I bought 3 Ai-Thinker ESP-C3-12F-Kit at Banggood, which cost only 13.00 Euros with 4MB Flash. In contrast, the 2 Waveshare ESP-C3-32S-Kit, with 2MB Flash, which I had bought before, cost 18.99 Euros. That was the good news, now for the bad. For testing, I have uploaded a simple, already existing Ard...

Floating point not supported ???

Unfortunately yes, the ATSAMD21 does not have a floating point coprocessor and MicroPython does not emulate floating point calculations in assembler. Floating point instructions

In the meantime, I have made tests with several STM32 boards that are available to me: ADAFRUIT_F405_EXPRESS, BLACK_F407VE, PYBV11 and WEACT_H750 Since all boards are affected, I have renamed the subject from [BLACK_F407VE] to [STM32]. Originally I followed the instructions in Getting Started . I al...

First I built the firmware, uploaded it via DFU and did first tests with Thonny, so far so good. Then I wanted to use my W5500 module also in MicroPython and built the firmware with the option MICROPY_PY_WIZNET5K=5500, here I got a bunch of errors. What did I do wrong? mike@mpc4:~/micropython/ports/...

I think Thonny needs pyserial and serial is something else.

Hello jahr, thanks for the quick reply and sorry, that was my mistake. :oops: I had already read all the information that WeAct offers, including the information you linked, but had overlooked the fact that WeAct offers an ExternalLoader for downloading and had therefore worked with a different down...

The build has worked well so far with these board definitions.

As I have since discovered, the installed files are called exactly the other way round than the packages. :roll: mike@mpc4:/usr/bin$ ls arm-* arm-none-eabi-addr2line arm-none-eabi-gcc-8.3.1 arm-none-eabi-ld.bfd arm-none-eabi-ar arm-none-eabi-gcc-ar arm-none-eabi-nm arm-none-eabi-as arm-none-eabi-gcc...
