0 BOARD=STM32F4DISC deploy Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

in the meantime i tried with
Now i see 2 removable devices. "DIS_F407VG and PYBFLASH". Should i deploy the firmware as you suggest?

Thanks.

That should no longer be the case. The PWM LED support is now configurable, and the STM32F4DISC board definition doesn't enable PWM for any of the LEDs, so all of the timers should be available. Are you using recent firmware? Thanks for reply. i'm using "Micro Python v1.4.4-11-gc8870b7-dirty". I ju...

Hello,

micropython build on STM32F407 Discovery Board does not support TIM3 for PB4, PB5. Micropython says, TIM3 is used for System Timer.

Is it possible to change the Sys Timer as TIM2, or TIM4 ? I have to use PB4, PB5 as PWM

Thanks in advance. Sorry for my bad english.

done!!

for write:

data = bytearray()
data.append(0x90)
data.append(0x47)
data.append(0xFF)

i2c.send(data, SLAVE)

for read:

data = bytearray()
data.append(0x10)
data.append(0x47)

i2c.send(data, SLAVE)
i2c.recv(1, SLAVE)

Hello, i'm trying to understand the write and read sequence of I2C implementiation on micropython and i would implement the following write and read sequence of an sensor on the image. read.png i2c.mem_write(0x47, 0b1010000, 0x90) i2c.send(0xFF, 0b1010000) write.png i2c.mem_write(0x47, 0b1010000, 0x...
