Hello Sir,

I urgently want to have an idea whether due to the change of LCD from HT043C KunJjian to RK043FN48H-CT672B Rocktech in 32F746GDISCOVERY Board, is there any changes in the firmware due to this?

I would like to request for early response from your team, thanks for your support in advance.

Note: From the post only I got a point that RK043FN48H-CT672B Rocktech changed from HT043C KunJjian, 32F746GDISCOVERY B02 and C01 - what's the differen... - STMicroelectronics Community

Dear Kaouthar,

Thanks for clarifying, as this RK043FN48H-CT672B Rocktech is obselete hence can we change to RK043FN66HS-CTG Rocktech without any implication in the firmware of Discovery board?
