Re: SAMD51J19 Port

Want to add that the reason I want to move to the SAMD51 is it's about 1/2 the cost of the STM32 and it's wildly popular. I'm using them now with embedded C.

SAMD51J19 Port

Hi, I've been a user of uPython for a while using the STM32F405. It's a fantastic language and have used it in several industrial applications. I've also been evaluating several of the Adafruit boards such as the Metro M4 Express using CircuitPython. Not as impressed. The issue I have with CircuitPy...

Re: Potential Bug

Same thing happened to my custom board which replicated the Pyboard. So I kind of doubt it's a connector issue. Besides, the clone board has been working perfectly since I built my own 1.13 kernel.

Re: Potential Bug

os.mkfs is not recognized with PYB version. Seems mkfs is not a method contained in os. It's for WiPy according to the link you referenced. I had tried another PYB with V1.13 and it failed as above. I tried both DFU Util in Ubuntu 18 Linux (in VMware) and ST DFU programmer in Windows 10. Also, this ...

It seems to be an issue with V1.10. Using PyBoard V11. V1.3 doesn't have this issue, as far as I can tell.

Re: Potential Bug

Try it exactly as I mentioned.
I tried it on both V1.1 and V1.3.
Be sure to press the USR button afterwards. Then press Ctrl-D.

Potential Bug

I found an issue with the PyBoard running MicroPython V1.x. Enter the following code in REPL. from pyb import Pin PB3 = Pin("B3", Pin.IN) PB3.value() #reports 1 Now if you press the USR button and release it, then issue a Ctrl-D at the terminal, the board will go into a fault state with LED's blinki...

Re: Remove "dirty" in boot message

I did a "git status" and it did correctly report the changed files. I added an additional directory for my board (which is a derivative of the PYBV11). My problem is that I would like to update the repo, but I'm scared to do this as I don't want to mess things up. I do have my own repo (github/aeros...

Remove "dirty" in boot message

Hi, I've built a few micropython kernels for the STM32F405 boards using the PYBV11 as a template. However, the message listed on boot says something like "dirty-xxxx" where xxxx appears to be some hash. If I remove the .git folder, this goes away. Is there some flag I can set so I can leave the .git...

Re: Pyboard V1.1 UART1 Pin Change

I seem to have it working now.
I can leave the USB FS enabled but comment out the pins associated with it.

// USB config
#define MICROPY_HW_USB_FS (1) //leave as is
//#define MICROPY_HW_USB_VBUS_DETECT_PIN (pin_A9)
//#define MICROPY_HW_USB_OTG_ID_PIN (pin_A10)
