This page is to remind for my private company
I was established my company "Homemat" around 2008. I was able to reach some necessary targets, like PLC hardware prototypes, system concept, bootloader, several software components. I was successfull on technical topics, but the problem was to sell it. I am not good in merketing. Therefore it was stopped slowly, especially because I was not necessary, I was able to live without it.
Now, after 10 years, during renewing my own real estate, I was searching for my hardware again. But there is no Windows XP any longer, there is no PC with on board serial port. There is Windows 10 and USB-Serial converter, but those softwares are not working any more on these PCs. Furthermore I do not have Windows at home for a while, just Linux. I just read the microcontroller (MC68 HC908GZ60) user manual regarding monitor interface and realized it is not so difficult. I wrote the necessary services in C language on Linux that way to operate also with USB-Serial converters. This can be found here: gzml, means GZ type microcontroller Monitor Loader. This knows exactly what are needed to download my bootloader. Full memory erase, write flash memory from file S19. Of course I needed another compiler too, since old one is licensed to my old company where I worked. Since I like to write software in assemly, I have selected ASM8. This supports Win10 and Linux too. With these I can use my PLC hardwares again.
