thanks for the info! I see them some time ago but just dismiss them... I already purchase some AH3503 but these AS5600 seems to be better and more easy to use and includes the magnet! ... https://www.aliexpress.com/item/4001240626350.html?spm=a2g0o.productlist.0.0.42376ca4ez05kf&algo_pvid=2bf816...

I realize that the ZG have 14 timers and the ZE only 8. That may cause a problem?

so i'd guess you may like to try 0x20018000

thanks it is quite obvious now as usual. Now I just need the hacked board!

for the stm32 z series, normally there is fsmc https://www.st.com/resource/en/application_note/cd00200423-using-the-highdensity-stm32f10xxx-fsmc-peripheral-to-drive-external-memories-stmicroelectronics.pdf so i'd guess if you are willing to go the distance, you can try getting chips like IS61WV5121...

If only the flash and RAM size is the difference, you take the ld file for ZE variant and copy it as ZG variant in which you adapt the RAM and ROM LENGTH parameters. Then edit the boards.txt file by copying this section to the next following lines in which you change the name, the parameters accord...

Hi!!! it is possible to buy this board: https://www.aliexpress.com/item/32741572112.html?spm=a2g0o.cart.0.0.4d8e3c00FcOLzz&mp=1 and replace the MCU with a 1Mb STM32F103ZGT6 chip? (with the same form factor LQFP144) Supposing that it can be done successfully, what changes are needed to add suppor...

try mine (I do not like interrupts by the way)

Im working on that... Im worried about the "invert logic" involved on using optos... I know I can fix it with code but I really like not to need that.
