Memory-mapped I/O for MCU peripherals
Peripheral register work: volatile pointer casting, bitfield mask idioms, and read-modify-write patterns.
Dev Log
Embedded firmware development
Embedd engineering guides cover driver generation, chip bring-up patterns, register map analysis, and CI/CD integration.
Interrupt support in generated peripheral drivers
How Embedd creates ISR-safe accessors and enable/disable stubs for interrupt-driven peripherals.
Supporting NXP, TI, ST, and Nordic chips
We validated 60+ chips at four major vendors and found distinct extraction challenges in each datasheet format.
Testing firmware before the hardware arrives
Use Embedd's test stub output to create a register mock layer for running peripheral driver tests on a host machine with GCC.
How RISC-V and ARM driver generation differs
How the ISA shapes datasheet conventions, address map layout, and the bitfield accessor patterns Embedd generates for each architecture.
Finding register addressing errors at chip bring-up
Five frequent register addressing errors in chip bring-up, plus how traceable accessor generation keeps them out of production.
Generating SPI and I2C drivers, step by step
Follow the process from uploading an SPI/I2C peripheral datasheet and checking its extracted register model to using the generated driver in a CMake project.
Peripheral driver patterns on ARM Cortex-M
See how the Cortex-M memory model, CMSIS naming conventions, and vendor address map choices determine Embedd's bitfield accessor patterns.
Extracting structure from embedded datasheet PDFs
Inside Embedd's extraction engine: handling multi-column tables, rotated text, inherited column headers, and register blocks spanning pages.
A firmware engineer's guide to chip register maps
Register maps, bitfields, and memory-mapped I/O: first principles behind Embedd's generated output.
How the Embedd workflow works
Follow a chip datasheet from PDF to compilable driver with Embedd: extraction, model generation, output formatting, and smoke testing.
Comparing STM32 HAL driver generation times
We compared three engineers writing STM32 GPIO, USART, and SPI drivers by hand with generating them through Embedd, across 9 peripheral types.
