Examples code for Padauk µCs to be compiled with the Small Device C Compiler (SDCC)
License: Other
These are code examples for Padauk Microcontrollers. Suitable simple boards for can be found at: https://github.com/free-pdk/f-eval-boards They are meant to be compiled with the Small Device C Compiler (SDCC), version 4.0.0 or later. The count-s08 demo has been tested using PFS172 on the f-eval-pdk-s08 board. The count-s08a demo has been tested using PFS154 and PFS173 on the f-eval-pdk-s08a board. The count-s16 and hello-s16 demos have been tested using PFS154 and PFS173 on the f-eval-pdk-s16 board. Other configurations have not yet been tested. Currently, there are 5 demos: * count-s08: A timer / LED example for the PFS122, PFS172, and PGS134 (e.g. on the f-eval-s08 board). * count-s08a: A timer / LED example for the PFC151, PFC154, PFC161, PFS123, PFS154, PFS173 (e.g. on the f-eval-s08a board). * count-s08b: A timer / LED example for the PFC161 (e.g. on the f-eval-s08b board). * count-s16: A timer / LED example for the PFC154, PFC232, PFS132, PFS154, PFS173, PGS134, and PGS152 (e.g. on the f-eval-pdk-s16 or f-eval-pdk-s16a board). * hello-s16: A serial output example for the PFC154, PFC232, PFS132, PFS154, PFS173, PGS134, and PGS152 (e.g. on the f-eval-pdk-s16 or f-eval-pdk-s16a board). * timer_irq_blink: An example ported from MINI-C to SDCC. * watchdog: An example ported from MINI-C to SDCC.
Current SDCC uses __sdcc_external_startup (and actually uses the return value). The examples need to be updated accordingly.
Please add a LICENSE file to the project.
Something like MIT or similar would be highly appreciated.
I tried to compile the hello pfs154 and saw that the const string "Hello World!" is placed in code memory const section byte by byte (2 byte per instruction word).
The PFS154 only can store 14 bit per instruction word which means that 2 bits of every second byte will be missing.
I think a byte array like "const char*" should use 1 instruction word per byte (wasting the upper bits).
BTW: Since this is a sdcc related thingy what would be best place to report this kind of problems?
