Migrating from 8-bit MCU to 32-bit STM32C0, grasp it with your hands

The display system needs to be upgraded from a digital tube or dot matrix screen to a graphic display system, and it is difficult for an 8-bit MCU to meet the requirements. If STM32C0 is used, it can support multiple display modes through SPI, up to 240*240bpi, which can meet future system upgrade needs.

In today's MCU applications, 8-bit machines still occupy a considerable market with their low prices. However, the hard-core STM32C0 has emerged. With its comprehensively improved performance, complete ecosystem and excellent cost performance compared to 8-bit computers, it will definitely bring disruptive changes to this field.

We have prepared an application note (AN5775) . This document contains a migration guide from STM328L or STM328S to STM32C0 to ensure developers can quickly migrate from 8-bit MCUs to 32-bit MCUs. The STM32 development environment can greatly optimize operations, and the code volume only increases by 6% to 15%; STM32CubeMX and STM32CubeIDE tools, STM32CubeProgrammer debugging software, and STM32Cube expansion packs can optimize the development process and help reuse code or modules.
