Driver firmware - PbHUB
how do you transfer or play new firmware or driver firmware to the Pb.Hub, for example?
I bought the ISP stick, but where do you connect it or do i need it not ?
An illustrated instruction would not be bad!
Hi @Skink the PbHub comes preinstalled with the necessary firmware Are you intending to write custom firmware for the PbHub? Since its not the standard atmega but a much smaller package, I dont think its possible other than to solder some tiny wires directly to the mosi and miso, sck etc pins of the chip which would be difficult considering how small it is
No I didn't want to write my own firmware, only I asked myself what the ISP-USBASP programmer is meant for!
Or do I not need it at all with the M5Stack !?

@skink the programmer is invade you want to create your own firmware or update existing firmware. Some of the devices use GRBL which often gets updated with new firmware. The servo module and my own servo unit use the same Arduino firmware which can be updated using the adapter. Also the isp can be used when direct usb programming doesn’t work.
@Skink Short answer: No you don't need it for normal use of any m5stack product. It is only required if there is a major update to any m5stack product that doesn't have a usb port
Now I have understood what the ISP program adapter is good for

@Skink do you still have the source code from https://github.com/m5stack/PbHUB/tree/master/PortB_HUB/Firmware ?
