STM32C011J4M6 programming pins and timer example ?

[Glodhi]

1. Please suggest the pin for programming interface or documents 

2. Programme example for tick timer, two external interrupts? library

Programming Interface Pins (SWD)

Even in the 8‑pin SOIC package, the STM32C011J4M6 exposes the full SWD interface.

✔ Recommended SWD pins

Function Pin Notes

SWDIO	PA13	Bidirectional debug data
SWCLK	PA14	Debug clock
NRST	PA0	Optional but strongly recommended
VDD / VSS	—	Power + ground

These are the same pins used on all STM32C0 devices.

✔ Official documentation

You’ll want these three documents from ST:

• Datasheet (STM32C011x4/x6)

• Reference Manual (RM0490 — STM32C0 series)

• Errata Sheet (always worth checking)

You can find them on ST’s product page by searching “STM32C011J4M6”.

Minimal Example: SysTick + Two External Interrupts (HAL)

Below is a clean, minimal, reproducible example using HAL. It demonstrates:

• SysTick running at 1 ms

• Two EXTI lines on PA1 and PA2

• Interrupt handlers toggling flags

• No CubeMX required

... (code snippets and explanations follow) 

Notes:

- the toolchain was recently upgraded  to STM32Cube for VS Code - STMicroelectronics 
and many existing tutorials... dont reflect that yet,

- try the STM32 Sidekick (chat button down right corner)
