I don't know anything about the platform you are using, but I have a compact CA service I wrote years ago that uses around 29K and runs on some low-end Rabbit-based modules with just 512K flash and 512K SRAM and running at 22 MHz. These controllers are running
a "soft" RTOS I wrote based on the standard POSIX-compliant APIs used in Unix and Linux systems.

for a small side project I'm working with a board featuring an ESP32-WROOM-32E module [1]. The module itself has WiFi and an EMAC core which is connected to an ethernet PHY on the board (10/100Mbps). Also there are some sensors connected to the module. At the moment I have a small program running on the board, that connects to ethernet, gets it's IP via DHCP and starts listening on a TCP port. If a message is received the corresponding sensor data is send as an answer. The chip is running a modified FreeRTOS kernel and I started to wonder, if it would be possible to port EPICS on that module. Does anyone have experience with the ESP32 and tried running EPICS on it already? If not, anyone has an idea for a good starting point for such a project? A CA server that provides the sensor data as PVs would be enough.
