Hi. I'm very new to this STM32 stuff. Only worked with PIC before. Tempted by all interesting Youtube examples wanted to tryout Chibios + UGFX so I went on and bought a MINI-STM32-V3 (STM32F103RB) with a 2.8TFT (ILI9325 - ADS7843) --- $21 on Ebay (dirt cheap) I manage to setup a Keil uVision5 project with Chibios and UGFX. The project compiles and runs great. I get a lot of warnings regarding the UGFX part while compiling my test project and I just wonder if it is safe just to ignore the warnings (and suppress them) or if it might haunt me later on when my project grows. I'm using UGFX "Tectu-ugfx-0ab22283645c.zip" which I hope is the latest and Chibios 3.0.2 *** Using Compiler 'V5.05 update 2 (build 169)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin' Rebuild target 'Mini STM32 V3' compiling hal.c... compiling pal.c... compiling can.c... compiling serial.c... compiling st.c... compiling chprintf.c... compiling memstreams.c... compiling uart.c... compiling usb.c... compiling serial_usb.c... compiling i2c.c... compiling spi.c... compiling hal_lld.c... compiling stm32_dma.c... compiling pal_lld.c... compiling serial_lld.c... compiling uart_lld.c... compiling st_lld.c... compiling usb_lld.c... compiling i2c_lld.c... compiling can_lld.c... compiling spi_lld.c... compiling main.c... ..\lib\ugfx\src/gdriver/gdriver.h(90): warning: #83-D: type qualifier specified more than once typedef const struct GDriverVMT const GDriverVMTList[1];
