STM32G030 support.

Hi,

I have not tried G030 yet, I just added support for G031 and G0B1 and found those to be very different.

G030 is a "lite" version of the G070 which is looks like supported by code already but really it is not. There are some mistakes in definitions (the project do not compiling from the box) - I used the G070 code as a starting point for G030. May be you can finish support for G070 near time? This will make G030 support also.

I will look into building G070 correctly, I cannot run code because I don't have any HW right now.

Hi.
I looked the ERRATA sheet (https://www.st.com/resource/en/errata_sheet/es0486-stm32g030x6x8-device-errata-stmicroelectronics.pdf) for the STM32G030 and was find this:

Code: Select all

2.2.4 DMAMUX cannot be synchronized or triggered by EXTI
Description
The EXTI-related DMAMUX synchronization and trigger inputs are wrongly routed to the it_exti_per(y) output
instead of being routed to the exti[15:0] output lines.
The it_exti_per(y) signals are not usable for synchronizing and triggering DMAMUX.
Workaround
None.

I do not understand may be this is the cause of the my problem?

Sorry.
I found the problem. It is wrong settings in configuaration of the ADC:

Code: Select all

    //cfgr1
    0
    | ADC_CFGR1_CONT           <<<---- THIS BIT IS WRONG SET!!!! IT DOES NOT NEED FOR THIS MODE
    | ADC_CFGR1_RES_12BIT
    | ADC_CFGR1_EXTEN_RISING
    | ADC_CFGR1_EXTSEL_SRC(3),

I understand that "not having hardware" is a problem. I just don't understand why you can't accept "let me send you some hardware then" as a solution ?

I prefer to work with standard nucleo boards, I ordered some.
