My team and I are designing a product using the STM8S003F3.
We connect to a host controller using SPI. This works great!
Now I want to enable firmware update functionality. I started to get into SWIM protocol when I began to notice perhaps SPI can handle this as well. I can't seem to find which bootloader version is used in this chip to verify. I'm thinking this is because the chip doesn't feature a bootloader?
If that's the case will SWIM still be suitable?
