In order to have some more space and use the internal /flash instead of the /sd
What would it take to get mpy working on the STM32F469BI: 2MByte Flash and 384kByte SRAM?
Regards,
R.

use of select.poll() with multiple uarts
I work with three serial ports and I would like to handle these within the program. So I use USB-VCP exclusively for debugging. I have an uart 3 that communicates to a host, I have uart 1, uart 2 and uart 6 ready to go. So data may be coming from everywhere. How does one use the select.poll() in suc...

Re: Baudrate port 6
Oops, I fixed it: The parameter for the 16MHz xtal alone was not enough %^&*( (I use this instead of 8MHz) on my own board. // in mpconfigboard.h // HSE was 8MHz but is 16MHz now #define MICROPY_HW_CLK_PLLM (16) // change to 16MHz #define MICROPY_HW_CLK_PLLN (336) // TODO: check the rest #define MIC...

Baudrate port 6
Dear all, I'm using mpy with UART 6. I have initialized it to 38400bps: port6 = pyb.UART(6,38400) Then I send a command or get something from the connected device which outputs per default on 38400bps. Well I get characters back, however not correct. So I changed to 19200 bps and now the data is cor...

Re: STM32F411CEU6-based pyboard-lite?
Dear all, Wouldn't it be great not to use all the different STM versions but create a real MONSTER board running python BARE METAL on say a ZYNC chip (giving you a lot of programmable gates (some VHDL required) and two ARM cores)? A typical MONSTER board that would do wonders: https://www.crowdsuppl...

Re: Use of flow control
@pythoncoder Peter, The behavior of RTS/CTS as being negative is correct the signals are nCTS and nRTS by definition. I have to assert (low) the signal myself so the opposite party can start sending. I was under the assumption the chip would do that. I was a bit surprised by the OSError 116 when tim...

Use of flow control
Dear all, Anyone used an UART on the mpy board with hardware handshaking. The mpy doc is rather cryptic in a sense that you initialize the USART like: import pyb ser = pyb.UART(3) ser.init(57600,flow=ser.RTS|ser.CTS) There are some pins involved so how do they need to be configured? # so do the pins...

Re: Smart Card and CCID driver
Dear pagano,
This is interesting. Is such a board available? I would very much like to play with the smartcard function of the controller.
Regards,
Roland

adding driver to pyb
Hello, I'm fiddling with micropython and creating a driver for the PCA9557. You can have up to 8 of these devices on a single I2C bus. I have looked at servo and accel as examples to roll my own. So far I can see my device appear in the dir(pyb), however I'm not done yet with passing and getting the...
