Like the idea to have all ends open.
Maybe they can share information about the bootloader, there will be some open minded thinking necessary on the Itead side!
i have Nextion NX3224T028 and MCU was damage, i resoldering MCU but can't find firmware to program. Can you help with binary file or better with sources :)
Tanks in advance
Mitek did you ever get an answer to this?
I'd even be happy with purchasing just the chip preflashed so I could repair my 3.2 tft
Which Nextion model has the STM32F030R8 (.T6?) ??
Yes, it is the STM32F030R8T6 on my 3 boards.
Which Nextion models ?? The R8 is better than the C8 ... so which models?
My mistake, tookk a better look in closeup: it is the STM32F030C8T6 on the NX3224T024_011, NX4827T043_011 and NX8048T050_011 and not the R8 version...
I was really hoping for extra SRAM and more internal Flash :)
I hoped for a more open firmware to use the UART without the prefix/suffix limits.
I am not sure by what you meant as open firmware, and which prefix/suffix limits. Care to expand.
Have control over the UART, now an Arduino is talking to the nextion and is talking to other serial devices.
I would be 'more elegant' to program the nextion talk to other serial devices, in full control of its UART.
That is the firmware's interface. A lot of work to take over control of the UART (or bit-banged serial over GPIO is what I think was really done), and then there is the issue of redoing the IDE/HMI to reinterface with the firmware that makes the HMI function.
That was the question to gain control of the STM32, it has more power then a general small arduino.
I do understand it has lots of other issues to deal with.
